Microcephaly cases under investigation for links to Zika virus in Colombia keep accruing...

Diagnoses of Zika virus infection linked to microcephaly continue to very slowly rise in Colombia, rising by 11 since the end of July 2016 - with 1 new case in this most recent reporting week to reach a total of 47.[1] 

Brazil reports 2,033 cases of Zika virus congenital syndrome (CZVS) as of 20-OCT-2016, among a background of 109,596 "confirmed" cases.[2] However, a confirmed case listed by Brazil includes confirmed and probable cases as described by the Pan American Health Organization (PAHO) definition.[3]

Meanwhile the number of microcephaly (?CZVS or just head size?) cases that remain under investigation in Colombia continue to accumulate. 

Up until  mid-June, these numbers used to be in double digits, but they have risen dramatically (yellow dots in graph above) since then to reach over 300 and continue to climb steadily. How many of these will be added to the microcephaly/CZVS total is unclear.
