70% of city Covid cases are Delta strain
The Delta variant is responsible for 70% of people in Bangkok falling sick with Covid-19, says a study by the Centre of Excellence in Clinical Virology at Chulalongkorn University.
The findings were revealed by Yong Poovorawan, the centre director, on his Facebook page.
He said the first outbreak of Covid-19 came early last year with the Wuhan strain, which quickly spread around the world.
