The Brazilian MOH has published their latest weekly surveillance report on suspected and confirmed microcephalic births, adding more than 600 suspected cases over the past week.  This represents the largest one-week increase in suspected cases we've seen to date.  

The net-under-investigation number only increases by 212 over last week since another 134 confirmed cases and 247 discarded cases were deducted from this week's total. 

So far, of those cases fully investigated, roughly 1/3rd have been confirmed (404 of 1113) as microcephalic. While the true number of microcephalic births in Brazil prior to 2015 remains a subject of debate (see Pondering The Great Zika Unknowns), this nonetheless appears to be a substantial increase.
