History of Kala-azar disease

This disease first appeared in Assam in 1870, which spread rapidly along the Brahmaputra and Gangetic plains to Bengal and Bihar. Lakhs of people lost their lives due to this disease. Dr. French, civil surgeon of Burdwan district of West Bengal, first noticed its symptoms in some people in 1854-1875.

Then this disease was named Burdwan fever. In the year 1882, the then Civil Medical Officer Clark McNaught also observed such symptoms in Tura, Assam. The people of Assam named this disease Kala-azar. In 1903, William Leishman and Charles Donovan discovered the pathogen by performing autopsies on two soldiers from Calcutta and Madras. Sir Ronald Ross named it Leishmania.

Why is Kala-azar dangerous?

WHO has considered this disease dangerous. The biggest reason for this disease is its not being identified at the right time. Most people ignore it as normal fever and do not get treated. Wherever such cases occur, the government sprays pesticides to kill sandflies, but in many areas people refuse to do so, as they feel that it will harm them. Not being aware about this disease makes it dangerous.
