People aged 70 years and over, people with compromised immune systems, and people with some chronic medical conditions are at greater risk of more serious illness from COVID-19.
The risk of serious illness from COVID-19 increases with age. The rate is higher for those with other serious health conditions or a weakened immune system.
People living with dementia or some form of cognitive impairment may find it difficult to follow instructions to reduce the risk of getting COVID-19, or alert others about potential symptoms.
