ABSTRACT
The aim of the present investigation was to assess the filarial transmission levels in houses of different structure in rural areas of Andhra Pradesh, India. During this study, ecologically-similar households were selected for entomological study. The per-man-hour density (PMHD), infection and infectivity rates, were recorded in different ranges ie, 16.1 to 77.6, 0-31.2% and 0-5.6%, respectively.

Night mass blood surveys were carried out for parasitological evidence of Bancroftian filariasis in 45 rural areas belonging to 9 National Filaria Control Program (NFCP) zones of East Godavari and West Godavari districts of Andhra Pradesh, India during the period 1998 to 2001. Mf prevalence range between 2.9 to 10.2%, and mf intensities in 20 mm3 blood samples ranged from 1-281. The present study explains the trend of microfilaria dynamics in the rural population, where mass drug delivery has been implemented since 1997, and anti-larivicidal and adulticidal control measures have not been adopted.

This paper describes the seasonal abundance of Culex quinquefasciatus in the rural and urban areas of the East and West Godavari districts (EGDT and WGDT) of Andhra Pradesh, India. The per man-hour density (PMHD) was collected from seven units in EGDT and two units in WGDT, which comprised rural and urban areas. The highest infection and infectivity rates were found in the rural areas of Rajahmundry (43.6%) and Amalapuram (13.2%) respectively. In urban areas, the highest infection and infectivity rates were found in Rajahmundry: 7.5% and 3.6% respectively. There was considerable difference in the infection rate and infectivity rates between the rural areas and urban areas in each unit.
