Fear of More Dangerous Second Zika, Dengue Infections Unfounded in Monkeys

An initial infection with dengue virus did not prime monkeys for an especially virulent infection of Zika virus, according to a new study. Nor did a bout with Zika make a follow-on dengue infection ...

Scientists Uncover Mechanism Behind Development of Viral Infections

A team of researchers found that immune cells undergoing stress and an altered metabolism are the reasons why some individuals become sick from viral infections while others do not, when exposed to ...

Combating Mosquito-Borne Diseases With Bacteria

Viruses, spread through mosquito bites, cause human illnesses such as dengue fever, Zika and yellow fever. A new control technique harnesses a naturally occurring bacterium called Wolbachia that ...

Mosquito Control Program Reduces Dengue, Costs in Sri Lanka

A public health, police, and military partnership to reduce the mosquito population in Sri Lanka resulted in a more than 50% reduction in dengue, as well as cost savings, finds a new ...

Shedding Light on the Burden of Dengue in Bangladesh
