View of Aedes aegypti mosquitoes infected with the Wolbachia bacterium --which reduces mosquito transmitted diseases such as dengue and chikungunya by shortening adult lifespan, affect mosquito reproduction and interfere with pathogen replication-- at the Oswaldo Cruz foundation in Rio de Janeiro, Brazil, on October 2, 2014. The mosquitoes, when released, are expected to quickly infiltrate the insect population and stop the spread of the disease. Small-scale trials have already been conducted in communities in northern Australia.

Story highlights

Researchers first identified the Zika virus in 1947 after a fever developed in a rhesus monkey

Many scientists believe the 2007 strain of Zika has mutated from the original virus, with increased virulence

Zika Forest, Uganda CNN  — 

The turnoff into the Zika Forest is easy to miss, just a small break in the tree line along the main road between Entebbe Airport and Uganda’s capital, Kampala. A worn-out sign announcing its start only comes into view after a journey down a small dirt path.

The explosive spread of the Zika virus may have caught the world by surprise, but its namesake, the forest preserve near the edge of Lake Victoria, isn’t a place to just stumble on to. The researchers who have been coming here for more than a half-century come with a purpose: to study viruses and the mosquitoes that carry them.

Zika sexually transmitted in Texas, CDC confirms

A well-worn sign is the only indication of the start of the Zika forest, Uganda's only preserve devoted entirely to science research.
