There are so many forms of the virus, it’s hard to keep up. Here’s what to expect next as the virus mutates and recombines.
Two new omicron subvariants, BQ.1 and BQ.1.1 could lead to another COVID surge. Here’s what we know so far.
Technique matters when it comes to getting a sufficient amount of virus for a rapid test.

Rapid tests can be an incredibly useful tool for early detection of COVID-19. Unfortunately, they sometimes leave people with more questions than answers.

Adding COVID-19 to a list of ‘designated diseases’ will not make vaccination mandatory for school entry. But it may help increase COVID-19 vaccine uptake among children.
As the virus that causes COVID evolves, keeping up with it remains a challenge for variant-specific vaccines. The booster you can get now is the best one to get.
Sotrovimab and casirivimab-imdevimab are no longer recommended for patients with COVID.
This guidance replaces previous conditional recommendations for the use of these drugs and is based on emerging evidence that they’re not likely to work against omicron.
BA.4.6 seems to be even better at evading our immune response than BA.5.
As of August 2022, COVID-19 vaccination rates in Black and Hispanic people exceeded those of white Americans nationally, but only for the initial shots.

Early on, public health messaging focused on the need for vaccines to combat COVID-19. But far less attention has been given to the role of boosters in preventing deaths and reducing inequities.
The UK has become the first country to approve the shot, which targets omicron alongside the original strain of SARS-CoV-2.
Just because a variant spreads faster, it doesn’t necessarily mean it has a higher R0.
The new BA.5 subvariant has caused a sharp rise in cases and hospitalizations throughout much of the United States.

Face masks are still an effective way to help stop the spread of the BA.5 subvariant.
The last Omicron wave affected younger people. But the new BA.5 variant is seeing case numbers in older age groups higher than ever before – just as hospitals are under the most pressure.
Is it time for a new generation of COVID vaccines? Here’s where the research is at.
Achieving herd immunity via vaccination was always going to be a hard ask. Now it’s mathematically impossible.
COVID vaccines may lose effectiveness against Omicron, but one more dose could remedy this.

Understanding the depth of vaccine hesitancy, and the drivers behind the lack of take-up is critical to preventing further deaths, infections, and continuing harm to the economy.

The COVID isolation period is seven days in Australia, but you might still be infectious after that if you have symptoms and a positive RAT.
About 8 million U.S. children have received two shots of COVID-19 vaccine and are now eligible for a third.

The COVID-19 vaccines continue to be effective against severe illness leading to hospitalization and death in all age groups, including children ages 5 to 11.
What’s the difference between a variant and a subvariant? It’s all in the behaviour.

At this stage of the pandemic complacency is likely to lead to an increase in cases, hospitalisation, morbidity and mortality.

Repeated resurgences of SARS-CoV-2 transmission are expected in the years to come.
