Hepatitis A and B are viral infections that affect the liver. Here's a brief overview of each:

Hepatitis A (HAV):

Transmission: Usually spreads through contaminated food or water, or by close contact with an infected person.

Symptoms: Symptoms may include fever, fatigue, nausea, abdominal pain, and jaundice.

Prevention: Vaccination is an effective preventive measure. Good hygiene practices, such as handwashing, also help prevent its spread.

Hepatitis B (HBV):

Transmission: Primarily spreads through contact with blood or other body fluids of an infected person. It can be transmitted through unprotected sex, sharing needles, or from an infected mother to her baby during childbirth.

Symptoms: Some individuals may not show symptoms, but others may experience fatigue, abdominal pain, dark urine, and jaundice.

Prevention: Vaccination is the key preventive measure. Using protection during sexual activity and avoiding sharing needles are also important to prevent transmission.

Vaccination is highly recommended for both hepatitis A and B, especially for individuals at higher risk due to travel, occupation, or lifestyle factors. If you have concerns or specific questions about hepatitis or vaccinations, it's advisable to consult with a healthcare professional.
