Computer modelling can help in the fight against the spread of disease.
It took a computer to discover the potential threat of a drug-resistant strain of swine flu that was about to spread from New South Wales. So how close did we come to a global pandemic?

The number of new Zika-related microcephaly cases in Brazil is falling. But it's too early to relax.
They might look like an alien species, but these bacteria-eating viruses could be the next big thing in the fight against infectious diseases.

Bats can carry some of the deadliest diseases known to affect humans and yet they don't seem to get sick. So what can we learn from a bat's immune system?

Two major clinical trials will be conducted in South Africa in 2016 to test ways of preventing new HIV infections.
Viruses are not all bad. In fact, many ecosystems would not function without them.
The word "virus" strikes terror into the hearts of most people. But most viruses are actually vital to our very existence.
Understanding where and how the virus hides on treatment is one of the biggest questions facing scientists working on HIV.

Ebola’s clever trick – to lie dormant inside a cell or to hide in a particular organ – is not unfamiliar. Lots of viruses do it. HIV is the master of such a trick.
Detecting viruses in wild-caught mosquitoes provides intimate detail of disease transmission cycles.

We monitor mosquitoes to help predict and control virus outbreaks. And a new technique for collecting mosquito saliva from the field has made the process both more sensitive and inexpensive.
These little-loved microbes may be coming in from the cold.
We don't trust bacteria and we don't trust GM, so putting them together might be controversial. That's exactly what we're doing, though.
