The second- and third-generation gene sequencing analysis conducted by Guangdong provincial CDC has found that the virus in the two previously-reported cases is the Delta variant.

The epidemiological investigation shows that the two newly confirmed cases have clear epidemiological links with previously reported confirmed cases, which means they are all in the same transmission chain. People who visited the same places as the above-mentioned confirmed cases simultaneously should report to the community in time and take the initiative to receive a nucleic acid test.As of 2pm today, a total of 535 close contacts have been identified, all of whom have been quarantined and sampled for nucleic acid testing.In a bid to effectively control the epidemic, mass nucleic acid testing was carried out in Dalang Town and its six neighbouring towns of Changping, Liaobu, Dongkeng, Songshan Lake, Huangjiang and Dalingshan yesterday. 837,400 samples were collected in Dalang Town, which were all negative except for one abnormality. A total of 2,660,936 samples were collected in six neighbouring towns, and the results were all negative.

Dalang has also started its second round of nucleic acid testing for all residents.In this round of citywide mass nucleic acid testing, Dongguan has arranged nearly 20,000 medical staff to collect the samples and prepare materials that can meet the testing needs of more than 12.2 million people. As of 4pm today, 8.229 million samples have been collected in this round of testing, which may last until 10pm today.
