The hottest Rapid Testing Substack posts right now

Rapid antigen tests (RATs) are crucial despite delays in testing positive after symptoms - it's essential to use them more, not less, to catch infections early.
Symptoms like cough and brain fog can precede positive RAT results, but do not indicate contagion - testing should happen a few days after symptoms start to confirm infection.
Current guidelines recommend testing too early after symptoms; waiting 5 days to test after symptom onset is more accurate - understanding this can help prevent the spread of the virus.

Rapid antigen tests can help make events safer by reducing the risk of someone infectious attending, but they are not foolproof. Testing before an event and daily can help manage the risk of potential spread.
The use of rapid tests can potentially lead to a sense of complacency regarding social distancing and mask-wearing, so it's important to have a clear plan in place in case someone tests positive at the event.
In the end, having everyone vaccinated is crucial, with testing serving as an additional layer of protection especially in high-prevalence situations. However, there are no guarantees, so decisions should be made based on the specific circumstances.

Regular rapid antigen testing in schools can help prevent disruptions and keep schools open by catching infectious cases
Using daily testing in schools can lead to significantly fewer school days lost and staff absences due to Covid-19 compared to mandatory isolation measures
Denmark recommends regular testing for school children as a measure to control the spread of Covid-19

Some recent articles highlight the need for better masks for workers.
Improving vaccination supply can be done with minor changes like using different syringes.
Evidence suggests that schools, especially for younger children, may be able to open up with flexibility.

Frequent and rapid testing plays a key role in limiting the spread of viruses like COVID-19.
The frequency of testing and the accuracy of the tests are crucial in determining how effectively infectious individuals can be isolated.
Testing every two to three days with a moderate error rate can be more effective than testing less frequently with higher accuracy.
