SIOUX FALLS, S.D. (KELO) — The South Dakota Department of Health (DOH) says a second case of measles has been detected in the state in 2025, this one also in West River.
The DOH sent the announcement out at 4:48 p.m. on Friday, informing the public that there was potential of a measles exposure at two locations in Pennington County.
These were the Sam’s Club at 925 Eglin St in Rapid City on June 1 from noon to 6:00 p.m., and the Dakota Premier Medical Clinic at 2006 Mt Rushmore Rd in Rapid City on June 2 from 11:15 a.m. to 3:45 p.m.
The DOH is advising any person who visited those locations during the mentioned time frames that they may have been exposed to measles, and are asked to self-monitor for symptoms of measles for 21 days after the exposure date.
Measles symptoms appear in two stages. In the first stage, the individual may have a runny nose, cough, and a slight fever. The eyes may become reddened and sensitive to light while the fever consistently rises each day. The second stage begins on the third to seventh day of symptoms and consists of a temperature of 103-105°F, and a red blotchy rash lasting for four to seven days. The rash usually begins on the face and then spreads down to the trunk and out to the arms and legs.
Information from the DOH
“We are sharing this information to help individuals who may have been exposed take steps to protect their health,” said State Epidemiologist Joshua Clayton. “Any South Dakotan who lack immunity from vaccination or past infection can get the MMR vaccine to prevent measles infection and its complications.”
South Dakota’s first measles case of 2025 was reported on June 2, and was identified in a man in Meade County who developed the infection after traveling internationally.
That man had visited the following locations, where people who may have been exposed are also asked to self-monitor:
- Rapid City Medical Center Urgent Care waiting room (2820 Mt Rushmore Road, Rapid City, SD
- May 28, 2025, from 7:15 am to 10 am MT
- Monument Health Sturgis Urgent Care waiting room (2140 Junction Ave, Sturgis, SD)
- May 29, 2025, from 9:45 am to 3 pm MT
