Metrex Research and Development staff have, like you, noted the outbreak of Monkeypox infections outside of endemic countries normally associated with this viral disease1,2. This communication addresses applicability of Metrex Research products as infection prevention tools in the environment of care when a risk of monkeypox to patients, staff and others is determined.
The Monkeypox virus is a member of the poxviridae family and classified in the orthopoxvirus genus, which includes Vaccinia (cowpox) and Variola (smallpox) virus. Orthopoxvirus particles are large, enveloped double stranded DNA viruses. They are most commonly transmitted by human-animal contact and human-to-human contact. Current evidence suggests that the mucosal membranes are particularly susceptible points of entry for the monkeypox virus to infect the host. Transmission via contaminated objects (fomites) is also suspected
A study on Vaccinia virus, also a member of the genus orthopoxvirus, indicated survival of the virus, measured as infectivity, on common environmental surfaces up to 56 days in low temperatures and relative humidity3 . The same study also found that no Vaccinia virus was detectable on the same surfaces at room temperatures and higher humidity at seven days with substantial drops at three days3 . Monkeypox virus is also not thought to survive for long periods on hard, dry surfaces due to its envelope which is needed for infection and its relatively large size: thought to be similar to vaccinia virus studied.
Although hard surface (fomite) transmission is not the most common route of Monkeypox virus transmission, there is evidence that close contact with shared bedclothes and shared use eating utensils (e.g. not washed between uses during a meal) have transmitted the virus between humans4,5. Hard surface disinfection of surfaces which may directly or indirectly contact mucosa is recommended to reduce Monkeypox transmission, a practice aligned with current environmental hygiene practices in most environments of care.
Metrex Hard Surface Disinfectants with Effectiveness Against Monkeypox Virus
Different public health advisories are employed in different regions internationally. Metrex Research wants to assure healthcare professionals use the infection prevention tools we offer in a manner aligned with the regulations and availability in your region. The following table lists Metrex disinfectant options, aligned with current recommendations from public health sources, when a risk of monkeypox transmission exists in your facility. Please consult local public health authorities for the latest information regarding outbreaks in your area and follow precautions, including use of personal protective equipment, indicated if you have a suspected monkeypox case in your facility.
