Hepatitis A

Symptoms & causes Diagnosis & treatment Doctors & departments

OverviewHepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function.

You're most likely to get hepatitis A from contaminated food or water or from close contact with a person or object that's infected. Mild cases of hepatitis A don't require treatment. Most people who are infected recover completely with no permanent liver damage.

Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.

SymptomsHepatitis A signs and symptoms typically don't appear until you've had the virus for a few weeks. But not everyone with hepatitis A develops them. If you do, hepatitis signs and symptoms can include:

FatigueSudden nausea and vomitingAbdominal pain or discomfort, especially on the upper right side beneath your lower ribs (by your liver)Clay-colored bowel movementsLoss of appetiteLow-grade feverDark urineJoint painYellowing of the skin and the whites of your eyes (jaundice)Intense itchingThese symptoms may be relatively mild and go away in a few weeks. Sometimes, however, hepatitis A infection results in a severe illness that lasts several months.

When to see a doctorMake an appointment with your doctor if you have signs or symptoms of hepatitis A.

Getting a hepatitis A vaccine or an injection of immunoglobulin (an antibody) within two weeks of exposure to hepatitis A may protect you from infection. Ask your doctor or your local health department about receiving the hepatitis A vaccine if:

You've traveled out of the country recently, particularly to Mexico or South or Central America, or to areas with poor sanitationA restaurant where you recently ate reports a hepatitis A outbreakSomeone close to you, such as a roommate or caregiver, is diagnosed with hepatitis AYou recently had sexual contact with someone who has hepatitis A

CausesHepatitis A is caused by a virus that infects liver cells and causes inflammation. The inflammation can affect how your liver works and cause other signs and symptoms of hepatitis A.

The virus most commonly spreads when you eat or drink something contaminated with fecal matter, even just tiny amounts. It does not spread through sneezing or coughing.

Here are some of the specific ways the hepatitis A virus can spread:

Eating food handled by someone with the virus who doesn't thoroughly wash his or her hands after using the toiletDrinking contaminated waterEating raw shellfish from water polluted with sewageBeing in close contact with a person who's infected — even if that person has no signs or symptomsHaving sex with someone who has the virusRisk factorsYou're at increased risk of hepatitis A if you:

Travel or work in areas of the world where hepatitis A is commonAttend child care or work in a child care centerLive with another person who has hepatitis AAre a man who has sexual contact with other menHave any type of sexual contact with someone who has hepatitis AAre HIV positiveAre experiencing homelessnessHave a clotting-factor disorder, such as hemophiliaUse any type of illegal drugs (not just those that are injected)ComplicationsUnlike other types of viral hepatitis, hepatitis A does not cause long-term liver damage, and it doesn't become chronic.

In rare cases, hepatitis A can cause a sudden loss of liver function, especially in older adults or people with chronic liver diseases. Acute liver failure requires a stay in the hospital for monitoring and treatment. Some people with acute liver failure may need a liver transplant.

PreventionThe hepatitis A vaccine can prevent infection with the virus. The vaccine is typically given in two shots. The first one is followed by a booster shot six months later.

The Centers for Disease Control and Prevention recommends a hepatitis A vaccine for the following people:

All children at age 1, or older children who didn't receive the childhood vaccineAnyone age 1 year or older who is experiencing homelessnessInfants ages 6 to 11 months traveling internationallyFamily and caregivers of adoptees from countries where hepatitis A is commonPeople in direct contact with others who have hepatitis ALaboratory workers who may come in contact with hepatitis AMen who have sex with menPeople who work or travel in parts of the world where hepatitis A is commonPeople who use any type of illicit drugs, not just injected onesPeople with clotting-factor disordersPeople with chronic liver disease, including hepatitis B or hepatitis CAnyone wishing to obtain protection (immunity)If you're concerned about your risk of hepatitis A, ask your doctor if you should be vaccinated.

Follow safety precautions when travelingIf you're traveling to parts of the world where hepatitis A outbreaks occur, take these steps to prevent infection:

Peel and wash all fresh fruits and vegetables yourself.Don't eat raw or undercooked meat and fish.Drink bottled water and use it when brushing your teeth.Avoid all beverages of unknown purity, with or without ice.If bottled water isn't available, boil tap water before drinking it.Practice good hygieneThoroughly wash your hands often, especially after using the toilet or changing a diaper and before preparing food or eating.

Witnesses took to the European-Mediterranean Seismological Centre website to record their experiences.

“Then I paid attention to the motion. It rolled for maybe 30 seconds and the room open doors trembled.”

They said: “Overall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist.

“The predominant vulnerable building types are heavy wood frame and reinforced/confined masonry construction.”

Fukushima was rocked by a devastating 9.0 earthquake in 2011.

A huge tsunami followed, barrelling inland with waves as high as 40 metres.

Three nuclear reactors went into meltdown, with thousands of people permanently evacuated.

More than 15,000 people died, thousands more were injured and billions of pounds worth of damage suffered.
