Leishmaniasis. Flashcards
What issue?
(1) Organism Type: Obligate intracellular protozoan parasites
(2) Prevalence: 700,000-1.2M new cases each year; found in over 90
countries in the tropics, subtropics, & southern EU. On every continent except Australia & Antarctica.
(3) Predisposing Factors: Chronic sand fly exposure, poverty, proximity to dogs/cats/rodents.
(4) Transmitted Via: Bite of infected female phlebotomine sand flies

- Yes
The most common manifestation of Leishmaniasis is ________________, which is characterized by_________________.
Cutaneous Leishmaniasis, gradual-onset cutaneous
lesions.
True/False
Normal sand fly bite reactions are pruritic but do not enlarge and resolve after several weeks
True
What issue
Differs from normal sand fly bites:
(a) Begin as a pink colored papule that enlarges to a nodule or plaque-like lesion.
(b) Lesion ulcerates with indurated border and may have thick white-yellow fibrous material.
(c) Lesions are often painless
(3) Multiple lesions may be present
(4) Lesions gradually heal over months to years with noticeable scarring at site.
CL
Clinicians should maintain a high suspicion for CL in any patient with __________________ that has been to an area where CL is endemic & the patient reports a history of sandfly bites.
chronic (nonhealing) skin lesions
CL – Treatment
IDC Treatment/first-line interventions:
(a) Ulcer should be debrided and kept clean to avoid secondary
infections from developing.
(b) Bandaged & wrapped to avoid further wound contamination
True/ FAlse
CL – Treatment
Any lesion with high suspicion for CL can be managed at the idc level
False
should be turfed to MO and/or MTF Infectious Disease dept as soon as operationally allowable. CL is not lethal; however, it does require care far beyond the IDC.
The foundation of leishmaniasis prevention is what?
the avoidance of being bitten by sand flies in endemic areas.
