Stability of Monkeypox Virus on Commonly Contacted Surfaces in Clinical Settings

1

Monkeypox virus (MPXV) can persist on various surfaces, contributing to fomite-mediated transmission in healthcare environments.
2

MPXV stability is influenced by surface type and temperature, with nonporous surfaces supporting longer virus viability.
3

Infectious MPXV was detected for up to 21 days on intravenous tubing and nitrile gloves at 4 °C.
4

Porous materials like cotton showed rapid loss of infectivity, especially at room temperature.
5

Viral DNA presence does not correlate with infectious virus, indicating molecular assays may overestimate transmission risks.
