Usually a different and much lower-risk route than contact with broken skin or mucous membranes.

Blood and bodily-fluid exposure
Contact whose infection significance depends on the fluid, route, body site, skin integrity, amount and source context. A splash onto intact skin is not equivalent to a sharps injury or contact with eyes, mouth or broken skin.
Sexual health
In brief
Assess the fluid, route and timing—and obtain urgent advice when indicated.
Potential exposure to blood-borne viruses needs prompt, calm assessment rather than guesswork. Immediately wash a wound with soap and running water without scrubbing or sucking it, and irrigate splashes to eyes or mucous membranes with water. Seek urgent clinical advice because HIV PEP and hepatitis B prevention are time-sensitive when indicated.
Contact with an eye, mouth or nose that warrants prompt rinsing and exposure assessment.
A puncture or cut from a potentially contaminated sharp, requiring urgent clinical assessment.
Time-sensitive antiretroviral treatment used after selected significant HIV exposures, not every contact.
Immediate first aid
Encourage a sharps wound to bleed gently under running water, wash with soap and water, do not scrub or suck it, then cover it with a waterproof dressing. Rinse eyes, mouth or nose thoroughly with water.
Do not use bleach or harsh chemicals on the body. Remove contaminated clothing where appropriate and wash intact skin.
Clinical assessment
Contact urgent care, an emergency department, occupational health or a sexual-health service according to the route and local pathway. Give the time, fluid, route, injury and any known source information.
Professionals assess HIV, hepatitis B and hepatitis C separately. Vaccination history, testing and follow-up may be relevant even when PEP is not.
Risk is route-specific
Blood, semen and some other fluids can matter in particular routes; saliva, sweat, urine and other fluids are not interchangeable. Visible blood and broken skin can change assessment.
Source identity or diagnosis alone does not determine transmission. Viral suppression, fluid, route, depth, volume and timing all matter.
Reporting and support
Workplace exposures should be reported through the employer's incident and occupational-health process as well as receiving care. Preserve useful product or incident details without handling a sharp again.
An exposure can cause substantial anxiety. Use professional risk assessment and follow-up rather than repeated washing, internet estimates or blame.
Non-graphic examples
What the umbrella may include
- Washing a needlestick injury without scrubbing.
- Irrigating an eye after a blood splash.
- Seeking urgent advice about possible HIV PEP.
- Checking hepatitis B vaccination history with a clinician.
