Swimming and boating at Blue Lake Regional Park remain closed today while public health officials continue to investigate reports of illness from people who visited over the weekend.
So far, interviews with park visitors support the theory that the outbreak was caused by something similar to norovirus – a highly contagious sickness, characterized by vomiting and diarrhea that last for a day or two.
Additional interviews and stool samples are expected to provide more information by the end of the week.
The Multnomah County Health Department and Metro are working together to determine when it’s safe to reopen the lake, with support from public health officials in Clackamas, Washington and Clark counties and the State of Oregon.
