Hong Kong has recorded no new locally transmitted Covid-19 cases for a fourth consecutive day.
The Centre for Health Protection reported just one imported coronavirus case on Tuesday, involving a woman who recently flew in from Indonesia.
As infection figures remain at a low level, the Education Bureau announced that schools can resume half-day in-person classes for all pupils from May 24.
Currently, schools can have two-thirds of their children on campus at any one time, unless the teachers are getting tested regularly for Covid.
The bureau said classes should continue to open only on a half-day basis, to avoid pupils having to eat lunch there.
