Amid doubts caused by the relatively low number of COVID-19 tests conducted in Taiwan, Vice President Chen Chien-jen (陳建仁) has defended the nation’s practices, saying that large volumes of tests are only needed when sources of infection cannot be traced.
As of Wednesday last week, Taiwan had conducted 20,014 tests for the novel coronavirus, compared with 307,024 by South Korea, raising questions over whether Taiwan’s testing has been aggressive enough.

He said that such a practice could increase the number of false negative results.
More testing “might not only not help efforts to stem the outbreak, it could even create a quarantine loophole,” Chen Shih-chung said, adding that those with false negative results could move about without taking precautions, thinking that they are free of the virus, while infecting others.
Chen Chien-jen, an epidemiologist by training, on Monday said on Facebook that the prevalence of the novel coronavirus in Taiwan is less than one per 100,000 people, and that “only a few cases have unknown sources.”
As such, the government has concentrated its testing on those who have come in contact with infected patients and those categorized as highly vulnerable to COVID-19, he said.
“Such a practice guarantees that the tests are proper and efficient, and in line with cost-benefit principles,” the vice president said.
In addition, he provided data from 13 nations that have conducted at least 15,000 tests on their volume of testing, the number of positive cases found and the prevalence of the disease in their populations.
The figures generally showed that “the lower the rate of positive tests, the broader the coverage of tests of potentially infected people,” Chen Chien-jen.
Of the 13 nations, Taiwan had five positive results for every 1,000 tests conducted, trailing only the United Arab Emirates at 0.8 positive results per 1,000 tests and Russia with 1.2 positive results per 1,000 tests, he said.
Taiwan had 0.45 infections per 100,000 people, the second-lowest ratio after Russia’s 0.14 infections per 100,000, he added.
However, Chen Chien-jen acknowledged that the correlation between positive test rates and infection rates per 100,000 people was not absolute, citing statistics from France, Belgium and South Korea, where there were about 16 infections per 100,000 people, but their positive test rates varied greatly.
While South Korea saw 27.9 positive results per 1,000 tests, Belgium reported 80.9 positive results per 1,000 tests and France 167.4 positives per 1,000 tests.
The figures suggest that South Korea and Belgium conducted more tests on people who were not infected, while France tested more people who were infected, Chen Chien-jen said.
The center said that COVID-19 tests are being conducted on “high-risk” subjects, divided into two groups: those who have come in contact with foreigners who had respiratory symptoms and a fever; and people with pneumonia or who have a fever and respiratory symptoms after returning from countries for which the highest level of travel advisory has been issued.
