British couples should not try for a baby for a month if a partner has just returned from one of 23 countries affected by the Zika virus, public health officials have warned. Public Health England (PHE) said men should wear condoms for 28 days after coming home from countries like Brazil and Mexico if their partner was at risk of pregnancy, or already pregnant. Men who had suffered an unexplained fever while travelling, or who had been diagnosed with the virus, should avoid unprotected sex, or trying for children for six months. Woman have already been advised to avoid travelling to infected countries if they might be pregnant or are trying for a child. Around half a million people are believed to have travelled to Zika infected countries in the last six months, according to the most recent figures from the Office for National Statistics. The virus has already caused nearly 4,000 cases of malformed babies in the Americas and the World Health Organisation warned yesterday that the disease was spreading so quickly that four million people could be infected by the end of the year. Although the virus is mainly transmitted through mosquitoes, PHE said sexual transmission had been recorded in a ‘limited number of cases.’ Public Health England advised: “If a female partner is at risk of getting pregnant, or is already pregnant, condom use is advised for a male traveller for 28 days after his return from a Zika transmission area if he had no symptoms of unexplained fever and rash. “Condom use is advised for a male traveller for 6 months following recovery if a clinical illness compatible with Zika virus infection or laboratory confirmed Zika virus infection was reported.” Six Britons are already known to have picked up the disease through mosquito bites while travelling in Columbia, Suriname, Mexico, the Cook Islands and Guyana. Zika was first discovered in Africa in the 1940s but the first outbreak outside of Africa, Asia and the Pacific Islands only occurred last May, when a case was reported in Brazil. Since then the disease has spread to 22 other countries in south and central America and the Caribbean.
