THE Influenza A (H1N1) viral strain is no longer the dominant flu virus here, Singapore's Ministry of Health said yesterday.
And, since the strain has been found to be in the process of becoming seasonal in nature, Singapore and other Asean countries have stepped down, or are stepping down, their pandemic alert levels, said Health Minister Khaw Boon Wan.
The Health Ministry said that, as of last week, Influenza A (H1N1) comprised 31 per cent of all flu cases in the community here. But it is no longer the main circulating flu strain in Singapore, as it was as late as in May.
The seasonal strains, Influenza A (H3N2) and Influenza B, now constitute 45 per cent and 24 per cent of flu cases here, respectively.
In the last week of May, H1N1 accounted for 50 per cent of circulating strains, with the rest made up of H3N2 and Influenza B.
