A technology based on chemical analyses by infrared rays capable of speeding the monitoring of the presence of zika in Aedes aegypti mosquitoes by 18 times and of cheapening it by 116 times. This is the new bet of researchers from the Oswaldo Cruz Institute (IOC/Fiocruz) to improve the surveillance of virus circulation. Known as 'near-infrared spectroscopy', the technique is simple, has a high accuracy rate and requires no use of...

In Brazil, a mother is as vulnerable as her child born with microcephaly due to zika in the last three years, as well as the other women involved in this child daily care. With a systematic routine of doctor’s appointments, stimulation and recovery activities for the child, they had to stop working - which impacts family income - abandon personal projects and face the difficulties of a health system unprepared to care for their children....

The zika virus was already circulating in Brazil in the first quarter of 2014, more than one year before infection cases were detected in the country, according to new data from an international study, revealed in Nature, conducted by Fiocruz researchers in partnership with the Broad Institute and institutions of several countries. The research also revealed that Brazil was the source of the outbreak in the Americas.

What is the situation of the families of children affected by zika virus more than two years after the epidemic in Brazil? What social dimensions of the disease were ignored, and how to remove them from invisibility? How is discussion about the virus inseparable from a debate on women's reproductive rights and abortion, for example? What should be an ethical approach for research subjects with such a sensitive subject matter?

A study conducted by Fiocruz Pernambuco reveals how zika virus got to Brazil, filling a gap in the literature addressing this topic. Among the most frequent hypotheses, the virus was believed to have been introduced in Brazil during the 2014 World Cup (June 12th to July 13th), brought by African travelers. Another theory said the virus had been introduced during the world canoeing championship held in August 2014, in Rio de Janeiro, that...
