Zika virus linked to birth defects is international emergency, WHO says
None
The World Health Organization has declared the mosquito-borne Zika virus to be an international public health emergency due to its link to thousands of suspected cases of birth defects in Brazil.
WHO Director-General Margaret Chan told reporters on Monday coordinated international action was needed to improve detection and speed work on a vaccine and better diagnostics for the disease, although curbs on travel or trade were not necessary.
