Hepatitis A is an infectious disease of the liver caused by Hepatovirus A (HAV); [7] it is a type of viral hepatitis. [8] Many cases have few or no symptoms, especially in the young. [ 1 ] The time between infection and symptoms, in those who develop them, is two–six weeks. [ 2 ]
People with hepatitis A are advised to rest, stay hydrated and avoid alcohol. A vaccine is available that will prevent HAV infection for up to 10 years. Hepatitis A can be spread through personal contact, consumption of raw sea food, or drinking contaminated water. This occurs primarily in third world countries. Strict personal hygiene and the ...
Hepatitis A and E are mainly spread by contaminated food and water. [3] Hepatitis B is mainly sexually transmitted, but may also be passed from mother to baby during pregnancy or childbirth and spread through infected blood. [3] Hepatitis C is commonly spread through infected blood such as may occur during needle sharing by intravenous drug ...
To make the distinction, abnormal liver function tests and/or ultrasound suggesting liver disease are required, and ideally a liver biopsy. [ 4 ] [ 9 ] The symptoms of hepatic encephalopathy may also arise from other conditions, such as bleeding in the brain and seizures (both of which are more common in chronic liver disease).
This family represents the internal ribosome entry site (IRES) of the hepatitis A virus. [1] HAV IRES is a 450 nucleotide long sequence [2] located in the 735 nt long 5’ UTR (untranslated region) of Hepatitis A viral RNA genome. [1] IRES elements allow cap and end-independent translation of mRNA in the host cell.
Hepatitis A vaccine is a vaccine that prevents hepatitis A. [ 2 ] [ 3 ] It is effective in around 95% of cases and lasts for at least twenty years and possibly a person's entire life. [ 4 ] If given, two doses are recommended beginning after the age of one. [ 2 ]
A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV, COVID-19, and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes.
The 2019 United States Hepatitis A outbreak was an occurrence of several declared outbreaks of the disease, Hepatitis A, in locations in the United States including substantial instances in the states of Kentucky, [2] Mississippi, Florida, and the city of Philadelphia, Pennsylvania, [3] as well as an isolated food-related occurrence in New Jersey.
