TL;DR: COVID-19 patients recruited in Beijing exhaled millions of SARS-CoV-2 RNA copies into the air per hour, and exhaled breath samples had the highest positive rate, suggesting breath emission may play an important role in the CO VID-19 transmission.

TL;DR: Wang et al. as mentioned in this paper showed that the spread of SARS-Cov-2 was reduced by increasing ambient ozone concentration level from 48.83 to 94.67μg/m3 and decreasing relative humidity from 23.33 to 82.67% (p-value ǫ= 0.002) and temperature from −13.17 to 19°C)

TL;DR: While there is a critical need for strengthening hospital discharge standards in preventing re-emergence of COVID-19 spread, use of breath sample as a supplement specimen could further guard the hospital discharge to ensure the safety of the public and minimize the pandemic re- emergence risk.

TL;DR: The results imply that airborne transmission of SARS-CoV-2 plays a major role in COVID-19 spread, especially during the early stages of the disease.

TL;DR: In this paper, the highest positive rate (26.9%, n=52), followed by surface swabs (5.4, n=242), and air samples (3.8), n=26).
