Yes — you can have hepatitis B or C and feel completely fine. Both infect the liver, both spread through blood and (for hepatitis B) sex, and both are frequently silent. Many people with hepatitis B have no symptoms at all, and most hepatitis C infections cause none for years. A blood test tells you which one (if any) you have.

The symptoms of hepatitis B, explained
Hepatitis B is a vaccine-preventable liver infection caused by the hepatitis B virus (HBV) CDC, About HBV. The first six months after exposure are called acute infection; if the virus sticks around beyond that, it's chronic and can be lifelong. When acute hepatitis B does cause symptoms, they reflect a liver that's inflamed and struggling to do its normal jobs of filtering blood and processing waste.
- Fatigue — a deep, persistent tiredness that rest doesn't fix, because an inflamed liver disrupts the body's energy and metabolic processing.
- Fever and joint pain — your immune system mounting a response to the virus, which can feel flu-like.
- Poor appetite and nausea — the liver's role in digestion falters, so food becomes unappealing and the stomach unsettled.
- Abdominal pain — usually in the upper right, where the liver sits, as the inflamed organ swells against its capsule.
- Dark urine — when the liver can't clear bilirubin (a yellow pigment from broken-down red blood cells), it spills into urine and turns it tea- or cola-colored.
- Clay-colored stools — bile that normally gives stool its brown color isn't reaching the gut, so stools turn pale.
- Jaundice — a yellow tint to the skin and the whites of the eyes from that same bilirubin buildup; it's the most recognizable sign of liver trouble.
Many people with acute hepatitis B notice none of this, and most people with chronic HBV are asymptomatic for years. Feeling well is not evidence you're uninfected. That's one of the most common ways the infection goes undetected.
Where the signs show up — and the ones that are easy to miss
The two findings most people picture are yellow eyes and dark urine, and those sit at the late, visible end of the spectrum. The earlier signs are vague and easy to brush off: low energy, a poor appetite, achy joints, mild queasiness. People often attribute these to stress, a busy stretch, or a virus that's "going around." Jaundice and clay-colored stools tend to appear only once liver inflammation is well established, so waiting for the obvious sign means waiting too long. For a fuller breakdown of each, see our guide to hepatitis b symptoms.
How soon symptoms appear after exposure
Hepatitis B has a long incubation period. On average it's about 90 days from exposure to symptom onset, with a typical range of 60 to 150 days CDC surveillance. Hepatitis C is quicker on average — symptoms, when they occur at all, show up around 2 to 12 weeks after exposure, with a wider range of 2 to 26 weeks CDC, About HCV. Both timelines matter for testing, because antibodies and viral markers take time to become detectable; see when to test after exposure before you assume a single early test rules anything out.
How hepatitis C symptoms differ
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV), spread when infected blood enters another person. Most people who catch it develop chronic, lifelong infection, and the symptom picture is even quieter than hepatitis B. Jaundice occurs in only about 20–30% of acute infections, and nonspecific symptoms like fatigue, poor appetite, abdominal pain, or dark urine in roughly 10–20% CDC clinical overview. Chronic hepatitis C frequently causes no specific symptoms for 20 years or more, quietly scarring the liver in the background. Unlike hepatitis B, hepatitis C is now curable, with treatment clearing the virus in more than 95% of people. We cover what that course of pills looks like on our hepatitis c cure page.
What people commonly mistake these symptoms for
Because the early symptoms are nonspecific, they get blamed on almost anything else first:
- A lingering cold or the flu — fever, body aches, and fatigue overlap heavily, especially early on.
- Burnout or stress — fatigue and poor appetite are easy to attribute to a hard month.
- A stomach bug — nausea and upper-abdominal discomfort can read as gastroenteritis.
- Dehydration or vitamins — dark urine is often shrugged off as "I haven't had enough water" rather than a bilirubin problem.
Hepatitis B, hepatitis C, and several other liver and viral illnesses overlap too much to tell apart by sight, and several are frequently silent. You usually can't self-diagnose this. A test settles which one (if any) it is.
How it's confirmed
Hepatitis B is confirmed with a triple blood panel — HBsAg for active infection, anti-HBs for immunity or recovery, and total anti-HBc for past or current infection CDC HBV testing. Hepatitis C starts with an antibody test; a positive result triggers an automatic NAT for HCV RNA to confirm current infection CDC HCV testing. You don't need to interpret these alone. A clinician orders the right combination and explains what the pattern means. Here's how to get tested.
The screening case (even with zero symptoms)
Because both infections hide for years, screening isn't tied to feeling sick. The CDC (2023) recommends screening all adults aged 18 and older for hepatitis B at least once in their lifetime, and pregnant people each pregnancy CDC MMWR 2023. For hepatitis C, the CDC recommends one-time screening for all adults 18 and older and each pregnancy, and the USPSTF gives one-time screening for adults aged 18–79 a Grade B recommendation USPSTF. Testing is usually a quick blood draw or sample, free or low-cost at health departments, Planned Parenthood, and Title X clinics, with results typically back in a few days.
When to see a clinician
Get evaluated promptly if you develop jaundice (yellow skin or eyes), persistent dark urine, clay-colored stools, or unexplained right-upper-abdominal pain — those point to active liver inflammation. Also seek testing, even without symptoms, if you've had a known exposure, are due for routine screening, are pregnant, or have a sexual partner diagnosed with hepatitis B or C. The most consequential cases are the silent ones caught only because someone got tested, so don't wait for the obvious signs.
