Acute Communicable Disease Control
Hansen Disease (Leprosy)
This chronic infectious disease usually affects the skin and peripheral nerves but
has a wide range of possible clinical manifestations. Patients are classified as
having paucibacillary or multibacillary Hansen's disease. Paucibacillary Hansen's
disease is milder and characterized by one or more hypopigmented skin macules.
Multibacillary Hansen's disease is associated with symmetric skin lesions, nodules,
plaques, thickened dermis, and frequent involvement of the nasal mucosa resulting in
nasal congestion and epistaxis.
