Two more students at TDSB schools have been infected with the mumps.
The school board confirmed Tuesday that the students at Hodgson Senior Public School and King Edward Junior Public School had confirmed cases of the virus.
That brings the number of infected students to three. The first case was made public on Monday and involved a student at Forest Hill Collegiate.
Crews will spend Tuesday night into Wednesday morning cleaning and disinfecting the schools.
These cases are part of a larger outbreak of the mumps in Toronto.
The number of confirmed cases has doubled to 28, from 14 two weeks ago.
