There were 397 deaths from diseases of the heart reported in Illinois in the week ending Jan. 15, making up 16 percent of total deaths by all causes in Illinois, according to The Centers for Disease Control and Prevention.

In the week ending Jan. 15, there were 2,482 deaths in the state. 16 percent of deaths were caused by heart disease, 13.6 percent were from cancer and 52.9 percent were from COVID-19.

Studies show doctors and medical examiners may underreport Alzheimer's disease and dementia-related conditions as the underlying cause of death on death certificates, according to the National Institute on Aging.

Once infected, older adults with dementia are likely to develop a more severe and dangerous illness. The diseases which make an older adult more vulnerable to COVID-19 are age-associated chronic conditions, according to the Bright Focus Foundation.
