Reports describe a Hong Kong man who was reinfected with the coronavirus after returning from Europe. Does that mean he wasn't immune after the first infection?
Some people who have never had COVID-19 have the antibodies to fight it – possibly from an earlier infection with a different coronavirus.

We don't have vaccines for the Sars, Mers or the common cold. But that doesn't mean scientists won't crack it this time.
Ever heard of 229E, OC43, NL63 and HKU1?
Can you smell this?
Patients who later test positive for COVID-19 are reporting early loss of smell and taste. Researchers are now trying to understand if this could be an early sign of the disease.
You'll catch your death!
Getting rid of this scourge is nothing to be sneezed at.
One nostril or two? Hard blow or gentle? Some ways are more effective and less risky than others.
If you have a blocked or runny nose, chances are you'll reach for a tissue or hanky for a good blow. But is your technique up to scratch?
Antibiotics are wrongly being prescribed for infections where they won't work and cutting this down could help combat resistance. But change isn't as easy as just providing the means.
Antibiotics provide no benefit for the common cold and other respiratory illnesses caused by viruses.
The most contagious phase of a cold is early in the “runny nose” phase – not later when the secretions become coloured.
More people end up in hospital from cold than flu.
The “common cold” is common, most of us will have at least one or two per year. Despite this, there's a lack of good research looking into it, and ways to prevent and treat it.
‘Clinically proven’ to shorten your cold? Not quite.

We recently submitted a complaint about the promotion of Ease-a-Cold products, which claim to be “clinically proven” to shorten your cold.
Emerging science could help us gain a better understanding of the annual phenomenon of students falling ill when they head back to uni.
People who have big weekends tend to take more sickies at work.
There's no doubt chronic alcohol abuse changes the body's infection-defence system. But here's what the research says on whether a binge-drinking weekend can make people more susceptible to illness.
The more we take antibiotics, the more likely we are to have superbugs down the line.
Antibiotics can prevent serious harm and stop infections becoming fatal. But they won't kill common cold and flu viruses, and careless overprescribing by doctors can do more harm than good.
People aren’t productive at work when they’re ill and they risk infecting others.
You wake up and feel under the weather. If you're vomiting or have a fever, the decision to stay at home is probably clear cut. But what if you generally feel unwell but are torn about missing work?
If your symptoms are above the neck, you’ll still be able to manage a lighter-than-normal workout.
As we move into winter, the cold mornings, dark evenings and rain tend to bring out the best excuses to miss a session at the gym or run around the park.
Cold and flu tablets won’t cure a cold.
Pharmacies have aisles full of cold and flu tablets. But which product is the best one for you? And will it really help you feel better?

If you’ve never heard of coronaviruses before, you may know about some of the illnesses different types of they can cause, like SARS, Middle East Respiratory Syndrome and the common cold.
People know that antibiotics won’t help viruses. So why ask doctors for antibiotics?
Antibiotic resistance is a major threat to public health. Resistance makes it harder for physicians to treat infections and can increase the chance patients will die from an infection. What is more, the…
