Preventing fever in cancer patients involves several strategies aimed at reducing the risk of infection and managing the side effects of cancer treatments. Some measures include: - Strict adherence to infection control practices, such as hand hygiene and avoiding contact with sick individuals. - Prophylactic antibiotics or antifungals in high-risk patients. - Regular monitoring of blood counts to identify and address neutropenia early. - Vaccinations, such as the flu shot, to protect against specific infections.
