The Department of Health has reported the first measles case in South Dakota. Community members may have been exposed to the virus at two locations: Rapid City Medical Center Urgent Care on May 28, 2025, and Monument Health Sturgis Urgent Care on May 29, 2025.
Measles symptoms manifest in two stages. Initially, individuals may experience a runny nose, cough, slight fever, reddened eyes, and light sensitivity. In the second stage, which begins between the third and seventh day of symptoms, patients may develop a high fever ranging from 103-105°F and a red blotchy rash that lasts four to seven days.
Dr. Joshua Clayton, state epidemiologist, stated: “Measles is a highly contagious viral disease and spreads through the air from an infected person.” He emphasized that those without immunity are at significant risk if they come into contact with an infected individual.
The best protection against measles is vaccination. Immunity can be conferred by birth before 1957, receiving one or two doses of the MMR vaccine depending on age and risk factors, presence of measles antibodies shown by lab tests, or previous infection confirmed by lab tests. The MMR vaccine is typically administered to children at 12-15 months of age with a second dose given between ages four to six. It is highly effective in preventing infection and generally provides lifelong immunity after two doses.
Further information about measles can be accessed on the Department of Health website where fact sheets and resources for healthcare providers are available.
The Department of Health remains committed to its mission of protecting and improving health for all residents of South Dakota by promoting wellness and ensuring access to quality healthcare services.
