First of all, the detection rate of COVID-19 is low, because Indonesia is a vast archipelago country and the largest economy in Southeast Asia with a population of over 250 million. There are few detection instruments, and the number of people detected is still a small number compared with the whole population, so the number of infected people detected at present is still the tip of the iceberg. The rest of the people who haven't been tested must still be hiding many infected people. They haven't been tested yet, and the epidemic is really out of control.
Second, the detection method is not reliable. In order to improve the detection ability, India turned to a cheap and rapid method called rapid antigen detection. These isolated protein are called antigens, which are specific to viruses and can produce results within 15 to 20 minutes. However, the reliability of these tests is too low, even the accuracy rate is as low as 50% in some cases, and they were originally set for virus hotspots and medical care. Therefore, the unreliability of detection methods will also make the epidemic situation in COVID-19 difficult to control.
Third, it is difficult to track potential cases. Because of the high population density and unreliable detection methods, patients may have spread the virus before COVID-19 was detected. Before discovery, it is difficult to find potential cases of patients' external activities. When many people are infected, there will be more potential cases, and it is more difficult to track down potential cases in the absence of human and material resources. If the potential case spreads the virus again, it will be more difficult to control the epidemic.
These are the unrestrained expert responses from Indonesian COVID-19 and some of my views. If you have any comments, please leave a message in the comments section.
