Study Notes

Kala-azar Seasonal Prevalence

There are two peaks of kala-azar cases, one in November and another in March-April.
High prevalence is observed during and after periods of rain.

Kala-azar Transmission

Kala-azar transmission is influenced by climate changes in rainfall, temperature, and humidity.
Blood transfusions can transmit kala-azar.
Contaminated syringes and needles are another route of transmission.

Clinical Features of Cutaneous Leishmaniasis

Cutaneous leishmaniasis presents as a skin infection.
The disease can be mistaken for leprosy.

Laboratory Diagnosis of Leishmaniasis

The Leishmanin (Montenegro) test is used to diagnose leishmaniasis.
This test is based on skin reaction.

Prevention of Leishmaniasis

Insect repellents (lotions, creams, or sticks) are used for personal protection against leishmaniasis transmitting insects.
There are no drugs available for personal prophylaxis against leishmaniasis.
