Infectivity of airborne SARS-CoV-2 could decrease by 90% within 20 minutes of exhalation, new laboratory study finds
The SARS-CoV-2 virus can lose 90% of infectivity when in aerosol particles within 20 minutes, according to new University of Bristol findings. The study, published in the journal of the Proceedings of the National Academy of Sciences (PNAS), is the first to investigate the decrease in infectivity of SARS-CoV-2 in aerosol particles over periods from seconds to a few minutes. The aim of the study was to explore the process that could change viral infectivity over short timescales following exhalation. (Source: University of Bristol news)

Dogs Can Sniff Out COVID-19 and Signs of Long COVID, Studies Suggest
A dog’s sense of smell is thousands of times stronger than a human’s. Their superior snoots are why canines are used in law enforcement; once they’re trained to detect certain scents, like narcotics and explosives, they can pick up traces that human noses could never notice. The same skill translates to medicine.
