Which of the following is not a non-communicable disease?
a. herpes
b. obesity
c. skin cancer
d. high cholesterol

The correct answer is A. Herpes is not a non-communicable disease.

Explanation:

Herpes simplex is used to refer to various viral infections caused by herpes simplex viruses. Colloquially, the shortened form of herpes is usually used for a special localization on the skin.

After an initial infection (even without symptoms), the virus remains in a state of rest (latency) throughout the life of the organism, which is known as a persistent infection. This property of persistence is found in all members of the Herpesviridae family. Therapy for HSV infections cannot end this persistence, but tries to prevent the virus from multiplying after it has been reactivated from the resting state. Several antivirals are available for HSV therapy, which are highly specific.
