All cause viral hepatitis except –
**Core Concept**
Rhinoviruses are primarily known for causing the common cold in humans, but they are not typically associated with hepatitis. This question tests the student's understanding of the different viruses that can cause hepatitis and their characteristic infections.
**Why the Correct Answer is Right**
Rhinoviruses are part of the Picornaviridae family and are primarily respiratory pathogens. They are known to cause a wide range of respiratory illnesses, including the common cold, but they are not commonly associated with hepatitis. Hepatitis is typically caused by viruses such as hepatitis A, B, C, D, and E, which are members of different viral families. Rhinovirus infections are usually self-limiting and do not lead to liver inflammation.
**Why Each Wrong Option is Incorrect**
**Option A:** Measles is a viral infection caused by the measles virus, which can lead to a range of systemic symptoms, including fever, cough, and rash. While measles virus infection can lead to complications such as pneumonia and encephalitis, it is not typically associated with hepatitis.
**Option B:** Epstein-Barr virus (EBV) is a member of the Herpesviridae family and is best known for causing infectious mononucleosis. EBV can also be associated with certain types of cancer, such as Burkitt lymphoma, and has been linked to hepatitis in some cases.
**Option D:** Reovirus is a member of the Reoviridae family and has been associated with a range of clinical conditions, including gastrointestinal and respiratory illnesses. Some reoviruses have been shown to cause hepatitis in animal models, making this a plausible answer.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that while many viruses can cause hepatitis, the clinical presentation and laboratory findings can help differentiate between the various causes. For example, hepatitis A and E are typically self-limiting and resolve without treatment, while hepatitis B and C can lead to chronic liver disease and require antiviral therapy.
**✓ Correct Answer: C. Rhinovirus**
