Hepatitis C in Malaysia: Symptoms, Testing & Cure
Hepatitis C is a blood-borne viral infection (sometimes grouped under STDs because of sexual transmission risk in HIV-positive MSM). Once untreatable, it is now curable in over 95% of patients with a short oral course of direct-acting antiviral therapy. Most chronic HCV is silent until late liver disease. There is no vaccine.

What is hepatitis c?
Hepatitis C is a viral infection of the liver. Around 75-85% of people who acquire HCV develop chronic infection, which over decades can lead to cirrhosis, liver failure and liver cancer.
Modern direct-acting antivirals (DAAs) cure over 95% of HCV in 8-12 weeks - one of the most dramatic therapeutic advances in modern medicine. The barrier is now detection: chronic HCV is silent and many carriers are unaware.
Pathogen: Hepatitis C virus (HCV) (Enveloped RNA virus, Flaviviridae).
How it spreads
- Sharing needles or injection equipment - the dominant route
- Unscreened blood transfusion or organ transplant (pre-1990s)
- Mother-to-baby (~5% vertical transmission)
- Tattoo, piercing, acupuncture or medical procedures with unsterilised equipment
- Sexual transmission - low risk overall, higher in HIV-positive MSM with rough/unprotected receptive anal sex
- Sharing razors, toothbrushes - rare but possible
Who is at risk? Should I get tested?
- People who have ever injected drugs (even once, decades ago)
- Anyone who received a blood transfusion in Malaysia before 1992
- Tattoos, piercings or medical/dental procedures with unsterilised equipment
- HIV-positive men who have sex with men (sexual HCV transmission documented)
- Healthcare workers with needlestick exposure
- Children of HCV-positive mothers
- People living with HIV
Should I get tested? Quick self-check
Answer the questions below - your concierge can advise on the next step.
- Have you ever injected drugs, even once?
- Did you receive a blood transfusion in Malaysia before 1992?
- Have you had a tattoo, piercing or medical procedure with shared equipment?
- Are you HIV-positive, particularly with anal sex exposure?
- Have you had a needlestick injury at work?
- Do you have unexplained elevated liver enzymes or fatigue?
Symptoms
- Most acute HCV infections cause no symptoms
- Mild fatigue, nausea, abdominal discomfort
- Jaundice (uncommon)
- Chronic HCV is usually silent for 20-30 years
- Late-stage cirrhosis: fluid retention, easy bruising, jaundice, confusion
- Liver cancer in advanced cirrhosis
Asymptomatic in men
Around 80% of acute HCV infections have no symptoms; chronic HCV is silent for 20-30 years
Asymptomatic in women
Same as men - silent until late-stage liver disease in most cases

Malaysia statistics
| Estimated Malaysians living with chronic HCV | ~400,000 (1-2% of population)[2] |
| Predominant transmission route in Malaysia | Injection drug use[2] |
| HCV/HIV co-infection prevalence among Malaysian PWID | Up to 80%[3] |
| Cure rate with modern direct-acting antiviral therapy | >95%[1] |
| Global elimination target (WHO) | By 2030[1] |
Testing & window period
Method
Step 1: anti-HCV antibody (screening). Step 2 if positive: HCV RNA PCR to confirm current infection. Genotype is determined for treatment.
Specimen
Venous blood
Window period
Anti-HCV antibodies detectable 8-11 weeks post-exposure; HCV RNA from 1-2 weeks. Repeat at 3 and 6 months if initial negative and recent exposure.
Retest
After cure: HCV RNA at 12 weeks post-treatment confirms sustained virological response (SVR = cure). Anti-HCV antibodies remain positive for life despite cure - this is normal.
Treatment
First-line: A short oral course of direct-acting antiviral therapy, prescribed by our medical team in co-management with a hepatologist. Cure rates exceed 95%.
Alternative: Tailored regimens are available for cirrhosis, decompensated liver disease, or prior treatment failure - all under hepatologist co-management.
Partner management: Test partners only if shared injection equipment, or for HIV-positive MSM. Routine sexual partner notification is not generally needed except in those contexts.
Treatment is well-tolerated. Liver imaging is performed before treatment to stage fibrosis. Chronic HCV with advanced cirrhosis still requires ongoing cancer surveillance even after cure.
Follow-up
- HCV RNA at 12 weeks post-treatment confirms cure (SVR12)
- Annual liver imaging for cirrhosis cases even after cure
- Reinfection screening if ongoing exposure
- Vaccinate against hepatitis A and B (any remaining gaps) and ensure HIV testing
Prevention
- Never share needles or injection equipment
- Use sterile equipment for tattoos, piercings, acupuncture
- Condoms for HIV-positive MSM (HCV transmission risk is higher)
- Screen blood donors (universal in Malaysia)
- Universal precautions in healthcare settings
Vaccination
No hepatitis C vaccine exists. Prevention relies on harm reduction and avoiding blood-to-blood exposure.
