Jeremiah	Effect of Environmental Conditions on SARS-CoV-2 Stability in Human Nasal Mucus and Sputum	2020-09-17		.txt	text/plain	1418	82	52	We found that environmental conditions affect the stability of severe acute respiratory syndrome coronavirus 2 in nasal mucus and sputum. We describe SARS-CoV-2 stability in human nasal mucus and sputum under different environmental conditions. The t 1/2 we report here for SARS-CoV-2 in surface nasal mucus and sputum at 21°C/40% (Table) is considerably shorter than what we found in culture media under similar conditions (t 1/2 6.8 [95% CI 5.6-8.2] hours) (3). Nevertheless, with our experimental protocol and initial titer, we predicted that SARS-CoV-2 would remain infectious in nasal mucus and sputum on surfaces for >10-12 hours even in warm, humid conditions. In addition, reduced surface stability of SARS-CoV-2 in human nasal mucus and sputum in warmer and more humid conditions might result in decreased virus transmission, and climatic influence on SARS-CoV-2 transmission rates might eventually drive seasonal outbreak dynamics in a postpandemic period (7) , similar to other respiratory viruses (e.g., influenza A virus or human coronavirus OC43).	./cache/cord-277873-4819g00y.txt	./txt/cord-277873-4819g00y.txt
