MANILA: Health authorities have detected 618 Omicron variant cases in the latest whole-genome sequencing run, mainly composed of the BA.2 sub-lineage or the “stealth Omicron.” According to the Department of Health (DOH), the additional Omicron variant cases composed 91.29 percent of all 677 samples sequenced.

“Both the original Omicron lineage, B.1.1.529, and its sub-lineages, BA.1 and BA.2, have been detected in the country. The earliest detection of the BA.2 sub-lineage was on December 31, 2021, and was found to be the majority of Omicron cases in the latest batch,” the DOH said in a statement. According to DOH, data gathered by the health department and the University of the Philippines – Philippine Genome Center and National Institutes of Health showed that “there is no significant difference in BA.1 and BA.2 characteristics in terms of transmissibility or severity of the disease.”

The DOH said it would continue to investigate why BA.2 has become more prevalent than BA.1 but noted that so far, the detection of BA.2 does not require a significant change in the COVID-19 response.
