Shanghai’s anti-epidemic hero Zhang Wenhong finally spoke out. What important information did he reveal?

Zhang Wenhong, director of the National Medical Center for Infectious Diseases and director of the Department of Infectious Diseases at Fudan University Affiliated Hospital, gave a 30-minute report at the Chinese Academic Conference, analyzing relevant data and the pattern of the epidemic in my country. changes, we finally came to the conclusion that now Omicron has had an evasion effect on our antibodies, and the vaccine is still a very effective protective measure. ?The characteristics of Omicron have shifted and evolved

This wave of epidemic in Shanghai has made people re-understand Omicron and re-examined the transmission ability of the epidemic, warning us that Don't take it lightly, because the epidemic may come back as soon as the situation is relaxed.

Omicron spreads very quickly. According to expert calculations, the basic reproduction number (R0) of Omicron is now equal to 9.5, which means that one person can infect 9.5 people. This spread The ability of Omicron is actually very terrifying, exceeding that of chickenpox. Therefore, experts believe that the current transmission ability and speed of Omicron are difficult to control, which is why the epidemic in Shanghai has lasted for so long.

Although Omicron spreads quickly, its symptoms are often not as severe as before. For example, there were many common symptoms in Delta, such as headaches, fever and other very obvious symptoms. , now the symptoms of Omicron have become very mild, and many people don’t even have obvious symptoms. I have a classmate studying in Japan. She was infected with Omicron more than a month ago, and she just feels a little weak. But my throat hurts so much that it hurts even more to speak.

Aggravation of upper respiratory tract infection is actually a sign of deviation of Omicron. Currently, many people infected with Omicron have main symptoms such as sore throat, hoarseness, weakness and muscle pain, etc. , what Professor Zhang Wenhong said about the deviation of Omicron is actually this point. ?The new coronavirus is not the same as the big flu

In fact, many people around us believe that the new coronavirus is a flu with more severe symptoms. Nowadays, science popularization is very timely. Many people know that after being infected with Omicron, systemic inflammation will occur. The symptoms are even milder than the common flu, so there's a temptation to be more open-minded.

Professor Zhang Wenhong also explained this. He said that although the degree of inflammation after infection with Omicron is lighter than that of influenza, if the patient is older and has more underlying diseases, then the infection Later inflammation problems may cause the patient to die.

In fact, many people do not feel that our country has now officially entered the stage of aging society, and it is not far away from super-aging.

International standards believe that when the population is over 60 years old and accounts for 10% of the total population, or when the population is over 65 years old and accounts for 7% of the total population, it is classified as an aging society. The elderly people over 65 years old account for 14 of the total number, which is a deeply aging society, with 20 people over 65 years old. It is a super-aging society.

At present, our country is already a deeply aging society. Some experts estimate that by 2050, our country’s elderly population will account for one-third of the total population, which is more than 30 years old.

There is a large elderly population, and the overall economy still lags behind that of developed countries. If we open up hastily, the consequences will be unimaginable. Therefore, vaccines are still very effective, especially in reducing severe illness and death. rate aspect. ?The protective effect of vaccines is still very strong, especially for the elderly

Professor Zhang Wenhong mentioned in the report that compared with some countries with good vaccination status, the protection of the elderly by vaccination is The effect is indeed there.

The professor pointed out that Australia’s vaccination situation is relatively good. Like South Korea, the penetration rate is relatively high, and the mortality rate is basically maintained between 0.09 and 0.1.

It is also pointed out that the vaccination situation in Singapore is also very high. The vaccination rate for people over 80 years old exceeds 80, and its mortality rate is around 0.1. The same is true for New Zealand, because the vaccination rate for people over 65 years old is The vaccination rate has reached 98, and its fatality rate is only 0.08.

It can be seen that vaccines are still one of the best means of epidemic prevention at the moment, so vaccines will continue to be covered in the coming period. ?Non-drug intervention will continue for some time

Many people do not understand what drug intervention is. Professor Zhang Wenhong gave a detailed explanation in his speech. He pointed out that non-drug intervention is what we use every day in our lives. Contact travel code testing, wearing masks, nucleic acid testing and other methods can help prevent the spread of the epidemic.

In fact, nucleic acid testing is now very popular. If you want to go out or come back from other places, you can get a nucleic acid test in advance. It won’t take too long, and the price is very cheap.

Take our eighteenth-tier cities as an example. There are many places to do accounting, some are free and some are paid. They are usually on the small roads connecting cities. The checkpoints are made free of charge and at designated points in the city. Local nucleic acid is only 4 yuan. After the test is completed, it is synchronized to the mobile phone through big data. It is very convenient for us to take it when traveling.

Nowadays, with the popularity of self-examination, it is very likely that in the future we will be able to check ourselves at home, without delaying our schedule and without wasting time. We will even prepare some self-examination at the door during family gatherings in the future. Items that produce results in a few minutes are a kind of protection for yourself and others.

At present, the international community is exploring this kind of home testing solution. After all, large-scale nucleic acid testing is a waste of time and inconvenient, and nucleic acid is one of the best methods to control the spread of the disease. ?Written at the end

Professor Zhang Wenhong finally mentioned in the comparison that the epidemic is likely to not end in a short time, and requires all of us to have better patience and more courage.

Indeed, the epidemic has had a more or less huge impact on our lives in recent years. Students who have graduated from school in the past few years, as well as family members who are in long-distance relationships, as well as those who have worked hard in other places for several years The impact on young people who have not been home for many years is not small. Some people have not even been able to go home to see their loved ones even after their relatives passed away, just because of the epidemic.

Although we don’t know when it will end, I would like to say that we should not be pessimistic. After all, specific drugs are being developed in various countries, and the proportion of asymptomatic infections is increasing, and the situation of severe cases is getting worse. lower, the future is still full of hope.
