KFL&A Public Health declares COVID-19 outbreak at LaSalle Secondary School

Kingston, Frontenac, Lennox and Addington (KFL&A) Public Health have declared an outbreak of COVID-19 at LaSalle Intermediate and Secondary School.
The outbreak was officially declared on Friday, Dec. 17, 2021, however, according to the active COVID-19 case listing provided by the Limestone District School Board (LDSB), the first case was detected at the school on Sunday, Dec. 12, 2021, and included one student case. Two further cases were detected on Thursday, Dec. 16, and Friday, Dec. 17, 2021 (two cases each day) and the outbreak was declared. One more case of the virus was detected on Saturday, Dec. 18, 2021.
According to KFL&A Public Health, there are six cases involved in the outbreak, with one of those cases resolved (and five active). The LDSB only what appears to be two outbreaks at the school, consisting of five total cases in one outbreak (one resolved), and one active case in the other. It is unclear what the reason is for this discrepancy.
Currently, the LDSB is listing 118 active cases of COVID-19 within the board, and 11 LDSB schools are currently dealing with declared outbreaks. According to KFL&A Public Health, there are 19 active outbreaks in schools from education boards within the region, consisting of a total 97 active cases in local schools.
The LDSB has not listed whether LaSalle Secondary remains open with visitor restrictions, or if the school/some cohorts have pivoted to online class delivery.
