Next week the U.N. health agency will convene a Zika emergency committee to assess the latest status of the virus, which can cause brain damage in newborns and paralysis in adults. The Zika virus is now in 60 countries, with Olympic host Brazil the hardest-hit nation.

WHO Director-General Dr. Margaret Chan has asked committee members to examine the risks of holding the Olympic Games, which run Aug. 5-21.
