TYPES
Infectious hepatitis, also known as viral hepatitis, encompasses several types of hepatitis caused by different viruses. Here are the main types of infectious hepatitis:
1. Hepatitis A (HAV): Hepatitis A is a highly contagious virus that spreads through the ingestion of contaminated food or water, or close contact with an infected person. It causes acute hepatitis, usually resolving on its own without chronic complications. Hepatitis A can be prevented through vaccination and practicing good hygiene.
2. Hepatitis B (HBV): Hepatitis B is transmitted through contact with infected blood, semen, vaginal fluids, and other body fluids. It can be spread through unprotected sex, sharing needles, or from mother to child during childbirth. HBV infection can result in both acute and chronic hepatitis, with chronic infection potentially leading to liver cirrhosis, liver failure, or liver cancer. Vaccination, safe sex practices, and avoiding sharing needles are important preventive measures.
3. Hepatitis C (HCV): Hepatitis C is mainly transmitted through contact with infected blood, often through sharing needles, receiving blood transfusions or organ transplants before proper screening, or less commonly through sexual contact or from mother to child during childbirth. HCV can cause chronic hepatitis, which may progress to liver cirrhosis, liver failure, or liver cancer. There is no vaccine for HCV, and prevention involves using sterile needles, screening blood donations, and practicing safe sex.
4. Hepatitis D (HDV): Hepatitis D is a virus that can only infect individuals already infected with HBV, as it requires the presence of HBV to replicate. HDV can cause more severe liver disease than HBV alone. Prevention of HDV involves preventing HBV infection through vaccination.
5. Hepatitis E (HEV): Hepatitis E is primarily transmitted through contaminated water or food, especially in areas with poor sanitation. It typically causes acute hepatitis, but pregnant women, particularly in their third trimester, can experience severe complications. Improving sanitation and practicing good personal hygiene are key preventive measures for hepatitis E.
SYMPTOMS
The symptoms of infectious hepatitis can vary depending on the specific type of virus causing the infection. However, there are some common symptoms that may occur in various forms of viral hepatitis. Here are the general symptoms associated with infectious hepatitis:
1. Fatigue: Feeling excessively tired or lacking energy is a common symptom of hepatitis. It may persist for weeks or even months.
2. Jaundice: Yellowing of the skin and eyes is a hallmark symptom of hepatitis. It occurs due to the buildup of bilirubin, a yellow pigment, in the body.
3. Abdominal pain: Many individuals with hepatitis experience discomfort or pain in the abdominal area, typically in the upper right quadrant where the liver is located.
4. Loss of appetite: A decrease in appetite and consequent weight loss can occur in hepatitis, as individuals may feel full or nauseous.
5. Nausea and vomiting: Hepatitis can cause feelings of nausea, occasionally leading to vomiting.
6. Muscle and joint aches: Some people with hepatitis may experience muscle and joint pain, often described as flu-like symptoms.
7. Fever: Mild to moderate fever can occur in hepatitis, particularly in the acute phase of the infection.
8. Dark urine and pale stools: Hepatitis can cause changes in urine and stool color. Urine may become darker, while stools may appear pale or clay-colored.
It is important to note that not everyone infected with hepatitis will experience symptoms, especially in the early stages of the disease. Additionally, the severity and duration of symptoms can vary among individuals and different types of viral hepatitis.
If you suspect you have hepatitis or have been exposed to the virus, it is recommended to seek medical attention for proper diagnosis and guidance on treatment. A healthcare professional can perform diagnostic tests and provide appropriate care based on your specific situation.
5. Numbness or tingling: In rare cases, low potassium levels can cause numbness or tingling sensations in the limbs.
