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.
Surface proteins on a virus enable it to attach to and get inside a cell to start replicating.

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 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.
Despite an abundance of research on strep, there is still a great deal of debate in the scientific community over whether and when people should get tested and treated for it.
Yep, when you’ve finished, both of those need to go in the wash.

Although testing for CMV during pregnancy isn’t routine and there isn’t universal screening for infants, there are steps pregnant people can take to protect themselves and their newborns.

Babies guts found to have ten times as many viral species as bacterial species.
Certain factors can disrupt the gut microbiota. These include our diet, alcohol consumption, antibiotics and inflammatory bowel disease.
