Scientists around the world investigate how bat immune systems cope with viral attacks and how this information could be used to keep humans safe.

Scientists find first 5' promoter element in dengue genome, perhaps explaining why virus loops before being copied

Researchers report evidence of antibody-dependent enhancement in a Zika-infected, immunocompromised mouse model.

Flavivirus infections alter the skin microbiome of mice to increase the production of a sweet-smelling compound that attracts the viruses’ insect vectors, a study finds.

The drugs’ disruption of the microbiome makes a subsequent flavivirus infection more severe.

Studies in mice suggest that other flaviviruses, such as West Nile virus and Powassan virus, may cause birth defects, too. 

A detailed structure of the pathogen highlights its similarities to—and one major difference from—other flaviviruses. 

Previous flavivirus infection could help explain the severity of symptoms in some people infected during the ongoing Zika outbreak, researchers report.

By avoiding the production of antibodies, something vaccines ordinarily induce, the immunization sidesteps the problem of antibody-dependent enhancement, which can amplify infection by a similar virus and is known to occur with dengue and Zika.

A study of Nicaraguan children links prior Zika virus infection with aggravated dengue fever symptoms.
