Tend to get sick when the air is dry? New research helps explain why
Recent research from CU Boulder may have finally revealed why humans tend to get sick from airborne viral diseases more often in drier environments. Published in December in PNAS-Nexus, the study found that airborne particles carrying a mammalian coronavirus closely related to the virus which causes COVID-19 remain infectious for twice as long in drier air, in part because the saliva emitted with them serves as a protective barrier around the virus, especially at low humidity levels.
