Causes of Hepatitis A
Triggering hepatitis A is the very contagious HAV virus that is generally ingested by eating food contaminated with infected faeces or by contact with people who have touched contaminated food or objects. The foods most at risk of contamination are fruit, vegetables, seafood, ice and water. It is also contracted having sex with infected people.

Symptoms of hepatitis A
The symptoms of hepatitis A occur several weeks after the infection and the most common are: fatigue, nausea, vomiting, abdominal pain near the liver, lack of appetite, mild fever, dysentery, dark colored urine, muscle and joint pains, itchy, yellowish complexion. If you have these symptoms, you should contact your doctor and do blood tests to check for the virus.

Hepatitis A, the cure
Hepatitis A generally heals on its own, without the need for special treatments and without permanent liver damage, sometimes within a few weeks, other times it takes months. Those who contract the virus are advised to rest, have a correct diet and continue hydration. Medicines, foods and beverages that strain the liver should be avoided. Fortunately, once healed, you are no longer at risk as antibodies to the virus have been produced.

Careful personal hygiene is very useful to prevent infection, in particular you should carefully wash your hands after being in the bathroom, avoiding contact with infected people or at risk of infection, be careful about what you eat and drink in potentially risky situations , remembering that the virus is neutralized by cooking the infected foods, but not freezing them.

Those who have contracted the virus so as not to infect others must refrain from sexual intercourse, wash their hands thoroughly after being in the bathroom, and do not touch food intended for other people.

People at risk, such as those who are in contact with those who contract the virus (for example, medical personnel) or are exposed to contaminated food and drink (think of trips to some countries where hygienic conditions are precarious) are good ask your doctor and ask to be vaccinated. The vaccine foresees the administration of 2 doses, with the first dose of vaccine (active after 2-3 weeks) it is protected for about a year, with the second one (to be taken after approximately 12-18 months from the first) for about 10 years . The vaccine is part of the normal prophylaxis for those who have to travel to countries and geographical areas where the risk of infection is high.
