On Aug. 1, Gov. J.B. Pritzker declared the spreading monkeypox virus to be a statewide public health emergency.

Pritzker’s declaration, which marks the state as a monkeypox “disaster area,” will allow public health officials to more aggressively respond to the outbreak, the governor’s office said.

The smallpox-related monkeypox virus was first detected in humans in 1970 and is endemic to parts of west and central Africa. The illness often begins with flu-like symptoms and swelling of the lymph nodes before progressing to painful, distinct, large rashes throughout the body that look like pimples or blisters. Monkeypox symptoms can last up to four weeks.
