A group of 20 people from Kunming traveled to Lanzhou, and 4 of them were positive. What measures have the relevant departments taken?

All of them have been isolated in Lanzhou Hotel, and Lanzhou has also released the tour route in time, and is looking for close contacts. A tour group from Kunming traveled to Lanzhou. On the way back, the driver of the tour group said that for the safety of themselves and their families, everyone should collectively do a nucleic acid test before going home. The driver spontaneously organized passengers to go to the hospital for nucleic acid testing, and four passengers reported positive results. In order to make a further diagnosis, they adopted a single-tube test method, and finally identified four positive patients. Even if they were arranged to go to the hospital for isolation, the rest were arranged to be isolated in Lanzhou Hotel.

Lanzhou also released the news at the first time. Correspondingly, if there is a way for people to consciously isolate their homes in these places, if there are close contacts, take the initiative to report. After this incident, the first thing we need to think about is, where did the infectious hospital come from? They didn't carry out nucleic acid test when they left Kunming, so it is possible that the passengers on the bus were infected with COVID-19 from the beginning, or there were COVID-19 patients in Lanzhou, which led to the passengers being infected. In short, Lanzhou should control the flow of people.

Since COVID-19 swept the world, we have been very worried about being infected by this virus. Although we have all been vaccinated with COVID-19 vaccine, the epidemic prevention of foreign viruses is not ideal. With the research of medical staff on COVID-19, we can cure him now, so don't panic too much. In fact, the biggest impact that COVID-19 has brought us is the inconvenience of travel and the difficulty of employment. Because of COVID-19, countries are strictly guarding against the import and export of goods, which makes many enterprises lose their export business. But they don't need much at home, which leads to the company's production reduction and layoffs. The company itself is laying off employees, so naturally it won't recruit new ones. So many graduates have not found suitable jobs in the past two years.

The above is my own opinion.
