In Serbia, garlic is a defense against swine flu
Against the advice of their doctors, Serbians have turned to garlic as defense against the swine flu infection. Ever since the H1N! flu reached this country, the city of Belgrade has seen a rise in the market price of garlic. Many people are using garlic to fortify bodily resistance against the disease.
Aside from being widely used for cooking, garlic is regarded as an old remedy and a good luck charm. People munch on the white pungent cloves for its medicinal and nutritional properties--- hoping to protect themselves from the spread of the swine flu virus.
According to the Serbian health authorities, there are 270 documented cases and 8 deaths of the H1N1 pandemic so far. To counter viral infection, the government embarks on information campaign and has ordered the company Norvartis in Swtizerland for a supply of 3 million vaccines. The claims that garlic is an effective folk remedy against swine flu has no solid medical basis. (Photo Credit: Svadilfari) =0=

In spite of emergency declaration, USA suffers from H1N1 flu vaccine shortage
Of the 250 million doses of H1N1 flu vaccine purchased by the US government, only 40 million was expected by Center of Disease Control (CDC) to be available by mid-October. CDC director Dr. Thomas Friedman however said, in reality, only 22.1 million were shipped.
Despite the emergency declaration of Pres. Barack Obama on the flu pandemic, the delay in vaccine availability has led to scrambling for the few medicines available as swine influenza surges in 46 states as of mid October.
“The CDC identified at-risk groups, including pregnant women, children and young adults, and recommended they be vaccinated first. But in many cases, even physicians who have vaccine don't have enough to inoculate all their high-risk patients.”----amednews (11/02/09, Moyer, C. S.)
People waiting in community clinics are afraid of catching disease as they learn the vaccine is in short supply. Since the outbreak of the flu in April, there have been 1,000 deaths and about 2,000 hospitalizations.
The CDC suggests that patients with flu-like manifestations and showing severe symptoms should be given antiviral treatment. Since it takes time to make a lab diiagnosis of the flu and the maximum benefit of the antiviral is within the first 48 hours after the onset of symptoms, health authorities recommend that doctors start the medication even without the laboratory confirmation.
Vaccine production is accelerating to meet the demand. In response to CDC request, the Food and Drug Administration (FDA,) has approved the use of emergency intravenous antiviral peramivir for hospitalized patients with worse symptoms and do not respond to oral and inhalational anti-flu medications.
The public is encouraged to watch for advisories regarding the flu including particular attention to precautionary measures, prevention, and treatment regimens. In spite of the health preparations and citizen alerts conducted by health authorities, the vaccine delay is causing fear in the community.
Obviously the expectation on drug availability doesn’t match what has happened in the field. Doctors advise those with flu-like symptoms to stay away from people, wear masks, and bypass staying in patient’s waiting rooms---all to avoid spread of the disease. More cases of the virus infection are expected as the flu season goes in high gear. (Photo Credit: Ben Chau) =0=

Obama calls swine flu a national emergency
As predicted early in spring that the H1N1 flu pandemic will escalate to cause illness in fall and winter. Early this month, about 20% of school children in US have complained of flu-like symptoms, most of them are thought to be caused by the H1N1 virus. In addition, 7% of 10,000 adults surveyed reported manifestations of flu which had claimed the lives of 1,000 people in USA.
The spread of the swine flu has the potential to overtax the healthcare system as 46 out 50 states have reported rising influenza infections. Wordwide, it was reported 5,000 people have so far died of the disease since the first cases were identified in April. This prompted Pres. Barack Obama to declare a national flu emergency.
“The emergency declaration, which Obama signed late Friday, lets doctors and nurses temporarily bypass certain federal requirements so they can better handle a spike in influenza A(H1N1) patients. The declaration comes just days after Health Secretary Kathleen Sebelius warned that demand was outstripping supply of vaccine for the novel flu strain.”----AFP (10/24/09)
More than 1 million Americans have been downed by the H1N1 flu. Facing a vaccine shortage, the state of New York on Friday suspended the controversial ruling that health care personnel be vaccinated against the H1N1 flu by the end of November or face the possibility of job termination.
According to the Center for Disease Control (CDC) about 16.1 million doses of the H1N1 vaccine was ready for distribution and 11 million doses have already been passed on to state health authorities for use. In spite of this, it is believed that the distribution is already late to be able to cover individuals who truly need the vaccine. (Photo Credit: Fassbender, I./ Reuters/ Getty images) =0=

