The Omicron BA.4 and BA.5 subvariants have been detected in several countries, including Singapore, as more transmissible leads to a surge of infection cases driven by the two subvariants.
The Minister of Health Dato Seri Setia Dr Haji Mohd Isham bin Haji Jaafar in a press conference on Wednesday, explained that the subvariants have not much different from the BA.1 and BA.2.
“The subvariants have been spread in Western countries, which is more transmissible than the current BA.1 and BA.2 subvariants,” he said.
He further explained that no indication was found on BA.4 and BA.5 associated with more severe symptoms.
The government is still monitoring the situation by performing genomic sequencing with an average of 800 to 1000 positive cases since early this year.
The BA.4 and BA.5 subvariants were first identified in South Africa in January and February this year respectively, and currently seeing a surge of new Covid-19 cases and higher hospitalisation.
According to a report, the country’s new cases have jumped from an average of 300 per day in early April to 8,000 cases per day in May. Meanwhile, Singapore has recently reported three local cases of which two cases were infected with the BA.4 and one local case was identified with the BA.5 variants.
