China News Service, January 31. According to the website of the National Administration of Disease Control and Prevention, the National Administration of Disease Control and Prevention reported that a case of H3N2 and H10N5 mixed infection was discovered in Zhejiang Province.
The patient is a 63-year-old female from Xuancheng, Anhui Province. She has multiple underlying diseases in the past. Symptoms such as cough, sore throat, and fever developed on November 30, 2023; on December 2, he was admitted to a local medical institution for treatment due to his worsening condition; on December 7, he was transferred to a medical institution in Zhejiang Province for hospitalization. Died on the 16th. During a retrospective study of fatal cases, Zhejiang Province isolated seasonal H3N2 subtype and avian H10N5 subtype influenza viruses from case specimens on January 22, 2024. On January 26, the China Centers for Disease Control and Prevention conducted a re-examination and testing of specimens submitted for inspection in Zhejiang, and the results were consistent with previous results. Zhejiang and Anhui provinces have conducted medical observation on all close contacts, and no abnormalities were found, and nucleic acid screening was negative; through retrospective case searches, no suspicious cases were found during the same period.
The National Administration of Disease Control and Prevention has guided Zhejiang and Anhui provinces to carry out prevention and control in accordance with relevant plans and organized experts to conduct risk assessments. Experts assessed that the complete genetic analysis of the virus showed that the H10N5 virus was of poultry origin and did not have the ability to effectively infect humans. The epidemic was an occasional cross-species transmission from poultry to humans. The risk of the virus infecting humans is low and no human-to-human transmission has occurred.
Experts suggest that the public should avoid contact with sick and dead poultry in daily life and try to avoid direct contact with live poultry; pay attention to dietary hygiene and improve self-protection awareness. If you have fever and respiratory symptoms, you should wear a mask and seek medical treatment as soon as possible.
