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.
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, the cost of reaching herd immunity during a pandemic is counted in lives lost, and it won’t quickly stop the virus’s spread.
‘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.
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?
People have lived with infectious disease throughout the millennia, with culture and biology influencing each other. Archaeologists decode the stories told by bones and what accompanies them.
Detecting fever requires measuring core body temperature. Screening measures the body’s surface temperature.
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.
Why does COVID-19 hit men harder than women? Is the disparity in mortality rates due to male hormones or an underlying difference in the male versus female immune system?
Our experts look at why people of colour are being hit harder by COVID-19, New Zealand’s success in eliminating the virus, and the latest on drug trials.
Superbugs spread through the environment – and it needs urgent attention.
This winter, the field of respiratory viruses will be crowded.
The South African government and some of its advisors want to have the best of both worlds. They want to use incorrect predictions by early models about the COVID-19 pandemic to claim success.
In the hope of finding a cure for COVID-19, it is easy to get lost in the hype. But chloroquine and hydroxychloroquine should for now be set aside.
Epidemiological data suggests that 80% of COVID-19 cases can be traced to just 20% of those infected with SARS-CoV-2.
The virus that caused the original Sars no longer haunts us, but the characteristics of today’s coronavirus mean it’s unlikely to disappear in the same way.
