Centers for Disease Control and Prevention, CDPHE, and local public health officials are currently monitoring cases of monkeypox in Colorado. 

Monkeypox is a virus in the orthopox family of viruses. Monkeypox is rare, but it can be serious for people who get it.
Monkeypox can spread from person to person when someone who has monkeypox has close contact with someone else. Close contact can mean physical contact with the sores, bumps, or lesions of someone who has monkeypox. Close contact includes sex. Monkeypox can also spread through touching the bed linens or clothing of someone who has monkeypox. Monkeypox can also live on other surfaces for some time. 

Recent cases in the United States have been infected through person-to-person contact. Brief interactions without physical contact are unlikely to result in getting the virus.

Monkeypox has recently been spreading in parts of the United States, Canada, Europe, and Australia. It is endemic in central and west Africa. Recent data suggest people who have recently traveled to a country where monkeypox has been reported or men who have sex with other men are at heightened risk.

The type of monkeypox spreading in the United States is rarely deadly and has a fatality rate of less than 1%. In fact, in most cases, monkeypox will resolve on its own. Symptoms of monkeypox may begin with flu-like symptoms that can include fever, headache, muscle aches, swollen lymph nodes, and exhaustion. Typically, a rash or skin bumps develop within one to three days after the onset of fever, often beginning on the face then spreading to other parts of the body. 

Monkeypox can look like syphilis, herpes, blisters, or even acne, so be sure to get checked out if you develop a new rash or bumps. In recent cases, additional symptoms have not always occurred before the rash or bumps if they have occurred at all. The incubation period for monkeypox is usually seven to 14 days but can range from less than five to 21 days. Most people recover within two to four weeks. 

Colorado case numbers are listed below according to the month in which a person first presented with monkeypox symptoms. Case counts for all time periods may change as CDPHE identifies more cases. This data is updated as of 10 a.m. August 9, 2022, and will update Tuesday-Friday at 10 a.m.

Where to get tested for monkeypox
People who are experiencing symptoms of monkeypox or think they have been exposed to monkeypox should contact a health care provider to discuss testing. Many providers can now submit specimens through commercial laboratory networks such as Aegis Science, Labcorp, Mayo Clinic Laboratories, Quest Diagnostics, and Sonic Healthcare.
If you do not have a health care provider, or do not have insurance, the following locations have monkeypox testing available for people who have a rash they suspect may be monkeypox. Appointments are limited — call the phone number listed to ask about available appointments. If you have a rash or sores, cover them with long sleeves, pants, or a bandage. Wear a well-fitting mask over your nose and mouth during your appointment. Patients can take this document with them to their medical visit.
We will add more locations to this page as they become available.

Vaccine information

Some people who have been recently exposed to monkeypox should get a vaccine called Jynneos. The FDA has fully approved this vaccine. Colorado currently has an extremely limited supply of the vaccine from the federal government.
Getting vaccinated lowers your chance of getting monkeypox if you may have been exposed. The sooner an exposed person gets the vaccine, the better. The vaccine can also reduce the severity of your symptoms if you do get sick later on. People who already have symptoms of monkeypox (fever, rash, etc.) should not get vaccinated.

CDPHE vaccine clinics

CDPHE is hosting a limited number of free vaccine clinics for eligible Coloradans who meet the criteria below. Request a vaccine appointment using this form. Appointment requests will be made available based on our extremely limited vaccine allotment from the federal government.
