Researchers are exploring genetic forms of population control called gene drives that spread traits faster that happens naturally. The goal is to curb mosquito-borne diseases like malaria.
The mosquitoes that spread Japanese encephalitis are usually found in wetlands and drainage ditches, and will be out biting mostly at dawn and dusk.
Japanese encephalitis virus is rare and doesn't usually cause symptoms. But in a small proportion of cases it can result in long-term neurological impairment and death.
Warmer temperatures could lead to more zones of the country that make good breeding sites for mosquitoes.

Is our changing climate making regions of the US more suitable for ticks and mosquitoes that spread diseases? Or is the climate changing human physiology making us more vulnerable?
Climate change also has an impact on public health.
Scientists need to continue working across disciplines to find ways to disrupt disease transmission in the context of climate change.
More than 3.9 billion people live in regions where the Aedes aegypti mosquito is present. This species transmits Zika, dengue, chikungunya, and yellow fever.
For several billion people mosquitoes are more than a nuisance -- they transmit deadly diseases. Now genetic modification may prove the most effective defense against the mosquito, preventing disease.
Don’t scratch it!
Mosquitoes are picky about who they bite but it's not actually "us" that they're smelling when they choose their next meal...
Congolese health workers prepare equipment before the launch of vaccination campaign against the deadly Ebola virus.
A study of recent epidemics like Zika and Ebola suggests that the media may fail to tell the public what to do during an outbreak.
The tiny mosquito can be a big summer nuisance.
Mosquito abundance is linked to climate and weather, and global climate change may be helping spread these dangerous carriers of disease.

The collapse of Venezuela's public health system has terrible consequences inside the country, but it also is giving rise to mosquito-borne viruses that could spread to nearby countries.

The CDC recently announced an uptick in diseases spread by vectors such as mosquitoes and ticks. Here's why and what you can do to lower your risk.
At a construction site in New Delhi, workers are exposed to mosquito repellent.
The spread of infectious diseases such as chikungunya is closely linked to urban mobility, yet small Indian cities could play a crucial role in the resilience process.
Women's rights and poverty cannot be ignored.

Vast amounts of standing water in Houston and other hurricane-flooded areas are dangerous not only because of toxins. The water is a dangerous breeding ground for mosquitoes that transmit Zika.
Massive online DNA databases can be used as a resource to discover viruses -- even if the data had not been explicitly collected for that purpose.
Wondering why the Good Lord gave Culicoides impunctatus to Scotland? This might be the best answer yet.
Finding Zika’s roots can help contain the virus.
The 2015 Zika outbreak in South America brought the virus to global attention. But tracing the history of the virus in West Africa can give clues to tackling future outbreaks.

The first case of Zika in India was discovered in November 2016. Why was the public not informed about it?
When a man was diagnosed with Ebola in Dallas in 2014, workers cleared out the apartment unit where he had been staying.
President Trump wants to slash global health funding at a time when more investment is needed, not less. This spending can protect Americans – as well as foreigners – from deadly diseases.
