Madrid, February 2 (RHC)-- Officials say laboratory tests have confirmed a fourth case Zika virus in Spain. The southeastern regional government of Murcia said Tuesday that tests carried out by the National Microbiology Center confirmed the case of a man treated two weeks ago at a regional hospital after visiting an unspecified country affected by the virus.

The man, who was not identified but was said to be middle-aged and a Spanish resident, has been given the all clear after been treated for the virus and to avoid contagion. The other three cases in Spain also concerned people who had traveled to affected regions in Latin America.

The World Health Organization is recommending that visitors and residents in affected areas, especially pregnant women, take measures to avoid being bitten by mosquitoes that transmit the virus.