Which virus: seasonal flu or H1N1 virus?
The flu as reported by the Naga City Health Office (Bicol Mail, 07/16/09) could well indeed be cases of seasonal flu---the viral illness that makes rounds this year. However, I wonder if this flu described by Health officer Dr. Vito Borja is apart from the H1N1 which is the subject of concern, study and containment at this time.
It’s hard to differentiate between the seasonal and swine flu. The genomic features and clinical manifestations of both influenza viruses have points of overlaps. Therefore, without diagnostic confirmation as done in the Research Institute of Tropical Medicine (RITM) in Manila, no one will ever know for sure what the city is dealing with.
I believe residents of Naga and other towns including health care workers are eager to learn if confirmatory tests are done. Whichever virus may affect the population, greater surveillance is important to put into action the ways to prevent and control the spread of the disease.
The H1N1 flu, though generally benign and self-limiting, has the potential to mutate and transform into a vicious resistant disease. It poses health risks to the people like the seasonal flu. (Photo Credit: CDC) =0=

Natural defense against H1N1 flu among Filipinos & the potential economic impact of the pandemic in poor countries
In spite of the aggressive surveillance of the swine flu, the pandemic has basically spilled in the community raising the number of those stricken ill to 604 as of June 24, 2009. The rapid transmission in Metro Manila is expected to increase as more cases are identified. Nobody knows how the disease spread will end.
In a Wall Street blog by Shirley Wang on June 23, 2009, the World Bank has estimated that the pandemic may bring far-reaching negative economic impact in countries that are poor. In Mexico where the swine influenza started, it is estimated that tourism has dropped to 43%. Citing a 2006 study, World Bank says that the low end impact of the illness is a contraction of about 0.7% of global GDP similar to the Hong Kong flu of 1968-69. A high end impact can contract global GDP by 4.8% like the 1918-1919 Spanish flu. This is something to watch when the next flu season arrives. Countries with limited funds and facilities to fight the disease are most vulnerable to get the worst effects of the pandemic.
If greater than 80% of the illness is self-limiting---i.e. the viral infection heals by itself, then the main body defense is likely the person’s immunity. A breakdown of the immune response in persons with chronic illnesses or conditions of immunosuppression will therefore put a person at risk of getting sick or dying. People catching the virus at the same time disrupt the workplace. Productivity is undermined when illness prevents people from working.
If the new virus mutates to a deadly form, the picture may change for the worse when the genetic change turns towards the acquisition of more virulence. Influenza viruses which acquire traits of greater virulence have the capacity to sicken more people.
The techniques of prevention still apply to avoid getting ill. Constant hand-washing, educational seminars to understand the nature of the disease, avoiding huge crowds and quarantine of those suspected of having disease appreciably lowers the number of infection. Case finding and treating those who harbor signs of illness on time will help avoid transmission in the community.
The use of seasonal flu vaccine (vs. the vaccine against the new swine strain) is not expected to protect against the H1N1 flu and thus may end up just a wastage of money. The vaccine which will accomplish protection for swine flu is still under development in laboratories abroad.
Anti-virals (Tamiflu) may be used to ameliorate the signs of the disease, but their efficacy to foil the new H1N1 flu is basically equivocal. Dirty contaminated masks that are repeatedly used may serve as a soil on which the swine flu can grow if not discarded in a timely fashion. (Photo credit: Lucher) =0=

