A confirmed case is defined as the isolation of Streptococcus pneumoniae from a normally sterile body site (e.g., blood or cerebrospinal fluid) in a resident of LA County. All reported cases are investigated by DPH to determine if they meet the case definition. A probable case lacked sufficient information to establish if the confirmed case definition was met. There were 11 probable cases in the 2019–2020 season and 10 probable cases in the 2020–2021 respiratory season.
