CDC Links Zika Virus to Microcephaly, Other Birth Defects

Why it matters locally: South Carolina's Department of Health and Environmental Control (DHEC) has been actively monitoring and preparing for potential Zika cases due to the state's climate and mosquito population, making this conclusive link a critical factor in ongoing public health strategies and resource allocation.

Atlanta — The Centers for Disease Control and Prevention (CDC) has determined that the Zika virus causes microcephaly and other severe brain defects in developing fetuses. The agency announced its conclusion following a comprehensive review of existing scientific evidence. According to the CDC, the determination marks a shift in scientific understanding of the virus. Previously, the Zika virus was suspected of having a connection to these conditions, but now the CDC asserts a definitive causal relationship. Microcephaly is a condition where a baby's head is significantly smaller than expected, often indicating incomplete brain development. The agency noted that the link extends to "other severe fetal brain defects", without elaborating on specific examples. CDC officials did not specify the precise data or studies that led to the agency's determination in the released statement. Additional information is expected to be released outlining the evidentiary basis for the conclusion.
