DNA virus

RNA enterovirus

Hepatitis A is classified as an RNA enterovirus, which is crucial for understanding its transmission and replication mechanism. The virus belongs to the Picornaviridae family, characterized primarily by its positive-sense single-stranded RNA genome. This classification highlights that Hepatitis A can replicate quickly and spread efficiently, especially in environments with poor sanitation and hygiene practices.

Knowing that Hepatitis A is an enterovirus is important for dental hygienists, as it can be transmitted via the fecal-oral route, emphasizing the need for stringent infection control procedures and patient education about hygiene practices, particularly in communal settings or during outbreaks. Understanding the viral structure and its transmission pathways aids dental professionals in effectively mitigating the risk of spreading Hepatitis A in clinical environments.
