dengue fever

Brazil looks to short-term and long-term strategies to fight a disease so painful it's known as "breakbone fever." The outbreak is part of a global wave of dengue triggered in part by climate change.

Scientists say gene-editing technology may eradicate a mosquito in the U.S. that spreads dengue and other diseases. Concerns remain about the possible environmental impact of bioengineered mosquitoes.

The number of patients is soaring, the health system is stressed and the government is facing criticism over its response. So far 150,000 Peruvians have caught the virus this year and 248 have died.

It took 20 years and $1.5 billion to develop a vaccine for dengue, a deadly mosquito-borne virus. After it finally got approval in many countries, a complication has surfaced.

Brazil has long faced outbreaks of dengue fever. But Acre State was immune — until very recently. Now there's a possible explanation.

Scientists have long sought a way to fight mosquito-borne viruses without pesticides. For researchers like Scott O'Neill, the Wolbachia bacteria offered that chance. But they had to prove it.

A dengue fever outbreak has left some hospitals so full that they're turning away patients.
