Which Hepatitis Virus spreads by direct contact?

Question

Accepted Answer

The correct option is (2):
Hepatitis A is a virus that is typically spread by the fecal-oral route. In public health terms, this means the virus is ingested when a person comes into contact with the feces of an infected person, even in microscopic amounts. This method of spread is directly associated with **close person-to-person contact**, often referred to as "direct contact." Transmission commonly occurs within households, among sexual partners, or in crowded settings where hygiene is poor, such as when an infected person does not wash their hands thoroughly before preparing food or after using the restroom. Hepatitis A is highly contagious and the reliance on close personal contact for transmission makes it the correct answer.

The incorrect option is (1):
Hepatitis B is incorrect because its primary routes of transmission are through blood, semen, or other body fluids. It is generally acquired through sexual contact, sharing contaminated needles for injection drug use, or from an infected mother to her newborn during birth. While sexual contact is a form of direct contact, the overall transmission pattern of Hepatitis B is systemic and related to the exchange of bodily fluids, not the fecal-oral, person-to-person spread implied by the term in this context. The virus does not spread through casual contact.

The incorrect option is (3):
Hepatitis C is incorrect as its transmission is overwhelmingly blood-borne. The most common method of spread is through the sharing of needles or other equipment used to inject drugs, which is a blood-to-blood pathway. Transmission through other forms of close or direct contact, such as those related to poor sanitation or food handling, is not a significant or primary route for Hepatitis C. Its infectivity is closely tied to breaches in the skin or mucosal membranes that allow blood transfer.

The incorrect option is (4):
This option is incorrect because Hepatitis A is demonstrably spread by close personal contact, a primary characteristic of its fecal-oral transmission route. Therefore, selecting "None of these" would disregard the established epidemiological facts regarding the high infectivity and contact-based spread of the Hepatitis A virus.
