Blood tests reveal broad extent of Zika infection

A new study shows that nearly half of the population of Managua, Nicaragua, has been infected with the Zika virus. Previous infection with the Zika virus imparts immunity to the disease and can help quell future outbreaks.

Study details how dengue infection hits harder second time around

One of the most vexing challenges in the battle against dengue virus, a potentially fatal mosquito-borne virus, is that getting infected once can put people at greater risk for a more severe infection down the road. A new study with UC Berkeley researchers details how the interaction between a person’s immune response and a subsequent dengue infection could mean the difference between getting a mild fever and going into a fatal circulatory failure.

Pre-exposure to the dengue virus seems to protect children from harmful symptoms when they're subsequently infected by the Zika virus, a study co-led by public health professor Eva Harris has found. The researchers analyzed data from the large 2016 Zika epidemic in Nicaragua, focusing on a pediatric cohort with a history of exposure to the dengue virus. The cohort was established in 2004 to study dengue infections, and it includes some 3,700 children aged two to 14 years old. The findings support the hypothesis that there is an immunological interaction between the two viruses, which are transmitted by the same mosquito and affect the same populations.
