Brazil MOH: Epi Week 6 Microcephaly report

# 11,029

The Brazilian MOH released an updated report card on their Microcephaly investigation yesterday, adding 201 additional suspected cases, while confirming 46 and discarding 72 from the backlog of more than 3,800 suspected cases previously under scrutiny.

Out of the 1345 cases already investigated, 508 (37.8%) have been confirmed as microcephalic by Brazilian authorities. Nearly 4,000 suspected cases remain under investigation.

So far Brazil is the only country in the Americas reporting elevated microcephalic births, which has tentatively been linked to maternal Zika virus infection.  While the numbers were much smaller, we did see similar reports from French Polynesia's outbreak in 2013-2014.

There are reportedly as many as 5,000 Colombian women, pregnant and exposed to the Zika virus, who will probably begin giving birth in May and June.  Assuming the Zika link is true, we should begin to see elevated microcephalic births in Colombia over the summer.
