📖 Introduction
Introduction to Kala Azar (Visceral Leishmaniasis)
Kala Azar, also known as Visceral Leishmaniasis (VL) or Black Fever, is a severe parasitic disease. It is caused by the protozoan parasite Leishmania donovani, making it a significant public health concern, especially in endemic regions.
India has demonstrated substantial progress in its efforts to eliminate Kala Azar. Recent data indicates a significant reduction in case numbers, moving closer to the national elimination target.
India's Progress in Kala Azar Elimination
India reported less than one case per 10,000 population in 2023, marking a notable improvement compared to previous years. This achievement reflects dedicated public health interventions and sustained efforts.
The National Vector Borne Disease Control Programme data shows a decline in cases:
- 2023: 595 cases and four deaths
- 2022: 891 cases and three deaths
While significant progress has been made, India has not yet achieved formal elimination of Kala Azar. The country continues to work towards this crucial public health goal.
WHO Elimination Criteria and India's Targets
The World Health Organization (WHO) defines elimination for Kala Azar as having fewer than one case per 10,000 people at the sub-district (block Primary Health Centres) level.
Once this threshold is met, the elimination status must be sustained for three consecutive years to receive official WHO certification.
India's initial target year for Kala Azar elimination was 2010. This target was subsequently extended multiple times to 2015, 2017, and then 2020. The country now needs to sustain its current momentum for three years to achieve certification.
Global Context: Bangladesh's Achievement
In October 2023, Bangladesh made history by becoming the first country globally to be officially validated by the WHO for eliminating Kala Azar as a public health problem. This serves as a significant benchmark and inspiration for other endemic nations, including India.
Key Facts About Kala Azar
Understanding the fundamental characteristics of Kala Azar is crucial for both prevention and control strategies.
About Kala Azar
Kala Azar is medically known as Visceral Leishmaniasis (VL). It is caused by the protozoan parasite Leishmania donovani and is often referred to as Black Fever due to some of its characteristic symptoms.
Symptoms of Kala Azar
The disease manifests with a range of debilitating symptoms that can severely impact an individual's health.
- Irregular bouts of fever: A primary and persistent symptom.
- Weight loss: Significant and often unexplained reduction in body mass.
- Enlargement of the spleen and liver: These organs become noticeably swollen.
- Anaemia: A reduction in red blood cells, leading to fatigue and weakness.
Prevalence and Global Burden
Kala Azar remains a global health challenge, with a high concentration of cases in specific regions.
Most cases of Kala Azar occur in Brazil, East Africa, and India. Globally, an estimated 50,000 to 90,000 new cases of VL occur annually, but only 25-45% are reported to the WHO. The disease has significant outbreak and mortality potential.
Transmission of Kala Azar
The parasite responsible for Kala Azar is transmitted through a specific vector.
Leishmania parasites are spread through the bites of infected female sandflies. These sandflies feed on blood for egg production, acquiring and transmitting the parasite in the process. Over 70 animal species, including humans, can act as carriers for these parasites.
Major Risk Factors for Kala Azar
Several socio-economic and environmental factors contribute to the spread and severity of Kala Azar.
- Poverty: Limited access to healthcare and resources.
- Poor housing and sanitation: Creates favourable breeding grounds for sandflies.
- Diets lacking essential nutrients: Weakens the immune system, making individuals more susceptible.
