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.
Most cases of Zika are asymptomatic.

A computer model suggests that while more cases of Zika can be expected in the continental U.S. outbreaks will probably be small and are not projected to spread.
Your child will receive a meningococcus vaccine, but it doesn’t cover all the subtypes.
Stories of meningococcal outbreaks tell us it's that season again. But what is meningococcal, why does it occur in seasons, and why does it strike fear into the hearts of so many?

While no one likes getting bitten by mosquitoes, you might be surprised (and even a little fascinated) at the complex adaptions mosquitoes have developed to locate their favorite food sources.
With more birth abnormalities linked to Zika, effects of the virus may be more sinister than we thought.
Arthrogryposis is where a baby's joints are deformed due to a shortening (known as contractures) of the muscles from before birth.
Two-thirds of children have already received antibiotics by the time they are one year old.
If you have a ten-month-old baby, what do you need to know? What do you need to ask your GP about the benefits and risks of antibiotics?
Talking with patients who’ve had Zika is tough.

Physicians like me are learning about Zika along with our patients. This takes a dose of humility on our part and an understanding from our patients that we learn something new every single day.

Those who enter prison uninfected are at risk of becoming infected.
Worldwide, around 30 million people enter and leave prison each year. Of these people, around 4.5 million have hepatitis C, almost 1 million have HIV and 1.5 million have hepatitis B infections.
Cases of AIDS are so few they are no longer recorded on public health registers.
There are good reasons for drawing attention to “the end of AIDS” in Australia. But this needs to be read with caution.
Some 60% of bugs that infect humans originated in animals.
The world’s scientific community is focused on how to improve detection and responses to emerging diseases such as Zika virus and Ebola. So what can we learn from the most recent large-scale outbreaks?

Unless drinking water and sanitation infrastructure are improved, cholera could remain in Haiti indefinitely.

Many people in the U.S. have no idea that TB is still found here, or what a major health risk it poses in other parts of the world.

Models based on where the mosquitoes that transmit Zika are found and human travel patterns to and from infected areas are key to predicting where the virus will spread.

Zika was discovered almost 70 years ago, but wasn't associated with outbreaks until 2007. So how did this formerly obscure virus wind up causing so much trouble in Brazil?
Early necrotising fasciitis is easily missed because the symptoms – fever, pain, swelling and tenderness at the affected site – may be non-specific or confused with a mild, superficial infection.
Necrotising fasciitis is a serious infection that affects the soft tissue.
All we are is just a link in the chain?

Missing links make a good story, but not good science. Outdated metaphors don't help us understand the rapid evolution of infectious diseases such as flu and malaria.

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.