Philippines reports first death of swine flu
At a time when the country registered 445 cases of H1N1 flu, the first mortality to the viral infection came to a 49 year old woman who suffered from complications of congestive heart failure following a heart attack.
According to Dr. Yolanda Oliveros, director for the National Center for Disease Prevention and Control, the victim who had pre-existing heart disease developed signs of flu on June 17, 2009. This underscores the higher risk of mortality among those with medical conditions which lower the resistance against flu----those who are immunocompromised or suffer from chronic illnesses like diabetes, heart disease, HIV/AIDS, asthma, cancer and the likes.
Related to the flu pandemic, 8 more schools temporarily closed after some of their students contracted the swine flu. At the rate the infection spreads, Dr. Lyndon Lee Suy testified to the house hearing that it’s possible 25% (about 22 million) of the population can be stricken by the illness. The virus has the potential to transform through genetic changes into a strain of greater virulence and lethality. (Photo Credit: Benedicte Desrus) =0=
============================================================
Linkage between poverty and the influenza epidemic
The startling rise of H1N1 flu cases to more than 300 in a matter of days in the Philippines makes Filipinos to look into why this happens. The rapid spread of the illness is easy to understand considering how poor the country is, says the Health Action Information Network (HAIN,) non-government organization (NGO.)
Dr. Delen de la Paz, executive director of HAIN believes the poor Filipinos die early because of lack of nutrition which leave them susceptible to the complications of disease. According to the 2006 Family Income and Expenditure Survey, the poorest 1.7 million families in the Philippines try to make both ends meet with an average budget of P18 per day (less than 50 cents/day.)
A case of point is the worsening flu problem together with other diseases endemic in the country. Dr. de la Paz has this to say:
“Bakit ba nagiging pneumonia ang influenza? It starts with viral infection that is supposed to be self-limiting in seven days. Pero dahil walang pambili ng gamot, nagkakaroon ng secondary bacterial infection. Lumalala na ang sakit pero nagtatrabaho pa rin. Ang sweldo kulang pang pambili ng pagkain, so paano na ang gamot?"----GMA News TV (06/06/09, Sabangan, A R.)
Dr. de la Paz criticizes the government for its superficial handling of the swine flu epidemic. According to her, the Department of Health (DOH) has advised Filipinos to raise body resistance against infection by having at enough sleep and rest, adequate exercise, control stress, have good hydration and eat nutritious foods. But Dr. de la Paz says, this simply can’t be done if one is poor, underpaid, overworked, hungry and malnourished.
In response to the criticism, Yolanda Oliveros, director of the National Center for Disease Prevention and Control says the DOH tries to address the problem by campaigning for an increase of the agency’s budget from only P11 billion three years ago to today’s P20 billion---funds most needed to expand medical coverage, purchase more medicines and hospital equipment, and improve the delivery of health services in the country.(Photo Credit: Claude Barutel) =0=

