A mutating coronavirus has implications for vaccines, treatments, tests and your future plans.
An intriguing link could help us understand why men are at higher risk from COVID-19 than women. It also might pave the way for a potential treatment.

A century ago, the influenza pandemic killed about 50 million people. Today we are battling the coronavirus pandemic. Are we any better off? Two social scientists share five reasons we have to be optimistic.
France says one metre, Spain says two. But what really constitutes a safe distance when it comes to COVID-19?
SARS-CoV-2 has been observed in the tears of some sick patients, but this is an unlikely route of COVID-19 transmission.
Contact lenses are safe to use during the pandemic as long as you follow strict hygiene recommendations, including frequent hand washing.

Should the US be able to pre-order vaccines for its citizens when other populations around the globe are at greater risk?
Troy Sutton works with potentially deadly pathogens but the right precautions greatly reduce the risks.
To find a SARS-CoV-2 vaccine, scientists need to work hands-on with the highly infectious coronavirus. It happens in a super secure lab designed to keep them safe and prevent any escapes.

Pathogens typically face a trade-off between virulence and transmission. But that's not the case with SARS-CoV-2.
Coughing, sneezing, talking and even just breathing can produce airborne particles that can spread SARS-CoV-2.

SARS-CoV-2 can be spread through the air. But just how much of a factor that is has been hard to determine. Recent evidence suggests it is common, posing problems as public places begin to reopen.
Without a vaccine, getting to herd immunity would mean many more illnesses and deaths.

'Normal' body temperature varies from person to person by age, time of day, where it's measured, and even menstrual cycle. External conditions also influence your thermometer reading.
The scope and length of vaccine testing experiments usually mean decade-long timelines for development.
It usually takes 10 years for a new vaccine to complete clinical trials, but we've been promised a COVID-19 vaccine in 12 to 18 months. Even if such fast-tracked development is possible, is it wise?

If you have had COVID-19 already, are you protected from another bout of the illness? And is the presence of antibodies in your blood a guarantee of immunity?
For contact tracing to be effective, the UK needs quick, accurate testing and lots of tracing capacity – and also for the public to be on board.
Untreated sewage could be the best tracking tool we have to prevent a second wave.
Reports show that the mortality rate among men with COVID-19 is higher than women.
