Project Description

RATIONALE

Tribal population constitutes an important fraction of Nepal’s population. Their overall status directly or indirectly contributes to country’s state of economy, health, manpower resources and productivity.

The tribal population of Nepal is far away from the mainstream population. They are still found to be practicing primitive life style and are unaware of basic modern amenities of life. Various factors like poverty, illiteracy, lack of awareness, malnutrition etc further increases their state of miseries and hardships. This deprived and depressed part of population contribute an important role of carrier and reservoir of some endemic diseases as their socio-economic and socio behavioral practices favour a good member of pathogenic parasites to survive.

The present study has been selected among Chepang (Praja), a tribal community to obtain their health status in relation to their socio-economic, socio-cultural and behavioral practices. The aim of the present study is to highlight the endemic parasites in Chepang community. These parasites unknowingly influence on the health and have a direct bearing on the incidence, cause and outcome of a variety of parasitic diseases as well as many other health problems besetting the world today. Parasitic diseases probably retard or reduce the socio-economic development to a greater extent and declare them to be the public enemy number one.

Parasites have an important effect on the provision health care to all strata of society. Poverty, malnutrition, poor sanitation, age factors, lack of education, cultural and behavioural factors all predispose to ill health. Parasite infection contributes directly to malnutrition and malnutrition in turn reduces the resistivity or immunity of an individual to parasitic diseases. Zoonoses with reservoir of infection in domesticated animals impose particularly a serious burden of ill health on vast number of people who live in rural areas.

There exist very complex relationship between parasitic diseases and economic development. According to Oliver (1974) it is not easy to access the socio-economic impact of parasitic diseases but the adverse effect of parasitic disease in economic development is widely accepted.

Lymphatic filariasis (LF) also known as elephantiasis is a parasitic disease caused by filarial nematode, Wuchereria bancrofti, the infection of which causes the inflammation of lymphatic system resulting hydrocele of scortum, breast enlargement, lymphoedema of limbs, enlargement of penis, swollen clitoris and vulva. Other complications may include acute fever, chyluria and chronic pulmonary fibrosis.

Baseline survey of LF has been conducted in some of the districts of Nepal. Some districts have shown high prevalence of Mf of W. bancrofti and endemicity rate of LF.

Malaria in its various forms has been the cause of mortality in Nepal through out the ages. The endemic malarial parasites have shown periodic malaria outbreaks. The Chepangs live near the forests which are the favourable sites for the malaria vectors.

Intestinal parasitosis is highly prevalent in rural communities of Nepal (Sherchand et al., 1997) and constitutes an important cause of morbidity and mortality among Nepalese. In certain rural areas, prevalence has been found to be over 90% (Rai et al., 2000). Thus the public health importance of intestinal parasitosis continues because of its high prevalence, virtually global distribution and effects on both nutritional and immune status of individuals (WHO, 1987).

Likewise injury from venoms of the arthropods is a common hazard in temperate and tropical regions. From order Anoplura, three varieties of wingless insects commonly attack man, although others infest the lower animals and may become temporarily deposited upon human hosts. They are Pediculus humanus var. capitis (head louse), P.humanus var. corporis (body louse) and Pthirus pubis (pubic or crab louse). Mites cause scabies.

Each variety of lice has a predilection for certain parts of the body and rarely migrates to other regions. They attach themselves to the skin and live upon the blood that they suck. In piercing the skin the parasites exude an antigenic salivary secretion. This, together with the mechanical puncture, produces pruritic dermatitis. In addition, the louse may be a carrier of disease and through its bite or excretions may transmit as infectious disease – epidemic typhus, relapsing fever, or trench fever.

Pediculosis capitis: There is usually intense pruritus of the scalp, and the affected hairs become lusterless and dry. Because of the itching, secondary complications with impetigo and furunculosis are common. Owing to secondary infection, the cervical lymph glands may become enlarged.

Pediculosis corporis: This is also known as pediculosis vestimenti or vagabond’s disease. These live in the seams of clothing, especially wherever there is pressure, and therefore warmth, as beneath the belt or the collar, or in bedding. The parasite is rarely discovered on the skin, but obtains its nourishment from it by descending to the skin and piercing it with its teeth. The disease causes generalized itching, which may be accompanied by erythematous macules or urticarial wheals due to the punctures, or by excoriated papules, parallel linear scratch marks, and a pigmented thickening of the skin from continued rubbing. Secondary furunculosis is common.

Pediculosis pubis: This disease is contracted chiefly by adults as the result of sexual intercourse. The crab louse, usually limits its incursions to the genital region and hypogastrium or, rarely, the axillae or eyelashes. The symptoms vary from slight discomfort to intolerable itching.

Scabies due to itch mites Sarcoptes scabiei is characterized by pruritic popular lesions and also burrows, which house the female and the young ones. Scabies is usually contracted by close contact such as nursing an infested patient, overcrowding, close living quarters as occurs in institutionalized patients, or sleeping together, and only infrequently by the common use of contaminated towels, bed linen, and clothing. The diagnosis is made however, from the distribution of the itching and the lesions present. When the disease has been present for a long time eczematization, lichenification, impetigo, and furunculosis may be present.

OBJECTIVES

General Objective

To study the epidemiology of endemic parasites among Chepangs at Taklung VDC of Gorkha aiming at elevating health status of the Chepangs.

