Zika Virus Cases Soar in Asia, WHO Says

Zika infections are expected to continue rising in the Asia-Pacific region, where authorities are increasing surveillance, preparing responses to complications and collaborating on information about the disease, the World Health Organization said Monday.

Complicating the fight against the virus, spread by mosquitoes, is the lack of a "foolproof" approach to mosquito control, as shown by decades of efforts to contain dengue virus, WHO Director General Margaret Chan said in her address to a Western Pacific regional meeting of the world health body.
