FRIDAY, Sept. 25, 2020 (HealthDay News) — From May to August 2020, there was a decrease in the median age of COVID-19 cases in the United States, according to research published in the Sept. 23 early-release issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report<\/i>.<\/p>\n
Tegan K. Boehmer, Ph.D., from the CDC COVID-19 Response Team, and colleagues examined the changing age distribution of the COVID-19 pandemic during May to August by assessing COVID-19-like illness-related emergency department visits, positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcription-polymerase chain reaction (RT-PCR) test results, and confirmed COVID-19 cases.<\/p>\n
The researchers found that from May to July and August, the median age of COVID-19 cases declined from 46 to 37 and 38 years, respectively, nationwide. In all U.S. Census regions, similar patterns were seen for COVID-19-like illness-related emergency department visits and positive RT-PCR test results. During June to August, COVID-19 incidence was highest among adults aged 20 to 29 years, who accounted for >20 percent of all confirmed cases. In regional outbreaks of COVID-19 in the Southern United States in June, increases in the percentage of positive SARS-CoV-2 test results among adults aged 20 to 39 years preceded increases among adults aged \u226560 years by an average of 8.7 days.<\/p>\n
“Strict adherence to community mitigation strategies and personal preventive behaviors by younger adults is needed to help reduce their risk for infection and minimize subsequent transmission of SARS-CoV-2 to persons at higher risk for severe COVID-19,” the authors write.<\/p>\n
