At least 5,000 Australians die each year as a result of sepsis, more commonly known as blood poisoning.
With an ageing population, and the growing threat of antibiotic resistance, now is the time to be worried about sepsis.
Kids may need more exposure to dirt and microbes than previously thought.
Can your kids be too clean? Increases in allergies suggest so. But how much dirt is too much? A pediatric allergist explains the fascinating reasons the immune system needs dirt for training.
If you’re going overseas with your little one, you can vaccinate them against measles early. But they’ll still need their regular jab when they turn one.
Babies are normally vaccinated against measles at 12 months old. But doctors are now suggesting having the shot as early as six months might be worthwhile for youngsters traveling overseas.
You might feel terrible. But your runny nose, sore throat and aches are signs your body is fighting the flu virus. And that’s a good thing.
How can a tiny flu virus make you feel so bad, all over? Here's what's behind your high temperature, muscle aches and other flu symptoms.
They’re not perfect, but flu shots are still good to get.

The 2018-2019 flu season was less deadly than the last. But the pattern of infection was unusual, thanks to the various strains circulating and the way flu shots work over time.
Tennis player Venus Williams may have Sjögren’s syndrome but here she was, earlier this year, competing in the Miami Open.
Sjögren’s syndrome has no cure. Here's how it affects the body and what the future might bring for people with this challenging autoimmune disease.
There's more to antibiotics than meets the eye.
With food allergies on the rise, it's important to understand the role the skin plays in protecting or exposing us to reactions.
Are you exhausted? Your immune cells might be too.
The cornerstone of our adaptive immune system is the ability to remember the various infections we have encountered. Quite literally, if it doesn’t kill you, it makes your immune system stronger.
Flea, the bass player with the Red Hot Chili Peppers, suffered from chronic fatigue syndrome.
A better understanding of CFS could lead to new treatments.
Don't try this at home, kids.

Allison and Honjo discovered how inhibiting the brakes in our immune systems can be used to treat cancer.
If they are simply too large, your tonsils can be shrunk down using special instruments which remove the valleys and crypts.
Tonsil tissue is particularly important in the first six months of life. After this, our lymph glands take over most of the work and the tonsils are essentially out of a job.
By the time they turn one, half of Australian babies have had a course of antibiotics.
There may be additional long-term health harms from antibiotic exposure in early life and before birth, including an increased risk of infection, obesity and asthma.

Fungi perform a vital role in the biological cycle, but pose an increasing danger to human health – invasive fungal infections kill three times more people than malaria.
The immune system has to establish which cells belong to us and which are foreign, no mean feat.
Nobel laureate Peter Doherty explains immunity.
The physiological changes at the onset of schizophrenia are as marked as the mental changes, new study finds.
Migrating to Europe changed the immune systems of birds who no longer needed to worry about African diseases.
Health researchers fact check the idea that running a marathon suppresses your immune system.
