Parvovirus B19 in human disease

Area of Science:

• Virology
• Infectious Diseases
• Hematology

Background:

• Parvovirus B19 is the sole known pathogenic parvovirus affecting humans.
• It presents with varied clinical manifestations depending on the host's immune status and underlying conditions.

Purpose of the Study:

• To review the diverse disease spectrum associated with Parvovirus B19 infection.
• To highlight diagnostic approaches and current research directions, including vaccine development.

Main Methods:

• Literature review of Parvovirus B19 associated diseases.
• Summary of diagnostic criteria including bone marrow examination and virologic studies.
• Overview of pathophysiology and ongoing vaccine development efforts.

Main Results:

• In healthy individuals, infection commonly manifests as erythema infectiosum.
• In patients with hemolytic disorders, Parvovirus B19 is a primary cause of transient aplastic crisis.
• Immunosuppressed patients and fetuses are susceptible to persistent infection, chronic anemia, pure red cell aplasia, hydrops fetalis, and congenital anemia.

Conclusions:

• Parvovirus B19 infection presents a broad clinical spectrum, impacting various patient groups differently.
• Accurate diagnosis relies on bone marrow and virologic assessments.
• Further research is crucial for understanding pathophysiology and developing preventative strategies like vaccines.
