Which type of Hepatitis is highly infectious and primarily transmitted through fecal contamination and oral ingestion?

Hepatitis A is characterized as highly infectious and primarily transmits through fecal contamination and oral ingestion. This means that the virus can be spread through consuming food or water that has been contaminated with the stool of an infected person. This method of transmission highlights the significance of sanitation and hygiene practices, particularly in areas where Hepatitis A is more prevalent.

The other types of hepatitis, such as B, C, and D, are mostly transmitted through other means, such as blood or bodily fluids, rather than through the oral-fecal route. Hepatitis B is mainly spread through contact with infectious body fluids, while Hepatitis C is primarily transmitted through blood-to-blood contact. Hepatitis D, on the other hand, occurs only in those infected with Hepatitis B, further complicating its transmission dynamics. Therefore, the distinct method of transmission associated with Hepatitis A underlines its classification as the highly infectious type linked to fecal contamination and oral ingestion.
