• People can’t expect lifeguards to be present for every drowning victim, which makes it important to know what to look for, one expert says.
  • Experts say not to go into the water to save someone if you are not a good swimmer yourself because those drowning can inadvertently pull you under.
  • Swimming experts say there are tools people can use to prevent drownings, including water watcher cards and throw bags.

Children are most at risk for it, but drowning can happen to anyone.

In May, a four-year-old boy nearly drowned in his apartment complex pool before another resident came to help. The boy was underwater for more than three minutes.

And on Sunday, the body of 61-year-old “ER” actress Mary Mara was found in the St. Lawrence River near Cape Vincent, New York. Police said the preliminary investigation suggests she drowned while swimming.

Every year in the United States, there are an estimated 3,960 fatal unintentional drownings, including boating-related drownings, according to the Centers for Disease Control and Prevention. That’s about 11 drowning deaths per day.

Some demographics are at a higher risk to drown, like children ages 1 to 4 and males, who make up nearly 80% of people who die from drownings. Factors that might contribute to the gender disparity in drowning deaths could include males’ increased exposure to water, risk-taking behaviors and alcohol use, the CDC said on its website.

Drowning death counts vary by race, too, the CDC said.

Drowning death rates for American Indian or Alaska Native people ages 29 and younger are two times higher than the rates for white people.

Rates for Black people are 1½ times higher than the rates for white people. The risk is higher for Black children ages 5 to 9 and 10 to 14.

People with seizure disorders or certain medical conditions are more at-risk for drowning as well, the CDC said.
