Jammuties planning a visit to Amercias particularly Latin America, and Carribean islands should avoid visiting these countries because the dangerous Zika virus is spreading very fast there. At least 4 million people could be infected by Zika by the end of this year, and the outbreak could spread to other parts of the world. The WHO has particularly warned pregnant women to refrain from visiting these countries as the virus could lead unusually small heads and brain damage to new borns.
Some pregnant women from US, and Europe who have been to these countries are likely to be tested for Zika virus. The Zika virus is a mosquito borne disease which was first observed in Zika forest in Uganda in 1947. It is common in Africa, and Asia but had not spread so widely earlier. It is relayed to dengue, yellow fever, and west nile virus.
As there very few people who have immune defence against this virus millions are likely to be infected, and several millions already infected in the American countries. For most the virus may not cause harm but for pregnant women it could be dangerous for the newborns.
