The cluster in Pathumthani has been contained and the testing programme there is returning low levels of infection rates, an official said Monday, while no new coronavirus case was found in Bangkok in the past 24 hours.
A total of 13,293 proactive tests have been conducted at high-risk communities within the Pornpat Market cluster in Pathumthani since February 9, resulting in 430 confirmed cases, said Apisamai Srirangsan, the spokeswoman of the Center for Covid-19 Situation Administration (CCSA).
“The results show that out of 100 tests in the cluster, we will find three cases and health officials are confident that this is a safe level,” she said.
“This means that the area of infection is contained and measures to prevent any further spread were effective,” Apisamai said.
An infection rate of 5 percent or lower for two straight weeks is a criterion for authorities to consider lifting restrictions, the World Health Organization has said in reports on the pandemic.
The Pornpat Market cluster, which started when a vendor tested positive on February 6, has produced 430 identified cases. Of those, 401 were found in Pathumthani and of that, 385 were found at the market alone. The remaining 29 were found across a total of nine provinces.
The CCSA said they have found 89 new coronavirus cases in the past 24 hours.
Of those, 73 were local infections and 16 were found in quarantine facilities.
Of the 73 local infections, 59 were found via tests at medical facilities and 14 via proactive tests in high-risk communities, mostly in Samut Sakhon and Pathumthani.
This brings the total number of infections since the pandemic began last year to 25,504 cases. While 24,361 people have recovered from the disease, 1,060 patients are still being treated.
There was one new fatality, bringing the death toll to 83 people.
The second wave of the outbreak has led to 21,267 confirmed cases and 23 deaths since December 15. Of the total confirmed cases during the second wave, 78 per cent were found in Samut Sakhon alone.
Clusters and provinces
The second wave of the outbreak has reached 63 out of the 77 provinces in Thailand so far. Of the 63, there are now 50 provinces that have not reported any new case in the past week.
The hardest-hit province continues to be Samut Sakhon, where the second wave began, which reported 15,953 confirmed cases since 15 December.
This was followed by Bangkok (950), Chonburi (653), Rayong (584), Pathumthani (519), Samut Prakan (365), Chanthaburi (221), Nonthaburi (174), Tak (151), Ang Thong (121) and Nakhon Pathom (109), respectively.
