How long can HBV survive outside the body?

• A. 1 Day.
• B. 3 Days.
• C. 7 Days.
• D. 14 Days.

Answer: (C)

HBV can remain viable outside the body for up to seven days on surfaces or in dried blood. That level of environmental resilience means a surface or instrument touched days later could still pose an infection risk if it wasn’t properly cleaned and disinfected. In tattoo and body piercing settings, this drives strict infection-control habits: use barriers to prevent contamination, treat all surfaces as potentially infectious, clean and disinfect with products proven to inactivate HBV, and sterilize reusable instruments or use single-use disposables. Seven days is the commonly cited timeframe for HBV’s outside-the-body survival, reflecting why diligent precautions are essential to prevent transmission.
