- Poor Sanitation Practices: Food handlers who do not wash their hands properly after using the restroom can spread the virus through food.
It’s important to note that hepatitis A is not transmitted through sexual contact or casual contact like hugging or shaking hands.
Symptoms of Hepatitis A
Symptoms of hepatitis A can vary in severity and may not appear until several weeks after exposure. When they do occur, symptoms can include:
Common Symptoms
- Fatigue
- Nausea and vomiting
- Abdominal pain or discomfort
- Loss of appetite
- Low-grade fever
- Dark urine
- Jaundice (a yellowing of the skin and eyes)
How Long Does it Last?
In most cases, hepatitis A symptoms last between a few weeks to several months. The majority of people who contract the virus recover completely without any lasting liver damage.
High-Risk Food and Water Sources
Understanding where the hepatitis A virus can thrive is essential for preventing infection. Here are some high-risk sources that individuals should be aware of:
