Which of the following is a category of disease identified in the public health framework?

• A. Infectious and parasitic
• B. Diabetes mellitus
• C. Asthma
• D. Neurological disorders

Answer: (A)

In public health, diseases are organized into broad categories to guide surveillance and prevention. One major category is infectious and parasitic diseases, which are caused by pathogens and can spread from person to person, from animals to humans, or via vectors. This grouping underpins key control measures such as vaccination, sanitation, infection prevention, vector control, and outbreak monitoring. The other options are specific conditions or types of non-communicable diseases, not broad categories used for population-level classification. Diabetes mellitus, asthma, and neurological disorders are important health topics within public health, but they are individual non-communicable conditions rather than a category used to classify diseases at the framework level. Therefore, the correct category is infectious and parasitic.