Politics of Health: Give the flu vaccines to those who need them most
The number of H1N1 flu infection ominously jumped from 111 to 147 cases and health authorities reported brisk community transmission in Nueva Ecija----suggesting that more cases are cropping up and the flu is getting harder to control.
As a response, the government said 8,000 Makati City employees will be given free flu shots on Monday to prevent the seasonal flu, not the H1N1 viral infection. The government thinks mass vaccination against the common flu at a cost of P2.8 million will help track down by “elimination” those with swine flu. But health authorities know that giving the vaccine doesn't completely assure seasonal flu will be avoided.
“We have prioritized the immunization against seasonal or common flu of our city workers, especially our frontline and field workers, not only to strengthen their defenses against respiratory diseases, but also to help us in promptly identifying possible cases of A(H1N1),” Makati Mayor Jejomar Binay said.---Philippine Daily Inquirer (06/14/09, Lopez, A.)
Really?
The seasonal flu vaccine is not expected to be effective in preventing the H1N1 flu. At best, the justification that swine flu can be detected by “elimination” is faulty because there are many illnesses which present with flu-like symptoms. If one means to control the viral disease, it’s not by “elimination.” Doctors need the right diagnosis, even if influenzas in general have essentially the same treatment.
To identify H1N1 flu or seasonal flu, a lab test like the one done at the Research Institute of Tropical Medicine (RITM) must be done. This makes one to consider if Mayor Binay’s decision to administer the vaccine is in line with good medical judgment. Why don't politicians like Binay leave the medical decisions to Dr. Francisco Duque III and the Department of Health (DOH?)
Government employees, unless they are in the high risk group, hardly qualify as the priority group to get the vaccines. Though workers may receive them, the government in triaging patients, must give the vaccines to those who need them most as shown below. On the process of production, it will take sometime before the new H1N1 vaccine will be readily available in the market:
2008-09 INFLUENZA PREVENTION & CONTROL RECOMMENDATIONS
Center for Disease Control
Vaccination of all children aged 6 months–18 years should begin before or during the 2008–09 influenza season if feasible, but no later than during the 2009–10 influenza season. Vaccination of all children aged 5–18 years is a new ACIP recommendation.
Children and adolescents at high risk for influenza complications should continue to be a focus of vaccination efforts as providers and programs transition to routinely vaccinating all children and adolescents. Recommendations for these children have not changed. Children and adolescents at higher risk for influenza complication are those:
•aged 6 months–4 years;
•who have chronic pulmonary (including asthma), cardiovascular (except hypertension), renal, hepatic, hematological or metabolic disorders (including diabetes mellitus);
•who are immunosuppressed (including immunosuppression caused by medications or by human immunodeficiency virus);
•who have any condition (e.g., cognitive dysfunction, spinal cord injuries, seizure disorders, or other neuromuscular disorders) that can compromise respiratory function or the handling of respiratory secretions or that can increase the risk for aspiration;
•who are receiving long-term aspirin therapy who therefore might be at risk for experiencing Reye syndrome after influenza virus infection;
•who are residents of chronic-care facilities; and,
•who will be pregnant during the influenza season.
Note: Children aged <6 months should not receive influenza vaccination. Household and other close contacts (e.g., daycare providers) of children aged <6 months, including older children and adolescents, should be vaccinated.
Annual recommendations for adults have not changed. Annual vaccination against influenza is recommended for any adult who wants to reduce the risk for becoming ill with influenza or of transmitting it to others. Vaccination also is recommended for all adults in the following groups, because these persons are either at high risk for influenza complications, or are close contacts of persons at higher risk:
•persons aged >50 years;
•women who will be pregnant during the influenza season;
•persons who have chronic pulmonary (including asthma), cardiovascular (except hypertension), renal, hepatic, hematological or metabolic disorders (including diabetes mellitus);
•persons who have immunosuppression (including immunosuppression caused by medications or by human immunodeficiency virus);
•persons who have any condition (e.g., cognitive dysfunction, spinal cord injuries, seizure disorders, or other neuromuscular disorders) that can compromise respiratory function or the handling of respiratory secretions or that can increase the risk for aspiration;
•residents of nursing homes and other chronic-care facilities;
•health-care personnel;
•household contacts and caregivers of children aged <5 years and adults aged >50 years, with particular emphasis on vaccinating contacts of children aged <6 months; and,
•household contacts and caregivers of persons with medical conditions that put them at high risk for severe complications from influenza.

