Quick Answer
A common symptom of hepatitis A is fatigue, often with nausea and loss of appetite. Jaundice - yellowing of the eyes and skin - is another classic sign, but it does not occur in everyone. Per CDC, symptoms can begin about 2 to 7 weeks after exposure.
- Fatigue and nausea are common early hepatitis A symptoms.
- Jaundice may appear a few days after initial tiredness and nausea.
- Dark urine and clay-colored stools often accompany hepatitis A jaundice.
- Per CDC, children under six often have no noticeable hepatitis A symptoms.
- Hepatitis A spreads fecal-oral, while hepatitis B and C spread through blood or sexual contact.
- Symptoms usually begin two to seven weeks after exposure, according to CDC.
Symptom Breakdown by Infection
Hepatitis A is a liver infection caused by the hepatitis A virus, which is spread mainly when a person ingests food, water, or objects contaminated with tiny amounts of stool from an infected person. Once inside the body, the virus travels to the liver and triggers immune inflammation. That inflammation, not the virus alone, produces many symptoms: the liver temporarily struggles to process bilirubin and other wastes. Young children often clear the infection with few or no signs, while older children and adults are more likely to feel ill. Symptoms may build gradually or appear suddenly, and they can last for weeks.
| Infection | Classic signs |
|---|---|
| Chlamydia | Usually none. When present: watery discharge, burning urination, testicular ache, bleeding between periods. |
| Gonorrhea | Yellow-green discharge, painful urination, rectal itching; throat infections rarely announce themselves. |
| Syphilis | A painless round sore (chancre), then palm/sole rash, fever, and swollen nodes in stage two. |
| HIV | Half get acute flu-like illness 2–4 weeks in: fever, sore throat, rash, night sweats. |
| Genital herpes (HSV) | Tingling then clusters of small blisters that crust over; first outbreak is the worst. |
| HPV (human papillomavirus) | Usually invisible. Some strains cause warts; high-risk types stay silent until screening finds changes. |
| Trichomoniasis | Frothy yellow-green discharge with strong odor (women); most men notice only mild irritation. |
| Hepatitis B | Fatigue, dark urine, jaundice, right-upper abdominal pain when symptomatic. |
| Hepatitis C | Mostly silent for years; fatigue and brain fog may be the only hints until liver damage advances. |
When Symptoms Point Somewhere Else
Urinary burning can come from bladder infections rather than STIs, genital itching from yeast or dermatitis, and pelvic pain from non-sexual causes. That overlap is precisely why guessing fails and testing wins: the same discharge pattern can mean three different conditions requiring three different treatments.
