How quickly do I need to be seen?

Same day — ideally within hours. HIV PEP is most effective the earlier it starts (the NHS cites a 72-hour outer limit) and hepatitis B measures are also time-sensitive. Do the first aid, then go straight to occupational health or A&E.

Should I squeeze or suck the wound to get the blood out?

Encourage gentle bleeding under running water, but do not scrub or suck it — that can worsen tissue damage without proven benefit.

What is my actual risk of catching a virus?

Generally low per exposure, but real. It depends on the virus, whether the source is infected and how infectious, and how deep or what type the injury was. Only testing and clinical assessment can tell you your specific risk — which is why you get seen and followed up.

I am vaccinated against hepatitis B — am I safe?

Hepatitis B vaccination is the single best protection and greatly lowers risk, but you still need assessment: the clinician checks your immunity and the exposure, and there is still no vaccine for hepatitis C or, after exposure, anything other than PEP for HIV.

Do I have to report it if it was minor?

Yes — report all exposures. Even a “minor” scratch may need PEP or hepatitis B decisions and follow-up testing, and reporting protects you for records and any work-injury coverage.

Needlestick & Sharps Injuries in Singapore: Act Fast

Written & reviewed by the BestDoctors.sg editorial team · Last updated 25 Aug 2026 · General information, not medical advice

A needlestick or sharps injury is any puncture, cut or scratch from a needle, blade, broken glass or other sharp that may be contaminated with blood or body fluid; it sits within the wider group of blood and body-fluid exposures, which also includes splashes to broken skin or the eyes, nose or mouth. It matters because such exposures can — uncommonly — transmit hepatitis B, hepatitis C or HIV. The two messages that save the most harm are simple: do the first aid, then seek urgent medical care the same day, because post-exposure treatment is time-critical.

In a medical emergency, or for severe or sudden symptoms such as breathing difficulty, chest pain, fainting or stroke signs, call 995 immediately.

Encourage the wound to bleed gently under running water and wash it — do not scrub or suck it. Then seek urgent medical assessment immediately, the same day: HIV post-exposure prophylaxis (PEP) works best the sooner it starts (the NHS cites an outer window of 72 hours), and hepatitis B measures are also time-sensitive. Go to your occupational-health service or a hospital A&E.

What it is and why it matters

Blood and body-fluid exposures can transmit bloodborne viruses — principally hepatitis B, hepatitis C and HIV. The honest framing of the risk is that for any single exposure the chance of catching a virus is generally low but real, and it depends on the virus, whether the source person is infected and how infectious they are, and the depth and type of injury: a deep jab from a hollow, blood-filled needle carries more risk than a superficial scratch. This guide gives no percentages, because only assessment can estimate an individual’s risk.

Who is at risk

Healthcare workers — nurses, doctors, phlebotomists, dentists and paramedics — are most exposed, along with laboratory and mortuary staff, and cleaners, housekeeping, laundry and waste handlers who may meet hidden sharps in bins and linen. Community, social-care and enforcement staff, and non-medical trades that break skin such as tattooists and piercers, are also at risk, and discarded needles in public places affect cleaning and grounds staff. The highest-risk moments are recapping needles, disposing of sharps, handling waste, and when a patient moves unexpectedly.

Immediate first aid

For a skin injury, encourage the wound to bleed gently by holding it under running water — do not scrub it and do not suck it — then wash thoroughly with soap or antiseptic and plenty of running water, dry it, and cover it with a waterproof dressing. For splashes to the eyes, nose or mouth, irrigate thoroughly with water or saline, rinsing the eyes open; if you wear contact lenses, rinse first, then remove and rinse again, and do not swallow. These simple steps come first, before anything else.

Act fast — the same day

After first aid, seek urgent medical assessment immediately — the same day, within hours, not tomorrow — because the key treatments are time-critical. HIV post-exposure prophylaxis (PEP), a short course of anti-HIV medicine that can reduce the chance of infection, works best the sooner it starts, with the NHS citing an outer window of 72 hours, though earlier is better and it is not always needed. Hepatitis B post-exposure measures, such as vaccine or immunoglobulin depending on your immunity and the source, are also time-sensitive. There is no vaccine or PEP for hepatitis C, so management is early testing and follow-up — and hepatitis C is now curable with modern antivirals if caught. In Singapore, go to your workplace occupational-health service or staff clinic if there is one, otherwise a hospital A&E; do not delay to find the “right” clinic.

Medical follow-up

A clinician will assess the exposure — the type of sharp, depth and fluid — and, where possible and consented, the source person’s status; take baseline blood tests; decide on HIV PEP and hepatitis B measures and review tetanus status; and arrange follow-up blood testing over the following weeks and months to confirm no transmission, with counselling and interim precautions while results are pending. Reporting the exposure promptly to your supervisor and occupational health is what makes these timely decisions possible.

Prevention and controls

Prevention follows a hierarchy: remove unnecessary sharps and use needle-free systems where possible; use safety-engineered devices with retractable or shielded needles; and never re-cap, bend or break needles by hand, keep hands away from the sharp end, and do not overfill bins. Dispose of sharps immediately into a puncture-resistant, approved sharps bin at the point of use, and seal and replace it before it is full. Gloves and eye or face protection help where splashing is possible, and hepatitis B vaccination for at-risk workers — with a check that it worked — is a key prevention offered before exposure.

Reporting and the SG context

Report every exposure to your supervisor and occupational health as soon as possible, even a minor one, since it may still need PEP or hepatitis B decisions and follow-up, and reporting protects you for records and any work-injury processes. In Singapore, employers have duties under the WSH framework administered by MOM, certain occupational diseases and incidents are reportable to MOM, and injured employees may be covered under work-injury compensation. Call 995 for any life-threatening situation such as severe bleeding or collapse.
