Protection From H1N1 Flu Is The Same As From Seasonal Flu

Protection From H1N1 Flu Is The Same As From Seasonal Flu.
The new H1N1 flu seems to stake many characteristics with the seasonal flu it has mostly replaced, a recent on indicates. "Our results are further confirmation that 2009 pandemic H1N1 and seasonal flu have like transmittal dynamics online. People seem to be similarly catching when mischief with either pandemic or seasonal flu, and the viruses are appropriate to spread in similar ways," said Benjamin Cowling, bring on author of a enquiry appearing in the June 10 issue of the New England Journal of Medicine.

The high-minded information is that this means the preventive measures health authorities have been recommending, such as normal hand washing, should be equally useful against pandemic flu extrem long lips. "Influenza is very difficult to contain, but present measures including the availability of pandemic H1N1 vaccines should be able to tone down the worst of any further epidemics," added Cowling, who is an aid 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 egregious for H1N1 your domain name. Eight percent of the household contacts also strike down bad with the H1N1 virus, about the same forwarding assess 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 standard of realistic sickness, were also alike for the two types of flu. The "attack rate" (meaning the shape of kinfolk in the undiminished population who get sick) for H1N1 was higher than that for seasonal flu and the dissimilitude was most pronounced among children. The authors hypothesized that this might be due to the truth that younger tribe seem to have lower natural immunity to the virus.

The patients in this scrutiny who were given oseltamivir (Tamiflu) did seem to have reduced antibody levels. "This would suggest that perchance oseltamivir may effect in a less vigorous immune response than public who are not treated with this drug ," said Dr John J Treanor, professor of panacea 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 signification of oseltamivir on antibody response. This should be looked at more closely. It's potentially impressive in terms of long-term susceptibility to re-infection. Susceptibility might be bizarre in someone treated with oseltamivir who is not vaccinated. They might have enhanced susceptibility".

A relocate sanctum in the weekly found that giving Tamiflu prophylactically (as a inhibition measure) to community confined in sign quarters - in this case, martial installations - seemed to quell outbreaks. Flu is also more likely to spread and coverlet faster in enclosed places such as schools and hospitals, in summation to military facilities.

In this study, Tamiflu was given to 1100 personnel out of a add up 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 human who came down with H1N1 quilt the virus to only 0,11 additional individuals after the intervention, versus almost two populace before continued. Although a vaccine is on tap for the 2009 H1N1 pandemic strain, Tamiflu might be an way out in areas where the vaccine is not without difficulty obtainable, stated the authors, who are with the Singapore Ministry of Defence and the National University of Singapore.
