Saliva testing is less sensitive than a nasal swab. But in the midst of a public health crisis, in some cases a test with slightly reduced sensitivity may be better than no test at all.
Pooled testing is most efficient when applied in settings of low virus prevalence.
Pooling samples means one test can screen multiple people.

Screening multiple samples with a single test gets more people diagnosed using fewer supplies. Two health policy researchers explain how it works and how it could help the U.S.
We are slowly figuring out which drugs and therapies are effective against the new coronavirus.

During the last six months, news reports have mentioned dozens of drugs that may be effective against the new coronavirus. Here we lay out the evidence and reveal which ones are proven to work. Or not.
The U.S. as a whole is facing a huge surge in coronavirus cases, but the differences between states like New York and Florida are striking.

The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.
If a return to the office is on the cards, both employers and employees have a role to play in minimising the risk of COVID-19 spread.
SARS-CoV-2 turns on a cellular switch to build the tubes in this photo – called filopodia – that might help viral particles – the little spheres – spread more easily.

Kinases are cellular control switches. When they malfunction, they can cause cancer. The coronavirus hijacks these kinases to replicate, and cancer drugs that target them could fight COVID-19.

A simple computer model shows that safety measures can significantly impact both the exponential spread of COVID-19 and mortality rates.

China’s attempts to promote its actions and model of governance while discrediting the EU are not a short-term response to the pandemic, but part of a long-term strategy to build its international power.
Ongoing testing, say the authors, is critical to bringing back amateur sports.

Is it possible that people who recover from COVID-19 will be plagued with long term side effects from the infection? An infectious disease physician reviews the evidence so far.
Today smallpox can only be found in deep freeze inside a few highly secured laboratories, like this one at the CDC in 1980.
The smallpox virus appears to have been with humanity for millennia before a global vaccination drive wiped it out. Current genome research suggests how smallpox spread and where it came from.
Doctors reported the first cases of MIS-C in April. Learning more about how SARS-CoV-2 affects children is essential to the safe reopening of communities.

A rare new disease syndrome appears to be caused by an overactive immune response in children, often hitting weeks after exposure to the SARS-CoV-2 virus.
Screening for symptoms can catch some cases of COVID-19, but about people who are infected but not showing any symptoms?

There is a lot of confusion and concern around asymptomatic spread of SARS-C0V-2. An infectious disease expert explains how many people are asymptomatic and how they can spread the virus.
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.
Breathing in through the nose is an integral part of meditation and delivers virus-fighting gases to the lungs.

The body has many natural defenses against viruses and other pathogens. One antiviral molecule produced in the body is nitric oxide and it is created when we breathe in through the nose.

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.
