US Health Experts Confirm Microcephaly Link With Zika Virus

After several weeks of study and debate, US health officials concluded that being infected with the Zika virus during pregnancy causes the birth defect microcephaly, a finding that experts hope will refocus attention on efforts to stop infections and prompt US lawmakers to fund emergency prevention efforts.There isn’t any doubt that Zika causes microcephaly. Dr Tom Frieden, Director, US Centres for Disease Control and Prevention (CDC)US and world health officials have been saying for weeks that mounting scientific evidence points to the mosquito-borne virus as the likely cause of the alarming rise in microcephaly in Zika-hit areas of Brazil. It had not been declared as the definitive cause until now.The announcement comes at a critical time for the Obama administration, which has been urging the Republican-controlled Congress to grant nearly $1.9 billion in emergency funds to fight the virus, which is already affecting Puerto Rico and is expected to hit parts of the United States with the coming of mosquito-friendly warmer weather. In a temporary fix, the White House said last week that it would redirect $589 million in allocated funds to prepare for Zika‘s arrival in the continental United States.The declaration of Zika as a cause of microcephaly may make it harder for lawmakers to deny the request for emergency funding.“I think it’s a game-changer,” said Dr Lawrence Gostin, a global health law expert at Georgetown University who testified before Congress last month on the need for Zika funding.It’s acceptable if we don’t know for sure if a risk is going to emerge and we’re unprepared, but it’s shameful if we absolutely know that an epidemic is coming and we fail to prepare.Dr Lawrence Gostin, Global Health Law ExpertIn February, the World Health Organization declared Zika a global health emergency based on its suspected link to thousands of cases in Brazil of microcephaly, a birth defect marked by small head size and underdeveloped brains.The declaration kicked off a flurry of studies to prove a link. The CDC said its latest conclusions came after all necessary scientific criteria had been met to make the official call.The data are there. The evidence is there. The pieces of information we have now makes us confident. Dr Sonja Rasmussen, Director - Public Health Information, CDCCDC now believes microcephaly is just one of a range of serious birth defects caused by Zika.In Brazil, officials have confirmed more than 1,100 cases of microcephaly and considers most of them to be related to Zika infections in the mothers. It is investigating more than 3,800 additional suspected cases.CDC travel and sexual transmission guidelines remain unchanged. Women who are pregnant or planning to become pregnant are advised to avoid travel to the at least 42 countries and territories where Zika has spread, and men who have been to those areas are advised to abstain from sex or use condoms with partners who are pregnant or trying to become pregnant.
