Vaccination is the most effective method for preventing hepatitis B, a serious liver infection that can lead to acute or chronic complications.
Medical experts emphasize that vaccination is the best prevention method for hepatitis B, a liver infection that can manifest in both acute and chronic forms. This viral infection has no cure and may result in a range of serious complications.
The U.S. Department of Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. and his advisory group are scheduled to meet this week to discuss and vote on various vaccine recommendations, including those for hepatitis B, COVID-19, and measles, mumps, and rubella.
Hepatitis B is recognized as a significant viral infection that causes inflammation in the liver and is the most prevalent liver infection globally, according to the Cleveland Clinic. The World Health Organization estimates that approximately 254 million people worldwide are currently living with this infection.
The infection can present as acute hepatitis B, which is typically brief, or as chronic hepatitis B, which can lead to severe complications such as cirrhosis (scarring of the liver) and liver failure. The virus is transmitted through exposure to infected bodily fluids, including blood, saliva, and other secretions. Common routes of transmission include unprotected sexual contact, sharing needles or syringes, and the use of contaminated medical instruments. Additionally, a pregnant woman can pass the virus to her newborn during childbirth, as noted by the Mayo Clinic.
While anyone can contract hepatitis B, certain individuals are at a higher risk. This includes those with sexually transmitted infections, individuals undergoing immunosuppressive treatments (such as chemotherapy), patients receiving dialysis, and those with other liver diseases.
Although the viral infection does not always present symptoms, some common signs include abdominal pain, fatigue, fever, joint pain, loss of appetite, nausea, vomiting, and weakness. Other symptoms indicative of liver disease may include dark-colored urine, light or clay-colored stool, jaundice (yellowing of the skin and eyes), and swelling due to fluid accumulation in the abdomen, arms, and legs.
A person remains contagious as long as the virus is active in their body. Acute hepatitis B can last for up to six months, while individuals with active chronic hepatitis B can remain contagious indefinitely. In contrast, those with inactive chronic hepatitis B have a lower risk of transmission.
Both acute and chronic forms of hepatitis B can lead to various complications, including acute and chronic liver failure, cirrhosis, hepatitis D, and liver cancer, according to health experts.
Diagnosis of hepatitis B typically involves blood tests, imaging tests such as elastography of the liver tissue, or a liver biopsy. Blood tests can determine whether the virus is active or inactive.
While there is no cure for hepatitis B, certain antiviral medications can help make the virus inactive. In chronic cases, these medications must be taken indefinitely. If the infection progresses to cancer, surgical options may include removing part of the liver or, in severe cases, a liver transplant.
Vaccination remains the most effective way to prevent hepatitis B infection. The Centers for Disease Control and Prevention (CDC) recommends hepatitis B vaccination for all infants, children under 19, adults aged 19 to 59, and individuals over 60 who have risk factors. Various hepatitis B vaccines are available, each requiring different dosing schedules.
The Cleveland Clinic advises individuals with hepatitis B to avoid alcohol, maintain a healthy diet, protect themselves from other liver infections, and seek support as needed. They note, “If tests show you have hepatitis B, you may wonder how the disease will change your life. You may worry about spreading the virus to others. The good news is there are medications that keep chronic hepatitis B from spreading. And there are steps you can take to protect your overall health and protect others.”
