Which of the following diseases can be transmitted from one person to another through tattooing? 1. Chikungunya 2. Hepatitis B 3. HIV-AIDS Select the correct answer using the codes given below.

Tattooing is a percutaneous procedure: the needle breaks the skin and can carry blood from the previous client. Any blood-borne pathogen that survives on contaminated needles, ink or equipment can pass to the next person. That makes statements 2 and 3 possible and statement 1 not possible, so the answer is B.

• Statement 1 (Chikungunya): Not a tattoo-transmitted disease. It is a viral illness spread by the bite of infected Aedes mosquitoes, not by blood contact.
• Statement 2 (Hepatitis B): Possible. HBV is present in blood in high concentration and survives outside the body for days, so shared or unsterilised needles are a known route.
• Statement 3 (HIV-AIDS): Possible. HIV spreads through infected blood, and unsterilised tattoo needles are a documented risk.

Core concept: parenteral transmission of blood-borne infections, which links to the communicable disease and infection-control parts of the syllabus. In Mains, this supports a discussion on unregulated tattoo and piercing outlets and why licensing and sterilisation matter.

Trap: Candidates see Chikungunya in the list and assume any outbreak disease could have a contact route, or they rule out HIV because transmission through tattooing is less common. The question asks about possibility, not frequency.
