How did COVID-19 spread around the world?

The path of the new pneumonia spreading around the world can only be imagined at present. Its infection route is divided into four lines, which are detailed below:

1. China Line: Unknown Source of Infection-Wuhan - Nationwide.

This route in China has a relatively long infection duration. Although after SARS was diagnosed at that time, the growth rate was scary, but the first 100,000 people infected by the new crown in the world took 67 In one day, China accounted for more than 80,000. In other words, in fact, our country bought more than two months for the rest of the world regarding this virus. During this period, we controlled traffic, self-isolated, and concentrated all the patients as much as possible. It has been systematized.

It can be said that our country encountered test questions that exceeded the stipulations, but it still submitted an answer sheet with a score of no less than 90 points with the efforts of the whole country. This epidemic coincides with the Spring Festival in my country. If it were at any other time, our number of infections would be even lower.

2. Asian line: Unknown source of infection (suspected to be the United States) - people in Japan and South Korea.

The COVID-19 epidemics in Japan and South Korea began 20 days after my country closed its cities. According to the sources of infection they found, the first batch of COVID-19 patients had nothing to do with Wuhan, and there were no my country's contact history; however, when Japan investigated the source, it found a history of contact with the United States and suspected that the United States was the source of infection. Later, as Korean citizens went out, other countries did not take as strict precautions as we did, and it quickly spread throughout Asia. North Korea has always been in a state of lockdown and has not been affected.

3. American Line: American Influenza Transformation - All of the United States - Americas.

At the beginning, the new coronavirus epidemic in the Americas was confused with the influenza in the United States. No nucleic acid testing was performed at all for the same symptoms, and some people even died of the disease without being diagnosed. The United States did not take the new crown seriously at the beginning, and there was no isolation or control. Most companies were at work, and various entertainment centers were open. As a result, after the outbreak, the number increased by tens of thousands.

The United States is the most developed in all aspects in the entire Americas. Among the countries in the Americas, the United States leads the epidemic prevention track. Before the United States declared that it had entered a state of epidemic prevention, other countries did not take any action; until the United States After announcing that they were entering epidemic prevention and control, countries such as Brazil, Canada, and Mexico began to take precautions. However, due to the transmission ability of the new crown, the spread may have already spread. The specific follow-up will depend on subsequent reports.

4. European line: Unknown source of infection-Iran-Italy-all Europe.

In the Italian investigation report, their epidemic was introduced from Iran. Because it took the new coronavirus lightly, Italy became the most serious country abroad, and some people died without even being diagnosed; because Italy Due to the lack of strict control and the intensive contact between European countries, the epidemic began to spread rapidly throughout Europe, and because medical equipment and supplies could not keep up, there were already actions to grab supplies among European countries; in addition, the United Kingdom and Sweden allowed the virus to spread, which was a great obstacle to the prevention and control of the new coronavirus.

The new coronavirus is a worldwide epidemic in 2020. Its true source has not yet been found, but judging from the data, it is definitely not our country’s fault!
