Everyone loves warm weather, but is it more deadly?
A blog post from Oh, For The Love Of Science! talks about the West Nile virus. This is a very dangerous disease that was first seen in the United States in 1999, which is said to have been the hottest and driest year in history. A slight increase in temperature, as little as 2 degrees, can greatly increase the spread of this disease. Higher temperatures can magnify the infections of this disease, there is a shorter time period from when the infection occurs and symptoms appear. Higher temperatures also increase the survival rate of the virus. So the prediction from this article is that "as our climate changes, more mosquitoes will be able to infect more people, more quickly and in more places."
