Despite awareness of the importance of hand washing, most people often fail to do it properly.

A common myth cited as a reason for not getting the flu shot is that the shot will give you the flu. That is scientifically impossible. Here's why.
Candida auris fungi, is becoming resistant to many anti fungal drugs.
When people get sick, they often suspect bacteria and viruses as the cause. But now the CDC is asking physicians and patients to consider another culprit: fungi.
Industrial vaccine production has enabled mass vaccination campaigns that have reduced infectious diseases.
Recent discoveries on the effects of live attenuated vaccines challenge the current vaccine paradigm and question vaccination policies.
The oral polio vaccine is most commonly used in the developing world, despite one big problem.

A challenge in eradicating polio comes from a version of the vaccine itself, which relies on live but attenuated virus. Rationally designing a new vaccine could help get rid of polio once and for all.
When you’re feeling sick, your immune system is fighting to get you well again.
The white blood cells act as an army of fighting cells, protecting your body from bad cells known as germs. White blood cells can capture germs and even swallow them.
A small trial suggests a powerful new way of beating non-muscle invasive bladder cancer.
Human Cytomegalovirus affects billions of people all around world so why haven't most of us heard of it?

Monkeypox is very contagious and there is no cure. But the good news is the body can heal itself from the virus. Singapore is the first in Asia, where the monkey smallpox virus has infected humans.
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.
Viruses attack and infect a bacterium.
Cholera kills fast, and outbreaks are common in war-torn regions and after natural disasters where clean water is scarce. A new strategy to prevent cholera infections is a 'cocktail' of live virus.
In most cases, scientists are still unsure of what causes Alzheimer’s disease.

After the failure of multiple drug trials the outlook for an Alzheimer's drug is bleak. This shouldn't be a surprise. We don't know the cause or even how to diagnose the disease.
The flu comes on rapidly and symptoms get worse over the first few days.
The 2018 flu season was mild, while 2017 was a particularly bad year. It's impossible to predict what the 2019 flu season has in store, but we've seen more cases so far this year than usual.
The Ebola virus.
The Ebola virus claimed 11,000 lives in 2014. Today, scientists may have cured the disease in guinea pigs by using antibodies.
The latest malware is designed especially to make small companies pay through the nose for their data.
These are viruses called bacteriophages that infect only bacterial cells.
Bacteria are becoming resistant to even the most powerful antibiotics. These expensive, hard-to-treat infections are prompting physicians to reassess using viruses to destroy bacteria.
Ant infected and killed by entomopathogenic fungus.
New research shows teaming fungi with 'friendly' viruses could create an environmentally sustaiable and efficient way to protect crops.
This is a model of the adenovirus type 5 which causes respiratory infections.
When you think of viruses, you might think of the horrible illnesses they cause, like flu or Ebola. But now researchers are learning how to use the unique traits of viruses to treat disease.
People may unknowingly bring measles back from other countries, including Europe.
We've had the measles vaccine in Australia since 1968, but a two-dose program was only introduced in 1992. And if you haven't had the second dose, you're at risk of contracting measles.
Scientists still rely on a set of 19th century postulates to identify disease-causing organisms but more than 100 years of research shows why we need to move on.
