First Probable Case of Monkeypox Reported in DuPage County, Third in Illinois: Officials

The first probable case of monkeypox has been detected in DuPage County, health officials announced Friday, which would make it the third reported in Illinois.

The case was found in a man who had traveled internationally in the past month to a country which has also reported monkeypox infections recently, the DuPage County Health Department said.

Initial testing was completed with the Illinois Department of Public Health and now proceeds to confirmatory testing at the U.S. Center for Disease Control and Prevention.

"Based on initial epidemiologic characteristics and the positive orthopoxvirus result at IDPH, health officials consider this a probable monkeypox infection," DCHD said in a statement.

Health officials said the case remains isolated and there's no indication of a greater risk for spread "as monkeypox does not spread as easily as the COVID-19 virus."

The latest case comes amid a rash of cases bring reported in the U.S. and several other countries, health officials announced Thursday.

Monkeypox is a rare, but potentially serious viral illness, which often begins with flu-like symptoms and swelling of the lymph nodes, and progresses to a rash on the face and body, health experts said. It was first observed in Africa in 1970, and is usually found in western and central portions of the continent.

The CDC is on alert after cases of the virus were reported in several countries that typically do not report monkeypox cases, including the U.S.

As of Friday, the CDC has reported 49 confirmed cases across multiple states including Arizona, California, Colorado, District of Columbia, Florida, Georgia, Hawaii, Massachusetts, New York, Oklahoma, Pennsylvania, Rhode Island, Texas, Utah, Virginia, and Washington.

"Usually, in a normal year, we will see a few cases mostly in Western Africa that are related to animals," Chicago Department of Public Health Commissioner Dr. Allison Arwady said. "There are animals that can carry it and we'll see, you know, a few dozen cases that people can get infected just from just from being in contact with animals. The reason there's been more attention is that at this point, there's been somewhere between 100 cases that have been identified that are not connected to the typical way that we see monkeypox."

The virus comes from the same family as smallpox, and the World Health Organization has also been urging individuals to be on the look out after nearly 200 confirmed or suspected cases were reported in at least 12 western countries. According to officials, the majority of those cases have occurred in Portugal, Spain and the United Kingdom.

“What makes this a little different is the number of cases, and the countries that are affected by this,” Dr. Irfan Hafiz of Northwestern Medicine’s McHenry and Huntley Hospitals, said.

The CDC said that “cases include people who self-identify as men who have had sex with men,” but emphasized that anyone can contract the illness through prolonged contact.

We already have vaccines and treatments approved for monkeypox

Hafiz, an infectious disease specialist, said the virus causes symptoms that are similar to several maladies, including chickenpox or smallpox.

“It can, to the layperson, look like chickenpox or warts,” he said. “But these (sores) tend to be in exposed areas.”

Health experts also said the illness can be confused with a sexually transmitted infection like syphilis or herpes, or with varicella zoster virus.

Federal health officials are urging doctors in the U.S. to "consider a diagnosis of monkeypox in people who present with a consistent rash, especially if they meet any of the following criteria:

  • Had contact with someone who had a rash that looks like monkeypox or someone who was diagnosed with confirmed or probable monkeypox
  • Had skin-to-skin-contact with someone in a social network experiencing monkeypox activity; this includes men who have sex with men who meet partners through an online website, digital application (app), or social event (e.g., a bar or party)
  • Traveled outside the US to a country with confirmed cases of monkeypox or where monkeypox activity has been ongoing
  • Had contact with a dead or live wild animal or exotic pet that exists only in Africa or used a product derived from such animals (e.g., game meat, creams, lotions, powders, etc.).

The virus is rarely lethal, with symptoms ranging from fever, aches and rashes all over the body.

"Suspected cases may present with early flu-like symptoms and progress to lesions that may begin on one site on the body and spread to other parts," the Chicago Department of Public Health stated.

CDPH said person-to-person transmission is possible through "close physical contact with monkeypox sores, items that have been contaminated with fluids or sores (clothing, bedding, etc.), or through respiratory droplets following prolonged face-to-face contact."

“It’s not just your casual handshake,” Hafiz said. “(Contact must be) longer, more pronounced. It is not technically a sexually transmitted disease, but it involves close contact.”

“It takes prolonged (contact), not minutes,” NBC News Medical Contributor Dr. Kavita Patel added. “(It can also involve) body fluids or lesions.”

Infections typically last between two and four weeks, CDPH said.

Health officials said anyone with a "new or unexplained rash, sores, or symptoms, or have a confirmed exposure" should visit their healthcare provider and "avoid sex or being intimate with anyone until they have been seen."
