Young people in their 20s are the most likely age group to contract any of four highly contagious mutations of COVID-19 circulating in Illinois, data showed Wednesday.

Individuals ages 20 to 29 constituted 21.7% of 1,603 total COVID-19 variant infections, and Illinoisans in their 30s followed at 15.4%, the Illinois Department of Public Health reported.

 

The 40-49 age group and 50-59 age group each represented about 14.3% of variant cases.

Children and teens ages 10 through 19 were 13.7% of those infected by variants, people in their 60s represented 9.4%, children up to age 9 were 6.3%, and seniors 70 and older were 4.9%.

"Current data suggests that COVID-19 vaccines authorized for use in the U.S. offer protection against the variants circulating," Centers for Disease Control Director Rochelle Walensky said at a briefing this week.

The most predominant COVID-19 variant in Illinois originated in the United Kingdom and has caused 72% of the variant cases, followed by a Brazilian strain linked to 21%.

New cases of COVID-19 totaled 2,765 Wednesday, marking a four-day streak of daily infections falling below 3,000, according to IDPH records.

Twenty-eight more people died of the respiratory disease, including one man in his 30s, one man in his 40s, and three women and one man in their 50s.
