This is a case of H3N2 and H10N5 co-infection, a 63-year-old from Xuancheng, Anhui Province, who has a history of multiple underlying medical conditions. On November 30, 2023, he developed symptoms such as cough, sore throat, and fever, but unfortunately passed away on December 20, 2023 due to his worsening condition. In the course of a retrospective study of the fatal cases, the seasonal H3N2 subtype and avian H10N5 subtype influenza viruses were isolated from case specimens in Zhejiang Province on January 22, 2024. The Chinese Center for Disease Control and Prevention conducted a review and testing of the specimens submitted for testing in Zhejiang, and the results were consistent with the previous ones. At present, Zhejiang and Anhui provinces have conducted medical observation on all close contacts, and no abnormalities have been found, and the nucleic acid screening is negative; Through a retrospective case search, no suspicious cases were identified during the same period.
In the face of such a rare co-infection of the virus, we must re-examine the transmission and prevention and control of influenza, and take scientific and effective measures to avoid the recurrence of the virus.
First, we need to strengthen public awareness of influenza prevention and control. Popularize the prevention, prevention and knowledge of influenza through various channels, so that the public can understand the dangers of influenza and prevention and control measures, so as to enhance their awareness of self-protection.
Second, we need to do a good job in case surveillance and tracing the source. For any suspected case, testing and traceability should be carried out in a timely manner so that the virus can be grasped in a timely manner** and the route of transmission. At the same time, we need to strengthen cooperation between medical institutions and disease control agencies to ensure timely reporting and effective handling of cases.
Third, we need to strengthen immune protection against the virus. At present, vaccines against H3N2 and H10N5 viruses are on the market, and we should actively vaccinate to improve our own immunity and resistance and reduce the risk of infection.
Fourth, we need to do a good job of cultivating personal hygiene habits. Maintaining good personal hygiene, such as washing hands frequently, wearing masks, and avoiding crowded places, are important measures to prevent viral infection. At the same time, we also need to avoid contact with wild animals and game meat to reduce the transmission of the virus.
Finally, we need to strengthen international cooperation. In the face of the global threat of infectious diseases, we need to strengthen international cooperation and share information, technology and resources to jointly address the challenges of the pandemic.
In addition, we need to pay attention to some details. For example, keep an appropriate distance in public places and avoid close contact; Cover your mouth and nose with a tissue when coughing or sneezing; After touching public objects, wash your hands with hand sanitizer and running water in a timely manner. These details may seem trivial, but they can effectively reduce the risk of contracting the virus.
In short, in the face of rare cases of co-infection of the virus, we must strengthen scientific prevention and control and take various measures to avoid the recurrence of the virus. Only through the joint efforts of the whole society can we defeat the epidemic and ensure the health and safety of the people.
