Over 3,100 pregnant Colombian women are infected with the mosquito-borne Zika virus, President Juan Manuel Santos says.
The mosquito behind the Zika virus seems to operate like a heat-driven missile of disease. The hotter it gets, the better the mosquito that carries Zika virus is at transmitting its buffet of dangerous illnesses, scientists say.
Densely packed slums, rampant mosquitoes and a history of rapidly spreading infections make Asia particularly vulnerable to the devastating Zika virus, posing a massive challenge for the region, health experts warn.
The World Health Organization sets up a Zika "emergency team" after the "explosive" spread of the virus.
The Brazilian health ministry has confirmed a link between a mosquito-borne virus from Africa, Zika Fever, and a high incidence of birth defects.
