Imported frozen pomegranate seeds have been linked to hepatitis A infections in NSW.
Hepatitis A is a virus that infects the liver. Symptoms usually take 15-50 days to develop after initial infection and typically last for several weeks or sometimes longer.
Young children catch and spread the flu more than any other age group.
The flu vaccine isn't perfect but it's the best way to protect against these potentially harmful viruses. Most children aged six months to five years are eligible for a free vaccine in 2018.
Watching bacteria and viruses duke it out, evolving to outwit each other.

A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
What will it take to finish polio off in the last three countries where it persists?

Pakistan had only eight new diagnoses of polio in 2017. The virus' days look numbered – but health workers have their work cut out for them to eradicate the devastating disease once and for all.
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.

There's a norovirus outbreak at the Winter Olympics. Here's what that means – and why it's so hard to stop.
Women's rights and poverty cannot be ignored.
Could the yearly flu shot become a thing of the past?

Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But rational design – a new way to create vaccines – might pave the way for more lasting solutions.
Once a respiratory virus like influenza has entered your home or workplace, it is wise to treat the space like a hospital and practice infection prevention and control.
From face-touching to virus-contaminated electronic devices, a scientist offers some tips on eradicating the flu virus from your home.

Anyone who's had the flu can attest that it makes them feel horrible. But why? What is going on inside the body that brings such pain and malaise? An immunologist explains.
No cases of feline parvovirus were reported from the 1980s until 2015.
The good news is there's a vaccine to prevent feline parvovirus.
Despite new findings, the deaths can't be blamed on enteric fever alone.

We need balanced media reporting about bat-borne diseases to help avoid vilification of Australia's under-appreciated creatures of the night.
An annual vaccine is your best protection against the flu.
After Australia's tough flu season, some experts predict that the U.S. is in for a few difficult months. What does that mean for you?
Delivering genetic material is a key challenge in gene therapy.

One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients' bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
Current plans to eradicate polio mean keeping the virus alive – and risk restarting the epidemic.
Bad news on the doorstep. How to stay safe?
Like the recent WannaCry, viruses and other hacker software are now part of our digital lives. How big are the threats? How can we protect ourselves?
Bats are the only mammals capable of true flight. Scientists believe flight may influence their immune responses to coronoviruses, which cause fatal diseases such as SARS and MERS in humans.
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?
