as different As the countries, so too are the strategies with which the respective governments to contain the Coronavirus are want. Different health authorities rate about the asymptomatic Transmission. Usually Infected within five days of first symptoms. In exceptional cases, the incubation period can be up to three weeks.

According to the Chinese government, the number of “silent carriers”, i.e., the positively Tested, showing no or only symptoms may be delayed could be, at around 30 per cent, reports the South China Morning Post.

the Chinese Figures are Confirmed also by a group of Japanese experts under the direction of Hiroshi Nishiura, an epidemiologist at the University of Hokkaido. In the case of the Wuhan evacuated Japanese patients, the proportion of symptom-free Infected sun at 30.8 percent.

there is Much to indicate that “a significant number of cases, is under-diagnosed,” wrote the Japanese experts in a letter to the International Journal of Infectious Diseases.

These high Numbers stand in stark contrast to the statements of the WHO, what, asymptomatic Transmission is “extremely rare”. According to the WHO, asymptomatic infections in the European Union, only one to three percent of the cases.

Area-coverage Tests even without symptoms

In most European countries and in the United States, where only those with symptoms will be tested, the number of infections rapidly. In Germany, for example, is tested according to the Federal Ministry of health, only those who have flu-like symptoms AND in the last 14 days in a Region with a Coronavirus cases has stopped OR within the last 14 days contact to a confirmed Coronavirus case. Who is symptom-free and had contact with an Infected in Germany without a Test in a fourteen-day Self-quarantine sent, but hardly controlled.

In China and South Korea, the original SARS-CoV-2-Hotspots, the number of new infections are noticeably down. In the two countries everyone is tested, the close contact to an Infected had, regardless of whether it shows itself in symptoms.

Who was tested positive, quarantined and followed up by phone to be monitored, even if he shows no symptoms.

In South Korea are assigned to violations of the quarantine to date with a fine of up to 3 million Won ($2500). A new bill proposes to punish violators with a fine of 10 million Won and up to a year in prison.

Uncomplicated test options

After the rapid increase at the end of February, South Korea was able to reduce the number of new infections significantly. Currently nearly 9,000 of the approximately 50 million inhabitants are infected. Daily less than 100 infections will be added, 111 South Koreans have died from COVID-19.

in Many places, there are check points and tents, where everyone can quickly, easily and especially free of charge on the new Coronavirus tested. So far, have been carried out in South Korea, approximately 300,000 Tests. Per day around 15,000 inhabitants, can be tested, also thanks to the all over the country more than 40 of Drive-trough-corona test equipment, which have in the meantime also other countries downstream.

in Total, were tested in South Korea, in comparison to a lot more people than elsewhere, namely to 5.6 per 1000 inhabitants. For comparison: In Germany, around 160,000 Corona are carried out per week-Tests, equivalent to 1.9 per 1000 inhabitants. In the USA, so far a total of only around 30,000 Tests have been performed.

Successful containment policy

The containment succeeded in South Korea, without lock there is an output, and drastic travel restrictions gave. Although the public life is also massively down, and all should keep a distance from each other, but still the country does not want to make a complete seal. “South Korea is a democratic Republic. We believe that closures are not a sensible choice”, – quotes the journal Science, Kim Woo-Joo, a specialist in infectious diseases of the “Korea University”.

Instead, South Korea conducted “the world’s most extensive and best-organized test program, coupled with strong efforts to isolate infected persons, contacts, track, and quarantine,” – said in the Science article.

the extensive Tests were possibly discovered a lot of “silent carriers” in the vicinity of an Infected before they could infect more people. “Korea currently has a significantly higher Rate of asymptomatic cases as other countries, which is perhaps a result of our extensive testing,” said Jeong Eun-kyeong, Director of the Korean center for disease control and prevention (KCDC) last week.

Far-reaching powers of the government

in addition, South Korea has a profound effect on the privacy rights of its population. To minimize the risk of infection, will receive the citizen personalized information about the Corona-risk in your vicinity. The local authorities have access to detailed information about the Infected including their age, gender, and movement profile.

Since derMERS crisis of 2015, the government has the legal authority, including mobile phone and credit card to collect data in order to reconstruct the movement profiles of positively Tested. But entpersonaliserten data will also be given to Apps with which everyone can identify, whether he may have encountered an infected Person.
