‘One Health’ keeps humans one step ahead of the microbes

As new viruses “jump” from wildlife to humans and we struggle with antimicrobial resistance and even climate change, a new interdisciplinary approach to human health might just save the day.

Recent discoveries of ancient viruses are helping scientists understand their origins.

Can bats help humans survive the next pandemic?

Scientific studies show that bats may carry “coronoviruses” causing SARS and MERS - without showing symptoms of disease. Could the bat immune system be key to human survival in future pandemics?
A virus like SARS can shut down cytokine production, enabling it to multiply to higher levels and causing significant infection and even death. (THE CANADIAN PRESS/Kevin Frayer)

Explainer: How the human body first fights off pathogens

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.

The Ebola outbreak highlights shortcomings in disease surveillance and response – and where we can do better

Along with better strategies to respond to outbreaks in human populations, we need a stronger focus on surveillance in animals to identify infectious diseases before they pose a risk to human health.

Explainer: what exactly is coronavirus?

If you’ve never heard of coronaviruses before, you may know about some of the illnesses different types of they can cause, like SARS, Middle East Respiratory Syndrome and the common cold.

Viral incubation: why do bugs hide before they strike?

Health workers returning to their home countries after working in Ebola-affected areas are being asked to place themselves in quarantine for 21 days. This period is important because it’s the maximum time…
