The Department of Health (DOH) has detected a total of 54 cases of Omicron subvariant XBB.1.9.1 in the Philippines.
According to the department's latest Covid-19 biosurveillance <a href="https://doh.gov.ph/covid19-variants" target="_blank" rel="noopener">report</a>, 39 XBB.1.9.1 cases were found among the 199 samples sequenced by the University of the Philippines-Philippine Genome Center from April 3 to 11.
"The XBB.1.9.1 is an XBB sublineage that was recently added to the list of variants under monitoring by the WHO last March 30," the DOH said.
