COVID cases increase 75% in DuPage County, hospitalizations also on the rise

The DuPage County Health Department (DCHD) is reporting a 75% increase in COVID-19 cases and a 44% increase in COVID-19 hospitalizations over the past week among DuPage County residents.

Currently, the Centers for Disease Control and Prevention (CDC) is projecting that the Delta variant comprises more than 83% of new COVID-19 cases across the country and creates a higher level of risk for unvaccinated people. In DuPage County, a notable increase in Delta variant cases has also been identified. Thus, DCHD urges unvaccinated residents 12 years and older to get vaccinated against COVID-19 as soon as possible, according to a DCHD news release.

COVID-19 vaccinations are safe and highly effective at preventing severe illness, hospitalization and death in those who are fully vaccinated. In DuPage County, more than 99% of COVID-19 cases and more than 99.9% of hospitalizations and deaths related to COVID-19 since mid-December have been identified in persons not fully vaccinated. Additionally, Delta variant cases have nearly doubled in the past week—up from 11 cumulative cases on July 14 to 21 cases as of July 21, based on limited genomic sequencing efforts, the release stated.

According to the latest CDC COVID-19 vaccination data, more than 81% of eligible residents 12 years and older in DuPage County have received at least one COVID-19 vaccine dose, and 65% are fully vaccinated. Additionally, 98% of DuPage County residents ages 65 years and older have received at least one COVID-19 vaccine dose, and 82% are fully vaccinated.

Notably, among 12- to 17-year-olds in DuPage County, 57% have received at least one COVID-19 vaccine dose, and only 49% are fully vaccinated. Students who are fully vaccinated by the beginning of the school year will not be required to quarantine if exposed to someone with COVID-19, leading to fewer disruptions in their ability to attend school, participate in sports, or spend time with their friends.

“We’re increasingly learning that children and adolescents, even if without symptoms and with lower risk for severe illness, are still able to transmit COVID-19 infection to others, within and outside their household,” said Karen Ayala, executive director of DuPage County Health Department.

“Illinois Department of Public Health has reported several camp outbreaks this summer, especially where masking is not implemented, screening testing is not conducted and the Delta variant is spreading. This results in preventable illness as well as disrupted lives in work, school and time spent away from family and friends.

“We need our children to return to school with low to zero COVID-19 activity, not rising activity—we need to turn things around in the coming weeks for a safer, more enjoyable, and productive school environment for students, staff, and our community,”

The DCHD recently released a statement on COVID-19 prevention strategies in schools. DCHD strongly recommends school districts begin the 2021-22 school year with layered COVID-19 prevention strategies in place that are outlined in the updated CDC guidance for K-12 schools, which were fully adopted by the Illinois Department of Public Health.

However, health departments do not have the authority to require or enforce these strategies as school leaders and local school districts hold the ultimate authority to develop plans to return to school and ensure a safe school environment. To view the complete statement, visit

COVID-19 community transmission in DuPage County remains at a moderate level. As the county experiences a rise in case activity associated with the more dangerous Delta variant, individuals who are not fully vaccinated or are immunocompromised should continue practicing preventive measures as they are at greater risk of contracting the more transmissible variants, some of which are more likely to lead to severe outcomes.

In addition, to help interrupt and prevent community spread, persons with COVID-19 infection need to self-isolate and their close contacts need to self-quarantine and get tested unless they have been fully vaccinated against COVID-19 or have had COVID-19 infection within three months of exposure.
