Protection From H1N1 Flu Is The Same As From Seasonal Flu

Protection From H1N1 Flu Is The Same As From Seasonal Flu.
The tale H1N1 flu seems to cut many characteristics with the seasonal flu it has basically replaced, a new study indicates. "Our results are further confirmation that 2009 pandemic H1N1 and seasonal flu have equivalent transmission dynamics neend ki goli online. People seem to be similarly catching when ill with either pandemic or seasonal flu, and the viruses are likely to spread in similar ways," said Benjamin Cowling, advance author of a study appearing in the June 10 issue of the New England Journal of Medicine.

The cogent news is that this means the preventive measures health authorities have been recommending, such as customary hand washing, should be equally effective against pandemic flu philippines. "Influenza is very difficult to contain, but bruited about measures including the availability of pandemic H1N1 vaccines should be able to mitigate the worst of any further epidemics," added Cowling, who is an subordinate professor at the School of Public Health at the University of Hong Kong.

Cowling and his colleagues followed 284 household members of 99 individuals who had tested arrogant for H1N1. Eight percent of the household contacts also demolish ill with the H1N1 virus, about the same transmission rate as seen for the seasonal flu (9 percent), the researchers found.

Viral shedding (when the virus replicates and leaves the body), as well as the figure of tangible sickness, were also similar for the two types of flu. The "attack rate" (meaning the correspondence of people in the entire population who get sick) for H1N1 was higher than that for seasonal flu and the dissimilarity was most pronounced among children. The authors hypothesized that this might be due to the fact that younger kinfolk seem to have lower natural immunity to the virus.

The patients in this study who were given oseltamivir (Tamiflu) did seem to have reduced antibody levels. "This would suggest that perchance oseltamivir may result in a less vigorous immune response than settle who are not treated with this drug ," said Dr John J Treanor, professor of pharmaceutical and of microbiology and immunology at the University of Rochester Medical Center.

So "That is very different from studies looking at seasonal flu, where there doesn't appear to be any upshot of oseltamivir on antibody response. This should be looked at more closely. It's potentially significant in terms of long-term susceptibility to re-infection. Susceptibility might be different in someone treated with oseltamivir who is not vaccinated. They might have enhanced susceptibility".

A sponsor study in the journal found that giving Tamiflu prophylactically (as a frustrating measure) to people confined in close quarters - in this case, air force installations - seemed to stem outbreaks. Flu is also more likely to spread and dispensation faster in enclosed places such as schools and hospitals, in addition to military facilities.

In this study, Tamiflu was given to 1100 personnel out of a downright of 1175 personnel. Before the intervention, 6,4 percent of individuals were infected, compared with only 0,6 percent after Tamiflu was introduced. On average, a soul who came down with H1N1 span the virus to only 0,11 additional individuals after the intervention, versus almost two people before proextenderusa.men. Although a vaccine is close by for the 2009 H1N1 pandemic strain, Tamiflu might be an option in areas where the vaccine is not indubitably obtainable, stated the authors, who are with the Singapore Ministry of Defence and the National University of Singapore.
