The National Institute of Health has published its Boletín Epidemiológico for week 30. Here's my summary/translation of its Zika section, which begins on page 104:
From the start of the epidemic in week 40 of 2015 up through week 30 of 2016, 8,826 Zika cases have been confirmed and 92,319 are clinically suspected. In week 30, 679 cases were reported—352 new this week and 327 delayed reports from earlier weeks. The departments of Valle del Cauca, Norte Santander, Santander, Tolima, and Huila accounted for 57.58% of all cases.
The curve of reports has been diminishing since week 6 of 2016, apart from an increase in week 13. The surveillance system saw the most cases (6,312) in week 5. The average over the past five weeks is 703 cases/week. Women make up 66.1% of cases. Adults aged 30 to 64 make up 63.57% of cases; 14.09% are aged 25 to 29; 266% are babies under one year; 3.24% are adult 65 and older.
Pregnant women diagnosed with Zika virus
From the start of the epidemic through week 29 of 2016, 6,057 cases have been confirmed in pregnant women, and 12,091 suspected cases in women who had Zika-compatible symptoms at some point in their pregnancy. Valle del Cauca has the highest concentration, with 2,798 (15.42%).
Intensified surveillance for microcephaly
Between weeks 1 and 30 of 2016, 22 cases of Zika-associated microcephaly have been confirmed, 97 were discarded, and 225 cases are under study.
Special surveillance for neurological syndromes
Between December 15, 2015, and week 30, 617 neurological-syndrome cases have been reported with Zika-compatible symptoms. All are being verified, so the numbers may change. Norte Santander with 82 cases (13.29%) has the highest proportion. Men make up 57.1% (352) of cases involving neurological syndromes, and 73 (11.8%) are in persons aged 65 or older.
Cases of Guillain-Barré syndrome make up 66.12% of neurological syndrome cases (408). The curve of reports follows that of confirmed and suspected Zika cases.
