Who is identified as being at higher risk for severe illness from COVID-19?

The identification of older adults and individuals with underlying health conditions as being at higher risk for severe illness from COVID-19 is based on extensive research and data collected throughout the pandemic. Older adults, particularly those aged 65 and over, have been shown to experience more severe outcomes from COVID-19, such as hospitalization and death, compared to younger age groups.

Additionally, individuals with underlying health conditions—such as heart disease, diabetes, obesity, chronic respiratory diseases, and compromised immune systems—have also been identified as particularly vulnerable. These pre-existing health conditions can complicate the body’s response to viral infections and increase the likelihood of severe complications.

Public health guidance has consistently emphasized monitoring and protecting these higher-risk groups, recognizing the importance of targeted interventions, such as vaccination and tailored health care resources, to help mitigate their risk of severe illness. Understanding this demographic helps inform public health policies and practices to safeguard those most at risk during health crises like the COVID-19 pandemic.
