ABSTRACT
Mosquito-borne diseases, including malaria, Japanese encephalitis (JE), lymphatic filariasis and dengue, are major public health concerns in the north-eastern state of Assam, deterring equitable socioeconomic and industrial development. Among these, malaria and JE are the predominant infections and are spread across the state. The incidence of malaria is, however, gradually receding, with a consistent decline in cases over the past few years, although entry and spread of artemisinin-resistant Plasmodium falciparum remains a real threat in the country. JE, formerly endemic in upper Assam, is currently spreading fast across the state, with confirmed cases and a high case-fatality rate affecting all ages. Lymphatic filariasisis is prevalent but its distribution is confined to a few districts and disease transmission is steadily declining. Dengue has recently invaded the state, with a large concentration of cases in Guwahati city that are spreading to suburban areas. Control of these diseases requires robust disease surveillance and integrated vector management on a sustained basis, ensuring universal coverage of evidence-based key interventions based on sound epidemiological data. This paper aims to present a comprehensive review of the status of vectorborne diseases in Assam and to address the key challenges.

A 30 year-old farmer presented himself with mild degree fever, joint pain and multiple ulcers of 15 days' duration. Ulcers were multiple, well-defined, irregular in shape with necrotic base and elevated, sloppy margins over anus, forearms, wrists, buttocks, lower half of thighs and shins. A few of the ulcers were covered with black-coloured scab. They were tender and with serosanguinous discharge. Black atrophic scars and ill-defined, irregular, brown black-pigmented macules of various sizes were present over thighs and legs. Excision biopsy of the ulcer showed features of erythema nodosum leprosum. The patient was treated with systemic corticosteroids.

A 40-year male lepromatous leprosy patient presented with four, slightly erythematous patches, with multiple urticaria-like wheals, distributed over the body symmetrically and with thickened right ulnar and right common peroneal nerves. He was previously diagnosed as a case of chronic idiopathic urticaria. Slit skin smear from the patches and urticarial wheals showed a BI of 3+ and skin biopsy showed some features of borderline lepromatous leprosy (BL).
