p Like everyone else, students, teachers and other staff should stay home if they are feeling sick, the WHO said. Australia on Friday reported its first case of drug-resistant H1N1, which would raise the tally to 22. On Thursday, the U. But last month, the Public Health Agency of Canada said there is no point closing schools unless the severity of swine flu cases increases, if there aren’t enough teachers coming to work or many students are sick. !–more– If students congregate in a setting other than a school, they will continue to spread the virus, and the benefits of school closure will be greatly reduced, if not negated, the statement said. The H1N1 virus has killed nearly 3,000 people since emerging last April. The number of reported cases resistant to the antiviral Tamiflu or oseltamivir is 21, the agency said in its weekly report. It’s only worth closing schools to slow the spread of the H1N1 pandemic virus during the earliest stages of an outbreak, the World Health Organization said Friday. S. [S]chool closure has its greatest benefits when schools are closed very early in an outbreak, ideally before one per cent of the population falls ill, the UN health agency said in a statement advising its 193 member states. It is now the main flu strain circulating in both hemispheres, according to the WHO. Health officials are watching for signs that the virus may be mutating in a way to make the antiviral ineffective.
Health officials are concerned that hospitals and health facilities could be overwhelmed by people needing medical care during the peak of the global outbreak. Under ideal conditions, school closure can reduce the demand for health care by an estimated 30 to 50 per cent at the peak of the pandemic. So far, Tamiflu and Relenza, another antiviral, are considered effective against the H1N1 virus. The United States and Britain have advised schools to stay open except under exceptional circumstances, given that it’s thought that school closures do not help reduce the number of cases but spread them out over a longer time while keeping parents, including health care workers, away from work. Centers for Disease Control and Prevention reported what could be Tamiflu-resistant flu virus spreading from person to person. Schools should also designate spaces to isolate those who fall ill while at school. Proper cleaning, ventilation and measures to reduce crowding are recommended, along with hand hygiene and repiratory etiquette, WHO said. WHO also said Friday that swine flu has claimed at least 3,205 people worldwide. It usually causes mild symptoms, but pregnant women and those having underlying medical conditions are at higher risk. Most resistant viruses were found in people who had been taking the antiviral to prevent infection or treat it. During school closures, officials should also try to limit students from congregating elsewhere socially, such as malls.
