The number of travel-related Zika cases in Arizona rose to three after two new cases were reported, the Arizona Department of Health Service said in a tweet.

No other details about the new cases were released.

The first case of Zika in Arizona was announced on March 28.

The virus is spread mainly through the bite of a tropical mosquito called Aedes aegypti. It can be found in the southern United States, but there's no evidence that they've been spreading the virus in the U.S. yet. All the 544 total cases in the 50 states so far have been people who had traveled to outbreak areas, or who had sex with someone who did.

Experts think mosquitoes on the U.S. mainland will probably start spreading the virus in the months ahead, when hot weather hits and mosquito populations boom.

The Zika virus causes only a mild and brief illness, at worst, in most people. But in the last year, infections in pregnant women have been strongly linked to fetal deaths and to potentially devastating birth defects, mostly in Brazil.

There are now 157 pregnant women infected with Zika in the 50 states, up from the 48 reported last week under the old definition.

President Barack Obama was briefed Friday by top federal health officials about Zika. Administration officials have asked Congress for about $1.9 billion in emergency funding for vaccine development and other Zika work.
