  • Hepatitis A

    Hepatitis A:Hepatitis A is a liver disease caused by the hepatitis A virus. The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the faeces of an infected person. Symptoms :The incubation period of hepatitis A is usually 14–28 days. Symptoms of hepatitis A range from mild to severe, and can include fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, and dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes).

    Causes : Hepatitis A usually get it when you eat or drink something that's got the virus in it. It's the least risky type because it almost always gets better on its own. It doesn't lead to long-term inflammation of your liver. Even so, about 20% of people who get hepatitis A get sick enough that they need to go to the hospital. There's a vaccine that can prevent it.

    Diagnosis:  Hepatitis A is not clinically distinguishable from other types of acute viral hepatitis. Specific diagnosis is made by the detection of HAV-specific IgM and IgG antibodies in the blood. Additional tests include reverse transcriptase polymerase chain reaction (RT-PCR) to detect the hepatitis A virus RNA, but may require specialised laboratory facilities. Treatment:  Therapy is aimed at maintaining comfort and adequate nutritional balance, including replacement of fluids that are lost from vomiting and diarrhoea.

    Statistics: The incidence of hepatitis A is very low in Sweden. It has been shown that the prevalence of antibodies to hepatitis A virus is 6.6% in individuals < 40 years of age and 1% in those < 20 years old. The number of reported cases of hepatitis A infection has declined from 628 in 1985 to ≈ 250 during the last four years. The attack rate per 100 000 inhabitants has thus declined from 7.3 to ≈ 3 during this period. The number of cases in travellers has been stable at ≈ 140 cases per year during the period 1985–1990.
