New technology could help doctors identify the right antibiotic for their patient in double-quick time.
Whooping cough is making a comeback. Here's how to identify it, and why vaccination is a way to protect babies.
A new body of research suggests that infections in childhood, along with antibiotic use, could impact the bacteria in our intestines and raise risks of mental health challenges in later life.
Research using massive databases -- such as the Danish Psychiatric Central Research Register -- is enabling a whole new understanding of the links between life history, the gut and mental health.
Ebola is a dreadful disease and is one of the deadliest infections known to medical science.
Instability in the DRC and Ebola's deadly properties is making it hard to contain the virus.
A study that more NHS managers actually lowered rates of infection and led to some improvement in patient satisfaction.
Antibiotics are only useful for treating infections caused by bacteria, not viruses or fungi.
It's hard to predict how long it will take to feel better after you start taking antibiotics. But if you start feeling worse one to two days after starting the therapy, you must see your doctor.
Hand washing is an effective way to help prevent the spread of bacteria.
Millions of bacteria live on our skin without making us sick. It's when they manage to get through that they can be dangerous – particularly if they're resistant to antibiotics.
Sepsis can maim or kill within hours. Here's how to identify the condition.
Slugs are voracious feeders.

New research uses pathology in dinosaur bones to look at predator-prey interactions in the fossil record.
For some children, ear infections will become a persistent problem.
Middle ear infections (otitis media) are a common and often painful condition that
most children will experience at least once in their first year.

There's a norovirus outbreak at the Winter Olympics. Here's what that means – and why it's so hard to stop.
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.
The usual culprit is the bacterium
Staphylococcus aureus, better known as “golden staph”.
School sores usually clear up within a few weeks, without any scarring. Here's what to do if you suspect your child has them.
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?
Researchers have found Australia’s first confirmed case of tularemia in a ringtail possum.
Tularemia is an animal disease that can be transmitted to humans. While it can be fatal, it is rare in Australia and can be treated with antibiotics.
People mainly think of GPs over-prescribing antibiotics, but ubiquitous use in farming and other areas also contributes to resistance in bacteria.
We need a concentrated and coordinated effort by government and scientists if we're to stave off the threat of antimicrobial resistant bacteria.
A hospital nurse checks the temperature of all visitors in Conakry (Guinea) in 2014, at the height of the Ebola epidemic.
One year after the end of the West African Ebola epidemic, a study of survivors in Guinea shows what has been learned about the deadly virus, and what remains unknown.
According to the World Health Organisation, antimicrobial resistance is now at crisis point.
The US Centers for Disease Control has reported a woman in her 70s has died of overwhelming sepsis caused by a bacterium that was resistant to all available antibiotics.
Easy to transport and store, skin patches could soon replace needles for vaccination.
Postage-stamp sized patches that target vaccines to the immune system are now in clinical trials.
