BA.2 is spreading rapidly in around 40 countries, including Singapore, India, Denmark, Sweden and the UK.
"About three weeks after it was first discovered among foreign travellers, the BA.1 variant has spread quickly throughout a number of countries with several clusters reported in populated and tourism areas," he said. Supphakit said that so far there was no evidence BA.2 was different from BA.1 in terms of transmissibility, the potential for a patient to develop severe symptoms, or the ability to evade immunity created after recovering from Covid-19 or by receiving a vaccine.
