New Crater Lake Sickness Blamed on First Outbreak
August 16, 1975
Crater Lake, Ore. (AP) – A federal health officer said yesterday that water at Crater Lake National Park apparently is not responsible for the new outbreak of a gastrointestinal disease.
Dr. Mark Rosenberg, an epidemic intelligence service officer from the Center for Disease Control in Atlanta, Ga., said the 14 new cases reported Thursday appear to be secondary infections contracted from those who had the disease earlier.
In July, hundreds of park employes and visitors who drank water from the park’s contaminated system were stricken.
Rosenberg said there is no evidence that this round of illness came from Munson Spring, the apparent source of the problem in July.
