What type of individuals are more susceptible to infections from environmental pathogens?

Immunocompromised individuals are more susceptible to infections from environmental pathogens due to their weakened immune systems. This group includes people who have conditions such as HIV/AIDS, those undergoing chemotherapy, organ transplant recipients, and individuals taking immunosuppressive medications. Their reduced ability to fight off infections makes them particularly vulnerable to pathogens that might not significantly affect healthy individuals.

Young adults generally have stronger immune systems and are less likely to suffer severe consequences from environmental pathogens. Healthcare workers, while often exposed to a variety of potential infections, typically have protective measures in place such as vaccinations and training that mitigate their risk. Senior citizens, though at increased risk relative to younger populations due to the natural decline in immune function with age, generally do not possess the same heightened vulnerability as those who are immunocompromised, especially if they are otherwise healthy.
