The incubation period for Hepatitis A is typically:

Explanation:
Incubation period is the time between exposure to the virus and the first signs of illness. For Hepatitis A, this period is typically 15 to 50 days, often around 2 to 4 weeks after exposure. This window exists because the virus must replicate in the liver and reach a level that produces noticeable symptoms. That range matches how HAV behaves in most people and helps public health investigators determine when someone may have been exposed and who else might be at risk. Times like 1–2 days or 6–8 hours would imply a very rapid onset more typical of toxin-mediated illness, not a viral hepatitis. A span of 90–120 days is much longer than what is observed with HAV.
