The flu comes on rapidly and symptoms get worse over the first few days.
The 2018 flu season was mild, while 2017 was a particularly bad year. It's impossible to predict what the 2019 flu season has in store, but we've seen more cases so far this year than usual.
We need a community conversation about balancing the trade-offs.
Australia's college of obstetricians has warned pregnant women against kissing their toddlers on the mouth or sharing food because of the risk of cytomegalovirus (CMV). But is this advice useful?
The Nipah virus in India is just one example of a viral outbreak in 2018.
It doesn't just seem like the world is experiencing more viral infections than before – it's a reality. And the way humans live today helps viruses thrive.

A clinical trial currently underway in France could confirm that that HIV treatment can be safely reduced to just four days a week, while maintaining the same efficacy.
To finish, or not to finish, your course of antibiotics? There’s little doubt that you shouldn’t stop midstream.
New reports that stopping antibiotics when you feel better is better for you could do more harm than good. But it has reopened the debate on how long antibiotics should be used.
What can a single person’s flu infection tell you about how the virus changes around the world?

New genetic technologies are letting us look at flu evolution right where it starts: within individual people, while they're sick.
The thing all five viruses have in common is they can cause mild to very severe liver damage.
Hepatitis A, B, C, D and E are very different viruses. Hepatitis A is genetically closer to the common cold than it is to hepatitis B. Hepatitis C is closer to the virus that causes dengue fever.
A virus is essentially an information system (encoded in DNA or RNA) surrounded by a protective coat.
Humans have a deep history of viral infections, the evidence for which dates back to ancient DNA from Egyptian mummies.
The immune system protects us from the constant onslaught of viruses, bacteria and other types of pathogens we encounter throughout life. But it can sometimes misbehave.
Viral mutation, or ‘genetic drift’, could impact the viability of some drugs being developed to combat Ebola.
Scientists around the world are trying to develop effective treatments for Ebola infection. But a process of viral mutation, known as "genetic drift", could potentially compromise their efforts.
Only a small proportion of people who eat these berries will become infected.

As long-frozen parts of Earth thaw, it’s inevitable that old viruses will be unearthed. What risks do they have to humans?
You may have seen recently that scientists recovered and “revived” a giant virus from Siberian permafrost (frozen soil) that dates back 30,000 years. The researchers raised concerns that drilling in the…

A primary carrier of the Chikungunya virus, the Asian tiger mosquito (
Aedes albopictus) could easily hop to mainland Australia from Torres Strait islands.
Chikungunya is a virus transmitted to people by mosquitoes; it usually causes a non-fatal but debilitating illness. Despite thousands of people being infected each year in Africa, Asia and Melanesia, chikungunya…
