The outbreak of Zika virus in Brazil had Australian travellers on alert but transmission is only possible in tropical Queensland.
New research shows common local mosquitoes aren’t able to spread Zika. This means Australia is unlikely to see a major outbreak of the disease. But a risk remains in northern Queensland.

News about the sewage and pollution in Guanabara Bay in Rio have caused health concerns among Olympic athletes.
Wastewater treatment systems around the world are hamstrung by outdated tests that don't identify a growing array of pathogens or identify the sources of pollutants.
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.
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.
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?

Goldfish might look nice, but they can also spread a variety of decidedly not-nice viruses.
Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.
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.
They might look like an alien species, but these bacteria-eating viruses could be the next big thing in the fight against infectious diseases.
