Dry drowning usually happens soon after exiting the water, but with secondary drowning, there can be a delay of up to 24 hours before the person shows signs of distress. Both can cause trouble breathing and, in worst-case scenarios, death.
Who is at risk. CHILDREN: Children ages 1 to 4 have the highest drowning rates and about one in five people who die from drowning are children 14 and younger. In 2013, there were 11 drowning deaths in children 14 years and under in Washington. Many drownings in young children occur in bathtubs, buckets and swimming pools; although drowning rates have declined, drowning is still the 2nd leading cause of death in children ages 1-14.
