Which group of people is most at risk from health effects of mould exposure?

Young children are particularly susceptible to the health effects of mould exposure due to several factors. Their immune systems are still developing, making them more vulnerable to infections and respiratory issues. Additionally, children typically have higher respiratory rates than adults, which means they breathe in more air—and therefore, more potential mould spores—relative to their body size. This increased exposure can lead to a higher risk of adverse health effects, such as asthma, allergies, and other respiratory complications.

In contrast, while healthy adults and older adults without medical histories may experience health effects from mould exposure, they are generally less vulnerable than young children. Older adults might have weakened immune systems or pre-existing health conditions that could make them susceptible, but the risks are significantly heightened in young children. The option considering height and weight is not a relevant criterion for assessing risk from mould exposure compared to the developmental and physiological factors affecting children.
