Slide 2: 

LEPTOSPIROSIS

Introduction : 

Introduction Leptospirosis is a most widespread zoonotic disease in the world caused by the pathogenic bacteria called leptospires. Human to human transmission occurs only very rarely. Generally it is transmitted by the infected urine of rodents. Case fatality may vary from 0.3 – 8 %. Severe form of leptospirosis is called Weil’s Syndrome Also included as water borne & milk borne disease

Distribution : 

Distribution Worldwide disease. Most common in tropical & subtropical areas with high rainfall. In India with frequent outbreaks in Maharashtra ,Gujarat,Karnataka , Kerala & Andaman islands especially during the monsoon.

Incidence : 

Incidence No: of cases worldwide is not known precisely. 0.1 – 1 /100,000 per year in temperate climates. 10 – 100 /100,000 per year in humid tropics. During outbreaks & in high exposure risk groups it may reach >100 per 100,000.

Leptospirosis-synonyms : 

Leptospirosis-synonyms Mud fever Japanese seven day fever Leptospiral Jaundice Spirochete Jaundice Autumn fever Elippani (mal)

History of Leptospirosis : 

History of Leptospirosis Adolf Weil described leptospirosis as a disease entity in 1886.

Leptospirosis in India : 

Leptospirosis in India 1931 – An outbreak in Andaman islands. 1960 – Serological evidence 1983 – An outbreak in cattles Now endemic in all parts of India. All cases of fever with jaundice are now screened for leptospirosis as a mandatory laboratory test.

Leptospirosis in Kerala : 

Leptospirosis in Kerala Reported in Kerala from 1997 onwards . Increasing trend of incidence is clearly seen. Case fatality rate in 2005 -10.62% 2006 -13.78% up to June 2007 -10.53% Majority of cases occurred in late Monsoon.

Leptospirosis as Epidemic- : 

Leptospirosis as Epidemic- Associated with 1. Changes in human behavior 2. Contamination of water by animal / sewage 3. Changes in animal reservoir density 4. Follow natural disasters like cyclones & floods

Slide 23: 

BLOOD TISSUES ORGANS CONVOLUTED TUBULES OF KIDNEY URINE LEPTOSPIRA Leptospires in the body

Interventions at the transmission route : 

Interventions at the transmission route Wearing protective clothings (boots,gloves ,aprons mask ,etc) . Covering skin lesions with water proof dressings.
