Hepatitis A is a viral infection that affects the liver. It is caused by the hepatitis A virus (HAV), which is primarily spread through the consumption of contaminated food or water, or through close contact with an infected person. The virus infects the liver and causes inflammation, which can lead to symptoms such as fever, fatigue, nausea, vomiting, abdominal pain, and jaundice (yellowing of the skin and eyes). Hepatitis A is generally a self-limited illness, meaning it typically resolves on its own without treatment. However, in some cases, the infection can lead to severe liver damage or even liver failure, particularly in older adults or people with pre-existing liver disease. Hepatitis A can be prevented through vaccination and by practicing good hygiene, such as washing your hands frequently and avoiding food or water that may be contaminated.
The symptoms of Hepatitis A can vary in severity, but commonly include:
Fatigue
Nausea and vomiting
Abdominal pain or discomfort
Loss of appetite
Jaundice (yellowing of the skin and eyes)
Dark urine
Joint pain
Fever
Itching
These symptoms can last for several weeks, but most people recover fully without any long-term liver damage. However, in rare cases, Hepatitis A can cause acute liver failure, which can be life-threatening. If you suspect you may have Hepatitis A, it is important to see a healthcare professional for diagnosis and treatment.
