People have lived with infectious disease throughout the millennia, with culture and biology influencing each other. Archaeologists decode the stories told by bones and what accompanies them.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
Your body wants you to freak out about germs so you avoid them.

In the real world, new diseases emerge from complex environments. To learn more about how, scientists set up whole artificial ecosystems in the lab, instead of focusing on just one factor at a time.
Whether by biology or behavior, some people in the crowd will transmit coronavirus to more than the average number of others.

The novel coronavirus spreading outward from Wuhan, China, will get an assist from a subset of infected people who transmit it to many others.
What happened to make plague able to cause devastating epidemics, as in this depiction from 1349?

People caught and died from plague long before it caused major epidemics like the Black Death in the middle ages. Could what scientists call cultural resistance be what kept the disease under control?
Spraying insecticide to kill mosquitoes: Mosquitoes are vectors of many devastating diseases such as malaria.
In the ongoing arms race to kill off mosquitoes that spread malaria, researchers have modified a naturally occurring fungus that kills mosquitoes with a deadly toxin to wipe out these insects faster.
Once a respiratory virus like influenza has entered your home or workplace, it is wise to treat the space like a hospital and practice infection prevention and control.
From face-touching to virus-contaminated electronic devices, a scientist offers some tips on eradicating the flu virus from your home.
A virus like SARS can shut down cytokine production, enabling it to multiply to higher levels and causing significant infection and even death.

We've all endured infections. Here's how it works when our bodies are attacked by viruses, bacteria or parasites, and our innate immune system becomes the first line of defence.
When governments delay releasing information about disease outbreaks, algorithms come to the rescue.
The original antigenic sin has made fighting diseases really difficult.
Innovative initiative aims to inspire pupils on the continent to take up careers in science.
