Hepatitis B is a serious liver infection caused by the Hepatitis B virus (HBV). This virus can lead to both acute (short-term) and chronic (long-term) illness. If left untreated, chronic Hepatitis B can cause severe liver damage, including cirrhosis, liver failure, and liver cancer, which can be life-threatening. The good news is that a safe and highly effective vaccine is available to prevent Hepatitis B.
HBV is primarily transmitted through contact with infected blood, semen, or other bodily fluids. The virus is not spread through food, water, or casual contact.
Have unprotected sex with an infected person.
Share needles or syringes.
Are born to an infected mother.
Have occupational exposure to blood (e.g., healthcare workers).
Share personal items, such as razors or toothbrushes, that may have traces of blood.
Many people, especially children, with an acute HBV infection may not show any symptoms. When they do appear, symptoms can be mild to severe and typically show up 1 to 4 months after exposure.
Acute Hepatitis B symptoms can include:
You can significantly reduce the risk of contracting Hepatitis B by taking these key preventive measures:
Vaccination: The Hepatitis B vaccine is safe, highly effective, and provides long-term protection.
Safe Sex Practices: Use condoms consistently and correctly during sexual activity.
Avoid Sharing Needles: Never share needles, syringes, or other drug injection equipment.
Do Not Share Personal Items: Avoid sharing razors, toothbrushes, or nail clippers.
Safe Injection Practices: Healthcare workers should adhere to universal precautions to avoid occupational exposure.
Hepatitis B is diagnosed with a simple blood test that detects HBV antigens and antibodies, indicating whether you have an active infection, a past infection, or are immune.
Testing is recommended for:
While there is no cure for chronic Hepatitis B, antiviral medications can effectively manage the infection. These medications help slow down liver damage and reduce the risk of developing liver cancer. For acute Hepatitis B, treatment typically focuses on supportive care as your body fights off the infection on its own.
If you have successfully cleared an acute infection or are vaccinated, you develop protective antibodies and are generally immune. However, if you have chronic Hepatitis B, you will always carry the virus, and the goal of treatment is to manage it, not eliminate it.
Hepatitis C is a liver infection caused by the Hepatitis C virus (HCV). Most people who become infected with HCV will develop a chronic illness. Without treatment, this can lead to serious liver problems like cirrhosis, liver failure, and liver cancer. The good news is that, unlike Hepatitis B, highly effective antiviral medications can cure Hepatitis C for most people.
HCV is primarily spread through blood-to-blood contact with an infected person. Sexual transmission is less common but can occur, especially among those with multiple partners or other STIs.
You are at risk if you:
Many people with Hepatitis C have no symptoms in the early stages and may not know they are infected until significant liver damage has occurred. When symptoms do appear, they can be mild and non-specific.
Hepatitis C symptoms can include:
Symptoms of advanced liver disease may also include fluid retention, easy bleeding, bruising, and confusion.
Since there is currently no vaccine for Hepatitis C, prevention focuses on avoiding blood-to-blood contact.
Testing for Hepatitis C is done through blood tests that can detect HCV antibodies (indicating exposure) or HCV RNA (indicating active infection).
Testing is recommended for:
Yes, Hepatitis C is curable for most people! Highly effective direct-acting antiviral (DAA) medications have revolutionized treatment. These medications typically involve a short course of oral pills (8-12 weeks) and boast cure rates of over 95%.
Being cured of Hepatitis C does not make you immune to future infections. You can be re-infected if you are exposed to the virus again, which is why it is important to continue practicing preventive measures even after successful treatment.
Both are viruses that cause liver inflammation, but they are different viruses. The main differences are that there is a vaccine for Hepatitis B, but no cure for chronic infection, while there is no vaccine for Hepatitis C, but a highly effective cure is available.
Both viruses are primarily spread through contact with infected blood, but Hepatitis B is also commonly spread through semen and other bodily fluids via sexual contact. Hepatitis C is less commonly sexually transmitted.
There is a safe and effective vaccine for Hepatitis B. There is currently no vaccine available for Hepatitis C.
Hepatitis B has no cure, but its chronic form can be managed with antiviral medications. Hepatitis C, however, is curable for most people with a short course of medication.
If left untreated, both chronic Hepatitis B and C can lead to severe liver damage, including cirrhosis, liver failure, and liver cancer, which can be fatal.
If you have successfully recovered from Hepatitis B, you are generally immune. However, if you are cured of Hepatitis C, you can get re-infected if you are exposed to the virus again.
