The seriousness of an epidemic is a function of several factors, including the degree of contagiousness and potential for rapid spread.
A river flows through Nairobi’s Kibera slum. Communities should be engaged in environmental management to reduce mosquito breeding sites.
The country’s urban centres where unvaccinated people live in crowed settlements are key risk areas.
Disturbing the habitats of horseshoe bats, like these in Borneo, increases the risk of virus spillover.
How can nations prevent more pandemics like COVID-19? One priority is reducing the risk of diseases’ jumping from animals to humans. And that means understanding how human actions fuel that risk.
Protests against mandates and quarantines get the Founding Fathers’ ideas wrong.

Yellow fever, malaria and Ebola all spilled over from animals to humans at the edges of tropical forests. The new coronavirus is the latest zoonosis.
Vaccines are some of the most equitable and cost-effective health interventions available.
Coronavirus is a stark reminder of what a world without vaccines would look like.

Applied Epidemiological Modelling has enormous potential to improve how decisions are made about public health in African countries.
Countries can be better prepared and respond faster to disease outbreaks if public health data is shared more freely.
Sharing data openly across regions and organisations can help to accelerate preparedness and responses to public health emergencies.

Genetically modified mosquitoes breed fear and suspicion, especially since the research happens behind closed doors, away from the public. Now scientists and architects are trying to change that model.
The Nipah virus in India is just one example of a viral outbreak in 2018.
It doesn’t just seem like the world is experiencing more viral infections than before – it’s a reality. And the way humans live today helps viruses thrive.

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.
Africa is home to many disease outbreaks yet is ill-prepared to deal with them.
African leaders need to up their health allocations to help the new World Health Organisation Director-General meet his health care targets for the continent.

There’s a new weapon against mosquitoes that spreads diseases such as dengue and yellow fever – more mosquitoes.

Upscaling the success of emerging mosquito control technologies relies on automating the rearing and release of millions of mosquitoes. Australia is to become the testing ground for a novel strategy.
The outbreak of Zika virus in Brazil had Australian travellers on alert but transmission is only possible in tropical Queensland.
New research shows common local mosquitoes aren’t able to spread Zika. This means Australia is unlikely to see a major outbreak of the disease. But a risk remains in northern Queensland.
