Hepatitis B

Hepatitis B is a serious viral infection that affects the liver and can become a chronic condition. It can cause cirrhosis of the liver and liver cancer.

What Are the Symptoms?

People infected with Hepatitis B may not experience any symptoms at all. In some cases, the person will feel sick for a period of days or even weeks. In rare cases, the person can become very ill. Common symptoms include loss of appetite, fatigue, low-grade fever, muscle and joint pain, nausea, vomiting, jaundice (yellowing of the skin) and dark urine.

Where Is It Found?

Hepatitis B is commonly found in Asia, South and Central America and Africa, but does occur worldwide.

How Can You Get It?

Hepatitis B is typically spread by way of improperly screened blood transfusions, contaminated needles, dental and medical equipment, tattoo and body piercing devices, razors and by having unprotected sex with infected partners.

How Can You Prevent It?

Travelers planning on an extended stay or who are planning certain activities should be immunized with the Hepatitis B vaccine. It is best to complete at least 2 of the 3-shot series prior to travel.

Who Should Get Vaccinated?

All travelers visiting areas where Hepatitis B is widespread should be vaccinated against the virus, especially those who place themselves at risk while abroad. This includes engaging in unprotected sex, using intravenous drugs and participating in contact sports.

What To Expect Following Immunization

Most adverse reactions to Hepatitis B are mild and include soreness and redness at the site of injection. These symptoms are usually confined to the first few days.
