The effect of the bancroftian filariasis on the health of the inhabitants are minimal in the study area, where the prevalence of the disease (nocturnal microfilaremia) is 0.4% only. But skin snips harboring Onchocerca microfilariae are seen in 12.1% of the sample studied. Onchocerciasis skin lesions, low visual acuity and blindness are often seen in the villages where the prevalence is high, among inhabitants more than 40 years of age. Simulium damnosum is seldom seen in the area, except in the large streams and rivers like the mayo Tsanaga and the mayo Djingliya. Larvae and nymphae of this species hardly succeed in developing on the overspelling of the small dams, this being due more to a discontinuous run of the water in the overspilling than to a to high speed of the water.

Lymphatic filariasis transmission 10 years after stopping mass drug administration in the Gomoa West District of Ghana.

Department of Parasitology, Noguchi Memorial Institute for Medical Research, College of Health Sciences, University of Ghana, Accra, Ghana. Electronic address:
Objectives: A survey was conducted 10 years after stopping MDA in the Gomoa West District of Ghana to assess the Wuchereria bancrofti prevalence in both human and mosquito populations.
Methods: In seven communities, infection in humans was assessed using the filariasis test strip (FTS). Mosquitoes were collected once a month over six months using pyrethrum spray catches (PSC).
Filarial parasite infection prevalence in field-caught mosquitoes from Connecticut, United States.

Filarial nematodes are parasitic roundworms transmitted by mosquitoes that can cause morbidity and mortality for their human and animal hosts. The filariae community, specifically infection prevalence of heartworm, Dirofilaria immitis (Filarioidea: Onchocercidae) (Leidy), and its primary mosquito vector species, has not been described in Connecticut since 1977. In light of the recent invasion and establishment of an important filariasis vector, Aedes albopictus (Diptera: Culicidae) (Skuse), we used molecular-based sequencing methods to identify filarial species infecting field-caught mosquitoes in Connecticut, United States.

Objective: Sierra Leone, a country where onchocerciasis is endemic in 14 of the 16 districts, was the focus of our investigation. Despite 17 rounds of annual ivermectin treatment since 2005, a report circulated by a local politician indicated an increase in cases of suspected onchocerciasis-related vision impairment in two villages (Mangobo and Petifu) in Tonkolili district. In response, the National Neglected Tropical Disease Program conducted a comprehensive investigation.

Centre for Clinical Research, The University of Queensland, Brisbane, QLD, Australia.
Background: Lymphatic filariasis (LF), a mosquito-borne parasitic disease caused by three species of filarial worms, was first detected in Niue, a small Pacific Island nation of approximately 1,600 people, in 1954. After extensive efforts involving multiple rounds of Mass Drug Administration, Niue was validated by the World Health Organization (WHO) as having e4liminated LF as a public health problem in 2016. However, no surveillance has been conducted since validation to confirm infection rates have remained below WHO's elimination threshold.

Vector-borne diseases are caused by microbes transmitted to humans through vectors such as mosquitoes, ticks, flies, and other arthropods. Three vector-borne diseases, filariasis, leishmaniasis, and malaria, are significant parasitic diseases which are responsible for long-term morbidity and mortality affecting millions globally. These diseases exhibit several similarities in transmission, health impacts, and the challenges faced in their control and prevention.
