Which of the following is a characteristic of viruses in the salon safety context?

• A. They are easily killed by antibiotics
• B. They are spread primarily through clean towels
• C. They require host cells to reproduce
• D. They cannot cause respiratory infections

Answer: (C)

Viruses cannot replicate on their own; they must hijack living host cells to produce more copies. That essential trait is what makes this option the best answer: viruses depend on a host cell to reproduce, which is the defining difference from many other microbes. In salon safety, this matters because antibiotics don’t kill viruses—their role is focused on preventing transmission and using disinfectants that inactivate viruses on surfaces and tools. The statement that viruses are easily killed by antibiotics is inaccurate for that reason. Saying they spread primarily through clean towels isn’t correct either, since viruses can spread via multiple routes, including respiratory droplets, contaminated instruments, and direct contact. And the idea that viruses cannot cause respiratory infections is false, as many viruses do cause respiratory illnesses.
