Activity: Many people with hepatitis prefer bed rest, though it is not necessary to avoid all physical activity while recovering. Diet: A high-calorie diet is recommended. Many people develop nausea and cannot tolerate food later in the day, so the bulk of intake may be concentrated in the earlier part of the day. In the acute phase of the disease, intravenous feeding may be needed if patients cannot tolerate food and have poor oral intake subsequent to nausea and vomiting. Drugs: People with hepatitis should avoid taking drugs metabolized by the liver. Glucocorticoids are not recommended as a treatment option for acute viral hepatitis and may even cause harm, such as development of chronic hepatitis. Precautions: Universal precautions should be observed. Isolation is usually not needed, except in cases of hepatitis A and E who have fecal incontinence, and  in cases of hepatitis B and C who have uncontrolled bleeding. Hepatitis A
Hepatitis A usually does not progress to a chronic state, and rarely requires hospitalization. Treatment is supportive and includes such measures as providing intravenous (IV) hydration and maintaining adequate nutrition.Rarely, people with the hepatitis A virus can rapidly develop liver failure, termed fulminant hepatic failure, especially the elderly and those who had a pre-existing liver disease, especially hepatitis C. Mortality risk factors include greater age and chronic hepatitis C. In these cases, more aggressive supportive therapy and liver transplant may be necessary. Hepatitis B
Acute
In healthy patients, 95–99% recover with no long-lasting effects, and antiviral treatment is not warranted.
After conducting its investigation, the CDC attributed the source of the outbreak to the use of contaminated raw green onion. The restaurant was purchasing its green onion stock from farms in Mexico at the time. It is believed that the green onions may have been contaminated through the use of contaminated water for crop irrigation, rinsing, or icing or by handling of the vegetables by infected people. Green onion had caused similar outbreaks of hepatitis A in the southern United States prior to this, but not to the same magnitude. The CDC believes that the restaurants use of a large communal bucket for chopped raw green onion allowed non-contaminated plants to be mixed with contaminated ones, increasing the number of vectors of infection and amplifying the outbreak. The restaurant was closed once it was discovered to be the source, and over 9,000 people were given hepatitis A immune globulin because they had either eaten at the restaurant or had been in close contact with someone who had. Special populations
HIV co-infection
Persons infected with HIV have a particularly high burden of HIV-HCV co-infection. In a recent study by the WHO, the likelihood of being infected with hepatitis C virus was six times greater in those who also had HIV. The prevalence of HIV-HCV co-infection worldwide was estimated to be 6.2% representing more than 2.2 million people. Intravenous drug use was an independent risk factor for HCV infection.
