The mosquito-borne Zika virus is spreading across the Americas and Europe and will continue to spread in Africa.
The number of confirmed cases in the Americas rose by nearly 300% from the beginning of the year, according to a new report from the World Health Organization.
The virus also is spreading in Mexico, Central America, South America, Australia, New Zealand and parts of Asia.
The World Health Organization says that since the beginning for Zika in the U.S. on March 6, at least 10 people have been diagnosed with the virus.
The WHO says the virus has not been isolated in Mexico or Central America and has not shown itself in South America.
In the U., the latest cases were reported in California, Georgia, Maryland, Minnesota, New York, Ohio, Pennsylvania, Rhode Island and Washington, D.C.
The CDC reported Tuesday that an additional 3,200 cases were confirmed across the U, with an additional 7,400 cases confirmed.
