Plotting the Brazil microcephaly data...

These graphs are made using data obtained from Week 13's Brazil Ministry of Health microcephaly report, which you can also find here.

The chart above reports the second quietest week of 2016 in terms of the number of newly suspected microcephaly cases in Brazil up to 02-April-2016.

In the second graph, we can see a steeper rise in suspected microcephaly diagnoses that were discarded as being not microcephaly - the biggest since these microcephaly reports began. This rise was greater than the rise in confirmed microcephaly diagnoses - which was the 5th biggest rise since reporting began. 

Zika virus (ZIKV) detections jumped by the largest weekly amount (up by 40) since the Brazilian reports began noting laboratory confirmed detections in these reports. 

Also the biggest change, and not plotted here, was a drop of 245 cases under investigation, down from 4291 last week, to 4046 this week.  The second consecutive week seeing a negative adjustment.

There is still no sign of ZIKV testing in a more general sense from Brazil - just these numbers in the context of microcephaly. We rely in Colombia to get a sense of how many overall suspect cases are confirmed as ZIKV positive.
