There were 87 deaths with chronic lower respiratory disease listed as the underlying cause reported in Illinois during the week ending June 17, a 3.3% decrease from the previous week, according to The Centers for Disease Control and Prevention.

In the week ending June 17, there were 2,012 deaths in the state. 23.1% of deaths were caused by heart disease, 23% were from cancer and less than 0.5% were from COVID-19. Additionally, 9.3% of deaths were from Alzheimer's disease and dementia.

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.
