Defining Communicable Diseases

Question 2 • Health and Wellness Education

Which statement BEST describes a treatment for a contagious illness?

Answer

Bacteria, molds, or synthetic substances are used to create antibiotics, which are the most successful treatment for bacterial illnesses.

Viral infections are best treated with antibiotics and vaccines, which are made from the pathogen that they are meant to treat.

Treatment for fungal infections is made from different forms of molds, which can be taken orally or topically.

Vaccines are made from molds and bacteria and are used to treat and prevent different viral infections.

Explanation

Antibiotics are made from substances produced by some bacteria and molds, or are synthesized, and they are used to treat bacterial illnesses. They do not treat viral infections, so choices B and D incorrectly describe antibiotics or vaccines as treatments for viruses. Choice C is too broad: antifungal medicines are not all made from molds.
