Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). It can spread quickly through contaminated food, water, or close contact with an infected person. According to the World Health Organization (WHO), there are approximately 144,000 cases of hepatitis A reported globally each year. Understanding the early signs and symptoms of hepatitis A is crucial for prompt medical attention and effective treatment. In this article, we will explore the key indicators of hepatitis A, risk factors, and preventive measures to help you catch the infection early on.
What is Hepatitis A and How is it Transmitted?
Hepatitis A is a viral infection that primarily affects the liver, causing inflammation and damage. The virus is highly contagious and can be spread through:
- Contaminated food and water: Eating food or drinking water that has come into contact with the virus can lead to infection.
- Close contact with an infected person: Direct contact with someone who has the virus, such as through shaking hands or sharing utensils, can spread the infection.
- Poor hygiene: Not washing hands regularly, especially after using the bathroom or before handling food, can contribute to the spread of the virus.
Early Signs and Symptoms of Hepatitis A
The early signs and symptoms of hepatitis A can be similar to those of other viral infections, making it essential to be aware of the specific indicators. Common symptoms include:
| Symptom | Description |
