The following treatment measures can be used for influenza virus infection in children: First, children should be given anti-influenza medications, such as oseltamivir or paramivir, both of which have anti-influenza virus effects. Secondly, children should be treated with symptomatic support, such as hydration and oral rehydration salts, especially oral rehydration salts, which can effectively replace the loss of water and electrolytes due to high fever. Finally, children can be given antipyretic drugs. If a child with influenza virus infection has an axillary temperature of 38.5℃ or higher, it is necessary to apply antipyretic drugs such as ibuprofen to reduce fever in a timely manner.
