6. BRIEF RESUME OF INTENDED WORK:

INTRODUCTION:

Leptospirosis is severe and contagious bacterial infection. It is caused by

exposure to several types of the Leptospira bacteria, which can be found in fresh

water that has been contaminated by animal urine. The alternative names of

Leptospirosis are Weil disease, Ictehemorrhagic fever, Swine herds disease, Rice

field fever, cane-cutter fever, Swamp fever, Mud fever, heamorrhagic jaundice,

Stuttgart disease, Canicola fever and, rat fever and farmers disease in india.1

Leptospirosis is essentially animal infection by Serotypes of Leptospira

(spirochetes) and transmitted to man under certain environmental conditions. At

present, 23 sero groups and 200 serovars have been recognized from various part of

the world. It has high prevalence in warm humid tropical countries. The disease

manifestations are many and varied, ranging in severity from a mild febrile illness to

severe and sometimes fatal disease.2

The some sources of human infection are rats, dogs, cats, livestock and wild

animal. Once infected, animal excrete spirochetes in the urine for an extended period

of time. Leptospire survival outside the human host is dependent on the moisture

content, temperature and pH of the soil and water into which they are shed. The

majority of the human cases worldwide result from occupational exposure to rat

contaminated water or soil. Occupational groups with a high incidence of

Leptospirosis include agriculture workers, person who live or work in rat infested

environment, individuals involved in animal and husbandry or veterinary medicine,

and laboratory workers.3

Leptospirosis is a zoonotic spirochiteal disease of global importance. The

disease continues to have a major impact on people living at urban and rural areas in

developing countries. Leptospirosis is underreported due to lack of clinical suspicion

and barriers to diagnostic capacity. General physicians often lack familiarity with

the broad clinical presentation of leptospirosis. Most commonly, human infection

with pathogenic leptospira results in asymptomatic seroconversation and less

commonly in a symptomatic illness. When symptomatic, leptospirosis most often

manifests as an undifferentiated febrile illness. In endemic areas, factors such as lack

of sanitary conditions, mud flooring, together with rainy seasons and flooding

catastrophes contribute to periodic outbreaks.4

India is a developing country, about 72-74% of the people live in rural areas.

The main source of income is agriculture; several millions of them are either

marginal farmers or work on hired labour and struggle for bare necessities of life. It

is said that nearly 11% of the total wild animal population is in India. It is usually

observed that, animals are house under the same roof as human being. Therefore all

possibilities exist for the various diseases to be transmitted by the animals to man.5

6.1 NEED FOR STUDY:

According to WHO, the incidences ranges of leptospirosis from

approximately 0.1 1 per 1,00,000 per year in temperate climates to 10 100 per

1,00,000 in the humid tropics. During out breaks and high exposure risk groups,

disease incidence may reach over 1001,00,000. The case-fatality rates in different

parts of the world have been reported to range from

Based on National Epidemiological Surveillance of Infectious diseases

(NESID), the report on prevalence of leptospirosis showed that the estimated

sources of infection of the 93 notified cases were- Farm workers (31 cases); Leisure

activities and labour at the rivers (23 cases); contact with fresh water of other than

rivers labour(16 cases); direct and indirect contact with rodents(17 cases); unknown

(6 cases). Therefore, the sources of infection are occupational or recreational

exposure in environment contaminated with urine of carrier animals, and occupation

having a chance of direct contact with urine or blood of infected animals.7

A study was conducted on prevalence of leptospirosis in Kerala, about 37

cases were selected by using simple stratified sampling techniques. The studies

showed that people belonging to 30-45 age group were affected more(51.3%), both

males and females. There was not a single case in the 015 age groups, with 10.8%

belonging to 60 plus age group. As in the other studies, Male cases dominated- of

the total, 68% were male and 32% were female. This is despite the fact that more

than 50% of those affected are engaged in agriculture work, identified as the major

routes of transmission.8

A study was conducted on prevalence of leptospirosis among the Pyrexia

Unknown Origin(PUO) cases in a Tertiary care Hospital of Kashmir Valley, about

72 in-patients cases were enrolled as participants. All the samples are tested by

Lepto Dipstick. The study showed that of the 72 studied cases, 43 were male and 29

female, predominantly in the age group 21 40 years. Results showed that 1 of 15

urban(6.66%) and 14 of the 57 rural (24.56%) patients were positive for leptospira

8/13/2019 05_N007_16183

5/19

antibodies respectively. About 13 of the 15 patients who tested positive (86.66%)

gave a definite history of animal contact. 9

Human leptospirosis is prevalent in many states in India, sporadically or as

outbreaks, especially during rainy seasons. It affects predominantly male adults who

work in agriculture, causing severe morbidity and mortality with serious economic

repercussions to families and to society. Yet, there is no systematic leptospirosis

prevention and control programme in the country and not included under the

national health policy. Thus, Personal protection and public health control are

relevant in this disease.10

Leptospirosis is a potentially serious but treatable disease. More than half of

the total population lives in rural areas and their lives depend mainly on agriculture.

Chances of exposure to the risk factors is high due to lack of knowledge about the

illness, poor working condition and inadequate housing. Since Leptosporosis is a

public health threat and hence, it is necessary to increase awareness and knowledge

on leptospirosis among farmers in the rural areas. So, the researcher found it relevant

to evaluate the effectiveness of video assisted teaching programme on Leptospirosis

6.2 Review of Literature:

The review of literature is an organized critique of the important scholarity

literature that supports a study and a key step in the research process. The overall

purpose of review of literature in the research study is to present a strong knowledge

base for the conduct of the research project. The main goal of a literature review is

8/13/2019 05_N007_16183

6/19

to develop the foundation of a sound study, but it also is used for other scholarity,

educational and clinical practice activities. 11

A study on the prevalence of Leptospirosis among the 227 risks groups was

conducted in and around Nagpur. The test group included 55 patients of pyrexia

unknown origin(PUO), 42 veterinary workers, 38 Hepatitis patients and 25 village

farmers. The control group comprised of 27 Syphilis and 40 healthy groups. Test

was done either by IgM ELISA and by Microscopic agglutination test (MAT). Out

of 160 patients of the test group 56(35.0%) were positive for Leptospiral antibodies.

