The monkeypox virus can linger on many common household objects, though it’s not yet clear if that can spread the infection, according to a new government study.
Two monkeypox patients sharing a home said they disinfected surfaces, washed their hands several times a day and showered regularly. Researchers still found the virus on 70% of high-contact areas 20 days after their symptoms began, including on couches, blankets, a coffee machine, computer mouse and light switch, the U.S. Centers for Disease Control and Prevention said.
However, no live virus was detected on any of the items or surfaces, suggesting the risk infections could spread is low. The CDC said cleaning and disinfection practices may have limited the amount of contamination in the home.
The study sheds new light on the behavior of the monkeypox virus while also raising questions. Monkeypox primarily spreads through direct contact with lesions or respiratory secretions during sustained close contact with someone who is sick. More than 90% of monkeypox cases in the U.S. were associated with recent male-to-male sexual contact, according to a different CDC study.
The virus can also spread through fluids or objects used by an infected person, but it’s not yet clear how much some surface contamination contributes to indirect transmission of the virus, according to the study.
People visiting the home of someone with monkeypox should still protect themselves “by wearing a well-fitting mask, avoiding touching possibly contaminated surfaces, maintaining appropriate hand hygiene, avoiding sharing eating utensils, clothing, bedding, or towels and following home disinfection recommendations,” the CDC says.
Both patients had cases of monkeypox that were reported in May, according to the study. One of the people had lesions on the genitals, hands, chest, lips and scalp, while the other had lesions on the foot, leg and finger. They were both sick for about a month, according the report.
