A new study led by Marshall University researcher M. Jeremiah Matson found that environmental conditions affect the stability of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human nasal mucus and sputum.
Matson, the lead author on a study published earlier this month as an early release in Emerging Infectious Diseases, the journal of the Centers for Disease Control and Prevention (CDC), is a student in the combined Doctor of Medicine and Doctor of Philosophy in Biomedical Research program at the Marshall University Joan C. Edwards School of Medicine.
SARS-CoV-2, the virus that causes the disease known as COVID-19, was found to be less stable at higher humidity and warmer temperatures. In the study, SARS-CoV-2 was mixed with human nasal mucus and sputum specimens, which were then exposed to three different sets of temperature and humidity for up to seven days. Samples were collected throughout the study and analyzed for the presence of infectious virus as well as viral RNA alone, which is not infectious. Viral RNA was consistently detectable throughout the seven-day study, while infectious virus was detectable for up to approximately 12-48 hours, depending on the environmental conditions.
