Which group is at the highest risk of developing RWIs?

Children under 5 are considered the group at the highest risk of developing recreational water illnesses (RWIs) due to several factors. Young children often have underdeveloped immune systems, making them more susceptible to infections and illnesses that can arise from waterborne pathogens. Additionally, children in this age group are more likely to ingest water while swimming, due to their playfulness and tendency to accidentally swallow water.

Moreover, they may also be less aware of hygiene practices such as not swallowing pool water or washing their hands after using the restroom. This can contribute to a higher likelihood of spreading germs, which can lead to various RWIs. In aquatic settings like swimming pools, water can become contaminated, increasing the risk for this age group, especially if proper safety and hygiene protocols are not observed.

While other groups, such as adults or pregnant women, might also face risks, the specific vulnerabilities of young children make them particularly susceptible to the types of infections associated with RWIs.
