Than the swine flu differs from the seasonal?

The virus of swine flu has the same formula, as well as virus usual АH1N1, but differs from it that contains genetic material from 3 viruses – swine, bird's and human.

Why it calls trouble physicians? Any flu – disease seasonal. Usually we are ill with flu in cold season: in second half of autumn, in the winter, in the beginning of spring. In the summer this virus of diseases doesn't call (we speak about our Northern hemisphere) though circulates within all year. And here swine flu people have started to be ill in the spring. The first cases have been registered in Mexico and the USA. In the summer illness has started to creep away on other countries. That the virus actively circulates in warm season, – one of pandemic signs. Flu pandemics were already observed in the XX-th century: 1918 year – the Spaniard, 1958 – the Asian flu, 1968 – Hong Kong … And in all these cases the first wave was spring-and-summer, the same as and at pork flu. Therefore there are fears that in the autumn and in the winter in epidemic will be involved more and more people.
Than it is dangerous?

Whether to thicket the pork flu leads to lethal outcome, than seasonal, to tell difficultly. In the different countries – different lines of thought to calculation of losses.

In the world already has died more than 1 % ill with swine flu, 4,5 thousand people – considerable loss.

There are two more features of this infection:

it more often, than the seasonal flu, gives complications in the form of pneumonia;
with swine flu are ill youth and people of able-bodied age is more often, and here elderly have appeared are subject to new disease less. Probably, the similar virus already circulated on planet, and at older persons the immune system remembers meeting with it.
