Study Notes

Clinical Course During Chickenpox

Incubation period: 1 to 2 days before rash to when all vesicles dry
Prodromal period: 1 to 3 weeks before rash, includes symptoms like nausea, headache, myalgia, loss of appetite, fever, and malaise
Infectious period: lasts until all vesicles dry or crust
Reactivation period: not applicable to chickenpox

Clinical Course During Measles

Incubation period: 10 days
Prodromal period: may present as fever, URTI (upper respiratory tract infection) catarrhal phase symptoms, conjunctivitis, and Koplik's spots.
Infectious period: highest during late prodromal period
Complications: may involve pneumonia, encephalitis, and otitis media

Chickenpox vs. Measles

Chickenpox:
- Tiny vesicles (blisters)
- Rash on trunk and limbs
- Sequelae of rashes in specific order
- Involves Gl and respiratory symptoms
Measles:
- Koplik's spots
- Disseminated rash
- Rash on face, then trunk, then extremities

Red Flags for Referral (Chickenpox/Measles)

High temperature, pain, and redness around lesions
Reduced urine output, lethargy, and reduced skin turgor
Erythematous rash or ulceration on lower leg/ankles (in elderly)
Bacterial superinfection, possible measles, dehydration, or cellulitis

Lifestyle Advice (Chickenpox/Measles)

Vaccination
Exclusion from school/nursery
Smooth cotton fabrics to minimize skin irritation
Adequate fluid intake
