Which of the following diseases was part of the Expanded Programme on Immunization?

The Expanded Programme on Immunization (EPI) was initiated by the World Health Organization to increase vaccination coverage and combat the prevalence of specific vaccine-preventable diseases in children. Among the diseases included in the EPI are those that typically cause significant morbidity and mortality, particularly in young populations.

Measles is one of the diseases included in the EPI. The inclusion of measles in the EPI is significant due to the highly contagious nature of the disease and the serious complications it can cause, including pneumonia, encephalitis, and even death. The measles vaccine has been instrumental in reducing the incidence of the disease globally, making it a crucial aspect of public health initiatives aimed at improving child health outcomes.

Other diseases listed, like typhoid fever and hepatitis A, do not have routine inclusion in the EPI schedule, mainly because they are not as universally critical in early childhood vaccination targets as measles, mumps, or rubella. These diseases may be addressed at a national level through specific campaigns or vaccination protocols but are not part of the core vaccines promoted by the EPI to ensure widespread immunity in children globally. Thus, the focus on measles within the EPI reinforces the program's aim to effectively control and eliminate vaccine-pre