WHO declares H1N1 flu a pandemic; RP’s cases rise to 92
After weeks of weighing in the right time to declare a pandemic, the World Health Organization (WHO) finally ruled on Thursday, June 11, 2009 that the swine flu which caused illness and death to 27,737 and 141 people respectively, had reached pandemic level. It’s the first pandemic to be categorized in more than 40 years.
The new viral infection which has spread to 74 countries usually manifests as a mild illness and uncommonly cause death. Health authorities however emphasize the need for prevention and more caution. The virus is highly transmissible and quite unpredictable. It has a potential to transform and grow in virulence as it affects different populations of the world.
The decision to raise the disease to level 6 underscores the need for vigilance, prevention and control by various governments. The pandemic will spur the production of vaccines and drugs to fight the disease. It will require more money to keep the illness under control.
The raising the alert to the highest level coincides with the increase of cases in the Philippines to about 100, the highest number of those sickened so far by the swine infection in Southeast Asia. With the unpredictability the infection, one can just hope that the effort by the health authorities will lessen the incidence, mortality and morbidity of the pandemic in the country.
What is a pandemic?
A pandemic is a new infectious disease that spreads around the world.
The best recent example of a pandemic is AIDS, caused by a virus new to humans: HIV.
Seasonal flu viruses spread around the globe and cause 250,000 to 500,000 deaths each year -- including some 36,000 annual deaths in the U.S. But seasonal flu isn't considered a pandemic, even though the viruses that cause them change a little from season to season.
One of the seasonal flu viruses is a type A H1N1 virus. But the type H1N1 swine flu virus that appeared in 2009 is an entirely different virus. It carries genes from swine flu viruses from North America and Eurasia as well as genes from human and bird flu viruses.
Humans have never before been infected with this virus. That means that nobody is immune, although some people born before 1957 may have been exposed to an ancestor virus that could possibly give them a small degree of protection.
Because the vast majority of people are vulnerable to the 2009 H1N1 swine flu virus, because it spreads easily from person to person, and because the virus is spreading in communities in different parts of the world, the current swine flu has reached pandemic proportions.
Flu pandemics occur regularly. That's because there are many kinds of flu viruses in animals (mostly birds), but so far only a few have evolved the ability to infect humans. There were three flu pandemics in the 20th century: in 1918, in 1957, and in 1968. Source: WebMD (06/11/09, Daniel J. DeNoon; Louise Chang, MD)
What is WHO doing to respond?
"WHO continues to help all countries respond to the situation. The world cannot let down its guard and WHO must help the world remain and become better prepared.
WHO's support to countries takes three main forms: technical guidance, materials support, and training of health care system personnel.
WHO's primary concern is to strengthen and support health systems in countries with less resources. Health systems need to be able to prevent, detect, treat and mitigate cases of illness associated with this virus.
WHO is also working to make stocks of medicines (such as antivirals and antibiotics) and an eventual pandemic vaccine more accessible and affordable to developing countries.
Both antivirals and vaccines have important roles in treatment and prevention respectively. However, existing stocks of antivirals are unlikely to meet the demand. And vaccines may be developed, but it will some months.
Therefore, rational use of the limited resources will be essential. And medicines are only part of the response. WHO is also deploying diagnostic kits, medicines and masks and gloves for health care settings, teams of scientific experts, and medical technicians so countries in need can respond to local epidemics.
A pandemic sets national authorities in motion to implement preparedness plans, identify cases as efficiently as possible, and minimize serious illness and deaths with proper treatment.
The goal is to reduce the impact of the pandemic on society."---Source: www.who.int (Photo Credit: Amanda Ruth) =0=

WHO about to declare H1N1 flu as a worldwide pandemic
In spite of close monitoring and containment, the H1N1 virus has spread to sicken render about 20,000 individuals in 66 countries. The World Health Organization (WHO) is weighing in if it’s the right time that the viral infection be called a pandemic, the highest level of threat for a highly transmissible disease.
At present, the spread of the disease is mostly among travelers, in schools, and close contacts, but not much within the community. However, with the start of winter in the Southern Hemisphere, health authorities worry if the swine flu will infect more people than last year’s similar strain (H1N1 flu) which is resistant to the anti-viral medication Tamiflu.
The WHO is now "getting closer" to declaring the outbreak had reached phase six, the highest level on their alert scale.---said WHO’s flu chief Keiji Fukuda. Guardian.co.uk (06/03/09 Carrell, S.)
The same consideration has been reported in New York Times (06/03/09, A9, McNeil)
To declare the flu as a pandemic requires many considerations. People who don’t fully understand the disease may panic so the logistics to inform and prepare them must be put in place. In a pandemic, there may be trade and travel restrictions that my impact the economy of a country. A bigger budget and personnel to fight the illness must be readied.
The WHO is preparing an additional $500 million to aid poor countries. Pres. Barack Obama has asked the US legislature for $2 billion in anticipation of a full blown pandemic.
The virus which behaves like a mild seasonal flu at this time may mutate, grow in virulence and cause more deaths than generally expected as it moves along. With all these considerations, WHO calls on its experts---public health officials and academics to think what is best in the fight against the infection. They’re trying to figure if raising the level of disease threat to 6 is warranted and will be for the benefit of the people. (Photo Credit: Healthcare without Harm) =0=

