Monkey pox can persist in household environments, according to CDC study. The zoonotic monkey pox virus (MPXV), which is endemic to Africa, is typically transmitted through direct contact with an infected person or animal or through the inhalation of infected respiratory secretions.
Infection with MPXV often leads to the development of lesions with exudates that contain viable virions that can be shed during infection. As compared to other enveloped viruses, MPXV virions are more tightly bound with the fibrin matrices of the scab/crust, thereby allowing for them to persist within the environment for longer periods.
A recent study conducted by the United States Centers for Disease Control and Prevention (CDC) and published in the journal Emerging Infectious Diseases assessed the viability and viral load of MPXV on household objects and surfaces.
Samples were collected from frequently used objects in the household of an individual who had been infected with MPXV.
This sampling was conducted 15 days after the infected individual had left their home to be admitted to the hospital.
These samples were then incubated to allow for virus isolation and the detection of viable viruses. Importantly, any potential contamination with bacteria or fungi was prevented by treating all incubated samples with penicillin/streptomycin, amphotericin B, and gentamicin.
