Gene drive guarantees that a trait will be passed to the next generation. But should society use this tool to control insect populations?
In 2018 scientists of the Miami-Dade County Mosquito Control tested a new way to suppress mosquito populations carrying the Zika virus.

Release of GM mosquitoes in Florida is imminent. But a multidisciplinary team of scientists believe that more studies are needed first. They encourage a publicly accessible registry for GM organisms.
The pangolin, one of the most poached animals in the world, could have served as an intermediate host in the transmission of SARS-CoV-2 to humans.
Covid-19, like other major epidemics, is not unrelated to the biodiversity and climate crisis we are experiencing.

The tremendous costs of COVID-19 show why the world needs to do a better job preventing epidemics from occurring – or at least mitigate the impact.

The declaration does not mean the risk to Canadians has changed, but it does mean Canada must step up to help those countries with weaker heath-care systems.
Although yellow fever does not currently exist in Australia, the species Aedes aegypti - which can transmit the disease - is found widely across northern Queensland. The virus remains a global health concern, but citizen scientists could help prevent its spread.
Nuisance-biting and mosquito-borne disease are ongoing concerns for health authorities. But an effective citizen science program is now showing how all of us can help beat the bite of mozzies.

There's a big market for new treatments for TB, malaria and other ailments. But most of these diseases afflict low-income people unable to pay for medicine.
Timing is everything when it comes to making a decision about declaring a disease outbreak a public health emergency of international concern.

In January, measles returned to the Pacific Northwest, while Ebola resurged in the Congo. It would take a lot more research for scientists to be able to stop threats like these in their tracks.

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.
