CDC issues report on Brazil's outbreak of mosquito-borne illnesses
Brazil’s health authorities report that mosquito-borne viruses, including dengue, chikungunya and the zika virus, have been seen in the country in clusters since the latter part of 2014. They also report that the zika virus began to appear in April of 2015.
Salvador, a large city in Brazil, has reported 14,835 cases of indeterminate illness that were exanthematous — referring to a skin eruption or rash — in 12 districts. Diseases that fit under this category include dengue fever, chikungunya and zika.
The CDC reports that the peak of cases occurred in the first part of May, following the discovery of eight positive cases of the zika virus.
These three viruses are commonly spread through to mosquito species that are common in Brazil. The CDC states that the spread of zika presents additional challenges to the health system due to the transmission of related diseases from the same source. This report indicates that the three viruses have the potential to become a severe outbreak situation in the Western Hemisphere.