June 3, 2009: Philippine Swine Flu Update

As of June 3, 2009, the WHO tally puts the number of swine flu infections to 19, 273 and 117 deaths in 66 countries. About half of the number of cases have been confirmed in the United States. (Photo Credit: Bendicte Desrus)
UPDATE: On June 4, 2009, 6 more positive H1N1 flu sufferers were reported by Dr. Francisco Duque III of DOH, bringing a total of 28 people having contracted the disease. =0=
=========================================================
RP reports its first H1N1 virus infection
Based on the tally of the World Health Organization (WHO,) the swine flu spreading throughout the world has reached 11,168 and 86 deaths as of May 22, 2009. This coincides with the first case confirmed in the Philippines which joins at least 38 countries having the disease.
The Department of Health (DOH,) reported that the swine flu-positive 11 year-old girl identified by the laboratory of the Research Institute for Tropical Medicine(RITM) arrived on May 18, 2009 from USA and Canada where many swine infections have been reported. She is presently quarantined in an effort to contain the virus from infecting the general population.
“The government will conduct contact tracing to identify and diagnose individuals who might have come into contact with the infected girl. Health authorities will also check the plane boarded by the girl for traces of the disease.”--- GMA TV News.com (05/21/09 Balagtas-See, A)
Advising the public to be calm and be mindful of the preventive measures advised by health authorities, the DOH reminds the public of the need for vigilance. Filipinos must not be complacent as the virus easily mutates; it has the potential to cause significant morbidity and mortality which can affect the nation's economy. Pharmaceuticals are still on the process of making a the H1N1 flu vaccine, but it will take a few months before it will be available. =0=

Pig flu spreads to Italy
While the temptation to be complacent is there to stifle the fight against the swine influenza, the first case of infection is reported in Italy.
The Italian who traveled from Mexico was hospitalized in Massa near Florence after coming down with flu on April 23, 2009. With treatment, he apparently recovered. Anti-viral medications were given to his relatives as disease prevention.
Raising the alert level to 5 which indicates that a pandemic is likely, the viral illness cause fear in all corners of the globe. The World Health Organization (WHO) has closely monitored the spread of the disease which is present in at least 15 countries. In USA, 143 cases are confirmed in 20 states. In Mexico, the total number of persons infected has jumped to 443, including several deaths. (Photo Credit: shhexycorin) =0=

May 2, 2009: Update of swine influenza; Hongkong reports its first case
The World Health Organization (WHO) has raised its vigilance to level 5---an indication that the swine influenza infection has actively propagated through an efficient human-to-human infection causing more people to fall ill. Still expected to rise, the number of confirmed H1N1 pig influenza infection has reached 331 as of May 1, 2009. If uncontrolled, the disease is on its way to be a pandemic.
In a matter of days, what was originally confined to Mexico and United States has spread to 10 countries with confirmed infection: Austria (1), Canada (34), Germany (3), Israel (2), Netherlands (1), New Zealand (3), Spain (13), Switzerland (1) United States (109), Hongkong (1) and Great Britain (8). Closures of schools and cancellation of public gatherings, surveillance of travelers for febrile illness, educational campaign to prevent infection, and the use of anti-flu drugs are among the measures being done to stop the contagion's spread.
Hongkong recently confirmed it's first case of swine influenza diagnosed from a Mexican tourist. Quarantine procedures were quickly set in place for about 300 individuals who were in close contact with the ill person. (Photo Credit: Reuters/ Lee, Jin-man)=0=

