Autochthonous dermal leishmaniasis in Texas.
The American Journal of Tropical Medicine and Hygiene
|November 1, 1976
Summary
Two Texas residents contracted dermal leishmaniasis, a skin infection caused by Leishmania parasites. Investigations suggest local transmission in south-central Texas, indicating the disease may be endemic.
Area of Science:
- Medical Entomology
- Parasitology
- Epidemiology
Background:
- Dermal leishmaniasis is a parasitic skin disease caused by Leishmania.
- Cases in Texas are rare, prompting investigation into local transmission.
Observation:
- Two biopsy- and culture-positive cases of dermal leishmaniasis were identified in southern Texas between 1972 and 1974.
- One patient showed positive serologic tests for Leishmania infection.
- Leishmania infection was also detected in a neighbor and three dogs near one case.
Findings:
- Epidemiologic and serologic data suggest local acquisition of infection in both patients.
- No direct link was found between the two human cases.
- The presence of potential reservoirs and vectors in the area supports local transmission.
Implications:
- These findings suggest that dermal leishmaniasis may be endemic in south-central Texas.
- Further research is warranted to identify specific reservoirs and vectors.
- Enhanced surveillance may be necessary to monitor and control potential outbreaks.
