Coronavirus Disease 2019 (COVID-19) WHO Thailand Situation Report 232 – April 20, 2022 – Thailand

Situation analysis

The average number of new laboratory-confirmed (PCR-positive) COVID-19 cases reported per day decreased by 19% in the last 7 days compared to the previous week, when a total of 4 million reported cases of COVID-19 passed in Thailand. This is the second week of fall; however, we will have to wait a few more weeks to know if there has been any increased infection as a result of Songkran family reunions. The average number of probable (ATK-positive) cases reported per day over the last 7 days (13,630) decreased significantly by 29% compared to the week before (19,333). This may also be a result of reduced reporting during Songkran. Since not all probable (ATK-positive) cases are subsequently confirmed by PCR testing, the probable “total” daily case remains high. While new cases may have fallen or have not been reported, severe and ventilated cases and deaths continue to rise as they have been since the beginning of the year.

Bangkok continues to report the highest daily number of COVID cases and has reversed the average fall of the last few weeks, with the average number of new COVID-19 cases reported on the day of Bangkok in the last week (3,195) 1.9% higher than the week before (3,136).

The average daily number of all currently ‘active’ COVID-19 cases (212,174) over the last seven days decreased by 13% compared to the previous week. Most cases continue to be monitored in hospitals, community isolation, and home isolation. The average number of COVID cases occupying hospital beds per day during the past week (56,216) decreased by 11% compared to the week before (63,425). The average bed occupancy for the first time has been below 60,000 since mid-February.
In the opposite direction, deaths increased by 24% with an average of 124 daily deaths reported in the past week compared to 100 for the previous week. This continues the steadily rising death toll that has occurred since January.

The average daily number of severe COVID-19 cases over the last seven days has passed two thousand (2,062) for the first time since the beginning of November 2021, representing a 5% increase over the average number reported for the previous week (1,967). The average daily number of ventilated COVID-19 cases over the last seven days (897) represents an increase of 8% compared to the average number reported for the previous week (633).

Although the number of seriously ill COVID-19 cases remains lower than the peak in August 2021, both serious and ventilated cases have been steadily increasing, with ventilated cases increasing faster and only 23% below their highest ever reported levels in August 2021. At despite these increases, there is still capacity in healthcare to hospitalize patients.

The policy of not confirming by PCR testing for all probable cases, as well as the widespread use of rapid antigen testing (including the available ‘over-the-counter’ purchases that may not be reported), continue to make it difficult to monitor the situation accurately. However, based on the reported data, the increasing transmissibility of the Omicron variant is evident, with almost half (49%, 1.8 million) of all COVID cases (4 million) in Thailand reported in the last 4 months from 1 January 2022 , which was the time when the Omicron variant began to dominate the circulation.

Even with the current high caseload of COVID-19, vaccination rates in Thailand continue to significantly reduce the level of serious illness and death caused by circulating COVID-19 strains.
High vaccination rates also help reduce COVID-19 transmission. However, vaccination rates are still low in some provinces and in some important risk groups. The CCSA reported that of the 124 deaths reported on April 18, 99% were in vulnerable groups, with 94% not receiving a booster vaccination that has been shown to be extremely effective in preventing serious illness against the worrying Omicron variant.
