With the recent spread of the disease Monkeypox, information on the issue is limited and pressing. An increasing number of cities around the world are declaring the spread of this disease a public health crisis, and people want to know what they can do to protect themselves. In an obligational report, the CDC addresses these new concerns and accounts how exactly this disease is able to spread: Monkeypox virus is a completely different virus than the viruses that cause COVID-19 or measles. It is not known to linger in the air and is not transmitted during short periods of shared airspace. Monkeypox spreads through direct contact with body fluids or sores on the body of someone who has monkeypox, or with direct contact with materials that have touched body fluids

In an obligational report, the CDC addresses these new concerns and accounts how exactly this disease is able to spread:

Monkeypox virus is a completely different virus than the viruses that cause COVID-19 or measles. It is not known to linger in the air and is not transmitted during short periods of shared airspace. Monkeypox spreads through direct contact with body fluids or sores on the body of someone who has monkeypox, or with direct contact with materials that have touched body fluids or sores, such as clothing or linens. It may also spread through respiratory secretions when people have close, face-to-face contact.

In the current monkeypox outbreak, we know that those with disease generally describe close, sustained physical contact with other people who are infected with the virus. We continue to study other possible modes of transmission, such as through semen.

Prior studies of monkeypox outbreaks show that spread of monkeypox virus by respiratory secretions appears uncommon. Most cases of monkeypox report close contact with an infectious person. While we do not know with certainty what role direct physical contact has versus the role of respiratory secretions, in instances where people who have monkeypox have travelled on airplanes, no known cases of monkeypox occurred in people seated around them, even on long international flights.

There are important differences between airborne transmission and transmission via respiratory secretions. Airborne transmission occurs when small virus particles become suspended in the air and can stay there for periods of time. These particles can spread on air currents, or sometimes even infect people who enter a room after the infected person has left. In contrast, monkeypox may be found in droplets like saliva or respiratory secretions that drop out of the air quickly. Long range (e.g., airborne) transmission of monkeypox has not been reported.

CDC currently recommends that people infected with monkeypox wear a mask if they must be around others in their homes if close, face-to-face contact is likely. In a healthcare setting, a patient with suspected or confirmed monkeypox infection should be placed in a single-person room; special air handling is not required. Any procedures likely to spread oral secretions (such as intubation and extubation) should be performed in an airborne infection isolation room.

Examples where monkeypox can spread:

No: Casual conversations. Walking by someone with monkeypox in a grocery store. Touching items like doorknobs.
Yes: Direct skin-skin contact with rash lesions. Sexual/intimate contact. Kissing while a person is infected.
Yes: Living in a house and sharing a bed with someone. Sharing towels or unwashed clothing.
Yes: Respiratory secretions through face-to-face interactions (the type that mainly happen when living with someone or caring for someone who has monkeypox).
Maybe/Still learning: Contact with semen or vaginal fluids.
Unknown/Still learning: Contact with people who are infected with monkeypox but have no symptoms (We think people with symptoms are most likely associated with spread, but some people may have very mild illness and not know they are infected).
