Patients with milder influenza A will be treated with antiviral therapy for about 5-7 days, and isolated for about 2-3 days after the symptoms are relieved; patients with severe symptoms of influenza A need to be treated for more than 15 days, such as severe pneumonia that can easily cause respiratory failure, and there is a risk of death due to respiratory failure, and patients must be admitted to the intensive care unit to give ventilator-assisted breathing.
