Child deaths by drowning is also a problem in Vietnam
Swimming skills save lives

Sadly, there are too many examples of people not knowing how to swim in Vietnam. On June 1 – International Children’s Day – five children drowned in two separate incidents. In April, five drowned after playing in a river near their school.

In 2020, five youngsters aged two to 13 drowned, and the year before that, five 14-year-olds perished after taking an unsupervised dip in a reservoir during a school picnic.

Child drownings have declined by an average of 100 each year in Vietnam. But the World Health Organization cites a 2020 estimate which says more than 2,000 children under the age of 16 drown each year in the country, making drowning one of the leading causes of death for this age group.

Calls to address the issue resurface each time local media reports the number of children drowning.

Globally, drowning is the third-leading cause of death by unintentional injury with children among the most at risk. But it did not receive high-level international attention until 2014, when the WHO published its first global report on drowning.

Vietnamese Prime Minister Pham Minh Chinh in 2021 approved a national programme on preventing child injury and death, aiming to reduce child drowning fatalities by 20 per cent in eight years.

There were lots of staff on tourist boats in Sihanoukville that couldn't swim!
If a customer went in the water and got into trouble, they would throw out a ring and hope for the best.
