About Monkeypox (MPV)

Initial outbreaks of reported monkeypox (MPV) cases in May of 2022 were seen in Europe and first reported case in the United State (Massachusetts) were identified where the infected individual had not traveled to Africa where previous exposed monkeypox outbreaks were identified. Some of the outbreaks have patients who identify as gay, bisexual, or other same gender loving men. These outbreaks are currently under investigation and more information is expected in the future. Therefore, health care providers in Illinois should be alert for any suspect cases, even if the patient has not traveled but has an illness suspected to be MPV. These cases should be promptly reported to their local health department. Requests for testing should be made through the local health department.

MPV is rare and does not spread easily between people typically without close contact like skin-to-skin or face-to-face. Data currently show transmission is higher among people in close sexual networks, however, anyone in close contact like face-to-face (such as prolong hugging, cuddling, kissing) or skin-to-skin (such as prolong body contact) to any infected person may get the infection.

Monkeypox or MPV as it’s called in the latest development of this rare disease caused by infection with the monkeypox virus. Monkeypox virus belongs to the Orthopoxvirus genus in the family Poxviridae. Monkeypox is not related to chickenpox.

First discovered in monkeys with pox-like disease in 1958. Despite being named “monkeypox”, the source of the disease remains unknown. However, African rodents and non-human primates (like monkeys) may harbor the virus and infect people.

The first known human case of monkeypox was identified in 1970. Monkeypox can be found in animals (African rodents, monkeys, and other primates) and usually encountered in villages in west and central Africa. Historically, persons in Illinois could become infected by traveling to west and central Africa and being exposed to people or animals with the disease. One human outbreak in the U.S. in 2003 occurred when African rodents came in contact with pet prairie dogs at an Illinois animal vendor. Some persons in contact with the infected prairie dogs developed monkeypox, including 10 Illinois residents.

Monkeypox (MPV) is in the orthopox virus family, which includes cowpox and smallpox. Smallpox is no longer circulating in the world and was declared eradicated by the World Health Organization in 1980. Symptoms of monkeypox are milder than the symptoms of smallpox. The main difference between smallpox and monkeypox is that monkeypox causes lymph nodes to swell while smallpox does not. The incubation period for monkeypox is usually 7-14 days but can range from 5-21 days.

• Fever
• Headache
• Muscle aches
• Backache
• Swollen lymph nodes
• Chills
• Exhaustion

Within 1 to 3 days (sometimes longer) after the appearance of fever, the patient develops a rash, often beginning on the face and then spreading to other parts of the body or near certain areas like genitals, anus (butt), hands, feet, chest, or face. These sores can look like pimples and may be painful or itchy. They can be inside the body, including mouth, anus, or vagina. Note that a person is infectious the moment any of the above sign and symptoms start to appear.

The illness typically lasts for 2-4 weeks.

Monkeypox (MPV) may spread in different ways. The virus may spread from close contact like skin-to-skin or face-to-face through:

• Direct contact with infected skin rash, lesions, scabs, or body fluids
• Respiratory droplets during extended face-to-face contact, or during intimate physical contact, such as kissing, cuddling, or sex
  
• Contact with contaminated materials or objects (like clothing, towels, or linens) previously touched by infectious rash or body fluids
  
• Pregnant people may spread the virus to their fetus through the placenta
  

Individuals are infectious as soon as signs and symptoms appear.

People may get MPV from infected animals, either by being scratched or bitten by the infected animal or by preparing or eating meat or using products from an infected animal.
