vomiting diarrhea after snorkeling

17:30 Jul 18 2020 San Diego, La Jolla Cove marine reserve

We went snorkeling at La Jolla Cove and later that evening my son (10 years old) had vomiting and diarrhea on and off for about 12 hours. The whole family had eaten the exact same food all day, and with COVID-19 we have not been around anyone to catch a stomach bug. I can only think it was the water. The tide was high and the water was especially cloudy, with lots of sea lions in close proximity.
