Capitolo 24, Problema 8
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.
Guida verificata passo dopo passo1
Step 1: Understand the nature of parvoviruses in humans. The primary human parvovirus is known as B19 virus, which is responsible for certain clinical conditions.
Step 2: Review the clinical manifestations caused by parvovirus B19. One common disease caused by this virus is erythema infectiosum, also known as fifth disease, which typically presents with a characteristic rash.
Step 3: Analyze the severity of parvovirus infections in children. Parvovirus B19 infections in children are generally mild and self-limiting, with low mortality rates.
Step 4: Consider the symptoms related to parvovirus infection, particularly the skin manifestations. The infection often results in a distinctive reddening of the skin, especially on the cheeks, giving a 'slapped cheek' appearance.
Step 5: Based on the above information, identify which statement contradicts established knowledge about parvovirus B19 infections, focusing on the claim about mortality rates in children.

Erythema Infectiosum (Fifth Disease)
Erythema infectiosum is a mild childhood illness caused by parvovirus B19, characterized by a distinctive 'slapped cheek' rash and sometimes a lacy rash on the body. It is generally self-limiting and not associated with high mortality in healthy children.

Mortality and Clinical Severity of Parvovirus Infections in Children
Parvovirus B19 infections in children are usually mild and rarely fatal. High mortality rates are uncommon except in cases with underlying conditions like anemia or immunodeficiency, making statements about high mortality in typical pediatric infections inaccurate.
