The Delta Covid-19 variant has overtaken the Alpha mutation as the dominant strain in Thailand with the highly contagious virus responsible for adding more than 13,000 new cases on Wednesday alone.
A total 13,002 new coronavirus cases were reported today along with 100 additional deaths.
Department of Medical Sciences Director-General Dr. Supakit Sirilak said Tuesday that 63 percent of more than 3,000 cases analyzed were found to be the Delta strain first found in India, while 34 percent are the Alpha variant first found in Great Britain. The rest are the Beta strain from South Africa, which is dominant in the Deep South.
Mae Hong Son, Kanchanaburi, Samut Songkhram, Chachoengsao, Trat, Surin, Chumphon, Nakhon Si Thammarat, Krabi, Phang Nga and Pattani reported their first Delta cases recently, raising the number of provinces where the variant has been found to 72.
Supakit added that there were no new cases of co-infections, after the department reported early last week that seven construction workers in Bangkok were suspected to have been infected by both the Alpha and Delta variants simultaneously.
