Health authorities estimate each infectious person could pass the virus onto two others.
There's no evidence you can spread the Wuhan coronavirus before showing symptoms, but one study suggests it's possible for children and young people to be infectious without ever having symptoms.
Chinese scientists sequence coronavirus causing pneumonia outbreak in Wuhan. And it's never been seen before.
Bacteriophages are viruses that attack and infect bacteria.
While some viruses make us sick, others can fight against bacteria, or protect us from more harmful viruses.
Human Cytomegalovirus affects billions of people all around world so why haven't most of us heard of it?
Monitoring sewage for virus allows for a quick public health response if any polio is detected.

Polio can be circulating through a community long before anyone is paralyzed. Monitoring sewage for the virus lets public health officials short-circuit this 'silent transmission.'

The Democratic Republic of the Congo has been hit with another Ebola outbreak. This may be the test case for how to deal with future outbreaks.
People and animals live side by side – and can have pathogens in common.
No one then knew a virus caused the 1918 flu pandemic, much less that animals can be a reservoir for human illnesses. Now virus ecology research and surveillance are key for public health efforts.
Many in the Western Front contracted haemorrhagic dysentery.

When commemorating our troops, doctors and nurses this Anzac Day, consider also tipping your hat to the discovery of bacteriophages. In the post-antibiotic era, our health might just depend on them.
Cytomegalovirus infection in the womb is more common in Australia than infection with listeria or toxoplasma in pregnancy.
We can prevent congenital deafness and intellectual disability due to cytomegalovirus by simple hygiene measures. So, why don't pregnant women know about this?
GMOs may very well have filled up that syringe.

Public health experts enlist the molecular biology tools that create genetically modified organisms – as well as the GMOs themselves – in the fight against emerging infectious diseases.
The climate is startlingly complex, as is the immune system.
Diverse threads of the vast interrogation of nature we call science are coming together in a rich and mutually informative intellectual tapestry.
Spread by mosquitoes.
Could this relatively unknown virus become a household name in the Americas in the year to come?
‘Leaky vaccines’ don’t affect the ability of the virus to reproduce and spread to others; they simply prevent it from causing disease.

Media coverage of a recent study involving a "leaky" vaccine raised questions about the possibility that they could make viruses more dangerous.
The pathogens are secured, but are the data about them as well-protected?
Biosafety needs to be about more than personal protective equipment and safe laboratory practices. Don't forget the cybersecurity.
Try to predict the outcome of a single coin toss and you’ll have only a 50-50 chance of being correct.
Predicting infectious disease outbreaks is a tricky task to begin with. And it's made harder still by the fact that any individual outcome is subject to unpredictable – or stochastic – effects.
Isolating the antibodies.
Immunotherapy has joined anti-retroviral drug therapy as a means to combat HIV.

This morning you woke up feeling a little unwell. You have no appetite, your head is aching, your throat is sore and you think you might be slightly feverish. You don’t know it yet, but Ebola virus has…
Nowhere to hide: HIV-1 on the surface of a white blood cell.
HIV uses an “invisibility cloak” made up of a host body’s own cells, a team of researchers has found, in a discovery that…
Primates - human and non-human - can be infected by Ebola.
As viruses go, Ebola is one that strikes particular fear. It’s infectious and four out of the five identified strains can cause severe hemorrhagic fever, which in later stages leads to bleeding from the…
Out of the lab and into real life.
As a virologist working in the Gambia, the idea of a portable microscope that uses fluorescent imaging and can be attached to your smartphone to detect viruses and bacteria in the field sounds amazing…
