About 10% of COVID-19 patients will experience continuing symptoms for 12 weeks or more following diagnosis.

There’s no one-size-fits-all approach for long COVID treatment, but exercise focusing on breathing and pacing yourself throughout the day often helps.
This variant seems to be causing a new symptom not commonly seen with earlier COVID strains.
Knowing if you have COVID or the flu can affect when you get vaccinated, need a particular antiviral, or if you need to work from home. But these combination tests can be expensive.
Certain immune cells acquired from a coronavirus that causes the common cold appear to react to COVID – but more so in children that adults.
Covid-19 exposed critical shortcomings of existing diagnostic techniques.

The pandemic spurred the diagnostics industry to consider aspects like scale, affordability, speed and portability of tests.
New reports suggest the pandemic’s origins may be linked to raccoon dogs sold at Wuhan’s Huanan Wholesale Seafood Market. A virologist explains.
Previous infection was highly protective against reinfection with alpha, beta and delta variants, but less so against omicron BA.1.
A team from the University of Tours and INRAE is working on the development of an innovative nasal vaccine against Covid, in spray form.
Vaccination is often combined with an injection. It can also take the form of a nasal spray: an approach that is still rare, but which could be effective against Covid. Here’s why.
Scientists are trying to find out whether there’s a genetic reason certain people have managed to avoid COVID for three years.
As it became clear that the solution to the COVID pandemic would come from medical research, many people volunteered for human challenge trials.
XBB.1.5 and other subvariants do signal a change in how the virus is mutating. Here’s what this means for Australia and globally.
An accurate count of COVID-19 deaths is critical both scientifically and politically.

Taking into consideration the number of excess deaths caused by COVID-19 compared with pre-pandemic years is critical to getting an accurate accounting of the pandemic’s real toll.
Nearly all the wastewater samples from aircraft arriving in the UK showed evidence of COVID-infected passengers on board.
The northern hemisphere has seen a surge in winter viruses.
A couple of theories are popular for explaining why we’re currently seeing very high levels of respiratory viruses, but they’re not based in science.
Many viruses interact with the olfactory system, and can damage other areas of the brain through it.

Inflammation and damage to the olfactory system from shingles, COVID-19 and herpes infections may contribute to Alzheimer’s disease.
XBB.1.5 is rapidly spreading across the globe and will likely become the next dominant COVID-19 subvariant.
The XBB.1.5 subvariant — nicknamed ‘Kraken’ — is arguably the most genetically rich and most transmissible SARS-CoV-2 Omicron subvariant yet.
XBB.1.5, or ‘kraken’, can evade our immune systems better than earlier variants, and appears to be more infectious. But it’s not cause for alarm.
After a year of omicron variants, will we ever see a new variant of concern?
Nasal vaccines for COVID-19 are still in early development.

An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Some results of independent testing of rapid antigen tests available in Australia have been made public. Here’s what the data tell us.
