Description:
What is already known about this topic? The SARS-CoV-2 B.1.617.2 (Delta) Variants emerged in India and is currently widespread. Evidence suggests that it is potentially more transmissible than other Variantss.

What is added by this report? During April 15–May 3, 2021, 47 COVID-19 cases were linked to a gymnastics facility, including 21 laboratory-confirmed B.1.617.2 cases and 26 epidemiologically linked cases. The overall facility and household attack rates were 20% and 53%, respectively.

What are the implications for public health practice? The B.1.617.2 Variants is highly transmissible in indoor sports settings and households, which might lead to increased attack rates. Multicomponent Prevention strategies including vaccination remain important to reduce the spread of SARS-CoV-2 among persons participating in indoor sports and their contacts.

The B.1.617.2 (Delta) Variants of SARS-CoV-2, the Virus that causes COVID-19, was identified in India in late 2020 and has subsequently been detected in approximately 60 countries (1). The B.1.617.2 Variants has a potentially higher rate of Transmission than other Variantss (2). During May 12–18, 2021, the Oklahoma State Department of Health (OSDH) Acute Disease Service (ADS) was notified by the OSDH Public Health Laboratory (PHL) of 21 SARS-CoV-2 B.1.617.2 specimens temporally and geographically clustered in central Oklahoma. Public health Surveillance data indicated that these cases were associated with a local gymnastics facility (facility A). OSDH ADS and local health department staff members reinterviewed persons with B.1.617.2 Variants–positive laboratory results and conducted contact tracing. Forty-seven COVID-19 cases (age range = 5–58 years), including 21 laboratory-confirmed B.1.617.2 Variants and 26 epidemiologically linked cases, were associated with this outbreak during April 15–May 3, 2021. Cases occurred among 10 of 16 gymnast cohorts* and three staff members; secondary cases occurred in seven (27%) of 26 households with outbreak-associated cases. The overall facility and household attack rates were 20% and 53%, respectively. Forty (85%) persons with outbreak-associated COVID-19 had never received any COVID-19 vaccine doses (unvaccinated); three (6%) had received 1 dose of Moderna or Pfizer-BioNTech ≥14 days before a positive test result but had not received the second dose (partially vaccinated); four persons (9%) had received 2 doses of Moderna or Pfizer-BioNTech or a single dose of Janssen (Johnson & Johnson) vaccine ≥14 days before a positive test result (fully vaccinated). These findings suggest that the B.1.617.2 Variants is highly transmissible in indoor sports settings and within households. Multicomponent Prevention strategies including vaccination remain important to reduce the spread of SARS-CoV-2, including among persons participating in indoor sports† and their contacts.
