Detection and Containment
PCR and DNA Technologies
Applieddnasciences has reported on the SARS-Cov 69-70del mutant, seen in the B.1.1.7 Variant and others, and the success of their flagship PCR-based Linea COVID-19 Assay Kit.
In Vitro Diagnostics
A report from researchers in the UK looked at data from ~ one million people with positive coronavirus PCR tests and another 2.5 million others who had come into contact with them. Their simulation suggests that the most sensitive lateral flow rapid tests, although not as sensitive and specific as the PCR gold standard, could have detected nearly 90% of cases that led to an infected contact.
Masks and Safety Equipment
A recent study indicated that universal mask use (>95%) could save an additional 129,574 (85,284–170,867) lives from September 22, 2020 through the end of February 2021, or an additional 95,814 (60,731–133,077) lives assuming a lesser adoption of mask wearing (85%), when compared to the reference scenario.
