Puerto Rico has confirmed its first case of Zika virus, a mosquito-borne virus carried by the same species as dengue and chikungunya, though the source has yet to be identified, according to the Centers for Disease Control and Prevention, UPI reported. The virus was identified in the Zika forest in Uganda in 1947 and is spread when mosquitoes bite an infected person. Outbreaks of Zika virus have happened in Africa, Southeast Asia, and the Pacific Island, and the virus has been reported in the Americas in recent years. There is no vaccine or medicine to treat infection.
