Hepatitis A - Treatment and Prevention
Hepatitis A is a liver infection US travelers can easily prevent with a vaccine, and WayPax Health can write your prescription online before you leave.
Hepatitis A travel prevention for travelers
Hepatitis A is a liver infection caused by the hepatitis A virus (HAV). It spreads through contaminated food and water, making travelers to many parts of the world especially vulnerable. US travelers are at risk because immunity rates at home are lower than in many high-exposure regions, and the infection can sideline a trip for weeks.
WayPax Health is a full virtual travel clinic. A licensed provider will review your itinerary, recommend the right vaccines and medications, and issue a real prescription, all without you ever setting foot in a clinic.

The most effective way to prevent Hepatitis A is vaccination. Two single-antigen vaccines are available in the United States: Havrix and Vaqta. A combination vaccine called Twinrix protects against both Hepatitis A and Hepatitis B and is a good option for travelers who need both. According to the CDC Yellow Book, travelers can prevent HAV infection through vaccination, immune globulin (IG), food and water precautions, and good hygiene practices.
Ideally, you should get vaccinated at least two weeks before departure. Research published in PubMed notes that current recommendations call for travelers to receive the Hepatitis A vaccine two to four weeks before departure. Even a single dose provides strong short-term protection. A second booster dose, given six to twelve months later, provides long-lasting immunity.
Beyond vaccination, you can lower your risk by drinking bottled or treated water, avoiding raw shellfish, and washing your hands thoroughly before eating. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) recommends choosing bottled water over tap water and washing fruits and vegetables when traveling to countries where Hepatitis A is common. Talk to a travel health provider about the right prevention plan for your specific itinerary.

What is Hepatitis A?
Hepatitis A is an inflammation of the liver caused by the hepatitis A virus (HAV). According to the WHO, the virus spreads mainly when a person eats food or drinks water that has been contaminated with the feces (stool) of an infected person. It is closely linked to poor sanitation, unsafe water, and inadequate hygiene.
Common symptoms include fatigue, nausea, stomach pain, loss of appetite, dark urine, and yellowing of the skin or eyes (called jaundice). Symptoms usually appear two to four weeks after exposure, though the incubation period (the time between infection and feeling sick) can range from 15 to 50 days. The CDC notes that most people recover fully from Hepatitis A, and surviving the infection gives lifelong immunity. However, the illness can be severe, especially in older adults and people with existing liver conditions. A GeoSentinel study published in PMC found that travelers still acquire Hepatitis A even when traveling to destinations considered low-risk, underscoring the importance of vaccination before any international trip.
Where is Hepatitis A a risk?
Hepatitis A occurs worldwide, but the level of risk varies significantly by region. According to the WHO, geographic areas can be grouped into those with high, intermediate, or low levels of HAV infection. Risk is highest in places where access to clean water is limited and sanitation infrastructure is poor.
Sub-Saharan Africa, South Asia, Southeast Asia, Central Asia, the Middle East, and parts of Central and South America are generally considered higher-risk regions. In these areas, the virus circulates more widely in the community, and travelers face greater exposure through local food and water supplies. Parts of Eastern Europe and some areas of the Pacific Islands also carry intermediate risk.
Western Europe, North America, Australia, New Zealand, and Japan have lower rates of community transmission due to stronger sanitation systems. However, even in lower-risk destinations, outbreaks can occur, and unvaccinated travelers remain vulnerable. The WHO notes that epidemics linked to contaminated food or water can spread quickly and affect large numbers of people in a short time. Seasonal patterns are less defined for Hepatitis A than for some other infections, but risk remains present year-round in high-transmission regions.
Treatment: what to do if you get Hepatitis A
There is no specific antiviral medication to treat Hepatitis A. The NIDDK explains that treatment focuses on rest, staying hydrated, and managing symptoms while the body fights off the infection on its own. Most people recover fully within a few weeks, though some cases can last several months.
You should seek medical care promptly if you develop symptoms after traveling, especially jaundice (yellowing of the skin or eyes), severe stomach pain, or persistent vomiting. These can be signs of a more serious case that needs close monitoring. Older adults, people with chronic liver disease, and those with weakened immune systems face a higher risk of severe illness and should seek care right away. Research published in PMC highlights that vaccination before travel remains the best strategy, since there is no self-treatment option once infection occurs.
Frequently asked questions
What are the symptoms of Hepatitis A in travelers?
The most common symptoms are fatigue, nausea, stomach pain, loss of appetite, dark urine, and yellowing of the skin or eyes (jaundice). Symptoms usually start two to four weeks after exposure. Some people, especially young children, may have no symptoms at all, while adults tend to feel quite ill.
How can I prevent Hepatitis A when traveling?
The best protection is the Hepatitis A vaccine, taken before your trip. You should also drink bottled or treated water, avoid raw shellfish, and wash your hands often, especially before eating. These steps together give you strong protection against infection while abroad.
Is there a Hepatitis A vaccine for travel?
Yes. Two vaccines are available in the United States: Havrix and Vaqta. A combination vaccine called Twinrix also protects against Hepatitis B at the same time. A single dose before travel provides good short-term protection, and a booster dose six to twelve months later gives long-lasting immunity. WayPax Health can prescribe and arrange your vaccine entirely online, without a clinic visit.
Can you get Hepatitis A from food or water while abroad?
Yes. Hepatitis A spreads through food and water contaminated with the stool of an infected person. Raw or undercooked shellfish, fresh produce washed in unsafe water, and drinks made with tap water or ice are common sources. Choosing bottled water and eating fully cooked foods helps reduce your risk.
Where is Hepatitis A most common for travelers?
Risk is highest in parts of Sub-Saharan Africa, South and Southeast Asia, Central Asia, the Middle East, and Central and South America. These regions have higher rates of HAV in the community due to limited access to clean water and sanitation. Even travelers visiting lower-risk destinations can be exposed, so vaccination is recommended for most international trips.
How is Hepatitis A treated?
There is no specific medicine to cure Hepatitis A. Treatment means resting, drinking plenty of fluids, and letting your immune system clear the infection. Most people recover fully on their own. If you develop severe symptoms like jaundice or intense stomach pain, see a doctor right away.
Should I get the Hepatitis A vaccine before international travel?
Yes, most travel health experts recommend the Hepatitis A vaccine for anyone traveling internationally, regardless of destination. Even countries with lower overall risk can have localized outbreaks. Getting vaccinated before you leave is the single most effective step you can take. WayPax Health makes it easy to get your vaccine prescription online from a licensed travel health provider, with no clinic visit needed.
