The Centers for Disease Control and Prevention (CDC) has confirmed the presence of the Zika virus in two Brazilian babies who died of microcephaly, according to USA Today. CDC Director Tom Frieden, M.D., stressed to the House Foreign Affairs Committee that this did not definitely prove causation and called for further tests. "Zika is new, and new diseases can be scary, particularly when they can affect the most vulnerable among us," Frieden said. He reiterated the CDC's assurances that the virus is not a major threat to non-pregnant women, adding that 8 in 10 Zika patients will not manifest any symptoms. Article
