Definition

Noun: * A severe form of viral hepatitis: "Serum hepatitis" is the common name for hepatitis B, a serious liver infection caused by the hepatitis B virus (HBV). It is characterized by its transmission through exposure to infected blood or bodily fluids.

Usage

• The term "serum hepatitis" is primarily used in a medical or clinical context to describe the disease, its transmission, or its effects.
• It often appears in discussions about public health, virology, and medical history, as it was a common term before the virus was fully identified.
• Example: "The outbreak was traced back to a batch of contaminated blood products, leading to several cases of serum hepatitis."

Examples

• Noun:
  • Before the development of a vaccine, serum hepatitis was a major risk associated with blood transfusions.
  • The doctor explained that the patient's symptoms were consistent with serum hepatitis.
  • Public health campaigns in the 1970s focused on reducing the transmission of serum hepatitis.

Advanced Usage

• The term is sometimes used historically to distinguish hepatitis B (transmitted via blood/serum) from hepatitis A (infectious hepatitis, transmitted via the fecal-oral route).
• In medical literature, it may be used to discuss the pathogenesis of the HBV virus, which has a strong tendency to persist in the blood serum.

Variants and Related Words

• Hepatitis B (n): The modern and more precise term for the disease caused by the hepatitis B virus. This is the preferred term in current medical practice.
  • The hepatitis B vaccine has drastically reduced the incidence of this disease.
• HBV (n): The standard abbreviation for the Hepatitis B Virus itself.
  • The test confirmed an active HBV infection.

Synonyms

• Hepatitis B: The direct and contemporary synonym.
• Type B hepatitis: An alternative clinical designation.

Notes on Meaning

• The definition specifies it is caused by a DNA virus, which differentiates it from other forms of viral hepatitis (like hepatitis A or C, which are caused by RNA viruses).
• The phrase highlights the classic modes of transmission: sexual contact, transfusion of contaminated blood, or ingestion of contaminated fluids. This contrasts with other hepatitis viruses that have different primary transmission routes.

Noun

1. an acute (sometimes fatal) form of viral hepatitis caused by a DNA virus that tends to persist in the blood serum and is transmitted by sexual contact or by transfusion or by ingestion of contaminated blood or other bodily fluids
