NEW YORK (AP) — New York City health officials say three New Yorkers have contracted the Zika virus.
All three had recently returned from countries that have experienced a Zika outbreak.
The virus is believed to spread to people through the bites of infected mosquitoes.
Most people do not need to be hospitalized from the disease. But officials are studying whether some severe birth defects can be linked to an infection during pregnancy.
Officials said one of the sickened New Yorkers is pregnant.
The disease is not believed to spread via human contact and the mosquitoes believed to carry it are not found in New York.
Zika has been found in Africa, Latin America and the Caribbean. Health officials declined to say from where the infected New Yorkers had traveled.
