Bacterial pneumonia can cause sudden high fever and convulsions. Typically, the fever lasts about three to five days. In patients with weak immunity, the fever may persist for seven to ten days. Decisions should be made based on the amount of bacteria in the body and the immune capacity. It's important to adjust your mindset, understand correctly, and seek early detection and treatment. Maintaining appropriate indoor temperature and humidity is crucial. When feverish, it's necessary to measure body temperature. If it does not exceed 38 degrees Celsius, oral antipyretic medications generally aren't necessary; physical methods to reduce fever can be used to relieve discomfort.
