The line graph illustrates the daily number of newly confirmed COVID-19 cases per one million residents, along with the test positivity rate in Cambodia over a period from May 2021 to March 2022.
Overall, the number of daily new confirmed COVID-19 cases saw a slight decline from May 9, 2021, to November 1, 2021, followed by a modest increase toward the end of the period. In contrast, the estimated test positivity rate rose sharply during the first half of this timeframe, followed by a significant drop in the subsequent months.
According to the graph, the number of new daily COVID-19 cases decreased slightly from May to November 2021, then increased modestly afterward. During the May to November period, which experienced a decrease, the number of new cases started at approximately 40 per one million people in Cambodia. This figure continued to fall sharply over the next few months, reaching a peak of around 60 cases in June. After fluctuating between 30 and 50 cases in September, the daily number of confirmed COVID-19 cases eventually dropped to nearly 6 cases by November 1, 2021. In contrast, the latter part of the period showed a growth trend. Specifically, on December 21, 2021, the count of infected cases in Cambodia hit the lowest point, with no cases recorded at that time. In the following months, the number rose dramatically to over 30 cases between January and February, before falling sharply again to around 6 cases by the end of the period.
However, the estimated test positivity rate increased markedly in the first half of the timeframe and then declined in the later months. During the May to September period that showed an increase, there was no testing data recorded for infected individuals on May 9, 2021. Two months later, the positivity rate surged significantly to around 20% in July, peaking at roughly 25% on September 12, 2021. In contrast, a downward trend was noted in the following months, with the estimated test positivity rate dropping to approximately 3%. This figure reached its lowest point of 0% on December 21, 2021, before skyrocketing to nearly 25% between January and February, ultimately standing at about 10% by the end of the period.
