Question

Sandfly is the vector of Kala-azar.

• A. True
• B. False

Answer 1

The correct option is A True

1. Sandfly: Sandflies are psychodid Diptera belonging to the Phlebotominae subfamily. Their life-cycle consists of two biological stages: the free-flying adult and the developmental stages, which include the egg, four larval instars, and pupa, and take place in damp, organic-rich soil.
2. Kala-azar: Infection with leishmania parasites causes this sickness.
   Sandfly bites propagate visceral leishmaniasis. Internal organs, mainly the spleen, liver, and bone marrow, are affected by this kind of leishmaniasis.
   Some persons have no signs or symptoms. Fever, weight loss, and spleen or liver swelling may be symptoms for others.
   The parasites can be killed with medication. Severe instances are usually lethal if left untreated.

Final answer: The given statement is True.
