“…A strong fall in the average load of microfilaria to average load of infective stages in those vectors shows a natural bearing in control of filarial transmission in both urban and rural area, which was also reported in some other studies [9,10,22]. However, average load of parasites per vectors was higher in urban area than in rural area (p>0.05).…”

Information about filarial vector was available from different parts of West Bengal in India [5][6][7][8][9][10]. Nevertheless, information on vector related indices from many areas is scanty. Therefore, the present study has been carried out to collect information on different aspects related to the vector such as species composition of mosquitoes, ManHour Density (MHD) of the vector, percent of shelters with infected and infective vector, vector infection and infectivity rates, number of vectors containing different stages of parasites as well as total count of the parasites, age composition of the vector etc. from an urban and a rural area of West Bengal, India, with a comparative view. Materials and MethodsFor the present study, 8 localities in Kolkata (Dum Dum, Park Circus, Topsia, Jadavpur, Kathgola, Ballyganj, South Sealdah and Nawpara) were selected as urban study area and another 8 localities in Tenya gram-panchayet of Murshidabad district (Baidyapur, Powa, Ghosh para, Subhendupur, Pallyshree, Sahapur, Kulu pukur and Gouri nagar) as rural study area. The urban study area is located at the bank of Hooghly river in the Ganges delta, at around 22.62°N and 88.42°E, monotonously plain, with elevation above sea level being about 17 feet. The rural study area is located at the bank of Bhagirathi (upper part of Hooghly) river, at around 23.84°N and 88.18°E, almost plain, with elevation above sea level being about 62 feet.Indoor-resting mosquitoes were captured for 12 minutes from 5 human habitations fixed in each locality of each area, once in a month. AbstractBackground: Despite of all types of efforts, mosquito born disease like lymphatic filariasis seems to cause new disease burden in many countries. Proper information about the vector of these diseases is necessary to stop the transmission, but sometime information on vector is scanty from many areas. Present study is designed to collect comparative information about the filarial vector from rural and urban areas of West Bengal in India.Methods: Regular collection of indoor-resting mosquitoes was done from the human habitations of Kolkata (urban area) and Tenya of Murshidabad district (rural area) for 2 years. Collected mosquitoes were identified and examined for different parameters following standard methods recommended by World Health Organization and pioneer workers of the field. Conclusion:Different indices related to the vector mosquito were much higher in urban area of Kolkata than rural area of Tenya in Murshidabad, which indicates that, situation is more favourable in urban study areas for transmission of lymphatic filariasis than the rural one, though the situation in the rural area cannot be neglected. Available data will help to formulate an effective management strategy in those areas. et al., Trop Med Surg 2013, 1:1 DOI: 10.4172/2329 Results: In both the areas Wuchereria bancrofti was identified as the causative parasite of filariasis and Culex quinquefasciatus as the vector. In the urban area, overall man hour density, infection rate, infec...

“…However, during periods of increased heat and humidity, the number of vectors decreases, although there is no synchrony between the infecting larvae and the number of vectors, and the transmission risk decreases. One of the factors that may have contributed to the nonproliferation of the disease is the lack of synchronization between the number of vectors and the environmental conditions for the development of the agent that causes the disease 17 . Several vector types are involved in filariasis transmission, including mosquitoes of the genera Culex, Anopheles, Aedes and Mansonia 18 .…”

The study was conducted in three cities of the western Brazilian Amazon region -Porto Velho and Guajará-Mirim (State of Rondônia) and Humaitá (State of Amazonas). Methods: For human infection evaluation thick blood smear stained with Giemsa was used to analyze samples collected from 10pm to 1am. Polymerase chain reaction (PCR) was used to examine mosquito vectors for the presence of Wuchereria bancrofti DNA. Humans were randomly sampled from night schools students and from inhabitants in neighborhoods lacking sanitation. Mosquitoes were collected from residences only. Results: A total 2,709 night students enrolled in the Program for Education of Young Adults (EJA), and 935 people registered in the residences near the schools were examined, being 641 from Porto Velho, 214 from Guajará-Mirim and 80 from Humaitá. No individual examined was positive for the presence of microfilariae in the blood stream. A total of 7,860 female Culex quinquefasciatus specimens examined were negative by PCR. Conclusions: This survey including human and mosquito examinations indicates that the western Amazon region of Brazil is not a focus of Bancroftian filariasis infection or transmission. Therefore, there is no need to be included in the Brazilian lymphatic filariasis control program.

Filariasis has been a public health problem in Indonesia for a long time and WHO has established this disease as a neglected disease which is a public health problem in the world, therefore a global filariasis elimination program that must be achieved in 2020. This article compiles some literature for writing references related to the development of global filariasis elimination and the progress of filariasis elimination in Indonesia particularly. Filariasis elimination program in Indonesia has been running at least 26 districts that have stopped implementing mass drug administration (MDA) from 239 endemic filariasisdistricts. The remaining districts are expected to have implemented MDAstart from 2015 so that the year 2020 is completed and verified also given predicates of filariasis elimination according to global target of filariasis elimination. Management-based and community-based research is important to determine the best model of elimination. There are still many challenges in increasing coverage, so that continuing education efforts on filariasis and the importance of treatment will motivate communities to play an active role in achieving maximum coverage targets, and national filariasis elimination targets can be achieved by 2020.
