Childhood Viruses Overview

Measles: Caused by Morbillivirus, highly contagious via respiratory droplets. Symptoms include fever, cough, runny nose, conjunctivitis, and a characteristic maculopapular rash.
Rubella: Caused by Rubella virus, spread through respiratory secretions, can be vertically transmitted to the fetus. Symptoms include a mild rash, swollen lymph nodes, and fever.
Erythema Infectiosum (Fifth Disease): Caused by Parvovirus B19, transmitted via respiratory droplets. Symptoms include a "slapped cheek" rash, lacy rash on extremities, and fever.
Mumps: Caused by Mumps virus, spread via respiratory droplets. Symptoms include swelling of parotid glands, fever, and orchitis.
Varicella (Chickenpox) and Shingles: Caused by Varicella-zoster virus, transmitted via airborne droplets. Chickenpox symptoms include a vesicular rash, fever, and malaise. Shingles is a reactivation of the virus and causes a localized rash.

Key Concepts

Positive Serology indicates past infection or immunity. However, in the case of Varicella zoster virus (VZV), a positive IgG result does not guarantee immunity against reactivation as shingles. This is especially important for older adults and immunocompromised individuals.
Vaccination Importance: Vaccines are essential for preventing childhood viral infections; despite the effectiveness of vaccines, recent outbreaks highlight their ongoing need.

Quiz Questions and Answers

Positive serology indicates a higher risk of developing disease rather than immunity in Varicella zoster.
Fever, coughing, red eyes, and Koplik spots are most likely symptoms of Measles.
Pregnant women are the population most concerned about immunity to rubella.
Oral swab and urine for PCR are the best samples to confirm Mumps infection in an unvaccinated 6-year-old boy.
A 56-year-old man with a positive varicella zoster serology has a 10-20% risk of shingles and can be immunized.
Coxsackie virus detection reports should be checked in an outbreak of hand, foot, and mouth disease.
