The human body is immune to which of the following diseases?

  1. Small pox

  2. Diabetes

  3. Tuberculosis

  4. Jaundice
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Smallpox is an ancient disease caused by the variola virus. Early symptoms include high fever and fatigue. The virus then produces a characteristic rash, particularly on the face, arms and legs. The resulting spots become filled with clear fluid and later, pus, and then form a crust, which eventually dries up and falls off. Smallpox was fatal in up to 30% of cases. There is a vaccine against smallpox that was a key tool in the eradication of the disease. This vaccine does not contain the variola virus which causes smallpox, but a closely related virus called vaccinia. When this vaccine is given to humans, it protects them against smallpox. 
So the correct option is 'small pox'.
