So far, two methods of COVID-19 prevention and control, namely vaccines and specific drugs, have not been available, so the measures that have been implemented in most countries are testing and isolating patients.

According to recent studies, over 75% of people carrying the new coronavirus virus have no symptoms. This is the main source of infection in the community. Preventing the disease is nothing more than isolating the entire sick person. But to do that, large-scale testing is needed.

The US sets a goal of 1 million tests per day

Extensive testing is more beneficial than identifying infected and isolated people. Firstly, it allows local authorities and epidemiologists to map out disease outbreaks and isolate the community.

Second, the test allows sketching of the scale of the epidemic as well as tracking its spread.

Third, it allows hospitals to plan beds, human resources and medical equipment as well as help protect health workers.

Finally, the virus information allows virologists to study the nature and mutations from which to trace the origin of the virus.

According to the New York Times, recent studies by Mount Sinai Hospital (New York, USA) show that cases of coronary infections in New York mainly come from Europe rather than from China.

South Korea is a pioneer in wide area testing. As one of the countries with the largest number of people infected with COVID-19 in the early stages, Korea has succeeded in limiting community spread.

Compared to Italy, on March 1, Italy had only 1,700 cases and 41 deaths, while in Korea, there were 3,736 cases and 21 deaths. After exactly three weeks, the numbers in Italy were 59,138 people infected and 5,476 deaths, while in South Korea were 8,897 and 104.

A Bloomberg article wrote: “With all cafes and shops open, large-scale testing in South Korea was successful.”

The United States with more than 1.2 million people infected is the most infected country in the world, but the United States is also the country that has tested more than any other country, with more than 6 million times.

In the early days of the epidemic, all tests in the US had to go through the CDC (US Centers for Disease Control and Prevention), now testing scores are available in all states and the number of tests a day has increased. from 100,000 at the end of March to 300,000 at the end of April.

President Donald Trump is expected to soon have more than 1 million tests a day, even 5 million a day in the context of the epidemic has not shown signs of cooling down and wants to reopen the economy.

Russia is the country with the later outbreak of epidemic. By mid-March, Russia had fewer than 100 cases, but that number increased rapidly in April, reaching 105,000 by the end of April.

Currently, according to SkyNews, Russia is speeding up testing with a capacity of 100,000 tests per day, including both public and private health systems. With over 3 million tests, Russia is the second largest country in the world after the US.

Germany is the first European country to conduct mass testing. With a capacity of over 350,000 tests a week, it allows Germany to perform more than 2.5 million tests. Along with the world’s best healthcare system, COVID-19 mortality rates in Germany are always low.

Other European countries severely affected by the COVID-19 epidemic, such as Italy, Spain, the United Kingdom and France, are undergoing mass testing in the hope of reducing the spread in the community when implemented. Social separation for nearly a month and is planning to reopen the economy.

Why is the world fighting pandemic by … testing and testing?
