    • Description:
      According to sequencing data reported by CDC, the highly transmissible B.1.617.2 (Delta) Variants of SARS-CoV-2, the Virus that causes COVID-19, has been the predominant lineage circulating in Louisiana since the week of June 20, 2021 (1). In Louisiana, the increased spread of the Delta Variants corresponded with the start of the state’s fourth and largest increase in average daily COVID-19 incidence to date (1,2). This report describes COVID-19 outbreaks in Louisiana youth summer camps as the Delta Variants became the predominant lineage during June–July 2021. This activity was reviewed by the Louisiana Department of Health (LDH) and was conducted consistent with applicable state law and LDH policy.*

      During June–July 2021, LDH used camp reports and contact tracing data† to identify 28 camp outbreaks§ statewide, which included a total of 321 COVID-19 cases¶ among an estimated 2,988 campers and staff members. Fourteen (50.0%) of the camps were day camps, and 14 (50.0%) were overnight camps. The mean outbreak size was 11.5 cases (range = 2–59 cases); the mean outbreak size of day camps was 9.3 cases (range = 2–21 cases) and overnight camps was 13.6 cases (range = 2–59 cases). Compared with June–July 2020, when two outbreaks (each with five confirmed camp-associated cases) were identified statewide, this represented a thirty-one-fold increase in confirmed camp-associated cases.

      Among the 321 camp-associated cases identified during the June–July 2021 outbreaks, the median age was 12 years (range = 5–54 years), 274 (85.4%) cases occurred among campers (range = 5–18 years), and 47 (14.6%) among staff members (range = 16–54 years). Among all campers with COVID-19, two (0.7%) were fully vaccinated against COVID-19; 133 (48.5%) were age-eligible but not vaccinated (representing 98.5% of the 135 vaccine-eligible campers with COVID-19), and 139 (50.7%) were not age-eligible for vaccination. All cases among staff members occurred in persons who had not received COVID-19 vaccine.