Of these, the positivity was 18(32.73%) amongst Pyrexia unknown origin (PUO), 15

(35.71%) of farm workers, 15(39.47%) of hepatitis and 8(32.0%) of farmers.

Leptospirosis antibodies was not detected in any of the control groups. Out of 56

leptospira cases, 39(69.64%) has a history of animal contacts. The result shows that

PUO patients with jaundice especially in presence of the history of animal contact

should be suspected more.12

A descriptive study was conducted to assess prevalence of leptospirosis

outbreak among the 942 clinically suspected cases of leptspirosis admitted into

Lokmanaya Tilak Municipal General Hospital, Mumbai. Serum samples were tested

by Tek Dri-Dot/Leptocheck. Among 165 positive serra by these test were sent to

IRR, Mumbai for detection of leptospira IgM antibodies by ELISA (panbio). About

87 positive sera were also sent to BJ Medical College, Pune for Microscopy

Agglutination Test(MAT) for serovar identification. Seropositivity with Leptocheck

Tek Dri-Dot/Leptocheck was 34.3 %, IgM ELISA positivity was 69.1% and MAT

positivity was 29.9%. Considering at least two of the above three serological test

8/13/2019 05_N007_16183

7/19

positive, 127 cases could be diagnosed and only 89.8% of them could be diagnosed

by ELISA and rapid test. The study therefore, concluded that alongwith rapid

serological test, IgM ELISA should be routinely done for laboratory diagnosis of

leptospirosis.13

A descriptive study on prevalence of leptospirosis in Andhra Pradesh was

done among 86 suspected cases. Of these, 49(56.97%) serum samples were found

positive for leptospirosis by DGM test and IgM antibodies. The mean age of the

positive cases were 42.7 years. All the 49 positive cases had fever (100%), Myalgia

(42.9%), stiffness of the calf muscles (55.1%) and headache (32.6%) and

conjunctival suffusion (2.04%). The studies indicated that transmission was from

contaminated stagnant water. The barefooted villagers living with livestock and

rodents were significantly associated with seropositivity.14

A descriptive study on prevalence of human leptospirosis among hospital

cases of erode, South India was performed by using isolation and serological test

such as the microscopic agglutination test(MAT) and IgM-based enzyme-linked

immunosorbent assay. Out of 29 patients, 26(89.7%) were diagnosed as having

leptospiral infection. Case fatality rate was 3.4%. The age of patients ranged

between 10-70 years and median age was 42.5 years. The study results showed that

that 93.1% of the patients were male and all patients, excepts one were agriculture

labourer. This study concluded that leptospirosis is a potential health hazard of

Agriculture Workers.15

A serological survey of Leptospira infection in Nepal by one-point

microcapsule agglutination(MCA) test was done among 200 patients(104 males and

96 females) attending out patient department. Among 200 serum samples taken-

32%(64 out of 200) of the subjects possessed antibodies to leptospira. The

Leptospira-antibody prevalence was dependent of gender and geographical

areas(P>0.05). The antibody prevalence in different age and ethnic groups ranged

from 27.5 34.0% and 28.5 40.0% respectively. The difference was not

significant (P>0.05%). The reports of the results suggested that Leptospira infections

are uniformly distributed in different age, sex, ethnics and geographical areas. 16

A study to investigate the risk factors for mortality in patients with

Leptispirosis during an epidemic outbreak in northern Kerala was done through

clinical examination, laboratory investigation and leptospira serology -Microscopic

agglutination test(MAT). Of the 468 cases suspected to have leptospirosis, serology

could be done in 360 patients. Of these, MAT was positive in 282 patients. Case

fatality rate was 6.03%.Out of 282 seropositive cases 58.9 % were men and 29%

were engaged in agriculture occupations. The result shows that majority of the

patient (62.9%) had either fissures or other wounds on the feet and no patient had

direct occupational exposure to animal.17

A leptospirosis clinical-epidemiology study was made in humans and

reservoirs. Interviews and serological analyses were made on 400 persons from an

open population; 439 probable cases of leptospirosis and 1060 animal

reservoirs(cows, pigs, dogs, rats and opossums). IgM Leptospira Dipstick and

Microscopic agglutination Test(MAT) was used to detect human antibodies to

8/13/2019 05_N007_16183

leptospiras and serovars respectively. Leptospirosis in humans was 2.2/1,00,000

inhab. In 1998, 0.7/1,00,000 in 1999 and 0.9/1,00,000 in 2000. Overall

seroprevalence was 14.2%, relatively unchanged from seroprevalences observed 20

years ago highest seroposivity was found in people over 56 years of age,

predominating males over females.Leptospirosis cases were more frequent in rural

areas. Contacts with rodents and natural water sources were significant factors

recognised. Barriers to addressing this problem have been the lack of an adequate

diagnostic test and effective control measures. China and Brazil countries have

completed the sequence of the leptospira genome. Together with new genetics tools

and proteomics, new insights have been made into the biology of leptospira and the

mechanisms used to adapt to host and external environments. Surface protein

exposed proteins and putative virulence determinants have been identified which

may serve as sub-unit vaccine candidates. Future challenges will be to translate these

advances into public health measure for developing countries. 20
