State health officials said on Friday that three people in New York State, including one from Queens, tested positive for Zika, a mosquito-borne virus that has prompted concern as it has spread rapidly, mostly in Latin America and the Caribbean.

All three had traveled to places outside the United States where the virus had been spreading. Besides the person from New York City, the patients were from Nassau and Orange Counties. One person has fully recovered, and the two others are recovering without complications, according to a statement the State Health Department issued on Friday.

Health officials said the virus’s symptoms — including fever, rash, joint pain and red eyes — are typically mild and last up to a week. Some may not even realize they have been infected. About one in five people who have been bitten by an infected mosquito will grow ill, with symptoms usually appearing within a few days.
