Protection From H1N1 Flu Is The Same As From Seasonal Flu

Protection From H1N1 Flu Is The Same As From Seasonal Flu.
The romance H1N1 flu seems to dole out many characteristics with the seasonal flu it has fundamentally replaced, a original muse about indicates. "Our results are further confirmation that 2009 pandemic H1N1 and seasonal flu have nearly the same communication dynamics viagra. People seem to be similarly catching when bad with either pandemic or seasonal flu, and the viruses are appropriate to spread in similar ways," said Benjamin Cowling, contribute to author of a investigate appearing in the June 10 issue of the New England Journal of Medicine.

The approving hearsay is that this means the preventive measures health authorities have been recommending, such as recurring hand washing, should be equally operative against pandemic flu. "Influenza is very difficult to contain, but around measures including the availability of pandemic H1N1 vaccines should be able to appease the worst of any further epidemics," added Cowling, who is an aide-de-camp 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 imperious for H1N1. Eight percent of the household contacts also demolish hatred with the H1N1 virus, about the same dispatching estimate 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 model of solid sickness, were also comparable for the two types of flu. The "attack rate" (meaning the share of society in the absolute population who get sick) for H1N1 was higher than that for seasonal flu and the inconsistency was most pronounced among children. The authors hypothesized that this might be due to the deed that younger consumers seem to have lower natural immunity to the virus.

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

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

A moment weigh in the paper found that giving Tamiflu prophylactically (as a barring measure) to ancestors confined in adjacent quarters - in this case, navy installations - seemed to stay outbreaks. Flu is also more likely to spread and bed-cover faster in enclosed places such as schools and hospitals, in summing-up to military facilities.

In this study, Tamiflu was given to 1100 personnel out of a amount to 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 child who came down with H1N1 grow the virus to only 0,11 additional individuals after the intervention, versus almost two kinsmen before read this. Although a vaccine is obtainable for the 2009 H1N1 pandemic strain, Tamiflu might be an privilege in areas where the vaccine is not probably obtainable, stated the authors, who are with the Singapore Ministry of Defence and the National University of Singapore.
