Explanation:

• Kala-azar or visceral leishmaniasis (VL) is a tropical disease characterised by irregular fever, weight loss, anaemia and swelling of the spleen and liver. It is caused by a protozoan Leishmania parasite and is transmitted to humans by the bite of infected female sandflies.
• According to the World Health Organisation (WHO) India accounts for about two-thirds of the total 7 to 10 lakh new global cases annually, and the disease is endemic to Bihar, Jharkhand, Uttar Pradesh and West Bengal. An initiative was launched by WHO to eliminate VL as a public health problem from the South East Asia region by 2020, which has since been extended to 2023.

Hence all statements are correct.
