As summer gets started, what do I need to do to travel? How to choose a hotel to be assured? The weather is getting hotter and hotter, do you still want to wear a mask? ...... Today (June 19) afternoon, Professor Wu Fan, Vice President of Shanghai Medical College of Fudan University and Dean of Shanghai Institute of Major Infectious Diseases and Biosafety, opened a lecture at the Shanghai University of Science popularization.
She "leads by example" by saying that she travels with her "three-piece suit" — bath towels, slippers and cups. Good personal hygiene can greatly reduce the chance of infection.
"The large number of traceable data shows that most of the infected people are infected through contact rather than air, so there is no need to worry too much about the air in the hotel." Wu Fan suggested that after staying in a hotel room, you can use alcohol cotton pads to wipe the door handle and the toilet door handle, which are the easiest places for your hands to touch.
Summer is also the peak of international students' entry, while doing a good job of personal protection, we must not forget the disinfection of luggage. Wu Fan said that the new crown virus can survive for three days at room temperature, and the new crown virus is most likely to be contaminated on the surface of the suitcase, after checking into the hotel, you can open the suitcase and try not to touch the surface of the suitcase. Leave it in the hotel's dry air for three days and die even if the surface is contaminated with the virus.
"The new crown virus is afraid of ultraviolet rays, and the easier way is to put the suitcase in a ventilated place to dry, which can basically kill the virus." She said.
Since China entered the normalization of epidemic prevention and control, the domestic epidemic situation has tended to be stable, but some areas still show different degrees of sporadic and punctate disease characteristics. In the face of the "getting smarter" new crown virus, Wu Fan reminded everyone not to let down their vigilance - masks, social distancing, personal hygiene, and the "three-piece set" of epidemic prevention can not be less.
Wu Fan cited data from the paper published in The Lancet that following social distancing of more than 1 meter, the probability of infection can be reduced from 12.8% to 2.6%; wearing a mask, the probability of infection can be reduced from 17.4% to 3.1%; eye protection, the probability of infection can be reduced from 16.0% to 5.5%.
What should I do if the weather is getting hotter and the mask is getting more and more "can't be worn"? Wu Fan reminded everyone that the incubation period of the new crown virus is 0 to 14 days. Patients have been detoxified in large quantities 2 to 4 days before the onset of symptoms, which is highly contagious. In cases where it is not possible to tell if there is an infection, wearing a mask is an important defensive measure. "Once a fever occurs, be sure to go to the hospital for examination to rule out the risk of COVID-19 infection." She said.
Also, keep your hands washed frequently. Washing your hands with soap for more than 20 seconds and rinsing with running water is the correct posture for hand washing. Wu Fan repeatedly reminded everyone that soap can destroy the virus and make it lose its ability to infect, the more bubbles the soap, the better the effect, to resist the new crown, washing hands is no less important than wearing a mask.
This lecture is the first time that the Shanghai Science Popularization Forum has tried to connect the Inner Mongolia Natural History Museum, Shaoxing Science and Technology Museum and Yancheng Science and Technology Museum at the same time after successfully connecting the Tibet Natural Science Museum and the Xinjiang Science and Technology Museum for many times, using network live broadcast technology to break the time and space restrictions, realize the cross-domain linkage live broadcast and audience interaction of the six places, and create a new situation of co-construction and integration of science education and the common sharing of the new crown prevention and control.
