XBB.1.9.1 now the dominant Covid variant in Singapore
New Covid sequencing data shows that the XBB.1.9.1 variant now outcompetes XBB.1.5 in Singapore.
As you can see in the chart above, based on the most recent data from GISAID, XBB.1.9.1 is now found in 28% of sequences in Singapore, compared to just 12% for XBB.1.5. That is nearly three times the amount of XBB.1.9.1 sequences that we noted from Singapore, based on data from the 20th February 2023.
We posted the chart below on Twitter two days ago. It was based on GISAID date from the 20th February 2023. You can see, at that point, XBB.1.9.1 was found in just 10% of SARS-CoV-2 sequences.
