202 1 can I travel with peace of mind during the Spring Festival holiday on New Year's Day? Is the tour safe?

After the autumn and winter seasons, there have been some sporadic epidemics all over the country. Although it didn't cause large-scale spread, it still made everyone nervous. It is the peak of the Spring Festival holiday on New Year's Day. So is it safe to travel during the Spring Festival holiday on 202 1 New Year's Day?

Sporadic outbreaks have occurred in many places. Since May 438+February in early June, the temperature in most parts of the country has continued to drop, and sporadic epidemics have occurred in many parts of the country.

In less than half a month, there have been confirmed cases and asymptomatic infection cases in Jiaozhou, Shandong, Chengdu, Sichuan, Manzhouli, Dongning, Suifenhe and Turpan, Xinjiang.

Is it safe to go out on New Year's Day and Spring Festival? Wu Zunyou, the chief expert of epidemiology at China CDC, reminded the public in an interview with the media a few days ago that in places where epidemics have already occurred, the probability of recurrence in winter is greater. However, this does not mean that there will be no epidemic in other places, and all places involving foreign people and things may have epidemics.

He emphasized that since the winter, the epidemic situation in COVID-19 has risen sharply in most countries except China, and the number of infected people and contaminated articles has increased. There has been increased pressure on domestic anti-imports, anti-people and anti-matter. In this global context, sporadic cases have appeared in China, which is a normal phenomenon of normalization of prevention and control.

Regarding the risk of epidemic spread during the Spring Festival, Ceng Guang, a member of National Health Commission high-level expert group and former chief scientist of China CDC, said that there was a large-scale personnel flow during the National Day this year, which was considered as a stress test. Facts have proved that as long as the prevention and control measures are appropriate, the risks can be completely controlled.

However, experts stressed that the situation during the Spring Festival is different. On the one hand, the scale of population movement during Spring Festival travel rush was much larger than that during the National Day holiday. On the other hand, the lower the temperature in winter, the longer the virus will survive. In addition, people will visit relatives and friends on holidays, and large-scale indoor gatherings will also increase the risk of epidemic spread in COVID-19, so the risk of epidemic prevention and control during the Spring Festival will definitely increase.

Ceng Guang believes that although there is a large flow of people during the Spring Festival, as long as there are no infected people in the crowd, there will be no large-scale epidemic. From this perspective, it is no problem for everyone to go home for the Spring Festival. However, during the Spring Festival this year, it is absolutely forbidden to visit each other or gather indoors on a large scale.

Why does the epidemic happen again in the epidemic area? Wu Zunyou, chief epidemiologist of China CDC: Generally speaking, in places where an epidemic has already occurred, the probability of another epidemic in winter will be greater than in other places.

However, this does not mean that there will be no epidemic in other places, and all places involving foreign people and things may have epidemics.

Difficulties in winter prevention and control Wu Zunyou, chief expert of epidemiology at China CDC: In cold winter, especially when the temperature is very low, it will be difficult to carry out epidemiological investigation.

There are two main aspects of epidemiological investigation: one is face-to-face investigation between people, which is a classic and traditional way to ask patients and close contacts where they have been in the past and who they have contacted.

Second, people's memory may not be so complete, and they can clearly remember everything in the past, which requires modern technology, including recordable information such as mobile phone code scanning.

Therefore, when the temperature is extremely low in winter, the functions of these new technical means such as mobile phones will be affected, which may have some impact on epidemiological survey data, especially the assistance of big data.
