Study: At-Home Rapid COVID Tests May Miss Many Infections

According to a new study, rapid antigen tests may provide false negatives — suggesting that a person is infection-free, even though other parts of their respiratory tract are teeming with the virus. The researchers found that most people showed a delay of several days between when the virus first appeared in the throat or saliva and when it appeared in the nose. Importantly, 15 of the 17 study participants had high levels of the virus for at least a day prior to getting a positive result.

Covid-19: Metformin reduces the risk of developing long term symptoms by 40%, study finds

Metformin—a cheap, safe, and widely available diabetes drug—could reduce the incidence of long covid if given during the acute phase of covid-19, a new study indicates.

A two week course of metformin given within three days of testing positive for SARS-CoV-2 led to 40% fewer long covid diagnoses over the following 10 months compared with people who had taken placebo, according to a randomised controlled trial.

Could fused neurons explain COVID-19’s ‘brain fog’?

Researchers have demonstrated that a SARS-CoV-2 infection can induce brain cells to fuse together, with severe impacts on the functioning of neurons. Neurons may fuse together with other neurons or glia, and larger multicellular syncytia may be formed. The fusion of neurons may be one of the causes of the cognitive issues associated with COVID-19.
