Which virus: seasonal flu or H1N1 virus?

7/21/2009 | Posted by mesiamd | Edit Post

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.

Politics of Health: Give the flu vaccines to those who need them most

6/15/2009 | Posted by mesiamd | Edit Post

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.

2nd H1N1 flu case reported in the Philippines

5/25/2009 | Posted by mesiamd | Edit Post

Because of the time lag between the exposure to influenza and the moment manifestations of the infection arise, it’s only now that the 50-year old Filipina who arrived as a balikbayan from USA is confirmed as the second case of swine flu infection in the country. The first case is a 10 year-old child who also came home from a trip abroad. She is reported to have fully recovered from the illness.

The Research Institute for Tropical Medicine (RITM) announces the woman tested positive for the H1N1 virus though it appears that she has been recovering since she experienced having cough and fever, one day after her arrival from USA.

“Since monitoring started on May 1, the DOH has placed 105 individuals under observation, with 88 already being found negative and 15 have pending laboratory test results.”---Malaya (05/23/09, Naval, G)

Though there is no reason to panic, the viral infection that has affected close to 12,000 individuals in 43 countries is a source of concern. The new strain of viral infection has the capacity to kill and is still under study. Nobody knows how the virus with a propensity to mutate and assume more virulence will behave when it spreads in different countries as the seasons change.

Preventive measures such as frequent handwashing, covering one’s nose and mouth when sneezing and coughing, avoiding hand contact with people as advised by the Department of Health are in place.

The World Health Organization urges nations to push for pandemic preparedness and advices pro-active fight against the disease while only a few individuals have been stricken ill of the disease.(Photo Credit: CDC)=0=

RP reports its first H1N1 virus infection

5/22/2009 | Posted by mesiamd | Edit Post

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=

Quarantine of 3 possible Swine flu sufferers in Cebu

5/06/2009 | Posted by mesiamd | Edit Post

It’s a waiting game for three individuals who were quarantined in Cebu on suspicion that they harbor the H1N1 flu virus. A Filipino who was detected to be running fever by thermal scan at Cebu Airpot was isolated together with his wife after they arrived from their trip which brought them to Ireland, Hongkong then to Cebu via Cathay Pacific Fight.

They were sequestered in quarantine rooms at the Vicente Sotto Memorial Medical Center pending the results of their laboratory tests crucial in determining if they have the pig flu. With them was an Englishwoman who voluntarily came to the hospital on May 4, 2009 to complain of cough and colds after visiting Mexico and Hongkong, places where the swine virus had been reported.

Renan Cimafranca, the head of the Regional Epidemiology Surveillance Unit said that the public will be notified of the laboratory tests sent to the DOH’s Research Institute of Tropical Medicine (RITM )in Alabang on the three individuals as soon as they are available. Although the swine influenza seems to behave like the seasonal flu, caution and vigilance are advised because the behavior of the new flu strain isn’t completely known.

Since no swine flu has so far been detected in the Philippines, the Department of Education (DePEd) has no plan to interrupt the schedule of opening of classes in June. Health authorities in Cebu are confident of their readiness to tackle the H1N1 virus infection after learning from their experience in controlling Severe Acure Repiratory Syndrome (SARS) in 2002-2003.
