We found that environmental conditions affect the stability of severe acute respiratory syndrome coronavirus 2 in nasal mucus and sputum. The virus is more stable at low-temperature and low-humidity conditions, whereas warmer temperature and higher humidity shortened half-life. Although infectious virus was undetectable after 48 hours, viral RNA remained detectable for 7 days.
我们发现环境条件会影响严重急性呼吸综合征冠状病毒 2 在鼻腔黏液和痰液中的稳定性。病毒在低温和低湿度条件下更稳定,而较高的温度和湿度会缩短半衰期。虽然在 48 小时后无法检测到有感染性的病毒,但病毒 RNA 仍可在 7 天内被检测到。
