Rainfall can indicate that mosquito-borne epidemics will occur weeks later
FINDINGSA new study demonstrates that outbreaks of mosquito-borne viruses Zika and Chikungunya generally occur about three weeks after heavy rainfall.Researchers also found that Chikungunya will predominate over Zika when both circulate at the same time, because Chikungunya has a shorter incubation period — just two days, versus 10 days for Zika. The latter finding explains why a late-2015 Zika epidemic in Rio de Janeiro ended while the number of Chikungunya cases increased in February 2016.BACKGROUNDViruses transmitted by insects can lead to serious health repercussions. Zika is linked to birth defects, and up to 1 ...

Antibody-dependent enhancement of severe dengue disease in humans
For dengue viruses 1 to 4 (DENV1-4), a specific range of antibody titer has been shown to enhance viral replication in vitro and severe disease in animal models. Although suspected, such antibody-dependent enhancement of severe disease has not been shown to occur in humans. Using multiple statistical approaches to study a long-term pediatric cohort in Nicaragua, we show that risk of severe dengue disease is highest within a narrow range of preexisting anti-DENV antibody titers. By contrast, we observe protection from all symptomatic dengue disease at high antibody titers. Thus, immune correlates of severe dengue must be ev...

Dengue immunity can protect against Zika virus
(La Jolla Institute for Allergy and Immunology) A study published the Nov. 13, 2017, issue of Nature Communications by La Jolla Institute for Allergy and Immunology (LJI) investigator Sujan Shresta, Ph.D., now addresses interplay between dengue and ZIKV infections. It reports that mice rendered immune to dengue show 'cross-protection' from subsequent Zika infection and then identifies specific types of immune T-cells capable of defending against both viruses. These revelations have profound implications for efforts to build a potent anti-Zika vaccine. (Source: EurekAlert! - Medicine and Health)
