Multiple pathogens are prevalent, beware of mixed infection! Beijing flu peak may come earlier

Beijing has entered the high-incidence season for respiratory infectious diseases, showing a trend of multiple pathogens co-prevalent . At present, influenza is in the epidemic period, and the number of cases is increasing rapidly. On November 21, the Beijing Center for Disease Control and Prevention reminded citizens to take good personal protection, actively get vaccinated, and build a good immune barrier.

Wang Quanyi, deputy director of the Municipal Center for Disease Control and Prevention and chief epidemiologist, said that based on the outpatient visits at the Children's Hospital and the Institute of Children's Research, the prevalence of Mycoplasma pneumoniae has dropped to fourth place among children's respiratory infectious diseases, with influenza, adenovirus, and respiratory syncytial virus ranking the top three. In addition, based on the results of respiratory pathogen monitoring, the top three reported cases of respiratory infectious diseases in the city's entire population are influenza, rhinovirus, and respiratory syncytial virus .

The city has established the most comprehensive influenza surveillance system in the world. All first-level and above hospitals in the city report influenza-like cases, and 39 sentinel hospitals conduct etiological surveillance, with a large sample size and reliable results.

According to monitoring, the incidence of influenza is currently on the rise. At present, the positive rate of influenza virus nucleic acid in influenza-like cases in outpatient clinics has risen to 40.75%.

Wang Quanyi introduced that the influenza is currently in the epidemic period, which is earlier than in previous years, indicating that this year's epidemic peak will also arrive earlier than in previous years. The number of cases of Mycoplasma pneumoniae infection is on a downward trend. The main epidemic strain of the new coronavirus is the XBB variant, which continues to maintain a low epidemic level. Due to the co-prevalence of multiple pathogens, the overall number of infections will show an upward trend, which may lead to a longer high plateau period and an increase in medical demand. Medical institutions should be prepared to cope with the pressure.

"People who have been infected with one respiratory infectious disease may also be infected with other types, resulting in mixed infection or successive infection. Don't let your guard down." Wang Quanyi specifically reminded that in the process of protecting against respiratory infectious diseases, special attention should be paid to the prevention of multiple diseases . Try to avoid crowded places with high infection risks, and wear masks scientifically when taking public transportation or going to crowded public places.

At the same time, key groups and key places should be protected . Schools and childcare institutions should do a good job in daily prevention and control, focusing on ventilation and cleaning, supplemented by preventive disinfection, and strictly implement morning and afternoon inspections, registration and reporting of absences due to illness, etc., to reduce the risk of clustered epidemics. Nursing homes should actively organize the elderly and relevant staff to receive relevant vaccines such as the new crown and influenza, reduce visits from outsiders as much as possible, and ensure that visitors wear masks and other protective measures.

In addition, the main influenza strain currently is the influenza A H3N2 subtype . According to sequencing analysis, this subtype matches the vaccine well, and the vaccine can provide better protection for the vaccine recipients. Wang Quanyi called on citizens, especially the elderly, patients with underlying diseases and other key groups, to actively get vaccinated and take good protection.

Pre-diagnosis testing! Many pediatric departments in Beijing hospitals have implemented

Respiratory infectious diseases are prevalent in autumn and winter. Recently, the pediatric departments of Beijing Tiantan Hospital, Chaoyang Hospital, Friendship Hospital and many other hospitals have begun to implement the "test before diagnosis and treatment" measure to streamline the process, shorten waiting time, reduce the number of trips to and from the clinic, and reduce the risk of cross-infection in the hospital. At present, 242 hospitals in the city can provide Internet diagnosis and treatment services, and children with milder conditions can try Internet treatment.

"Register - wait in line for consultation - doctor sees and issues auxiliary examination form - pay - wait in line for examination and test - wait in line again for doctor to read report - complete diagnosis and treatment", this is the "traditional" medical treatment process familiar to parents. Recently, the Department of Pediatrics of Beijing Tiantan Hospital began to implement the "test first, then diagnosis and treatment" measure. When young patients with fever and cough symptoms come to the hospital, they can apply for blood routine, Mycoplasma pneumoniae and other tests in advance at the pre-examination and triage office, and complete routine tests at the inspection window while waiting for consultation. The test results can be directly provided to the doctor during the consultation. "It's great, when the results come out, it's time to call the number, and the efficiency of medical treatment has really improved!" said a parent who just took his child to see a doctor.

"At present, 'pre-diagnosis testing' is first for children with fever and cough symptoms. In the future, we will combine the diagnosis and treatment routine, continuously expand the scope of services, and provide more routine pre-diagnosis testing services for young patients." Wang Yajie, deputy director of the Department of Pediatrics at Beijing Tiantan Hospital, said that "testing first and then diagnosis and treatment" is a service measure launched to alleviate the increase in patients with respiratory infectious diseases in autumn and winter, and it is also another new measure for the hospital to improve the quality of medical services. In addition to Beijing Tiantan Hospital, Beijing Chaoyang Hospital and Friendship Hospital have also taken corresponding measures. Starting this month, Beijing Chaoyang Hospital has also adopted the measure of "testing first and then diagnosis and treatment" in the Department of Pediatrics of Changying Campus. After children with fever and cough report at the self-service machine, they can first go to the specific pediatric clinic to evaluate their condition, issue pre-diagnosis test orders such as blood routine and Mycoplasma pneumoniae, and use the waiting time to conduct relevant tests and examinations in advance before consulting. After the consultation, patients can complete the medication at the self-service machine in the pediatric clinic area. "Most children only need to wait for one consultation to complete the diagnosis and treatment, which effectively shortens the consultation time and reduces the chance of cross-infection in the hospital." The relevant person in charge of the hospital said. The Beijing Friendship Hospital's Pediatrics Department has set up a dedicated person to issue a checkup form for children before seeing a doctor, shortening the process of seeing a doctor and reducing waiting time. Currently, 242 hospitals in the city have launched Internet diagnosis and treatment services. Recently, the pediatric clinics of hospitals are generally crowded. Friendship Hospital and other medical institutions remind that children with mild illnesses can choose Internet diagnosis and treatment methods for consultation and diagnosis of their illnesses.
