What are the causative agents of the following diseases?
(a) Kala-azar
(b) Acne
(c) Sleeping sickness

Why is it more difficult to make antiviral medicines than antibacterial medicines?

Kindly answer both.

Dear Student,

1. a) Kala Azar also known as Leishmaniasis is caused by Leishmania donovani.

b)Acne: Staphylococci sp.
c) Sleeping sickness known as Trypanosomiasis is caused by protozoa Trypanosoma brucei.

2. Antiviral drugs are difficult to make as viruses are non active when they are outside the cell and they replicate inside the host cell so it is very difficult to target those cells of the host which are infected by the virus.
