What CDC says about tattoos and piercings

CDC states that there are no known cases of anyone getting HIV from tattoos or body piercings. It also notes that it is possible to get HIV this way if the equipment or ink contains blood from someone with HIV.

Both parts matter. The first tells you the real-world risk has been too small to record. The second tells you exactly where the risk would come from: blood left on a needle, in ink or on tools that were used on someone else and not replaced or sterilized.

Why the risk is so low

For HIV to pass on, blood from someone with HIV has to get into your body. A well-run studio uses new needles for each client, pours a fresh portion of ink for each person, and sterilizes any reusable tools. That breaks the chain.

Even where hygiene is poor, three things would need to line up: a previous client with HIV, their blood remaining on the equipment, and that equipment being used on you.

Where tattoos and piercings do carry infection risk

HIV isn’t the main concern. WHO lists tattooing and piercing among the ways hepatitis B spreads, along with needlestick injuries and exposure to infected blood. Hepatitis B is a good reason to be careful about where you go, and a good reason to ask your doctor whether you’re vaccinated.

The higher-risk settings are the ones without proper equipment:

  • tattoos done at home, at parties or by unlicensed artists
  • shared or homemade needles, or ink reused between people

How to choose a safe studio

  • Use a licensed studio or piercer.
  • Watch them open new, sealed needles in front of you.
  • Check that ink is poured into a fresh cap for you and thrown away afterwards.
  • Look for gloves, a clean work area and a sterilizer for reusable tools.

If anything looks reused, it’s fine to walk out.

Shared razors and toothbrushes

CDC’s guidance on how HIV spreads doesn’t list sharing razors or toothbrushes. HIV doesn’t survive long outside the body, for example on surfaces. To cause an infection, blood carrying the virus would have to get into an open wound or a mucous membrane. Brushing your teeth or shaving with someone else’s razor isn’t a recognized way to get HIV.

They can still carry small traces of blood, so keep your own razor and toothbrush and don’t share them. That’s good hygiene for other infections, not a sign that you’re at risk of HIV.

What actually does carry risk

For comparison, shared injecting equipment is a real route for HIV, because blood can stay inside a used syringe. Live HIV has been recovered from syringes kept at room temperature for more than four weeks (Abdala 1999). With someone who has HIV and isn’t on treatment, CDC estimates the risk of one shared injection at 0.63% (about 1 in 160). Using homemade or shared needles for tattoos or piercings comes closer to this than anything that happens in a licensed studio.

What to do now

  • Tattoo or piercing at a licensed studio? There’s nothing you need to do for HIV.
  • Unlicensed setting, shared needles or reused ink? The HIV risk is still low, but it’s sensible to ask a clinic about testing for HIV and hepatitis B after the window period. The HIV testing guide explains which test to take and when.
  • A needle used on someone else broke your skin in the last 72 hours? Treat it as a needlestick and ask about PEP (post-exposure prophylaxis) today. How to get PEP
  • Shared a razor or toothbrush? You don’t need PEP or an HIV test because of it.