The march of the pig virus
Across the borders of Mexico the fast-moving virus has proven its efficiency of causing alarm across the globe. The World Health Organization (WHO) raised its level of vigilance to level 4 indicating that the disease is highly transmissible among human beings.
The United States declared a public health emergency to coordinate the Department of Homeland Security’s response to the changing health threat. Russia, Hong Kong and Taiwan said they would isolate travelers showing symptoms of the virus. Europe urged people to forgo non-essential travel especially in the disease epicenter.
CDC recommendations on Prevention
1. Wash your hands regularly with soap and water, especially after coughing or sneezing. Or use an alcohol-based hand cleaner.
2. Avoid close contact with sick people.
3. Avoid touching your mouth, nose, or eyes.
With the uncertainty of where the march of the disease will go, countries like the Philippines banned the import of pork from Mexico and the United States. Asian countries such as Singapore, Thailand, Japan, Indonesia and the Philippines started active screening of with flu-like symptoms travelers in their respective airports.
To date, there are at least 6 countries with the pig flu infection----Mexico, USA, Canada, New Zealand, Spain, and Israel. It is likely more places will confirm swine infections. There are about 2,000 downed by the illness with about 150 deaths. From extrapolations from past pandemics, in a worst case scenario, a large-scale illness can overwhelm care-givers and hospitals and cause the death of 2% of those affected, perhaps 2 million in USA alone.
The spread of the flu had negatively affected business and the economy. The world market fell yesterday amid threats of a pandemic and instability of the financial markets. Mexico had so far the most number of flu victims and it suffered the aftermaths of a faltering economy, drug wars, and a recent earthquake. Its major dollar earner, the tourism industry, slowed for lack of visitors.
There are those who ask why the US-Mexican border has not been closed---the disease adding to the problem of illegal aliens in the United States taxing the healthcare system. The active surveillance of suspected carriers seen in Asia is absent in America. The Obama government has no plan to halt school, ban large gatherings in public places considered mixbowls of infection.
Top level positions in the CDC and Department of Health and Human Services (HHS) still need people to decide on encompassing health decisions especially if the situation deteriorates. With the illness out of the box people criticized Mexico for not doing enough in controlling the disease at the onset.

Mexico’s new swine-avian-human flu worries health experts of global pandemic
Mexico closed down schools, museums and movie houses on Friday, April 24, 2009 as nearly a thousand suspected cases of influenza were reported to sicken people and at least 61 died. The disease which may be transmitted from animals (zoonotic infection) has worried Mexican authorities for its killing power and its adverse effects on tourism, a major source of revenue for the country struck by economic downturn, drug wars, and narcotics trade.
“Mexico's Health Secretary, Jose Cordova, said only 16 of the deaths have been confirmed to have been caused by the new strain, through testing at government laboratories. Samples from 44 other people who died were still being tested. The health department put the total number of people sickened by the virus at around 943 nationwide.” ----AP/ Philstar (04/24/09)
To contain the spread of the disease, the Mexican government urged the public to shun large crowds and avoid close contacts with people. Those with fever, cough, a sore throat, muscle and joint pains are advised to see a doctor and stay at home. The people responded with certain fear and confusion.
“Most of Mexico’s dead were young, healthy adults, and none were over 60 or under 3 years old, the World Health Organization said. That alarms health officials because seasonal flus cause most of their deaths among infants and bedridden elderly people, but pandemic flus — like the 1918 Spanish flu, and the 1957 and 1968 pandemics — often strike young, healthy people the hardest.”--- New York Times (04/24/09, Lacey, M.; McNeil, D. Jr.)
Eight (8) non-fatal flu similar to those caused by this new Mexican strain were diagnosed in the southwest United States prompting health authorities to sound an alarm. It is unknown how many more will go down with the disease.
According to Center for Disease Control (CDC,) which monitors the disease, the new strain of flu contains a combination of gene sequences of pig, bird, and human influenza.
“Given how quickly flu can spread around the globe, if these are the first signs of a pandemic, then there are probably cases incubating around the world already, said Dr. Michael Osterholm at the University of Minnesota.” ----Newsnet5.com / AP (04/42/09, Stevenson, M)
It is said the flu seems responsive to the two drugs available: Tamiflu and Relenza. The medicines need to be taken early during the illness to get the best benefit.
Health authorities scramble to control the disease which has the potential to spread as a pandemic. It isn't known if the vaccination given last fall and winter confers protection from this new viral strain which is transmissible from person to person. Neither is it understood how the genetic mixture of the virus came to be. Frequent hand washing and covering one’s mouth during a sneeze or cough are among the common precautions to prevent the spread of the disease. (Photo Credit: Opiado)
