Previous Close Contact with Confirmed Cases

Definition of “Close Contact”

What is the definition of “close contact”? What should I do if I come into “close contact” with someone who has been diagnosed to have COVID-19?

“Close contacts” are individuals who, from 2 days before the first symptoms of the infected case became apparent or, in an asymptomatic case, from 2 days before the case’s first positive test, engaged with an infected person in mask-off activities (e.g. eating or drinking together) or mask-on activities within a poorly ventilated area for 30 minutes or longer.

However, those individuals who came into contact with an infected person are not considered as “close contacts” if the potential contact was wearing (1) a surgical mask plus a reusable mask (worn over the surgical mask) OR (2) a single KF94, KN95 or N95 mask, AND the test positive case was wearing at least a surgical mask.

If you have “close contact” with an infected person, please return to the campus no earlier than 7 days from the last date of contact with the infected person. Please undergo a Rapid Antigen Test (RAT) or a Polymerase Chain Reaction (PCR) test on a daily basis during the 7-day period.

If you feel unwell, please seek medical attention at designated clinics or call the hotline 1 836 115 for advice.
