That 90% of cases of influenza are the influenza virus A (H1N1) influenza seasonal means that were displaced? Any claim would be premature to respiratory viruses is still several weeks to move.
But there is a new trend in the behavior of the virus, according to analysis at the Institute Malbrán laboratories and medical centers associated with universities. "We have units in all provinces sentries who are doing a sampling of the virus in cases of influenza-like illness [TSI] to make the epidemiological profile. We see that the presence of the H1N1 is high on almost flu-like syndromes. An extrapolation on the cases influenza reported would suggest that nine out of ten are influenza A, "told the nation on maximum Diosque pediatrician, secretary of Health Promotion and Programs of the Ministry of Health.
Still, the official, who specializes in health economics and management, said that "technically" too early to know whether the new strain will displace the others. "We have fewer cases of seasonal influenza in previous years, but it is a half-truth. It would be unwise even to make an assessment because of a delay in reporting epidemiological, almost throughout the country," he added.
According to epidemiological data from the health portfolio, in 2007 there were 1,258,704 cases of flu in the country, while in 2008 there were 1,186,552 people who died this year 3600, the number of reported cases of TSI from the public sector to last Friday was 288,155, without discriminating between types of flu.
"The cases reported in the country are within the expected values according to historical records," concluded the analysis of the situation room of the Directorate of Epidemiology of the Ministry of Health. But it warns that there is a delay in notification, which comes to 8.4 weeks in the middle of the country.
"In a small study shows this month, in our laboratory, was 90-95% for influenza A. It is normal to happen during a pandemic is possible and that when more cases accumulate, it remains so, but not yet know, "said Dr. Paul Bomvehi, president of the Argentine Society of Infectious Diseases and Head of Infectious Diseases CEMIC.
Moreover Sagasta Dr. Carlos Martinez, a professor of epidemiology at the University of Salvador, raised: "It could give a paradox because those over 55 contribute about 70% of mortality from seasonal influenza, and this almost is not happening. The virus affects the youngest and mortality is not as high as that of seasonal influenza. "
