Hepatitis is the Greek term for liver inflammation. It is characterised by the destruction of a number of liver cells and the presence of inflammatory cells in the liver tissue.
Hepatitis can be caused by viruses that primarily attack the liver cells, such as hepatitis A and B. Patients with glandular fever, caused by the Epstein-Barr virus, can also suffer from an attack of hepatitis.
The symptoms of acute hepatitis vary considerably from person to person. Some patients have no symptoms at all, and in most cases, children only show mild symptoms.
In the early stages: tiredness, general malaise, slight fever, nausea, poor appetite, changes in taste perception, pressure or pain below the right ribs caused by an enlarged liver, aching muscles and joints, headache, skin rash.
The jaundiced phase: yellowing of sclerae (the whites of the eyes), skin and mucous membranes, dark urine, light-coloured stools, around this time, the other symptoms subside.
The recovery phase: tiredness that can last for weeks.
The symptoms Chronic hepatitis : Many patients have no symptoms. Tiredness, an increased need for sleep, aching muscles and joints. Periodic light pressure or pain below the right ribs – enlarged liver. Jaundice is a very late symptom of chronic hepatitis. It is a sign that the disease has become serious.
Signs and symptoms of hepatitis A
The hepatitis A virus
(HAV) is found in the faeces of someone infected with the virus. It only takes a tiny amount of faeces getting inside another person’s mouth to cause hepatitis A infection. Personal hygiene, such as careful hand washing, can minimise the risk of the virus being passed on. HAV is a common infection in many parts of the world where sanitation and sewage infrastructure is poor. Often people become infected with HAV by eating or drinking contaminated food or water.
Hepatitis A is also classed as a sexually transmitted disease
(STD) because it can be passed on sexually, particularly during activities such as anilingus (rimming). The washing of genital and anal areas before sex, and the use of condoms or dental dams can help to prevent this risk.Hepatitis A can affect all age groups. Once a person is exposed to the virus it takes between 2 and 6 weeks to produce symptoms.
It is possible to experience mild or no symptoms whatsoever, but even if this is the case the person’s faeces will still be infectious to others. Many people who become infected with HAV will have symptoms that include:
A short, mild, flu-like illness; nausea, vomiting and diarrhoea; loss of appetite; weight loss; jaundice (yellow skin and whites of eyes, darker yellow urine and pale faeces); itchy skin; abdominal pain.
The infection usually clears in up to 2 months, but may occasionally recur or persist longer in some people. Once a person has been infected and their body has fought off the virus they are permanently immune.
