More "Homes": The U.S. Can Get Away With Coronavirus Disease

On March 26 from 9 am to 10:30 am Eastern Time, Zhang Wenhong, leader of the Coronavirus disease pneumonia expert team in Shanghai Medical Treatment and Director of the Infection Department of Huashan Hospital Affiliated to Fudan University, was invited by the Chinese Embassy in the United States to focus on coronavirus disease pneumonia. The outbreak was carried out on a global live link.

Zhang Wenhong, an expert from the Shanghai New Coronavirus Pneumonia Treatment Team, answered questions about the new coronavirus infection ways, the US and world epidemic development, the proportion of critical illnesses, medical resources, how important is wearing a mask, how to prevent infection, and how to do it after infection Handling, etc. 

Zhang Wenhong said that when the U.S. epidemic reached its peak and the "inflection point" after it ushered in, it depends on the state's emergency response, especially the implementation of the "home order." For the whole pneumonia outbreak of new coronavirus infection to usher in a transition or an individual to avoid infection as soon as possible, "home" is very important. Trying to stay at home, not gathering, washing hands frequently is the best way to deal with pneumonia outbreak of new coronavirus infection.

Zhang Wenhong said that the situation in New York State in the United States is severe, but in fact, the more cases there are, the more tests there are, but sufficient test capabilities. The eastern United States has missed the best time to suppress novel coronavirus (COVID-19) epidemic. The place with more than 300 cases in the Salt Lake City area is the best time to suppress community transmission. While the novel coronavirus (COVID-19) epidemic is developing in the United States, the detection speed is very fast, showing the scientific and technological strength of the United States; rapid detection can inhibit the spread of disease. The reason why the United States has more young people is because the social situation in the United States (including many European countries) is that older people generally only go to work, home, and places to buy daily necessities, but young people do not wear There are many masks and social activities, so it is easy to be infected.

Pneumonia outbreak of new coronavirus infection has a critical illness rate of about 20%, extremely severe disease is about 5%, and 80% of infected people can get through by themselves; severe illness requires oxygen therapy, and extremely severe illness may require intubation. How to be infected and have fever and other symptoms. Eating more eggs, milk, rest and vitamin C at home is the best way; but if you feel difficulty breathing, breathing up stairs, etc., go to the emergency department. Room for medical help. The number of ICU beds in the United States is among the highest in the world, so even if you get new coronary pneumonia in the United States and develop serious illness, you can get good treatment without worrying.

Zhang Wenhong said that it is normal for anti-coronavirus in US states to be out of sync early. But the United States has the best medical team in the world, and people should be confident. Some time ago, Shanghai ’s epidemic prevention and control mainly focused on identifying carriers from Wuhan. Now Maryland is also adopting this approach, instead of completely “blocking” like Wuhan; the former approach has less impact on life. Different countries have adopted different methods to control the epidemic situation. Mainland China is determined to "isolate", Singapore focuses on "testing", and South Korea has done a good job of isolation and testing. These were quickly brought under control. The existing medical resources and production capacity of the United States are very strong. For example, the New York ventilator is now fully equipped and is still being mobilized and produced; how long the epidemic can be controlled depends on which prevention and control method is adopted; the US government will adopt The most appropriate policy, they know where their limits are.

Zhang Wenhong also said that many states in the United States have now issued "home orders", requiring stores and restaurants to close, people to maintain "social distance" and so on. The "Home Order" is well executed. Maybe the United States will usher in the peak of coronavirus disease outbreak in 10-14 days, and then it will be the inflection point; once the inflection point comes, things will develop well. However, if the implementation is not good enough, the peak will come slower, which may take 4 weeks; in this case, the number of confirmed cases will still increase exponentially within 4 weeks, which may cause a shortage of medical resources, which is more worrying. Try to stay at home, not party, wash hands frequently, this is the best way to deal with the new coronavirus pneumonia. During the epidemic, "house" was a great advantage.

Zhang Wenhong also answered many "details" questions from international students and Chinese representatives. For example, although it seems that airborne transmission is not the mainstream and close contact, if you are really worried about "elevator transmission", you can take the method of pressing the elevator button through a tissue or a toothpick. Also, even if the insurance for foreign students is the cheapest and simplest, it will also include treatment for new coronary pneumonia, but if you really encounter a difficult situation, you can ask the embassy for help. If you decide to return to your country, the possibility of contagion in the confined space of the aircraft is indeed greater, and the greatest risk is before boarding; but in fact, the "triple protection" of protective clothing, N95 masks, and goggles is unnecessary, and N95 masks are sufficient. Tertiary protection is only needed when medical staff face a huge viral load and aerosol transmission occurs during intubation. When you receive the mail, you can remove the outer packaging of the mail and set the oven at about 60 degrees for 40 minutes to prevent the virus from spreading. This novel coronavirus (COVID-19) epidemic may not end in summer. It must continue into winter. Drugs such as Lianhuaqingwen capsules can be used when they are needed most. As for the currently effective "chloroquine", there is no proof. Any kind of special medicine for coronavirus disease pneumonia, so do not take or hoard when you are not sick.

Zhang Wenhong finally stressed that he has confidence in the US health system and that emergency resources can keep up. As long as everyone "homes" before the peak, do not party, wash their hands and reduce social interaction, there will be no major problems. Historically, from influenza to SARS to Ebola, the human epidemic has not been defeated once. As for the duration of the epidemic, it depends on the country with the worst control, not the country with the best control.
