On September 28, 2020, this report was posted as an MMWR Early Release on the MMWR website (https://www.cdc.gov/mmwr). Approximately 56 million school-aged children (aged 5-17 years) resumed education in the United States in fall 2020.* Analysis of demographic characteristics, underlying conditions, clinical outcomes, and trends in weekly coronavirus disease 2019 (COVID-19) incidence during March 1-September 19, 2020 among 277,285 laboratory-confirmed cases in school-aged children in the United States might inform decisions about in-person learning and the timing and scaling of community mitigation measures. During May-September 2020, average weekly incidence (cases per 100,000 children) among adolescents aged 12-17 years (37.4) was approximately twice that of children aged 5-11 years (19.0). In addition, among school-aged children, COVID-19 indicators peaked during July 2020: weekly percentage of positive SARS-CoV-2 test results increased from 10% on May 31 to 14% on July 5; SARS-CoV-2 test volume increased from 100,081 tests on May 31 to 322,227 on July 12, and COVID-19 incidence increased from 13.8 per 100,000 on May 31 to 37.9 on July 19. During July and August, test volume and incidence decreased then plateaued; incidence decreased further during early September and might be increasing. Percentage of positive test results decreased during August and plateaued during September. Underlying conditions were more common among school-aged children with severe outcomes related to COVID-19: among school-aged children who were hospitalized, admitted to an intensive care unit (ICU), or who died, 16%, 27%, and 28%, respectively, had at least one underlying medical condition. Schools and communities can implement multiple, concurrent mitigation strategies and tailor communications to promote mitigation strategies to prevent COVID-19 spread. These results can provide a baseline for monitoring trends and evaluating mitigation strategies. School-aged children were stratified by age into two groups: children aged 5-11 years and adolescents aged 12-17 years. Confirmed COVID-19 cases were identified from individuallevel case reports submitted by state health departments for the weeks beginning March 1-September 13, 2020. † Confirmed cases had a positive real-time reverse transcription-polymerase chain reaction (RT-PCR) test result for SARS-CoV-2, the virus * https://nces.ed.gov/fastfacts/display.asp?id=372.
Preventing unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection, among adolescents is a public health priority. This report presents prevalence estimates for condom and contraceptive use among sexually active U.S. high school students from the 2019 Youth Risk Behavior Survey. Behaviors examined included any condom use, primary contraceptive method use, and condom use with a more effective contraceptive method, all reported at last sexual intercourse. Analyses were limited to sexually active students (i.e., those who had sexual intercourse with one or more persons during the 3 months before the survey). Except for any condom use, students reporting only same-sex sexual contact were excluded from analyses. Weighted prevalence estimates were calculated, and bivariate differences in prevalence were examined by demographic characteristics (sex, race/ethnicity, and grade) and other sexual risk behaviors (age of sexual initiation, previous 3-month and lifetime number of sex partners, and substance use before last sexual intercourse). Nationwide, 27.4% of high school students reported being sexually active (n = 3,226). Among sexually active students who reported having had sexual contact with someone of the opposite sex (n = 2,698), most students (89.7%) had used a condom or a primary contraceptive method at last sexual intercourse. Prevalence of any condom use at last sexual intercourse was 54.3%, and condoms were the most prevalent primary contraceptive method (43.9% versus 23.3% for birth control pills; 4.8% for intrauterine device [IUD] or implant; and 3.3% for shot, patch, or ring). Approximately 9% had used condoms with an IUD, implant, shot, patch, ring, or birth control pills. Using no pregnancy prevention method was more common among non-Hispanic black (23.2%) and Hispanic (12.8%) students compared with non-Hispanic white students (6.8%); compared with Hispanic students, using no pregnancy prevention method was more common among non-Hispanic black students. Prevalence of condom use was consistently lower among students with other sexual risk behaviors. Results underscore the need for public health professionals to provide quality sexual and reproductive health education and clinical services for preventing unintended pregnancy and STDs/HIV and decreasing disparities among sexually active youths.
Youths have experienced disruptions to school and home life since the COVID-19 pandemic began in March 2020. During January–June 2021, CDC conducted the Adolescent Behaviors and Experiences Survey (ABES), an online survey of a probability-based, nationally representative sample of U.S. public- and private-school students in grades 9–12 (N = 7,705). ABES data were used to estimate the prevalence of disruptions and adverse experiences during the pandemic, including parental and personal job loss, homelessness, hunger, emotional or physical abuse by a parent or other adult at home, receipt of telemedicine, and difficulty completing schoolwork. Prevalence estimates are presented for all students and by sex, race and ethnicity, grade, sexual identity, and difficulty completing schoolwork. Since the beginning of the pandemic, more than half of students found it more difficult to complete their schoolwork (66%) and experienced emotional abuse by a parent or other adult in their home (55%). Prevalence of emotional and physical abuse by a parent or other adult in the home was highest among students who identified as gay, lesbian, or bisexual (74% emotional abuse and 20% physical abuse) and those who identified as other or questioning (76% and 13%) compared with students who identified as heterosexual (50% and 10%). Overall, students experienced insecurity via parental job loss (29%), personal job loss (22%), and hunger (24%). Disparities by sex and by race and ethnicity also were noted. Understanding health disparities and student disruptions and adverse experiences as interconnected problems can inform school and community initiatives that promote adolescent health and well-being. With community support to provide coordinated, cross-sector programming, schools can facilitate linkages to services that help students address the adverse experiences that they faced during the ongoing COVID-19 pandemic. Public health and health care professionals, communities, schools, families, and adolescents can use these findings to better understand how students’ lives have been affected during the pandemic and what challenges need to be addressed to promote adolescent health and well-being during and after the pandemic.
