Concerns for global spread of Zika mean Rio de Janeiro Olympics must not proceed
What will prevent the outbreak is the weather in Rio. The Zika mosquito takes 3 to 4 weeks to reproduce <a href="http://www.denguevirusnet.com/life-cycle-of-aedes-aegypti.html" rel="nofollow">http://www.denguevirusnet.com/life-cycle-of-aedes-aegypti.ht...</a>
and it loves hot and wet weather.<p>The autumn in Rio is the coldest and driest in a long time <a href="http://g1.globo.com/rio-de-janeiro/noticia/2016/03/outono-no-rio-sera-mais-frio-e-tera-menos-chuvas-esse-ano.html" rel="nofollow">http://g1.globo.com/rio-de-janeiro/noticia/2016/03/outono-no...</a>
When the Olympics arrive, the mosquito will be in their lowest population count.<p>If you consider that the Olympics tourists are rich ones, that will spend most of their times in air conditioned environments, the risk is really very low.
