Question

The disease caused due to worms is
A) Tetanus
B) Rabies
C) Sleeping sickness
D) Filariasis

Answer 1

Disease is a disorder of structure or function in the body of a person that is caused by genetic inheritance or gained from the atmosphere. Climatic factors, unhygienic conditions and a variety of daily activities including eating habits contribute to a spectrum of infections caused due to worms. These diseases have become the biggest concern nowadays.

Complete answer:
Let us infer the options given above:
A) Tetanus- It is a serious disease of the nervous system that is caused due to toxin-producing bacterium called Clostridium tetani. It is commonly called lockjaw that is mainly a life-threatening problem. When the bacteria invade the body they produce a poison that causes painful contraction of the muscles. Presently there is no cure for this problem till now.

B) Rabies- A deadly viral disease that is spread throughout the body and majorly inflates the brain of a person through the bite of a dog. Early symptoms include fever and itching at the site of the exposure. The time period between contracting the disease and the start of the symptoms is between one to three months, it depends on the distance that the virus has to travel along peripheral nerves to reach the central nervous system.

C) Sleeping sickness- It is an infection that is caused by tiny parasites carried by certain flies, resulting in swelling of the brain. It is caused due to Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense. It has flourished in the rural part of sub- Saharan Africa and is carried away by Tsetse flies of the genus Glossina. The parasites live and multiply extracellularly in the blood and tissue fluids of their human host.

D) Filariasis - Wuchereria, the filarial worms cause a slowly developing chronic inflammation of the organs in which they live for many years, usually, the lymphatic vessels of the lower limbs and the disease are called elephantiasis or filariasis. The genital organs are also often affected, resulting in gross deformities.

Thus the correct answer is option ‘D’.

Note: The advancements made in biological science have armed us to effectively deal with many infectious diseases. The use of vaccines and immunization programmers have enabled us to completely eradicate a deadly disease like smallpox. A large number of other infectious diseases like polio,diphtheria,pneumonia and tetanus have been controlled to a large extent by the use of vaccines.
