Effect of High-Dose Zinc and Ascorbic Acid Supplementation vs Usual Care on Symptom Length and Reduction Among Ambulatory Patients With SARS-CoV-2 Infection: The COVID A to Z Randomized Clinical Trial

Results of a randomized trial among 214 patients with lab-confirmed COVID-19 suggest that high-dose zinc, high-dose ascorbic acid (vitamin C), and a combination of the two do not significantly change the duration of symptoms. Patients who received usual care without supplementation achieved a 50% reduction in symptoms at a mean of 6.7 days compared with…

Comparison of Severe Acute Respiratory Syndrome Coronavirus 2 Screening Using Reverse Transcriptase-Quantitative Polymerase Chain Reaction or CRISPR-Based Assays in Asymptomatic College Students

Rauch et al. concluded that CRISPR-based methods appear to offer reliable SARS-CoV-2 screening based on testing 1,808 asymptomatic college students with both RT-qPCR and CRISPR-based assays. Of the nine samples that tested positive by RT-PCR, eight were also positive by CRISPR-based assays, which are cheaper to run and use lab-generated or off-the-shelf reagents, potentially alleviating…
