Stability of Monkeypox Virus in Body Fluids and Wastewater. | LitMetric

AI Article Synopsis

  • An outbreak of human mpox infection in nonendemic countries is largely due to transmission through body fluids or skin-to-skin contact during sexual activity.
  • Researchers evaluated how stable the monkeypox virus (MPXV) is in different environments and body fluids, finding it decayed faster at higher temperatures and varied by the medium.
  • Effective decontamination techniques included chlorination at higher concentrations, and testing wastewater for infectious MPXV could enhance surveillance efforts when a significant amount of viral DNA is present.*

Article Abstract

An outbreak of human mpox infection in nonendemic countries appears to have been driven largely by transmission through body fluids or skin-to-skin contact during sexual activity. We evaluated the stability of monkeypox virus (MPXV) in different environments and specific body fluids and tested the effectiveness of decontamination methodologies. MPXV decayed faster at higher temperatures, and rates varied considerably depending on the medium in which virus was suspended, both in solution and on surfaces. More proteinaceous fluids supported greater persistence. Chlorination was an effective decontamination technique, but only at higher concentrations. Wastewater was more difficult to decontaminate than plain deionized water; testing for infectious MPXV could be a helpful addition to PCR-based wastewater surveillance when high levels of viral DNA are detected. Our findings suggest that, because virus stability is sufficient to support environmental MPXV transmission in healthcare settings, exposure and dose-response will be limiting factors for those transmission routes.
