In January 2020, a new type of coronavirus swept the world. Humans all over the world were instantly exposed to the attack of the new coronavirus. Countless people were infected with the new coronavirus. Some people left the world and bid farewell to their loved ones forever; some of the people healed smoothly after treatment, but still left some sequelae symptoms; others stay healthy but need to beware of the new crown virus at any time. …
Time goes back to the present. At the end of August 2021, the epidemic in China has gradually subsided, no new cases have appeared, and people’s lives have finally returned to normal. In the past few months, people have been infected with the new crown virus one after another. From the investigation of the behavior of these infected people, we can get a glimpse of their daily lives.
At the end of July, a young man in Jingzhou, Hubei was diagnosed with the new crown virus. His circulation report has become the focus of discussion in the past two days. The young man’s itinerary for these two days is shown in the figure below. In the past few days, the young man rode an electric car with his girlfriend to go shopping at the flower and bird market. He ate the rice noodles at the rice noodle shop. After being tired in the hotel, he went to the big pharmacy together. They also looked at the house, bought mosquito coils, and went to Jiuyang Road to get express delivery. They also went to eat barbecue together. The life of a pair of young lovers was shown before our eyes. At the end of July, the summer in Jingzhou, where the summer is strong. The itinerary of the young couple makes people sigh. It is convenient to travel by electric car.
Another story takes place in Wuhan. The protagonist’s itinerary is shown in the picture below. The protagonist of the story is named Tang, who is 21 years old this year. Tang first took the high-speed rail from Jingzhou to Hankou Railway Station, then took Metro Line 2 to Optics Valley to find his girlfriend Gan, and stayed at her home for one night. The next day, he left his girlfriend’s house and returned to the Wuhan University of Technology. Not long after arriving at school, Tang left the school again, and zoned Jianghan Road pedestrian street with girlfriend B, ate snail noodles, and went shopping together. In the evening, the two were separated, and Tang returned to his own home in the Wanjiahu community. Tang’s girlfriend Gan, after separating from him, went to Hankou College, drank a hundred Dao tea with friends, and ate McDonald’s. The next day she went to Optics Valley Financial Port, bought some things in a convenience store, and then returned to her home. In the evening, she came out to the street entrance, ate at Qunguang Plaza and Yintai Creative City, then took the subway to Wuchang Railway Station, and randomly took the train back to Xianning.
During the epidemic, the flow of confirmed cases was announced to the public about their life trajectories, so that the rest of the citizens can check whether they have been to these places recently. At the same time, it is convenient for the anti-epidemic personnel to draw the itinerary of the case and use techniques such as map analysis. Means to predict potential close contacts of cases, but also to help doctors discover the law of disease transmission. Graph Scope is a one-stop large-scale graph computing system researched by Alibaba’s Daruma Institute. It supports a variety of graph calculation and graph analysis algorithms, which can effectively help people analyze graphs and discover potential laws.
The epidemiological investigation of infected persons is also like a small window, allowing us to see what the daily lives of ordinary people like us are like. Some people go back and forth between different cities just to spend more time with their lovers. , Some people shuttled in the city, passing between multiple women, and others were still running to take care of their families and children one second before the diagnosis. The new coronavirus attack was like a sudden pause button. This has changed the trajectory of many people’s lives. I hope that mankind can develop an effective vaccine as soon as possible and that everyone can return to a healthy and free life before the epidemic.
