One way to discover drugs is by drug repurposing, which is the process of discovering "new" drugs from "old" ones. Instead of starting from scratch (which takes 10+ years), if scientists can find an approved drug that treats a different -- often untreatable -- condition, considerable time and cost can be saved. In this manner, a drug that cures hepatitis C was found be effective against Yellow Fever and Chikungunya. Does this make sense?
Researchers have been able to identify a gene that determines maleness in mosquitoes, and if that were introduced into females it could potentially help wipe out the vector for the Zika virus infection. This method could also be applied to fighting other diseases such as yellow fever, Dengue and Chikungunya.
The FDA and CDC are expressing concerns about the potential for rising rates of transfusion-associated infections, with both agencies calling for more testing and precautions. Cash-strapped blood banks are not nearly so concerned.
Dengue and chikungunya are both viruses spread by a species of mosquito known as Aedes aegypti. Dengue sickens 50 million people worldwide and chikungunya infected

Chikungunya is the latest virus you probably have never heard of. Carried by a couple of species of mosquito (both of which are found in the United States) and first described in Africa in 1952, the virus causes an abrupt onset of fever and severe joint pain (arthralgia) that may become chronic. Since that time, chikungunya has been found to be widespread in both Africa and Asia, and has now spread to the Caribbean islands and a few states in the U.S.
