A new map shows mosquitoes that can carry the Zika virus can be found in 40 states and Washington, D.C., NBC News reported.
Experts from the Centers for Disease Control and Prevention compiled the new map by looking at all reports of the two species of mosquito that can transmit the virus: the yellow fever mosquito and the Asian tiger mosquito.
Public health officials are bracing for local Zika outbreaks across the continental U.S., where 618 cases have already been documented. Thousands of infected people have traveled from Latin America and the Caribbean — and if a mosquito bites someone with an active investigation, it could carry the virus to someone else.
President Barack Obama asked Congress for $.9 billion to fight Zika. The House and Senate are considering separate bills to provide some of the money.
