Which of the following statements is false?
a. B19 virus is the primary parvovirus of humans.
b. Erythema infectiosum is caused by a parvovirus.
c. In children, parvovirus infections are accompanied by a high mortality rate.
d. Parvovirus infection in humans results in infectious reddening of the skin.

Verified step by step guidance

1. Identify the characteristics and effects of B19 virus, which is a type of parvovirus that primarily infects humans.
2. Understand what Erythema infectiosum is, including its causes and symptoms, and verify if it is indeed caused by a parvovirus.
3. Research the typical outcomes of parvovirus infections in children, focusing on the severity and mortality rates associated with these infections.
4. Examine the symptoms of parvovirus infections in humans, particularly looking for information about skin manifestations such as infectious reddening.
5. Compare the information gathered in the previous steps to each statement provided in the question to determine which statement is false based on factual inaccuracies.

Key Concepts

Parvovirus Overview

Parvoviruses are small, single-stranded DNA viruses that primarily infect animals, but B19 is the only parvovirus known to infect humans. It is associated with various diseases, including fifth disease, which is characterized by a distinctive rash. Understanding the nature of parvoviruses is crucial for identifying their effects on human health.

Erythema Infectiosum

Erythema infectiosum, commonly known as fifth disease, is caused by the B19 parvovirus and typically presents with a 'slapped cheek' rash in children. While it can cause mild symptoms, it is generally not associated with high mortality rates, especially in healthy individuals. Recognizing this condition helps differentiate it from more severe viral infections.

Parvovirus Infection in Children

Infections caused by parvovirus B19 in children usually result in mild symptoms, including fever and rash, and are rarely associated with high mortality rates. Most children recover without complications, making it important to understand the typical clinical outcomes of parvovirus infections to accurately assess the statements regarding their severity.
