"A-Mei held 12 concerts at the Taipei Arena in April this year. However, it has been reported that more than 16 people have been diagnosed and 39,154 cellular newsletters have been sent out. The Epidemic Command Center urges people to reduce unnecessary movement, activities or gatherings, avoid crowded places or places with high risk of infection transmission, and proactively cooperate with the epidemic prevention measures to guard the community's defense line. The domestic epidemic continues to expand, with a surge of 874 local cases on April 14, and since April 1, the number of local cases has exceeded 5,300 in two weeks. On April 15, the Epidemic Command Center announced that there were 1,209 new cases of endemic disease in 19 counties and cities, another record high. The public complained that the existing epidemic prevention policy, the "Real Linkage System", is cumbersome and ineffective, and even expanded due to the recent dangerous local epidemic, causing more people to avoid using the system to avoid being affected. The Epidemic Command Center is actively promoting the "Taiwan Social Distance App", which is intended to replace the real-linkage system in the future. As long as the public has the App and stays in a place for more than 2 minutes, they can be exempted from scanning the real-linkage system, which is currently based on the principle of encouragement and publicity, but does not rule out the possibility of a mandatory requirement according to the law. The United Kingdom also use social distance App, data found that every 1% more users to download the use of App, the epidemic will fall 1%, therefore, when the epidemic is growing rapidly really need to use technology to prevent the epidemic.
