The more you know about microbiology, the harder it is to go swimming. The ocean not only has the odd macrobiotic sting ray and shark but various sorts of bacteria, dinoflagellates and viruses. That's in a healthy ocean.
As Dr. Michael Beach (his real name), an epidemiologist in the parasitic disease section of the Centers for Disease Control and Prevention in Atlanta, said, "A lot of these bugs just live in the wild and we get in their way."
Dr. Beach is involved in the healthy swimming campaign for the agency. The seashore and rivers, ponds and lakes are part of its concern, because they can certainly contain health hazards, even if they are not polluted. But the current focus is on pools and a parasite called cryptosporidium.