Specific Objectives

  • To determine the prevalence of intestinal parasites among Chepang population.
  • To find out the status of filariasis among the study population.
  • To study the status of ectoparasites like head louse, body louse etc. among the Chepang people.
  • Prevalence of Malaria survey.
  • To bring awareness about different aspects of parasites among the Chepang people.

MATERIALS AND METHODS

Study Site

The study will be carried out in the Chepang community of Taklung VDC at Gorkha district. Gorkha district is located between 488 to 7162 meter altitude and 27015' to 28045' latitude North and 84071' to 840 98' longitude east. It's boarder are Chitwan district in the South, Lamjung and Tanahun in South West, Dhading in East, and Manang in the North. Gorkha district is surrounded by Budigandaki in East, West and South while by Marsyangdi river (CBS, 2001).

Gorkha district is divided into sixty eight VDCs and one municipality. Among sixty eight VDCs, Chepang communities are present in only four VDCs. This district is one of the Hilly and some what rectangular extending from North to South with an area of 3,610 square kilometers. The average temperature of the district is 250C (Red Cross Profile, 2061).

In Nepal the total population of Chepang is 52,237. In Gorkha district, the population of Chepang is only 2742 in which males are 1341 (48.91%) and females are 1401 (51.09%).

In Nepal, more than 75 ethnic groups are present, speaking over 35 languages (Bista, 1985). Taklung VDC has 14 ethnic groups. Chepangs are one of them. There are people of seven different religions in this VDC. The famous hill lake Danda is at about 2200 meter height. Danda is located at about 1800 meter height while Dhodeni is at about 488 meter height. This VDC is attached to the Kuringhat in the Southern side of Chitwan district and about 10 Km. from Mugling (CBS, 2001).

There are 68 Village Development Committees (VDC) in Gorkha district. The selected area for study is ward no. 1 and 3 of Taklung VDC. Taklung VDC is attached to famous Manakamana. The total population of Taklung VDC is 5413 in which males are 2545 (47.02%) and females are 2868 (52.98%), sheltering in 964 households. Among total population 360 are Chepang community sheltering in 63 households (CBS, 2001). But at present the expected number of Chepang is about 500.

Chepang Community

In past time, Chepang community used to migrate from jungle to jungle and had shelter in caves. They still utilize tubers, insect, roots, fruits, wild shoots as good source of food. Hence, Chepang are previously caucasoid people of lean frame. They were nomadic tribes but nowadays they have settled community near jungle.

Settlements

Chepang inhabits near the jungle and their houses are small and low in height. They visit from place to place and still utilize cave for hunting and storage purposes. Houses are at 5 to 10 m distance at a single place. They have bad sanitary condition. They live with clustered dwelling, poultry, muddle dwelling with cracks and pig shelter. Open air defecation practice serves as a means of transmission of zoonotic diseases. Every household keeps pigs, hen, goats for personal use and also to sacrifice for God and Goddess in Baishak Purnima and other cultural activities.

Food and Water

Chepang feed on grains such as Kodo, corn etc. as food. They are omnivorous in habit with meat of different animals such as buffalo, pig, chicken, fish, goat, ox, cow etc. in their food. They lack proper knowledge of transmission of diseases. They eat inadequate cooked meat with drinks and raksi (locally prepared alcohol). They eat tarul, sakharkhanda, vacure, gittha and also wild fruits, such as daicamblo, katuse, chiuri, wild mango, valayo etc. They also feed on various types of insects, and larvae of wasp, aringle, bee, bachhim etc. as well as aquatic animals such as crabs, prawn, fish, molluscs etc.

The major source of water is Kholsa for drinking, washing and bathing etc. Some Chepang community utilizes tap and well water. Kholsa is a kind of small but very deep land, usually in the hilly region, where people get many small sources of water. It is very wet and humid, usually made by a small stream flowing down.

Study Design

Sentinel surveillance study design will be carried out and the entire study will be divided into five parts:

  1. Questionnaire survey for socio-economic and health condition
  2. Stool sample collection, examination and identification for intestinal parasites.
  3. Blood sample collection, examination and identification for filarial parasite.
  4. Blood examination of fever cases of suspected malaria.
  5. Awareness programme about parasites and medicine distribution to the infected individuals.

Sample Size

The total expected Chepang population i.e. 500 of ward no. 1 and 3 of Taklung VDC will be the target group.

Diagnostic Tools

  • Questionnaire:

    A set of structured questionnaire will be prepared and administered in order to determine the impact of parasitic infections regarding their socio-economic condition.
     
  • Sample Collection:

    Stool samples will be collected and preserved in a suitable preservative for the diagnosis of intestinal parasites.

    Night blood samples between 11 pm to 2 am will be collected and thick three smears on a slide will be prepared for the Lymphatic Filariasis.

    Ectoparasites and diseases due to ectoparasites will be identified clinically.

    Blood samples of the suspected malaria case having fever will be collected for blood smear (thick and thin) preparation on a slide or 5ul blood will be collected for RDT use.
     
  • Lab Diagnosis

    The collected samples will be examined and diagnosed in the laboratory by using suitable methodology.
     
  • Drug Administration

    After the lab diagnosis drug will be provided or will be advised to the infected respondents.
