Leishmaniasis is caused by parasites of the genus Leishmania transmitted by sand flies. It manifests as visceral leishmaniasis (Kala azar), cutaneous leishmaniasis, mucocutaneous leishmaniasis, and post-kala azar dermal leishmaniasis. India has a high burden, with over 130 million people at risk of Kala azar. Control measures include treatment of cases, vector control through indoor spraying, and health education. Dengue is caused by dengue viruses transmitted by Aedes aegypti mosquitoes. It affects urban and peri-urban areas in tropical regions, with cases increasing dramatically globally in recent decades.
