Is the Virus H1N1 dependent of the cold climates or cold ambients ecosystem?

Maybe in chile the virus H1N1, it has been very aggressive and someone people have died, some victim they are residents in a southern of Chile, in that region the temperatures are low and possess cold range. In the other hand in chile the season is winter. In Africa until the moment any case of virus H1N1 has not been reported in Africa,and in other country that have warm climates, is necessary to think that in Africa the climate is temeperate, it’s the temperate climate on factor that determine the falling the curve of population the virus H1N1?. Thank you for your question.

That’s interesting, Aleiandro. I know little about this topic but I have read this week that the Inuit populations are proving particularly susceptible too. Apparently the Inuit were also susceptible to the 1918 flu too. I’d thought on reading the report that the implication was that it was a genetic susceptibility – but temperature could presumably be a factor too.
However I also remember reading somewhere a couple of months ago that it was thought that the virus might not survive as well in colder places. Mexico, after all, is close to the tropics, and at that stage the virus seemed to be not as lethal in temperate places like USA and the Europe. This is the opposite to what you’re saying, of course – and opposite to the Inuit observation too.

I always thought that the effect was increased transmission in cold climates; more people in close proximity to keep warm results in more efficient spread of the virus. Therefore more deaths may just reflect more (undetected) cases.

Just found it! The Inuit connection with Swine Flu was mentioned here – in Nature’s recent Swine Flu round up.
-
And apologies – it was Bird Flu that was thought to be unlikely to survive outside the Tropics. There’s a paper here.

Thank you Clare I will inform and go read this paper’s.

I read this paper’s Clare, and think that the cold temperature of environmental is favorable for the populational development of the pandemic virus of the H1N1 swine flu. Maybe the cold stimulate the transmission the virus very fast at the near guest, at near distances. Is very important count this factor of operating temperature when determining an action of destroying the virus. This is what I think. Thank for your attention.
Best wishes.

Once again, the virus swin flu causes in southern Chile 40 ° 33’S, 73 ° 07 ’, where climates are cool and rainfall is high, it will be a factor to be taken into account when assessing the aggressiveness of the virus?.
Best wishes,

cause a new victim in Chile.

My friends, there is a seventh victim in southern Chile by swuin flu pandemic virus. The victim lived in Chiloe in southern Chile. My question is whether the low temperatures will be a biotic factor determined to turn any gene of DNA segments, that produces a higher aggressiveness by the flu pandemic virus swuin?. or simply the rate of mutation of the virus reverts to biotic factors favorable to their development?
I hope you respond, Thank you.
Sincerely,
Yours, Alejandro Correa

There are twelve victims produced for the swine flu in southern Chile that there is a greater number of victims. I wonder if the H1N1 virus will have mutated, which behaves more aggressively, due to environment or other factors not elucidated, it seems at least strange?. I called subtype H1N1P, ¿what are you think?. Maybe it is advisable to vaccinate the population of adults with human flu vaccines related subtypes (eg type A), since in general has caused casualties, it is assumed that the virus has a genetic map similar to the other subtypes. On the other hand I think it should be blocking the receptor cells of sialic acid by blocking the hemagglutinin of the virus protein capsule. Just a suggestion.
