Philippines detects first BA.4 case
The Philippines has detected its first case of the Omicron BA.4 subvariant in a Filipino who flew in from the Middle East on May 4.
The Department of Health (DOH) confirmed the positive test result on May 8, and noted that the patient was asymptomatic.
While the European Centre for Disease Prevention and Control (ECDC) has not observed any change in severity compared to other Omicron subvariants, faster transmission could lead to a spike in cases overwhelming hospitals and clinics.
The DOH is coordinating with local government units to implement detection and isolation activities.
