The Taiwan Centers for Disease Control and Prevention (CDC) reported today that it received a report from a hospital in October 2022 that an influenza type A virus of which no subtype could be determined was isolated from the respiratory sample of a 7-year-old girl with mild infection. The influenza that lived in central Taiwan, which was tested and sequenced by the department as the H1N2v influenza virus.
After the investigation, there were 6 contacts of the case, two of whom had flu-like symptoms, and no H1N2v influenza virus infection was found. After the agricultural management unit and relevant medical experts were called for a meeting to discuss, based on the results of the current epidemiological investigations mentioned above, the case was judged to be a sporadic case, similar to the previous international cases. There is no evidence of human-to-human transmission. Health and agricultural authorities will continue to strengthen human, animal and environmental monitoring.
The CDC says this is a Second case of H1N2v influenza virus in the country.
The patient had no recent travel history abroad, and his family is engaged in poultry farming. On September 24 of this year, he developed symptoms such as fever, muscle aches, loss of appetite, cough, and runny nose. , On September 26, he went to the doctor because of a high fever. The COVID-19 rapid test was negative and the influenza rapid test was positive for type A. After a doctor’s evaluation, he did not require hospitalization. He returned home after being prescribed antiviral medications for influenza and recovered.
The CDC also noted that H1N2v influenza virus was isolated from the girl’s respiratory tract sample on October 18, and tests for viruses common in respiratory infections such as adenovirus, respiratory fusion virus, enterovirus, and rhinovirus were all negative. . In addition, the Agricultural Management Unit also collected swine samples in the pig farm run by the case family, and the results showed that no H1N2 influenza virus was detected. In response to the second confirmed case in my country, the Centers for Disease Control and Prevention will simultaneously notify the World Health Organization through the IHR contact window.
According to the Centers for Disease Control and Prevention, the first case of H1N2v type A flu was detected in my country in April last year (2021). She was a 5-year-old girl who lived in the central region. The source of feed and pigs, the slaughterhouse where the livestock are raised, the route of the mode of transmission, and the virus gene are all different, and the two cases are defined as unrelated.
H1N2v is a low-virulence influenza virus found in pigs, and there have been occasional cases of human infection, most of which are mild. Since 2011, there have been at least 45 confirmed cases of H1N2v influenza in the world, with 41 cases in the Americas. Most cases have a history of contact with pigs or exposure to polluted environments. There is no case of infection by eating meat. The genetic sequence of the virus isolated from the patient this time is similar to the H1N2 virus strain isolated from pigs in the past, but not the same. He is sensitive to current publicly funded influenza drugs.
