ST. LOUIS -- The YMCA's Camp Lakewood outside of Potosi, Mo., has been shut down after about 70 campers and counselors got sick in the past week.

Camp Lakewood spokeswoman Melissa Gilliam said about 1,000 campers and staff have been at the camp in the last week. Most of them are from the St. Louis area and were returning home. She said symptoms include nausea, vomiting and diarrhea.

Health officials and doctors who have been working with the camp do not suspect swine flu. The camp is closed through Saturday.
