Man is definite host and mosquito is intermediate host of bancroftian and brugian filariasis. The adult filarial worm lived in lymphatic vessels and microfilaria lived in peripheral blood and infect mosquito at the time of when they come to feed . Contu…..: Contu ….. This infection caused lymphadenitis, elephantiatis with ivolment of body parts like –genital area,leg, arm. This also caused tropical wsinophillia due to hypersensitivity. Severe deformities and disability. Disease is ENDEMIC. Found in 250 districs in 20 state. 600 million people have risk of infection(according to recent estimation in South East Asia). Burden of disease: Burden of disease Lymphatic filarisis is prevalent in 18 states and UT’s. B.Filarisis is widly distrubuted,Brugian filarisis is restricted to 6 states-UP ,Bihar Orissa, Tamilnadu,Kerala,Andhra Pradesh and Gujarat. According to Survey and Control Unit; 420million are exposed to risk of infection, 19million manifested,25million have filarial parasites in their blood. Economic Loss: Economic Loss About 1.2 million people dies due to filariasis every year.That leading to an economic loss of Rs-3500 caror. Indices of filaria: Indices of filaria Parasitological indices a. Microfilaria rate- % of person showing Mf in their peripheral blood in sample population. b. Filaria endemisity rate- % of person showing Mf in blood and disease manifested or both. c. Michrofilarial density - number of Mf per unit volume of blood in samples from indivisual persons. d. Avarage infestation rate - avarage number of microfilaria. Cont…..: Cont….. 2.Entomological indices- a. Vector density per 10 man- hours catch. b. % of mosquito positive all stage of development. c. %of mosquito positive for infective larve. d. Type of breeding place. Programme: Programme The National Filaria Control Programme was launched in 1955. The activities are mainly confined to urban area. However, the programme has been extended to rural area since 1994. Objective: Objective Reduction of problem in un-surveyed area. Control in urban area through recurrent anti-larval and anti-parasitic measures. engineering Control Strategy- a. Vector control through anti-larval spray/ application at weekly intervals with appropriate larvicides. b. Biological control through larvivorous fishes. PowerPoint Presentation: c. Environmental engineering through sources reduction and water management. d. Anti-parasitic measures through diagnosis and treatment of Mf carriers and cases. e. IEC to generate the community awareness. National Health Policy: National Health Policy Indian National Health Policy (2002) envisages elimination of lymphatic filariasis by 2015. Definition: “Lymphatic filariasis ceases to be public health problem, when the number of Mf carriers is less than 1% and the children born after initiation of elimination of lymphatic filariasis are circulating antigen”. Cont…..: Cont….. The strategy of filariasis elimination is through- 1. Annual Mass Drug Administration(MDA) of singale dose of antifilarial drug for 5 yrs or more to eligible population(expect pregnant women, child below 2yrs, seriously ill person) 2. Home based management of lymphodema filariasis cases and up scaling of hydrocele operation Control Measures: Control Measures Chemotherapy: Chemotherapy Diethylcarbamazin- Most generaly accepted method 1. Bancroftian filariasis- Dose- 6mg/kg body wt/day - orally (this amount to be total of 72mg of DEC/ kg body wt.) 2 . Brugian filariasis- Dose- 3-6mg/kg body wt./day(total dose 36- 72/kg body wt.) : 1.Mass Therapy- DEC given everyone irrespective of whether they have Mf or sings of disease. 2. Selective treatment- DEC given only to Mf positive patient 3. DEC medicated salt Very low dose given over a long period of time. e.g. 1-4mg/kg body wt.(6-9months). Filarial control in community- 4. Ivermectin Vector Control: Vector Control 1.Antilarval Measure a. Removal of pista plants b.Chemical Control 2.Anti-adult Measure 3. Personal Protection 4.Environmental sanitation National Filaria Control Programme: National Filaria Control Programme Programme is operative in filarial endemic area to cover 48 million population through 206 unit, 199 filarial clinics and 27 filarial survey unit carry out delimitation surveys. Strategy includes Recurrent weekly antilarval operations biological control of vector through lavorous fish. Cont..: Cont.. Sources reduction through environmental and water management. Diagnosis and treatment of Microfilaria carriers and management of cases. IEC for community awareness. With the view to make effort towards elimination of lymphatic filariasis and consequent to recommendation of revised Filarial Control Strategy(2004) of single dose mass drug administration(DEC). Cont…: Cont… In 1997, drug administration has been initiated in identified district in 7 states, these includes East Godavari and Shrikakulum(AP), Durbhanga and Siwan(Bihar), Khurda and Puri(Orissa),South Arcot-cuddalore and North Arcot-villupurum(Tamil Nadu),Gorakhpur and Varanasi(UP),Prula(West Bengal). Cont… : Cont… A poilot project on co-administration of DEC and Albendazole as annual mass drug administration strategy has been taken in collaboration with NAMP and NICP in identified area of Kerala, Orissa and Tamil Nadu. A national test force of lymphatic filariasis elimination has been constituted under the chairmanship of Director General of Health Services Government of India. Cont…: Cont… It is now recognized that the horizontal approach making the use of Primary Health Centre system is considered essential. The village health will have to be trained and involved in active antilarval and anti-filarial activity with community participation. cont…: cont… There are 4 rural research training centre on each in AP, Maharashtra, MP, and UP. There are 3 regional research training centre situated at Calicut,Rajahamandm(AP)and Varanasi(UP). Another National Institute of communicable disease Delhi at the state level 12 headquarter bureaus are functioning.
