Brazil: Zika isn’t the only emergency. 2 other mosquito-borne viruses are spiking: Dengue and CHIKV. Meanwhile, the country is going through a massive economic and political crisis as well, facing one of the worst recessions in its history.
Thursday, April 7th, 2016Recife: “….New cases of microcephaly are dramatically down. Last November, Recife registered 125 cases. But since the beginning of this year, the numbers have hovered around 25 a month……[T]he decline was expected: Women giving birth this spring would have become pregnant during the cooler winter period when there were fewer mosquitoes around to transmit Zika……”

“…..The incidence of dengue hemorrhagic fever was less than 0.3 episodes per 100 person-years in each cohort. The percentage of VCD episodes requiring hospitalization was 19.1% in the Asian cohort and 11.1% in the Latin American cohort. In comparable age groups (9 to 12 years and 13 to 16 years), the burden of dengue was higher in Asia than in Latin America……”

Latest Research: Evidence suggests that symptomatic dengue during pregnancy might be associated with fetal adverse outcomes.
Sunday, March 6th, 2016** Preterm birth and low birth weight were the most common adverse outcomes in mothers who contracted dengue.
Colombia is said to have made progress on what could be an innovative way of controlling the disease. A tropical disease specialist at the University of Antioquia states scientists there had successfully bred a mosquito that was resistant to Zika, dengue, chikungunya and yellow fever.

“…..To create the strain, Dr. Vélez infected mosquitoes with bacteria that block the insects from picking up the virus. When the mosquitoes breed with ones that are susceptible to the disease, their progeny are shielded.
“The results are encouraging,” Dr. Vélez said, citing a recent pilot project near Medellín in which 80 percent of mosquitoes were rendered unable to transmit Zika…….”
