The National Institute of Health has published its Boletín Epidemiológico for week 41. Here's my summary/translation of its Zika section:
From the start of the endemic phase in week 29 up through week 41, 3,645 Zika cases have been reported. This makes a total, since the start of the epidemic, of 8,826 confirmed cases and 95,898 suspected cases. The curve of report shows steady diminution since week 6 of 2016, apart from a brief increase in week 13. The average number of reports in the past five weeks was 133 cases/week.
Incidence of Zika during the epidemic phase was 376.2 cases per 100,000 urban resident. Post-epidemic, incidence is 13.7 per 100,000 urban residents. Women make up 66.3% of confirmed and suspected cases; 63.6% of cases were in persons aged 30-64; 2.8% were in babies under one year; 3.2% were in persons 65 and older.
Pregnant women diagnosed with Zika virus
From the start of the epidemic phase through week 41 of 2016, 5,881 cases have been confirmed in pregnant women; Zika is suspected in 13.223 women who reported symptoms compatible with Zika at some point in their pregnancy.
Intensified surveillance for microcephaly and other CNS congenital defects
Between weeks 1 and 41, 47 cases of Zika-associated microcephaly have been confirmed; 213 cases were discarded and 342 cases are under study.
Special surveillance for neurological syndromes with previous illness compatible with Zika virus infection
Since December 15, 2015, through week 41 of 2016, 642 cases of neurological syndromes have been reported after previous illness compatible with Zika virus. Men make up 55.6% (357) of these cases; 12.3% (79) are in persons 65 and older. Guillain-Barré syndrome made up 65.7%. The curve of such cases closely follows that of confirmed and suspected Zika cases.
