World Health Organisation says there is no proven link of Zika virus infection and Microcephaly but there is a reason for the concern. Earlier this month, the U.S. Center for Disease Control and Prevention warned pregnant women to avoid travel to 14 countries and territories in Latin America and the Caribbean affected by the virus. A Danish man who returned from a trip to Mexico and Brazil has tested positive, the first case confirmed in Europe. Three Britons who traveled to South America have also been infected. The World Health Organisation (WHO) has warned that the mosquito-borne Zika virus could spread to almost every country in the Americas. For the instant there is no vaccine or cure. An increased occurrence of neurological symptoms was suggested.
