According to the ministry, the COVID-19 pandemic has been still under control when the daily number of new cases stands at double digits.

Regarding the recently discovered XBB.1.5 sub-variant of Omicron, the ministry cited the World Health Organisation saying that the sub-variant is the cause behind the increase of COVID-19 infections in the US and has been detected in Europe, Australia and parts of Southeast Asia.

Angela Pratt, Chief Representative of WHO in Vietnam, said current diagnostic and protective measures remain in place, including WHO-approved COVID-19 vaccines.

The Ministry requested localities to enhance surveillance at border gates, public areas and medical establishments to swiftly detect and handle suspected cases, especially those entering from areas which record COVID-19 outbreaks and appearance of new variants.
