Zhang Wenhong: The infectious disease challenge is not only the new crown, the immediate goal is to do this well

This past weekend, the first National Center for Infectious Diseases, Infection Cooperation Forum and the first Oriental ID week were held in Shanghai.

As the "head" of the National Center for Infectious Diseases, Professor Zhang Wenhong invited authoritative experts and scholars from various fields in China to attend the conference.

On the afternoon of April 2, during the coffee break of the meeting, Professor Zhang Wenhong took time to accept an interview with a reporter from Xinmin Evening News.

"The scale of the conference is very large, and there are many forums, which is also because the infectious disciplines are rich in connotation and require interdisciplinary and cross-field cooperation and exchanges." Zhang Wenhong was straight to the point and pointed out the original intention of this meeting. He told reporters that most ordinary people's understanding of infectious diseases is still only in the new crown epidemic, in fact, the work of infection doctors also includes many aspects. "In addition to the uncertain challenges of emerging infectious diseases, bacterial drug resistance, and the risk of infection from tumors, transplants, etc. will also become the norm. Unlike general infections, the control of drug-resistant bacteria is a major clinical challenge. ”

As early as 2020, when the epidemic had just broken out, Professor Zhang Wenhong said in an interview, "When the curtain of the new crown falls, I will walk away very quietly." Everyone should chase dramas and chase dramas, what should they do. "Today, people have indeed returned to business as usual, and the impact of the new crown epidemic has gradually dissipated, but throughout the history of human development, various infectious diseases have never stopped appearing, so clinicians, public health workers, and scientific and technological workers have not completely "walked away", but their eyes have slowly moved away from the new crown, and the focus has become to improve their ability to deal with the long-term challenges of various infections and infectious diseases and the uncertain challenges of the future pandemic.

He said that after the establishment of the National Medical Center for Infectious Diseases, the construction of pathogenic diagnosis capabilities has been further strengthened and the construction of clinical research capabilities has been accelerated. In addition, it has fully cooperated with the disease control system to carry out various research and clinical work on the elimination of chronic infectious diseases, and build disciplinary capacity in the clinical practice of eliminating chronic infectious diseases.

The immediate goal is to always prepare the clinical treatment force of infection and infectious diseases, and establish a high-level public health clinical team that combines peacetime and wartime and adapts to the development of future disciplines. The "war" needs to mobilize all medical forces and test the emergency response ability and diagnosis and treatment ability of public medical institutions, especially grassroots medical and health institutions, to emerging and major infectious diseases. In peacetime, it is necessary to reserve more scientific and technological forces, including vaccines, testing, public health measures, etc., to promote the integration of medical and prevention, create a three-level system of clinical treatment, promote the establishment of a graded diagnosis and treatment system and a consultation and referral system, and build an ecological environment for win-win cooperation on infectious diseases.

The Oriental International Infectious Diseases Academic Week will end on April 6. After that, Professor Zhang Wenhong will also put more energy into daily clinical research work, and continue to promote tuberculosis, viral hepatitis and other projects. In the face of everyone's concern about whether the new crown epidemic will continue to epidemic, Professor Zhang Wenhong said frankly that local epidemics caused by virus mutations will still occur, but the public health challenges we face are not only the new crown, so we need to use the big platform of the national center to explore the new development pattern in the field of infection.

Expert: This round of flu peak has basically passed

On March 29, the National Influenza Center released the "China Influenza Surveillance Weekly Report" for the 12th week of 2023, which showed that the positive rate of influenza virus tests in southern provinces slowed down this week, while the northern provinces continued to decline. A total of 683 influenza-like outbreaks were reported this week. The reporter combed through the "China Influenza Surveillance Weekly" released since 2023 and found that this week achieved the first decline since the release of influenza-like case data.

