NIH: Zika virus at "pandemic" level
NEW YORK — The World Health Organization warned Thursday the Zika virus is “spreading explosivelyâ€and could infect four million people by the end of the year.
It’s in 23 countries, including the U.S., where it is now being called a pandemic, with 31 cases in eleven states and D.C. since last year. All the patients here were infected by mosquitoes abroad.
The CDC has issued a travel alert advising pregnant women to postpone travel to nearly two dozen countries — mostly in Central and South America and the Caribbean — where Zika transmission is ongoing.
The virus, first discovered in the Zika Forest in Uganda in the 1940s, is linked to serious birth defects.

“If you have this much Zika in South America and the Caribbean, sooner or later we’re going to see a local transmission,†he said.
