Stability and inactivation of monkeypox virus on inanimate surfaces.

The spread of non-zoonotic monkeypox virus (MPXV) infections necessitates the re-evaluation of hygiene measures. To date, only limited data is available on MPXV surface stability. Here, we evaluate the stability of infectious MPXV on stainless steel stored at different temperatures, while using different interfering substances to mimic environmental contamination. MPXV persistence increased with decreasing temperature. Additionally, we were able to show that MPXV could efficiently be inactivated by alcohol- and aldehyde-based surface disinfectants. These findings underline the stability of MPXV on inanimate surfaces and supports the recommendations to use alcohol-based disinfectants as prevention measure or in outbreak situations.
