Rubella In Question Form

Link to CXR Fundamentals Series on EM:RAP

We explore Rubella (German measles or three-day measles), a disease that remains clinically relevant despite being considered nearly eradicated in the US due to vaccination.

• Congenital rubella syndrome can cause severe complications including cataracts, cardiac abnormalities, growth restriction, and hearing loss
• Rubella typically presents with cephalocaudal rash, low-grade fever, and arthralgia
• The disease is less severe than measles but still concerning for pregnant women
• Written documentation of at least one MMR dose is sufficient evidence of immunity
• PCR testing provides the most accurate diagnosis during acute infection
• Isolation period is seven days after rash onset to prevent transmission
• Rubella has a long 17-day incubation period with contagiousness spanning 7 days before and after rash
• Droplet precautions are appropriate for hospitalized patients
• Management of exposed pregnant women involves isolation and post-delivery vaccination
• Global vaccination coverage varies significantly, with lower rates in low-income regions
