[Technical guidelines for seasonal influenza vaccination in China, 2019-2020].
Influenza virus infection is a respiratory infectious disease that can seriously affect human health. Influenza viruses can have antigenic variation and changes frequently, which results in rapid and widespread transmission resulting in annual epidemics and outbreaks in population gathering places such as schools, kindergartens and nursing homes. WHO estimated that seasonal influenza epidemics could cause 3 to 5 million severe cases annually, and 290 000 to 650 000 deaths globally. ⋯ Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for use by staff members of the CDCs at all levels who work on influenza control and prevention, PoVs staff members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and staff members of maternity and child care institutions at all levels. These guidelines will be updated periodically as new evidence becomes available.
