In both Brazilian and American medical contexts, high fever is taken seriously as a symptom warranting medical attention. In Brazil, it's common for people to consult a doctor (médico) or pharmacist for fever management. Americans often use over-the-counter fever reducers and may consult a doctor if the fever persists beyond 24-48 hours. The threshold for concern is typically the same in both cultures.
