Link Between Zika and Microcephaly to be Studied

  • Brazil’s health minister, Marcelo Castro, says he is “absolutely sure” mosquito-borne Zika is responsible for a spike in cases of the rare birth defect microcephaly.
  • But with scant scientific literature published on the matter, some doctors in Brazil and elsewhere say there is not yet enough scientific data to prove the connection.
  • Joint teams of U.S. and Brazilian health workers will conduct a study to determine whether the Zika virus is causing babies to be born with unusually small heads.
