The National Institute of Health has published its Boletín Epidemiologico for week 29; the Zika section starts on page 101. Here's my summary/translation of some key Zika facts and numbers:
Since the start of the epidemic in week 40 of 2015, 8,826 Zika cases have been confirmed as well as 91,640 clinically suspect cases.Week 29 saw 745 cases, 368 new this week and 377 delayed reports from earlier weeks. All 745 cases were suspected. The departments of Valle del Cauca, Norte Santander, Santander, Tolima, and Huila account for 57.46% of all reported cases.
The curve of reports has been diminishing since week 6 of 2016; the most cases reported to the surveillance system was 6,307 in week 5. The average number of cases reported in the past weeks is 841/week. Women make up 66.08% of confirmed and suspected cases. Adults aged 30-64 make up 63.57%; 14.08% are aged 25-29; babies under one year make up 2.63% and those older than 65 are 3.25%.
Pregnant women diagnosed with Zika virus
From the start of the epidemic to week 29, 6,058 cases have been confirmed in pregnant women and suspected in 11,962. Valle del Cauca has the highest proportion of such cases, 2,729 (15.14%).
Intensified surveillance for microcephaly
Between weeks 1 and 29, 21 cases of Zika-related microcephaly have been confirmed, 92 cases were discarded, and 207 remain under study.
Special surveillance for neurological syndromes
Between December 15, 2015 and week 29, 608 cases of neurological syndrome have been reported with prior symptoms of Zika virus; all are under verification. Norte Santander, with 82 cases (13.49%), has the highest proportion of such cases. Men made up 47.1% of cases (347); persons over age 65 are 11.8% (72). Guillain-Barré syndrome made up 408 cases (67.1%) The curve of reports is compatible with that of Zika cases in Colombia.
