People should minimise contact with birds in areas affected by bird flu viruses, including farms and settings where live animals may be sold or slaughtered.
Bird flu is decimating species already threatened by climate change and habitat loss.
A disfiguring disease of cattle and buffalo has arrived on our doorstep. We need to keep lumpy skin disease out of Australia, while preparing for the almost inevitable outbreak.
Alaskapox was discovered in 2015 and has generally only caused mild illness – until now.
Your mouth and your gut is full of them. But we don’t know if they’re friend or foe.
The JN.1 variant has become dominant in Australia and around the world, causing large waves of infections. Here’s what we know about it so far – and why it’s so important.
The current triple epidemic of respiratory viruses is affecting all age groups, prompting comparisons with the pre-COVID-19 era.
We tend to just think of viruses in terms of their damaging impacts on human health and lives. But viruses can also be used to benefit human health, agriculture and the environment.
We’ve all heard of antibiotic resistance. The same thing is happening with other causes of infections in humans: fungi, viruses and parasites. This is making thrush and other infections hard to treat.
Viruses can get into cells in several ways. Figuring out how to stop them from entering in the first place is a key to developing better vaccines and stopping future pandemics.
Researchers discovered a satellite virus latching onto the neck of another virus called MindFlayer. Studying the viral arms race between similar viruses could lead to new ways to fight infections.
The Sahel region is grappling with an outbreak of the deadly mosquito-borne disease.
New and innovative thinking is needed to deal with the reality on the ground in South Africa.
The human body has been making antivirals for eons, long before scientists did. A protein in your cells called viperin produces molecules that work similarly to the COVID-19 antiviral remdesivir.
It can be difficult to an appointment to see your GP. So when should you make the effort to see a GP for a prescription for influenza antivirals? And how effective are they?
Health workers who picked their noses were more likely to contract COVID, according to a new study. But here’s what the study means for the rest of us.
COVID, the flu and RSV spread from person to person through respiratory droplets when someone coughs, sneezes or talks. Here’s how our body fights them off.
Researchers simulated thousands of scenarios of an ancient pathogen being released into modern ecosystems. In the worst cases, up to one-third of host species were destroyed.
Even otherwise healthy children can end up in hospital with this winter respiratory virus.
