Full treatment for most communicable diseases can be initiated within how many hours without complications?

• A. 24 hours
• B. 48 hours
• C. 72 hours
• D. 96 hours

Answer: (C)

The main idea is timing matters: starting full treatment within about 72 hours of onset for many communicable diseases gives the best balance between effectiveness and safety. In the early phase, the infection is usually still contained and responds well to standard therapy, which helps reduce symptoms, limits spread to others, and lowers the risk of complications. If treatment is delayed beyond that window, the infection can progress, making management more difficult and increasing the chance of complications or longer recovery. There are exceptions where treatment must start even sooner due to rapid progression or life-threatening illness, but for most conditions the 72-hour window is the practical target.
