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.

Single green seedling pushing through cracked earth - hepatitis C is curable.

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.

Patogen: Hepatitis C virus (HCV) (Enveloped RNA virus, Flaviviridae).

Bagaimana ia tersebar

  • 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

Siapa yang berisiko? Haruskah saya diuji?

  • 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

  • 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?

Gejala

  • 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

Tanpa gejala pada lelaki

Around 80% of acute HCV infections have no symptoms; chronic HCV is silent for 20-30 years

Tanpa gejala pada wanita

Same as men - silent until late-stage liver disease in most cases

Ujian & tempoh jendela

Kaedah

Step 1: anti-HCV antibody (screening). Step 2 if positive: HCV RNA PCR to confirm current infection. Genotype is determined for treatment.

Spesimen

Venous blood

Tempoh jendela

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.

Ujian semula

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.

Rawatan

Barisan pertama: A short oral course of direct-acting antiviral therapy, prescribed by our medical team in co-management with a hepatologist. Cure rates exceed 95%.

Alternatif: Tailored regimens are available for cirrhosis, decompensated liver disease, or prior treatment failure - all under hepatologist co-management.

Pengurusan pasangan: 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.

Susulan

  • 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

Pencegahan

  • 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

Vaksinasi

No hepatitis C vaccine exists. Prevention relies on harm reduction and avoiding blood-to-blood exposure.

FAQ

Hepatitis C - frequently asked questions

Clear answers, written by our clinical team. Tap any question for its direct permalink, or reach out to your Personal Concierge for anything else.

  1. Can hepatitis C be cured?

    Yes. Modern direct-acting antiviral therapy cures over 95% of HCV with a short course of well-tolerated oral medication. Cure is confirmed by undetectable HCV RNA 12 weeks after treatment ends.

  2. If I am cured, will my antibody test be negative?

    No - the anti-HCV antibody remains positive for life even after cure. Active infection is monitored using HCV RNA PCR, which becomes and stays negative after successful treatment.

  3. Should I be tested if I had a transfusion in the 1980s?

    Yes. Blood was not routinely screened for HCV in Malaysia until 1992. A one-off anti-HCV antibody test is recommended for anyone who received blood products before that date.

  4. Can I catch HCV from sex?

    Sexual HCV transmission is uncommon overall - the risk is higher in HIV-positive MSM, particularly with unprotected receptive anal sex. Routine condom use is recommended in that context.

  5. Is there a hepatitis C vaccine?

    No - there is no HCV vaccine. Hepatitis A and B vaccines are unrelated and do not protect against HCV. Prevention relies on avoiding blood-to-blood exposure.

  6. How is HCV care arranged at Hisential?

    Your personal health concierge coordinates antibody screening, RNA confirmation, hepatologist referral, DAA treatment and cure confirmation in one confidential pathway.
