we are most worried about is, will not be a serious influenza pandemic. This also need not panic. Whether flu pandemic, not only to look at will the emergence of a new influenza virus variation and also look at this kind of variation will not increase the spread of the virus, pathogenic ability, resistance ability. Fortunately, the current virus monitoring results show that this year’s flu virus also found no such change.

recently often listen to the people and asked the question: influenza vaccines have no? Do you want to eat the antiviral drug tamiflu to prevent flu?

just said the flu viruses mutate easily, so the world health organization (WHO) every year for the next popular season which predict flu strains, and according to the forecast results put forward the recommendations of the global influenza vaccine strains, global vaccine enterprise on the basis of the production of flu vaccine.

in most cases, according to the forecast to produce influenza vaccine can actually be better to match the season of flu strains, this vaccine protection is good. But now that is the forecast, will inevitably have deviation. This winter, the advantages of the epidemic in many regions is influenza b virus Yamagata, at the right moment is beyond the scope of the flu vaccine this year, so don’t, there is no vaccine for this type of protection.

After 48 hours but not to say that is completely useless. For severe patients, more than 48 hours after the onset time, can still benefit from antiviral treatment. But it was used to prevent, can’t replace the vaccine, only as a temporary emergency prevention measures, for without vaccination, or have not yet acquired immunity after vaccination of severe influenza high-risk groups. Last week, because our country individual medical institutions to inadequate preparation, in the face of the sudden arrival of the flu outbreak, various inventory of the cold virus drugs oseltamivir inventory clear.
