The Department of Transportation (DOTr) said the MRT-3 conducted contact tracing and mass swab testing among its employees following its first reported case of COVID-19 among the depot office personnel, which later yielded 33 positive cases on January 20. The additional three positive cases have been confirmed Monday, January 27. All personnel who have tested positive are already in quarantine. “It is also with great sadness that we confirm that one of our fellow public servants in the MRT-3 Depot who got infected by COVID-19 passed away earlier this week,” the DOTr said in a statement released late Wednesday evening.
