Even as India sets its sights on elimination of kala azar by the end of this year, incidence of a little-known skin condition that is a red flag for transmission of the disease has been growing — in fact, it has more than doubled in the last year, and trebled in the last two.

PKDL brings what looks like many other skin lesions but this lesion houses the kala-azar parasite, Leishmania donovani. The lesion, being the only symptom, is often ignored while the person afflicted continues to act as a reservoir for kala-azar infection. Kala-azar, which in India is spread by L donovani alone, infects the reticulo endothelial system — a network of cells and tissues found throughout the body, especially in the blood, general connective tissue, spleen, liver, lungs,bone marrow, and lymph nodes.

There is an increased urgency the world over to eliminate kala-azar, partly because of its association with HIV. Visceral leishmaniasis, as kala-azar is otherwise known, is an opportunistic infection (like TB) in HIV and other infections that cause suppression of the immune mechanism. However, it is not a very serious problem in India yet, according to the National Vector Borne Disease Control Programme.
