Infectious Hepatitis Virus, commonly known as hepatitis A virus (HAV), is a small, non-enveloped RNA virus that belongs to the Picornavirus family. It is the causative agent of the highly contagious disease known as hepatitis A. This viral infection primarily affects the liver, leading to inflammation and disruption of its normal functions.
Infectious Hepatitis Virus is typically ingested through contaminated food or water, or by close contact with an infected individual. Once the virus enters the body, it multiplies in the liver cells, resulting in the release of large amounts of virus particles into the bloodstream. As the infection progresses, symptoms begin to manifest, including fatigue, nausea, jaundice (yellowing of the skin and eyes), fever, loss of appetite, and abdominal pain.
Unlike other forms of hepatitis, such as hepatitis B or C, the Infectious Hepatitis Virus does not lead to chronic liver disease or liver cancer. Most individuals infected with HAV recover fully without any long-term complications, although the recovery period may vary. However, in some cases, especially in individuals with pre-existing liver problems or weakened immune systems, the infection can be severe and may even be fatal.
Prevention of Infectious Hepatitis Virus primarily relies on good personal hygiene practices, such as frequent handwashing, proper sanitation, and safe preparation of food. Additionally, vaccination is available and highly effective in preventing HAV infection. The vaccine for Infectious Hepatitis Virus is recommended for individuals at high risk, including travelers to areas with high rates of infection, individuals with chronic liver disease, men who have sex with men, and intravenous drug users.
