Coronavirus

The COVID-19 pandemic provides an opportunity for further evolution of the field of precision public health, as new tools and technologies begin to complement traditional medical and public health approaches to prevention and control. Despite challenges, at no time has precision public health been needed more than now.
A negative COVID-19 test does not mean recovery

Phase 1/2 study of COVID-19 RNA vaccine BNT162b1 in adults
MJ Mulligan et al, Nature, August 12, 2020
We report the available safety, tolerability, and immunogenicity data from an ongoing placebo-controlled, observer-blinded dose escalation study among 45 healthy adults, 18 to 55 years of age, randomized to receive 2 doses, separated by 21 days, of 10 µg, 30 µg, or 100 µg of BNT162b1, a lipid nanoparticle-formulated, nucleoside-modified mRNA vaccine.
Evidence is rapidly emerging on the effectiveness of tests for COVID-19 diagnosis and management, but important uncertainties about their effectiveness and most appropriate application remain. Estimates of diagnostic accuracy should be interpreted bearing in mind the absence of a definitive reference standard to diagnose or rule out COVID-19 infection.
Racial Disproportionality in Covid Clinical Trials
DB Chastain et al, NEJM, August 10, 2020
Lack of diversity in clinical trials may stem from long-standing medical distrust on the part of minority communities, but the problem may be compounded by cost (e.g., hidden costs for such requirements as fuel, parking, meals, and lodging), poor health literacy, lack of information, language barriers, limited accessibility, and implicit biases against minorities.
