I am referring to hepatitis A, which is less dangerous than other forms of viral hepatitis, since it does not become chronic and is benign in most cases. Hepatitis A is an infectious disease caused by the virus of the same name, which attacks and damages liver cells. This liver infection is contracted through the fecal-oral route, mainly through contact with other infected people or by ingesting contaminated water and food. About 15-50 days after infection, hepatitis A manifests itself with fever, malaise, jaundice (therefore with a yellowish coloration of the skin), loss of appetite and nausea. As anticipated, this form of hepatitis generally has a benign evolution and, as a rule, heals spontaneously without the liver suffering permanent damage. Unlike hepatitis B and C, it never becomes chronic; furthermore, those who recover from hepatitis A develop permanent immunity that protects them from subsequent infections. The hepatitis A virus (known by the acronym HAV, from Human Hepatitis A Virus) proliferates in the intestine and liver, and is expelled through bile and feces. The virus is therefore present in the excrement of infected people already a few days after infection and continues to be eliminated up to a week after recovery. The peak of contagiousness is recorded approximately 7-10 days before the onset of symptoms, when fecal excretion of the virus is at its highest. Therefore, transmission of hepatitis A occurs mainly through the fecal-oral route, through contact with an infected individual, for example, by putting your hands in your mouth after shaking hands or using cutlery that he has handled without washing your hands after going to the toilet. Transmission of hepatitis A through the consumption of contaminated water or food is also very common. In fact, from feces and sewage fluids, the virus can contaminate groundwater and through them reach various types of food, such as fish products (i.e. fish, molluscs and crustaceans), vegetables, fruit and all derived products. Poor personal hygiene conditions, together with failure to comply with basic hygiene rules when handling food, can therefore favor contagion. Hepatitis A can also be transmitted through oral-anal sexual practices. Furthermore, although quite rare, contagion through blood is possible, which occurs, for example, in the case of transfusions or through the exchange of syringes used for self-administration of drugs. The symptoms of hepatitis A do not appear immediately, but make their debut after a fairly long incubation period, which varies from 15 to 50 days. During this period of time, the disease is still contagious. In particular, the excretion of viruses during the incubation period clearly favors the transmission of the disease, since in this phase the individual is still asymptomatic, therefore unaware of his condition. Only a few weeks after infection, hepatitis A manifests itself with the first symptoms. In the first phase, symptoms appear that can be misleading, making one think of a flu-like illness; in fact, tiredness, nausea, vomiting and loss of appetite, headache, fever and muscle and abdominal pain appear. Later, symptoms and signs suggestive of liver damage appear, such as jaundice, which consists of the yellowish coloration of the skin and the white part of the eye. This yellowing is due to the increased concentration of bilirubin in the blood. In fact, the damaged liver is not able to eliminate this substance, which derives from the demolition of aged or no longer functioning red blood cells.
