Scenario 1: There is currently no cure or vaccine for the new virus. The official order is that experiments can only be carried out in the BLS-4 laboratory, and no other laboratory can study it anymore, "I don't want to see this virus sticking to the soles of anyone's shoes and leaving the laboratory." However, a professor in the BLS-3 laboratory insisted on secret research and made breakthrough results.
Relevant expertise: Biosafety level 4 laboratory is a better and safer laboratory than biosafety level 3 laboratory. Preventing the spread of this unknown new virus with high lethality in the laboratory is also very important in biological experiments. important part.
My opinion: I agree with the practice of government officials forbidding the BLS-3 laboratory to conduct experiments on the virus, but I disagree with the practice of the old professor who insists on secret research. The foundation of all experiments is based on the safety of oneself and others. At that time, the emergency was related to whether many people's lives could be saved, and it was also related to the problem of virus leakage in the laboratory. Like the famous train derailment problem, choosing either side can have bad results, but unlike the train derailment problem, there may be a more appropriate solution in this case. Professors can give experimental ideas to scientific researchers in the BLS-4 laboratory, or they can temporarily apply to enter the BLS-4 laboratory for research. Of course, this is just my humble opinion, and the specific regulations need to be further understood.
Scenario 2: A man was suspected of having indirect contact with the deceased heroine ten days ago and wondered whether he was infected. The doctor told him that the incubation period of the virus was much less than 10 days, so don't worry.
Expertise: The incubation period refers to the period from when a pathogen invades the human body to the earliest clinical symptoms appear. Different incubation periods are of different lengths, with some diseases as short as a few hours and others as long as several years. But the same infectious disease has a fixed incubation period.
Episode 3: There has been a new breakthrough in vaccine research, and multiple animal and human trials are needed, but the situation is not waiting for anyone. Dr. Hextall did a test on himself, and the results showed that the vaccine has the effect of preventing the virus. Then major pharmaceutical companies started production, and the virus crisis was solved.
Professional knowledge: Vaccines refer to biological products made from various pathogenic microorganisms for vaccination. The development of a vaccine is a long and complex process, and it is costly. Due to the consideration of various side effects and effects, vaccines need to go through a long process from initial development to actual clinical use, especially the steps of human experiments are very complex and rigorous.
My opinion: I admire Dr. Hextall's approach in the movie. She blocked her own life in order to quickly break the current dead end. Fortunately, she succeeded in the bet. What if she didn't? What we lose is a good scientist. Regarding this issue, I have always lacked a position. On the one hand, I believe that procedural justice cannot be violated, and on the other hand, I am influenced by the kindness of doctors. If I were in Dr. Hextall's position, what would I choose? Maybe I will submit the first vaccine products I have developed to wait for human trials, and then use what I have learned to protect myself from being infected within a few months; maybe I will believe in myself and fate like her, and block everything on my own. Seek a possible turnaround for the public; maybe?
Episode 4: After losing his wife and young son, Thomas has only one daughter left. The daughter is not infected with the virus. He wants to try his best to protect her daughter, so he does not let her daughter come into contact with anyone outside, so as not to be infected. My daughter really wanted to meet her boyfriend, and finally, a few months later, they hugged and danced together at home after being vaccinated.
Expertise: The route of transmission is the process in which pathogens are excreted from the source of infection and reach and invade new susceptible individuals through a certain mode of transmission. The transmission routes of pathogens are: airborne, waterborne, foodborne, contact transmission, arthropod transmission, soil transmission, vertical transmission, iatrogenic transmission, etc.
My opinion: Thomas is right. The best way to protect her daughter from pathogens is to isolate the source of infection and cut off the route of transmission.
Episode 5: A self-proclaimed "reporter" spreads "forsythia can cure infectious viruses" on the Internet, and the public believes him and goes to drugstores to snap up forsythia.
Expertise: The efficacy of each drug needs to be carefully controlled and tested, and it is not the case that a suspected infection is "cured" by a drug to prove that the drug is effective. (If this logic is used, can it be said that the water that dissolves the forsythia cured the "reporter"?)
My opinion: The reporter's so-called infectious disease treatment experiment is: I think I have symptoms of infection with the virus, so I drank forsythia-dissolved water, and the next day I felt that I had "recovered health". An experiment so imprecise and full of loopholes has been watched and blindly believed by millions of people. Now that we have reached the age of science, there are still so many people who may be out of hatred for the government or have no scientific literacy themselves. I believe that a blog post that is illogical is something worth thinking about in itself. The government's repeated emphasis that "there is no evidence that forsythia can cure the infectious disease" does not do much, and a so-called "journalist" can attract so many people with a random blog post. Concern and trust, what kind of sadness is this?
