Hepatitis B remains a global health challenge.. There are strategies to prevent perinatal (mother to child) transmission of hepatitis B. Prevention includes testing all pregnant persons for the marker of hepatitis B infection (HBsAg), if the pregnant person is positive, then assessment is needed throughout pregnancy. If the pregnant person’s viral load becomes high, antiviral treatment (TDF) might be recommended during the second trimester taken throughout pregnancy. Data shows this is safe and effective, and reducing the viral load can reduce the risk of transmission.  

Additionally, making sure that all infants get hepatitis B birth dose as soon as possible after delivery, ideally within the first 24 hours of birth followed by at least two subsequent doses of hepatitis B vaccine (usually part of global childhood immunization series ex: the pentavalent vaccination). However, for many individuals, adhering to these guidelines in many parts of the world can be a challenge. Recent research sheds light on the barriers and opportunities to improve treatment adherence during this important period. Treatment adherence means taking your medicine the right way, at the right time, in the right amount, and for as long as your doctor tells you. It’s about sticking to your treatment plan to maintain your health.  

The postpartum drop-off: a hidden risk 

A study published in the Journal of the Pediatric Infectious Diseases Society explored adherence to tenofovir disoproxil fumarate (TDF), a medication used to treat HBV, among pregnant individuals. While adherence during pregnancy was relatively high, many women discontinued treatment postpartum. A mix of factors contributed to the drop in HBV treatment adherence following delivery including:  

  • Lack of follow-up care after delivery 
  • Low awareness about health risks that may come from stopping medication 
  • Limited knowledge about the long-term benefits of continued treatment 
  • Healthcare system gaps, especially in low-resource settings, making access to care and medication difficult 

What the numbers say?

In a broader context, a study from Israel found that only about 67% of chronic HBV patients maintained high adherence (defined as taking at least 80% of the prescribed medication). Many women stopped taking their medication after giving birth or were not consistent with their medication routines (Mor et al., 2022). A 2025 pilot study published in Virology Journal looked at what happens when women with chronic hepatitis B stop taking antiviral medication after giving birth. Among 88 women who discontinued treatment postpartum, nearly 29% experienced liver inflammation (ALT flares)—a sign that the virus was becoming elevated (Tang et al., 2025).  

What can be done? 

Improving postpartum adherence to HBV treatment requires a holistic approach and strategies can include: 

  • Integrated care models that link obstetric and hepatology services, making it easier for women to stay on track with their hepatitis B care and medication 
  • Patient education that emphasizes the importance of continued treatment beyond pregnancy 
  • Support from community health workers to provide follow-up and encouragement to stay connected with hepatitis B care 
  • Mobile health tools (like SMS reminders) to help new mothers stay on track after delivery 

The postpartum period is a time of immense change—and often, medical follow-up takes a backseat. But for women living with HBV, taking efforts to prevent perinatal transmission is crucial not just for their own health, but for preventing the future generation from hepatitis B. With better systems, education, and support, we can close the adherence gap and protect more lives.

About Hepatitis B, Hepatitis B Prevention

What’s the Difference: Hepatitis A vs Hepatitis B

With five different types of viral hepatitis, it can be difficult to understand the differences between them. Some forms of hepatitis get more attention than others, but it is still important to know how they are transmitted, what they do, and the steps that you can take to protect yourself and your liver!

This is part two in a three-part series.

What is Hepatitis?

Hepatitis means “inflammation of the liver”. A liver can become inflamed for many reasons, such as too much alcohol, physical injury, autoimmune response, or a reaction to bacteria or a virus. The five most common hepatitis viruses are A, B, C, D, and E. Some hepatitis viruses can lead to fibrosis, cirrhosis, liver failure, or even liver cancer. Damage to the liver reduces its ability to function and makes it harder for your body to filter out toxins.

