Question

The disease that may cause sterility due to infection spreading to sex organs is:
A. Measles
B. Syphilis
C. Gonorrhoea
D. Mumps

Answer 1

Hint: When infection by Mumps virus becomes complicated, it spreads to the testis and ovary. The signs and symptoms include fever, muscle pain, headache, poor appetite, and fatigue. These are initial symptoms that are followed by painful swelling of one or both parotid salivary glands.

Complete answer: Mumps is a viral disease.
1. It is caused by the mumps virus and is a very contagious disease.
2. It spreads rapidly among people coming in close contact.
3. Further complications may include pancreatitis, meningitis, cardiac inflammation, permanent deafness, and testicular inflammation.
4. Testicular inflammation may result in infertility.

Measles is also a contagious illness.
1. It is caused by a virus from the paramyxovirus family.
2. These replicate in the nose and throat of an infected child or adult.
3. When someone infected with measles coughs, sneezes, or talks, the droplets spread in the air, and other people may inhale them and get infected.
4. The causing agent is the Rubeola virus.
5. The symptoms include fever, respiratory issues, and rashes.

Additional information: Both gonorrhoea and syphilis are sexually transmitted diseases (STDs). Gonorrhea is caused by the bacterium Neisseria gonorrhoeae; the symptoms include a persistent sore throat.
Syphilis is caused by Treponema pallidum; its symptoms start as painless sore- typically on the genitals, rectum, or mouth.
Syphilis spreads from person to person via skin or mucous membrane contact with these sores. These do not cause sterility though.

So, the correct answer is D. Mumps.

Note: In women ovarian swelling may develop due to complicacy of mumps disease, but this does not increase the risk of infertility.
