Although millions are navigating long COVID, four years into the pandemic both patients and their caregivers continue to face challenges accessing the information and care they need.
Detecting infectious agents in sewage is only the first step. Researchers are working on developing reliable ways to translate surveillance measurements to case numbers and infection predictions.
Research shows that rapid antigen tests are performing as well at detecting the most recent dominant variants as they did with the earliest strains in the COVID-19 pandemic.
Two new high-profile studies add to the increasingly worrisome picture of how even mild cases of COVID-19 can have detrimental effects on brain health.
The JN.1 variant has become dominant in Australia and around the world, causing large waves of infections. Here’s what we know about it so far – and why it’s so important.
This is an era of exciting advances in medical science. But Africa is in danger of being at the back of the queue once again. What should we be doing to make sure this doesn’t happen?
How are people with long COVID faring two years after their initial infection? Many have recovered. Some still struggle with symptoms – this is more likely for those who were initially hospitalised.
As COVID finds its equilibrium, infection rates will rise and fall, influenced by seasons, school holidays and new subvariants. Managing the risk is complex and needs to be cost effective.
The World Health Organization has classified the EG.5 family of Omicron variants, including Eris, as ‘variants of interest’. What does that mean? And how does Eris differ to other Omicron variants?
Health workers who picked their noses were more likely to contract COVID, according to a new study. But here’s what the study means for the rest of us.