"Clinically, this data is basically consistent with the number of patient visits we have observed clinically. In the past two weeks, our flu patients have shown a clear downward trend compared to previous weeks. On April 2, Xia Ammongdong, deputy chief physician of the Department of Infectious Diseases and Hepatology of the First People's Hospital of Yunnan Province, told reporters that as the number of people diagnosed with influenza declined, the peak of this round of influenza should have passed.

Chen Guolin, deputy director of the Department of Infectious Diseases of the First Affiliated Hospital of Harbin Medical University, also told reporters, "From a clinical point of view, in the past 10 days, the number of new influenza patients who came to the hospital has indeed decreased, and this round of influenza peak has basically passed, but as the weather warms, we must begin to pay attention to the occurrence of digestive tract infectious diseases, such as bacterial dysentery, typhoid fever, etc., everyone should still pay attention to dietary hygiene, wash hands before meals and after using the toilet, avoid raw food, cooked food and raw food knives, cutting boards separately." ”

"As the temperature gradually warms, everyone should pay more attention to norovirus infection, infectious diarrhea, etc., and still pay attention to hand hygiene, dietary hygiene, etc., to avoid digestive diseases." Xia Ammonium Dong also pointed out.

How long do I have to wear a mask?

Wu Zunyou spoke up

On April 2, Wu Zunyou, chief expert in epidemiology at the Chinese Center for Disease Control and Prevention, posted on his Weibo on questions such as "how long should masks be worn, what occasions should you insist on wearing them, and what occasions you can not wear them".

The main contents are as follows:

Wearing masks is mainly considered from the perspective of protecting health, especially to prevent the epidemic of respiratory infectious diseases such as new crown and influenza.

Let's take a look at the current situation. The Chinese Center for Disease Control and Prevention has published the latest epidemic information on its website as of March 30, 2023. On March 30, the number of positive nucleic acid tests reported nationwide per day has dropped to less than 3,000, back to the epidemic level of October 2022. People who report positive nucleic acid tests daily nationwide are basically detected by active testing, and they are people who have not "impotent" during the national epidemic. The number of deaths from the new coronavirus infection in hospitals was zero last week and has been zero for several weeks. It can be said that this wave has basically ended.

According to the global coronavirus epidemic reported by the World Health Organization as of March 29, 2023, the number of weekly reported new crown cases worldwide has dropped below 100,000 cases for the first time since March 2020; For the first time, the number of weekly coronavirus deaths reported globally fell below 1,000. Both the number of cases and the number of deaths have fallen to their lowest point since the pandemic. This set of data heralds the end of the global pandemic.

The flu season is coming to an end. Judging from the surveillance of influenza-like cases in sentinel hospitals nationwide published by the Chinese Center for Disease Control and Prevention, influenza epidemic has stabilized in the past three weeks. As the weather warms, the number of flu cases will fall further.

In such a pandemic context, how should we wear masks.

There are currently no unified regulations on wearing masks in all localities, departments, and units. Therefore, be sure to carry a spare mask with you at all times.

For occasions where masks are explicitly required, such as participating in meetings, the organizer of the meeting requires everyone to wear masks, or passengers are still required to wear masks when taking public transportation, and the regulations are followed.

Access to special institutions or places, such as homes for the elderly, especially those that have not experienced an epidemic during the national epidemic, must comply with the relevant regulations of the institution or venue regarding wearing masks.

For occasions where masks are not explicitly required, such as entering and leaving hotels, shopping malls, taking buses or subways, you can decide whether to wear a mask on your own or without a specific requirement.

In crowded and poorly ventilated scenes, such as places where medical institutions visit, it is recommended to wear masks.

Masks are recommended for outdoor activities in dusty weather or severe air pollution.

People with respiratory symptoms such as fever or cough are advised to wear a mask.

Families with elderly people or children or people with low resistance are recommended to wear masks if colleagues have respiratory symptoms such as cough and fever.

In spacious places such as parks, streets, and communities, masks can be dispensed with.

Wear masks reasonably to protect your and my health.
