July 27, 2021
CDC officials are investigating a COVID-19 delta variant epidemic linked to an Oklahoma gymnastics facility. As reported by KOCO News in the article CDC Reports COVID-19 Delta Variant Outbreak Associated With Oklahoma Gymnastics Facility
, the Oklahoma State Department of Health was notified by its public health laboratory of Delta Variant specimens clustered in central Oklahoma between May 12 and 18, according to the CDC news release. Public health surveillance data indicated that these cases were associated with a local gymnastics facility, officials didn't specify which one.
Staff from the OSDH local health department spoke with those who tested positive for the variant and traced their contacts. This outbreak was linked to 47 COVID-19 cases (ages 5 to 58), including 21 laboratory-confirmed delta variant cases and 26 epidemiologically linked cases, according to the CDC. Two adult patients were hospitalized (both unvaccinated and epidemiologically linked) and one required intensive care among the 47 cases.
CDC officials reported 10 of 16 gymnast cohorts and three staff members were affected. In seven (27%) of the 26 houses with outbreak-related cases, secondary cases occurred. Forty (85%) of people with outbreak-related COVID-19 hadn't been vaccinated at all. 3% of those who had received one dosage of Moderna or Pfizer-BioNTech more than 14 days before a positive test result were considered partially vaccinated since they hadn't received the second dose. Four people (9%) were fully vaccinated after receiving two doses of Moderna, Pfizer or a single dose of Janssen (Johnson & Johnson) vaccine more than 14 days before a positive test result. These findings suggest that the delta variant is highly transmissible in indoor sports settings and within households.
