First, it is important to rest in bed during the acute phase, drink plenty of water, keep warm, and the main principle is to control the infection and provide symptomatic treatment. For instance, patients with significant fever and those whose sputum has turned purulent should choose antibiotics early, such as intramuscular penicillin injections or oral co-trimoxazole. Generally, the medication can be stopped 1-3 days after the fever subsides. For symptomatic treatment, antipyretic analgesics such as aspirin can be used to address symptoms like fever, headache, and general fatigue. Regularly, one should strengthen their cold resistance through exercise, it is suggested to wash the face with cold water throughout the year, and to exercise more to boost immune capabilities. Pay attention to environmental hygiene, improve occupational and public health standards. Prevent the inhalation of irritant gases and dust into the respiratory tract. (Medication should be used under the guidance of a doctor based on specific circumstances.)