Hepatitis A vs. Hepatitis B

While hepatitis A and B both impact the liver, the two viruses differ greatly from one another. Hepatitis B is a blood-borne pathogen; its primary mode of transmission is through direct blood-to-blood contact with an infected person. In contrast, hepatitis A can be spread by fecal-oral transmission or by consuming food or water that has been contaminated. It is important to note that a person cannot contract hepatitis B through casual interactions such as holding hands, sharing a meal with, or eating foods prepared by someone who is infected. There is no need to keep plates and utensils separate. However, hepatitis A can be spread through food that is prepared by an infected person. Hepatitis A is primarily caused by poor sanitation and personal hygiene. Poor sanitation and hygiene can be the result of a lack of essential infrastructure like waste management or clean water systems. It can also result from a lack of education.

Hepatitis A is an acute infection; the virus typically stays in the body for a short amount of time and most people make a full recovery after several weeks. Recently, the United States has seen a rise in hepatitis A infections. The rise is partially attributed to a growing homeless population and increases in injection drug use. You can track hepatitis A outbreaks in the United States by using this map.

Unlike hepatitis B, which rarely has symptoms, people infected with hepatitis A generally develop symptoms four weeks after exposure. However, children under the age of 6 often do not show any symptoms. Oftentimes, an infected adult will experience nausea, vomiting, fever, dark urine, or abdominal pain. Older children and adults with hepatitis A will typically experience jaundice, according to the Centers for Disease Control and Prevention (CDC). Once a person makes a recovery, they cannot be reinfected. Their body develops protective antibodies that will recognize the virus and fight it off if it enters their system again. Hepatitis A rarely causes lasting liver damage, but in a small percentage of individuals, it can cause acute liver failure called fulminant hepatitis. Some people with hepatitis A feel ill enough that they need to be hospitalized to receive fluids and supportive care.

On the other hand, hepatitis B begins as a short-term infection, but in some cases, it can progress into a chronic, or life-long, infection. Chronic hepatitis B is the world’s leading cause of liver cancer and can lead to serious liver diseases such as cirrhosis or liver cancer. Most adults who become infected with hepatitis B develop an acute infection and will make a full recovery in approximately six months. However, about 90% of infected newborns and up to 50% of young children will develop a life-long infection. This is because hepatitis B can be transmitted from an infected mother to her baby due to exposure to her blood. Many infected mothers do not know they are infected and therefore cannot work with their physicians to take the necessary precautions to prevent transmission. It is extremely important for all pregnant women to get tested for the hepatitis B – if they are infected, transmission to their baby can be prevented!

There are vaccines to protect people against both hepatitis A and hepatitis B. If you are unvaccinated and believe that you have been exposed to hepatitis A, you should contact your doctor or local health department to get tested. If you were exposed by consuming contaminated food, the health department can work with you to identify the source of exposure and prevent a potential outbreak. Depending on the situation and when you were exposed, your doctor may administer postexposure prophylaxis (PEP) to help prevent the infection or lessen its impact. For hepatitis A, PEP is given in the form of one dose of the vaccine or immune goblin.

For unvaccinated individuals, PEP is also recommended after a possible exposure to hepatitis B and is usually given as a dose of the vaccine. In certain cases, a physician will recommend that a patient receive both the vaccine and a dose of hepatitis B immune globulin (HBIG) for additional protection. As recommended by the CDC, all infants born to hepatitis B surface antigen positive mothers (HBsAg positive) should receive both a dose of the hepatitis B vaccine and a dose of HBIG within 12 hours of birth in order to prevent transmission. As timing is crucial in the prevention of disease, a healthcare provider should be notified as quickly as possible after a potential exposure.

Prevention

Hepatitis A and B vaccines can protect you for life! The hepatitis A vaccine is given in 2-doses over the span of six months and the hepatitis B vaccine is given in 3-doses over the course of six months; there is even a 2-dose hepatitis B vaccine now available in the U.S.! You can also ask your doctor about getting the combination vaccine for hepatitis A and B together, which will reduce the number of shots you need.

The CDC recommends that people living with chronic hepatitis B also get vaccinated for hepatitis A to protect themselves against another liver infection and potential liver damage. While the hepatitis A vaccine is routinely given to children in the United States, other countries have different vaccine recommendations, so check with your doctor to see if you have been vaccinated. Hepatitis A can also be prevented by good hygiene practices like washing your hands with soap and hot water after using the bathroom or before preparing food, but the best form of prevention is always vaccination!
