The Minnesota Department of Health is investigating an outbreak of cryptosporidiosis after three people who visited Shades of Sherwood Campground in Zumbrota fell ill.
The MDH asks that anyone who visited the Shades of Sherwood campground call them at 651-201-5794 to better assess the source of infection and determine whether there is further risk.
According to a press release, “this step is especially important in this investigation because MDH investigators have been unable to get key information from the facility itself.”
Cryptosporidiosis is a diarrheal disease from a parasite called cryptosporidium.
The parasite spreads through contact with fecal matter from infected people or areas. It is the most common cause of waterborne illness in the U.S., as it survives outside the body for long periods of time and is resistant to chlorine.
The symptoms of cryptosporidiosis include watery diarrhea, stomach cramps, vomiting, weight loss, and a low fever. Symptoms generally appear about a week after exposure, but can arrive in as little as two or as many as 14 days.
Approximately 350-450 cases of cryptosporidiosis are diagnosed in Minnesota each year.
The MDH encourages anyone with symptoms of cryptosporidiosis — especially if they have visited Shades of Sherwood — to contact their doctor.
Most people recover within a week or two, but between 10 and 15 percent of people with cryptosporidiosis require hospitalization.
One of the infected people located by the MDH required hospitalization. One was also infected with E. coli, a bacterium that is also commonly encountered through contact with mammalian fecal matter.
Additionally, people who are infected with Cryptosporidium will continue to shed the parasite in their stool for around two weeks after symptoms end. The MDH cautions those with symptoms of cryptosporidiosis against swimming while sick and for two weeks after the symptoms go away.
