Abu Dhabi: All schoolgoing children aged four to 11 years who have returned to the UAE on or after January 3 must present a negative COVID-19 test prior to their physical return to school, the Abu Dhabi Department of Education and Knowledge (Adek) has said. To comply with the requirement, children must present a negative COVID-19 PCR test result with 96-hour validity, conducted via a nasal swab or saliva sample. The requirement was announced ahead of the resumption of face-to-face classes in Abu Dhabi schools after the three-week winter break. Although classes began on January 3, the Adek had announced a two-week distance learning period for all students in the emirate.
