Public health measures for patients diagnosed with typhoid fever to prevent outbreaks include prompt case identification and notification to public health authorities to enable timely outbreak control and contact tracing . Patients should be advised on strict personal hygiene practices, especially thorough handwashing with soap after using the toilet and before handling food, to reduce faecal-oral transmission . Isolation or exclusion from food handling and healthcare work until confirmed non-infectious is essential to prevent spread in community and institutional settings . Environmental sanitation measures, including safe disposal of human waste and ensuring access to clean water, are critical to interrupt transmission chains . Health education campaigns targeting patients and their contacts should emphasise the importance of hygiene and safe food and water consumption . Screening and treatment of asymptomatic carriers, particularly food handlers, may be necessary to prevent ongoing transmission . Antimicrobial stewardship is important to reduce resistance development, ensuring appropriate antibiotic use guided by susceptibility testing . Vaccination strategies may be considered in endemic areas or for close contacts to reduce outbreak risk . Together, these integrated measures form a comprehensive public health response to control typhoid fever outbreaks effectively.
