This study aimed to learn about the safety and real-world effects of the approved COVID-19 medicine Paxlovid. Over 3,300 participants aged 12 and up who were prescribed Paxlovid were followed for 28 days. Researchers watched for any side effects and checked whether their COVID-19…

This trial tested whether a combination of two existing drugs (famotidine and celecoxib) could help hospitalized COVID-19 patients recover faster and prevent severe illness in newly infected people. The study was small, with only 4 total participants, and aimed to see if this dru…

This study tested new portable sensor devices designed to quickly identify specific infections like COVID-19, Pseudomonas bacteria, and Leishmania parasites in patient samples. Researchers compared these new tests against standard lab methods to see if they were accurate, fast, a…

This study aimed to see if saliva tests could work as well as or better than the standard nasal swab test for finding COVID-19. Over 5,000 people who were getting a standard nasal swab test also provided a saliva sample. Researchers compared the results to see if the easier, more…

This study tested whether two existing drugs, azithromycin and hydroxychloroquine, could prevent COVID-19 infection in hospital workers frequently exposed to the virus. Over 120 healthcare workers who tested negative for the virus were randomly assigned to receive one of the drug…
