Critical Appraisal of COVID-19 Research

LitCovid Database (NLM)

LitCovid is a curated literature hub for tracking up-to-date scientific information about the 2019 novel Coronavirus. This database is produced by the National Library of Medicine/NCBI BioNLP Research Group. Click topics below to access current results for expert search results.

Some LitCovid search tips:

use AND between terms to narrow search results (e.g. lung AND cancer)
use OR between terms to broaden search results (e.g. pediatric OR child OR adolescent)
the database will automatically truncate and mapping for some words (e.g. pediatric will include pediatrics, infants, etc.) but not all
to force an exact phrase use quotations (e.g. "lung cancer"); use with caution (may exclude relevant articles)

To ensure that people with coronavirus disease 2019 (COVID-19) get the care they need, it would help if a simple blood test could predict early on which patients are most likely to progress to severe and life-threatening illness—and which are more likely to recover without much need for medical intervention. Now, researchers have provided some of the first evidence that such a test might be possible.

Scientists and engineers with many years of collective research experience related to indoor air quality, aerosol science, aerosol disease transmission, and engineered control systems for aerosols. Our contributors are active researchers investigating aerosol transmission of COVID-19 (see e.g. 1, 2, 3, and 4). Five of us were speakers at the recent Workshop on Airborne Transmission of COVID-19, organized by the US National Academies of Sciences, Engineering, and Medicine (the highest level scientific organization in the US). Three of us are members of a COVID-19 WHO expert group.

Let’s face it, there is a reason why hospitals with designated COVID-19 areas require everyone to wear an N95 respirator mask, as well as eye goggles. That’s because we know that this virus has the potential for airborne transmission. During normal breathing and speech, tiny particles are emitted mainly from the mouth. These particles can range in size, with the smallest being less than a micron (1 um), and the biggest being over 500 um in diameter.
