2. Basic knowledge of monkey acne

(1) Monkey acne tires

Monkey acne virus is a dual -chain DNA virus with a total length of about 197KB. It belongs to the genus of acne virus virus. It is one of the 4 viruses of human pathogenia in the acne virus (the remaining three are ceiling virus, acne seedlings and cattle acne Virus). There are two branches of monkey acne virus (West African branch and Congo basin branch). Among them, the mortality rate of West African branch is about 3.6%, and the mortality rate of the Congo basin can reach 10.6%[2]. The samples of monkey acne cases found in non -local popular regions since May 2022 have sequencing analysis results in West African branch.

Monkey acne virus is sensitive to thermal. It can be lively at 56 ° C for 30 minutes or 60 ° C for 10 minutes. UV and general disinfection agents can also be lived. It is sensitive to sodium hypochlorite, chlorine phenol, pentalaldehyde, formaldehyde, and polyetal formaldehyde.

(2) Monkey Acne Popularities

Monkey acne virus in nature mainly exists in Africa (African squirrels, tree squirrels, Gangbia kangaroos, sleeping mouse, etc.). Long -priests (monkeys, chimpanzees, people, etc.) are also infected after contacting rodents infected with monkey acne virus. Animals and patients with monkey acne virus are the source of this disease.

People are infected by contacting the respiratory tract secretions, lesions, blood, other body fluids, or being infected by infected animals infected by infection. People are mainly transmitted through close contact, and can also be transmitted through droplets during long -term contact, and items that contact virus pollution may also be infected. This time the monkey acne epidemic also found that most cases have homosexual behaviors before the onset, which may be mainly related to close contact and spread in sexual activities. At present, it is not possible to determine whether semen or vaginal secretions will be spread. Monkey acne virus can also be transmitted to the fetus from a pregnant woman through the placenta.

Those who have been vaccinated in the past have a certain degree of cross protection for monkey acne virus. People who have not vaccinated the ceiling vaccine (especially those born after 1981) are generally susceptible to monkey acne virus. (3) Clinical manifestations of patients with acne patients
