Is it safe to travel on May 1st?
Travel experts of high-risk groups such as the elderly and pregnant women are not recommended to say that rising temperatures are not conducive to virus survival
At the press conference of the State Council ’s Joint Defense and Control Mechanism on April 23, a spokesman for the National Health and Health Commission Mi Feng said that as of 22:00 on the 22nd, there are 69 confirmed cases in Hubei, including two severe cases, all of which are Wuhan cases. For the first time, the number of confirmed cases nationwide has fallen to less than 1,000, and more than half of the confirmed cases imported abroad have been cured and discharged. However, the number of people diagnosed with clustered epidemic outbreaks in individual places is still increasing. It is necessary to block transmission channels as soon as possible, make up for loopholes in prevention and control, and resolutely curb the rebound of the epidemic.
At the meeting, relevant experts also introduced the popularization of scientific knowledge of the prevention and control of new coronary pneumonia.
Question one: Can you travel abroad during May Day?
According to Feng Luzhao, a researcher at the Chinese Center for Disease Control and Prevention, May 1 is approaching. For most areas where there is no recent case report, it is safe to travel, but there are still new overseas imported cases or local cases every day, so you must be vigilant , Be aware of the risk of contracting new coronary pneumonia.
He said that high-risk groups such as the elderly, patients with chronic diseases and pregnant women are not recommended to travel. "For travellers, pay attention to prevention and make preparations before traveling. It is recommended to travel near the wrong peak, try to avoid popular attractions or peak hours of attractions, and avoid carrying out some entertainment projects in confined spaces. If you plan to travel across regions, you should choose In areas where there is no recent case report, you should contact the scenic spot in advance to understand the local prevention and control policies, prepare as required, and also prepare some necessary masks, hand disinfectants and other items for use on the road. "
Doubt 2: How do you view the "source of Internet-borne virus"?
Shi Yi, a researcher at the Institute of Microbiology, Chinese Academy of Sciences, said that we have noticed relevant information on the Internet. Some people in the United States suspect that Fort Detrick Biochemical Research Base may be the source of the new coronavirus. The United States has no public response to this and we have no way to make a judgment. .
He said that virus tracing itself is a scientific issue. Judging from the whole process of scientific research on virus tracing, this is a scientific problem that takes a long time and there is uncertainty. "The current epidemic of new coronary pneumonia is raging globally. I hope that all countries in the world will focus their energy and attention on epidemic prevention. In the key control work, the scientific problem of virus tracing requires in-depth research by scientists from various countries. "
Question three: Will the epidemic be gradually suppressed as the temperature rises?
Shi Yi said that the new coronavirus is an enveloped virus, relatively speaking, it is relatively sensitive to temperature, and the increase in temperature is not conducive to the survival of the virus.
"We need to analyze and think about how the virus spreads, especially different virus spreads are not the same. Now we know that airborne viruses are relatively susceptible to temperature, which is why flu is generally at lower temperatures Is common in winter and spring, and is not common in summer. "
He said that it is now generally believed that the new coronavirus is mainly spread through droplets and direct contact. Relatively speaking, this method of transmission is less affected by temperature, and we also note that countries in the southern hemisphere are currently in summer and autumn. The weather is relatively hot, but the new crown epidemic continues to occur. The final situation, we need to observe further.
Question 4: Will the new corona virus become a normalized virus?
According to Shi Yi, as far as the actual situation is concerned, although China has made great efforts to effectively control the epidemic, "but as long as the epidemic exists in the world, the threat to humanity cannot be lifted. . "
He said that about whether the new coronavirus will be normalized and popularized like the flu virus, some experts believe that this possibility is there, but the probability of occurrence is relatively low. Is not very likely. "
He mentioned that some experts believe that the transmission capacity of the new coronavirus is high. Four coronaviruses have been seasonally epidemic, and there is a certain possibility that the new coronavirus will form a seasonal epidemic.
