Hepatitis is an inflammation or swelling of the liver, and it can be the result of a viral infection or over-exposure to harmful substances such as drugs and alcohol 코렐드로우 x7 다운로드. There are three main types of hepatitis, and while some types pass without causing permanent liver damage, others can be present for years and cause scarring of the liver (cirrhosis), and in serious cases liver failure.
Types of hepatitis
Hepatitis A is the most common form of hepatitis, and it’s transmitted by eating or drinking something that’s been contaminated by the faeces of someone with hepatitis A. This can happen by eating food that’s been prepared by an infected person who hasn’t washed their hands after going to the toilet, or through contaminated water. Hepatitis A is usually a short-term infection, and symptoms pass within 3 months. While there is no cure, treatment involves symptomatic support and dietary changes in the form of a low-fat diet and eliminating alcohol for at least 6 months. There is a Hepatitis A vaccination available.
Hepatitis B is found in body fluids such as semen, vaginal fluids and blood. This means it can be spread through unprotected sex or by sharing intravenous drug needles. Hepatitis B is common in countries such as China, central and Southeast Asia and sub-Saharan Africa.
Most people who contract Hepatitis B make a full recovery within a couple of months, without any permanent damage. However, some people develop a long-term infection known as chronic hepatitis B, which can lead to cirrhosis and an increased risk of liver cancer. It can be treated with antiviral medication, and there is a Hepatitis B vaccination available.
Hepatitis C is mostly concentrated in the blood. This means it’s usually transmitted through blood-to-blood contact, for example through needles that have infected blood on it. This is a high-risk if blood or needles are used more than once. Hepatitis C can also be transmitted when getting a tattoo or a piercing with a needle that has infected blood on it. This can happen if equipment isn’t cleaned properly after it is used.
It’s also possible for a mother to spread the Hepatitis C virus to her baby at birth.
When it comes to symptoms, Hepatitis C often doesn’t present with noticeable symptoms, or they’re mistaken for the flu, so many people don’t even know they’re infected. As with Hepatitis B, Hepatitis C can develop into a long-term infection. There is currently no vaccination for it.
