Background: To what extent has hepatitis A virus become widespread among the patients of Benha Fever Hospital and what are the complications it causes? What procedures have been taken to control the level of infection? Inventory of the symptoms that appeared on patients between 2016 and 2019. Aim of the research: To study the prevalence of hepatitis A among Benha Fever Hospital patients, the apparent symptoms, and the complication rate for some cases. Patients and methods: This study was carried out in cooperation between the Hepato-gastroenterology and Infectious Diseases Department, Al-Azhar University, Cairo, and Benha Fever Hospital from January 2016 to December 2019. The study included 3132 patients with HAV infection in Benha Fever Hospital by studying the apparent symptoms and the analytical results and comparing the results and symptoms of the patients and the fates. (Hospital stay and mortality for whole study group, and relation between mortality and year incidence). Results: By the observation of the diagnosis of Hepatitis A virus it's concluded that 97.3% of patients didn't suffer from complications of HAV and about 2.7% of patients Their health deteriorated and they suffered complications classified as follow: 0.8% of patients suffer from encephalopathy, 0.2% suffered sepsis, 0.5% had pancreatitis, 0.9% had gastrointestinal bleeding, 0.2% had acute renal failure, 0.1% had aplastic anemia, 0.1% had seizures.
