Wuhan Pneumonia Storm “Southern China is about to enter flu season Expert: May be mixed with new coronavirus infection!

The development of the pneumonia (new coronavirus pneumoniae) epidemic in Wuhan, China has entered a critical period. All parties look forward to the “inflection point”, but disease control experts warn that the southern cities with severe outbreaks are about to enter the season of high seasonal influenza. Mixed infection of the two viruses may Interference in the prevention and control of new coronavirus epidemics. According to the Guangzhou Daily, a public health expert from Guangzhou 11 published in the Chinese Journal of Preventive Medicine on the occasion of “against the epidemic of new coronavirus pneumonia while guarding against seasonal influenza.” “Effects” article pointed out that the severely infected southern cities are about to enter the season of high seasonal influenza. It is necessary to strengthen epidemiological investigations, optimize laboratory testing strategies, take effective measures to increase the intensity of influenza epidemic prevention and control, and minimize interference with the prevention and control of new coronavirus epidemics. Influenza virus, parainfluenza virus, adenovirus, respiratory syncytial virus … According to the disease surveillance data, other respiratory infectious diseases that are about to enter the epidemic season, such as influenza virus, parainfluenza virus, adenovirus, respiratory syncytial virus, rhinovirus, human metapneumovirus and other related diseases, their clinical manifestations are similar to those of new coronavirus pneumonia There are similarities that are difficult to distinguish by clinical manifestations and chest imaging. These respiratory viruses are mixed in the current new coronavirus pneumonia epidemic, which interferes with the prevention and control of the epidemic, and a slight laxity in prevention and control can cause emergencies. Therefore, from the perspective of public health, it is also very important to identify and prevent these respiratory viruses. Corresponding author Wang Ming emphasized: “Among them, the influenza virus needs to alert us particularly.” At least 1 person per 10 person in flu season Influenza viruses are highly contagious, spread rapidly, and have a global epidemic, which can cause serious complications and lead to death. According to the World Health Organization (WHO), influenza can cause 5% to 10% of adults and 20% to 30% of children become ill, resulting in 65 10,000 deaths. This shows that during the flu season, at least one in every 10 individual is infected with the flu. The peak season of influenza epidemic in China shows a north-south difference, with northern regions appearing in autumn and winter and southern regions appearing in spring and summer. At present, the provinces with severe outbreaks of the new type of coronavirus in China are mainly concentrated in the south, such as cities in Hubei, Guangdong, Zhejiang, Hunan and other provinces. These cities are about to enter the season of high influenza, which is expected to continue until July to August. Judging from the recent trend of the new coronavirus epidemic, the performance is inconsistent across regions, and the epidemic situation in some regions is difficult to end in a short time. Its epidemic trend is likely to be integrated into the influenza season, which means that more fever cases will be monitored and the cases will be identified Work and difficulty will increase further. If fever cases cannot be detected in a timely manner in the laboratory, influenza cases are likely to be treated as new coronavirus infections, which will adversely affect the prevention and control of new coronaviruses. Experts reviewing the data during SARS found that from late January to mid February 2003, Guangzhou SARS entered a stage of rapid increase in cases, and the positive rate of influenza virus isolation in cases of fever and cough / pharyngeal pain during the same period was 5 %, The positive rate of influenza virus isolation in the SARS epidemic year was 13%. In addition, serological surveys during the 2009 year A H1N1 epidemic also proved that 3. 27% of confirmed cases of H1N1 influenza A were also infected with seasonal influenza . Influenza vaccination can still “fix the dead” The author believes that, on the one hand, test kits that integrate new coronavirus and common respiratory viruses should be developed as soon as possible, which can be convenient, fast, and suitable for popularization at the grassroots level; relevant departments should emphasize laboratory quality control in clinical and disease control departments, such as Ensure that the detection reagents used have good sensitivity and specificity, prevent laboratory contamination, etc., and minimize misdiagnosis, missed diagnosis and late diagnosis. On the other hand, it is necessary to strengthen the epidemiological investigation, classify and manage suspicious cases, and prioritize them to ensure that key cases can be promptly investigated. Furthermore, in view of the importance of influenza prevention and control, in order to minimize the incidence of influenza in the population and to alleviate the confounding and interference of new coronavirus prevention and control, the feasibility and possibility of promoting influenza vaccination can still be explored. Especially in the southern cities, the flu epidemic peaks in the spring and summer seasons. According to the law of antibody production after vaccination, flu vaccination still has the effect of “repairing the dead sheep”, which is also very beneficial to the overall epidemic prevention and control in the future.
