The Preventive and Promotive Health Directorate focuses on proactive measures to promote health, prevent diseases, and improve overall well-being. This directorate emphasizes interventions and strategies that aim to keep individuals and communities healthy, rather than solely focusing on treating illnesses. This includes organizing immunization campaigns, conducting disease awareness programs, and implementing measures to control outbreaks.

It also actively monitors the occurrence of diseases within the County, an exercise which involves collecting and analyzing health data to identify trends, outbreaks, and emerging health threats. Timely surveillance helps in preventing the spread of communicable diseases and implementing effective interventions. Additionally County public health departments play a crucial role in preparing for and responding to public health emergencies and disasters by developing response plans, coordinating with other agencies, and ensuring that healthcare facilities are equipped to handle emergencies.
