Question

Which is the most fast-spreading disease?
A. Malaria
B. Plague
C. Poliomyelitis
D. Leprosy

Answer 1

Usually communicable diseases spread very fast. Communicable diseases are also known as contagious or infectious diseases. These diseases can spread through infection that passes through the air, water, food, touch, or by other means of contact.

Complete answer:
a) Plague – It is also known as the black death or bubonic plague. It is caused by the bacteria Yersinia pestis. Rodents are the carriers of this disease. It spreads from rat to rat and man via the rat flea. Moreover, if an infected person coughs or sneezes, then a healthy person can also be infected with this disease, and hence, it spreads very fast and takes the form of a pandemic.
b) Malaria – Malaria is caused by the protozoan Plasmodium. It spreads in humans through the bite of the female Anopheles mosquito. The breeding ground of the female Anopheles is closed places having stagnant water.
c) Poliomyelitis – Polio is also known as infantile paralysis. It spreads mainly through intestinal discharges. It can also spread through contaminated food and water. It is a viral disease that is caused by Poliovirus. Polio can be prevented with the help of its vaccine.
d) Leprosy – It is also known as Hansen’s disease. It is caused by the bacteria Mycobacterium leprae. This disease was discovered by Hansen. This disease can spread through nasal discharge and sneezing, coughing, speaking, and broken skin lesions.
Hence, the correct answer is option B.

Note: Plague is characterized by high fever and the formation of a lump known as the bubo in the groin or the armpit region. Red patches appear on the skin. These patches gradually turn black and they ultimately cause death.
