The health care system is hemorrhaging medical lab workers, in part because of COVID-19 infections and also because of burnout, low wages and better opportunities elsewhere.
Are economic drivers the reason for the reduced isolation period in the UK?
To discover your risk of catching coronavirus for any given situation, try our COVID-19 Aerosol Transmission Estimator.
Even with a variant like Omicron that may be more transmissible than earlier variants, vaccines remain the most effective tool for protection against COVID-19 and for ending the pandemic.
A nationwide genomic surveillance system analyzes positive COVID-19 tests to build a picture of which variants are spreading in the population.
Free rapid antigen tests makes public health sense and economic sense.
SARS-CoV-2 cannot improve indefinitely.
DNA sequencing has allowed researchers to catch new COVID-19 variants hours after receiving the first positive test sample.
Nearly all suicide-loss survivors experience guilt, wondering what they could have done to prevent it. But despite decades of research, experts struggle to identify risk factors and predict suicide.
Rapid testing for COVID-19 is an extra safety measure that can help prevent spread of infection, and help you have a more normal holiday, especially if you are visiting vulnerable people.
Early data show that Omicron is dominating new COVID-19 cases in Gauteng province.
At this stage, we cannot say anything about the severity of cases with Omicron - either in primary or reinfections.
Knowing when and how often to use rapid tests is key to getting an accurate picture of your COVID-19 status.
Careful lab work will complement public health data as researchers worldwide focus on omicron, asking questions about contagiousness, severity of disease and whether vaccines hold up against it.
It’s worth having a conversation with family and friends to set some rules to minimise the risk of COVID transmission.
Efforts to improve vaccine uptake must be tailored to the needs and concerns of the individuals and families who make up society.
How we should manage uncertainty is not a scientific issue but an ethical issue.
After a nose swab tests positive for a virus or bacteria, scientists can use the sample’s genetic sequence to figure out where and when the pathogen emerged and how fast it’s changing.
It’s too early to say whether the newly identified omicron variant is going to overtake delta. But particular mutations in the new strain have researchers deeply concerned.
