| prevalence of bancroftian filariasis & its control by single course of diethyl carbamazine in a rural area in tamil nadu. | the prevalence of microfilaraemia, clinical spectrum of bancroftian filariasis and vector potential were studied in vettavalam village in north arcot district of tamil nadu. the effectiveness of selective therapy with diethyl carbamazine (dec) in controlling filariasis in rural areas was also evaluated. the prevalence of microfilaraemia (mf rate) and disease (disease rate) was found to be 11.7 and 11.09 per cent respectively. hydrocele was the dominant clinical sign in males and lymphoedema in f ... | 1989 | 2674003 |
| filarial/human immunodeficiency virus coinfection in urban southern india. | the disease course of human immunodeficiency virus (hiv) is often altered by existing or newly acquired coinfections. treatment or prevention of these concomitant infections often improves the quality and duration of life of hiv-infected persons. the impact of helminth infections on infections with hiv is less clear. however, hiv is frequently most problematic in areas where helminth infections are common. in advance of the widespread distribution of drugs for elimination of lymphatic filariasis ... | 2008 | 18840744 |
| usage of personal-protection measures against mosquitoes and the low prevalences of wuchereria bancrofti microfilaraemia in the indian city of chennai. | the usage of personal-protection measures against mosquitoes and the prevalence of wuchereria bancrofti microfilaraemia were assessed in different areas of the city of chennai, a large urban area in southern india. most of the households investigated (75% to 92%, depending on socio-economic status) used some form of personal protection (such as mosquito coils, vaporizing mats and liquids and mosquito nets). the study households spent a mean (s.d.) of 109.45 (141.65) indian rupees/month on person ... | 2008 | 18577330 |
| situation analysis in a large urban area of india, prior to launching a programme of mass drug administrations to eliminate lymphatic filariasis. | the main strategy now adopted for the elimination of lymphatic filariasis (lf) is based on mass drug administrations (mda). annual administration of antifilarial drugs to 65%-80% of the population at risk of the disease is believed to be necessary if lf is to be eliminated, at least as a public-health problem, within a reasonable time-frame. to facilitate the development of drug-delivery strategies that are sufficient to ensure such high treatment coverages in large urban areas, a situation anal ... | 2005 | 15829134 |
| use of floating layers of polystyrene beads to control populations of the filaria vector culex quinquefasciatus. | floating layers of polystyrene beads suffocate mosquito larvae and pupae and inhibit egg laying. the layers are very durable in breeding sites with water contained within walls, as in wet pit latrines and soakage pits. in some areas such pits constitute an important breeding site for culex quinquefasciatus. trials have been conducted in communities in zanzibar, tanzania, and in tamil nadu, india, where such mosquito populations were the vectors of wuchereria bancrofti. in each case, treatment of ... | 2002 | 12625923 |
| the influence of the mass administration of diethylcarbamazine, alone or with albendazole, on the prevalence of filarial antigenaemia. | the current indian campaign for the elimination of lymphatic filariasis is largely based on mass drug administration (mda). as part of this campaign, villagers in the tirukoilur and mugaiyur 'blocks' (i.e. revenue units) of villupuram district, in tamil nadu, india, were treated with diethylcarbamazine (dec), either alone (mugaiyur) or with albendazole (tirukoilur), in march 2001. the efficacy of treatment, in each of the two treatment arms, was evaluated by determining the percentages of the su ... | 2002 | 12396322 |
