The agency cited an assessment by the World Health Organization regarding the BA3.2 variant, noting that currently approved COVID-19 vaccines are “expected to continue providing protection against severe disease,” and adding that there is “no data indicating increased severity” associated with the variant.
According to the KDCA, BA3 — a sublineage of the Omicron variant — briefly appeared in early 2022 before disappearing. Its subvariant, BA3.2, was first identified in South Africa in November 2024.
The agency said that although the BA3.2 variant could contribute to a rise in cases domestically, it is continuing to closely monitor the situation.
The COVID-19 positivity rate at local clinics rose to 6.3 percent in the 15th week (April 5–11), up from 4.7 percent a week earlier.
During the same period, the BA3.2 variant accounted for 23.1 percent of cases, making it the third most prevalent strain. As of last month, PQ2 and NB1.8.1 led with 34.6 percent each, followed by BA3.2 at 23.1 percent and XFG at 3.8 percent.
A KDCA official said, “The WHO has assessed that the BA3.2 variant does not significantly change disease severity, and current vaccines remain effective. Excessive concern is unnecessary at this stage.”
The official, however, urged high-risk groups, including those aged 65 and older and immunocompromised individuals, to get vaccinated, with vaccinations available through June 30.
