Key result
High humidity extends rhinovirus surface survival to ~14 hours in broth versus nasal discharge.
Why the study?
The survival of human rhinovirus 14 on environmental surfaces under different relative humidity levels and suspending media was studied to understand virus infectivity loss.
Human rhinovirus 14 survival on nonporous surfaces is highly dependent on the suspending medium and relative humidity, with the shortest half-lives observed when suspended in human nasal discharge.

Variable surface survival by medium and humidity warrants targeted disinfection; leaves open real-world rhinovirus transmission risks.
Sattar et al. (1987) studied Human rhinovirus 14 survival on environmental surfaces. Relative humidity and suspending medium was evaluated on Virus infectivity loss and half-life. Survival of human rhinovirus 14 on nonporous surfaces was highest when suspended in tryptose phosphate broth at high relative humidity (half-life ~14 h) compared to mucin or nasal discharge.
