Treatment of Measles
Measles treatment is primarily supportive care with mandatory vitamin A supplementation for all children, monitoring for complications, and treatment of secondary bacterial infections with antibiotics. 1
Vitamin A Supplementation (Critical Component)
Vitamin A supplementation is essential for all children with clinical measles and significantly reduces mortality:
- Children ≥12 months: 200,000 IU orally on day 1 1
- Children <12 months: 100,000 IU orally on day 1 1
- Complicated measles (pneumonia, otitis, croup, diarrhea with dehydration, or neurological problems): Administer a second dose of vitamin A on day 2 at the same dosage 1
For children with eye symptoms of vitamin A deficiency (xerosis, Bitot's spots, keratomalacia, or corneal ulceration), use an intensive regimen:
- 200,000 IU oral vitamin A on day 1 2
- 200,000 IU oral vitamin A on day 2 2
- 200,000 IU oral vitamin A 1-4 weeks later 2
- Children <12 months receive half doses (100,000 IU) 2
Critical caveat: Undernutrition is NOT a contraindication for measles vaccination—it should be considered a strong indication for vaccination. 2, 1 Similarly, fever, respiratory tract infection, and diarrhea are not contraindications. 2
Management of Complications
Secondary bacterial infections require prompt antibiotic therapy:
- Acute lower respiratory infections: Standard antibiotic treatment 1
- Otitis media: Appropriate antibiotics 1
- Other bacterial superinfections: Treat according to standard protocols 3
Diarrhea management:

Post-Exposure Prophylaxis
For exposed persons with contraindications to vaccination:
- Standard dose: Immune globulin (IG) 0.25 mL/kg body weight (maximum 15 mL) as soon as possible after exposure 1
- Immunocompromised persons: IG 0.5 mL/kg body weight (maximum 15 mL) 1
For susceptible persons without contraindications:
- MMR vaccine may provide protection or modify disease severity if administered within 3 days of exposure 2, 1
Infection Control Measures
Isolation requirements:
- Patients are infectious 4 days before rash onset through 4 days after rash onset 2
- Healthcare workers with measles should be excluded from work until ≥4 days following rash onset 2
- Place suspected measles patients in airborne-infection isolation rooms (negative air-pressure) immediately 2
- If isolation room unavailable, use private room with closed door and patient should wear a mask 2
- All staff entering the room should use N95 respirators regardless of immunity status 2
Diagnostic Confirmation
Laboratory testing should not delay treatment or control measures:
- Collect serum for measles IgM antibody testing during first clinical encounter 1
- If IgM negative within first 72 hours of rash onset, obtain another specimen ≥72 hours after rash onset 2, 1
- Consider molecular characterization from urine or nasopharyngeal specimens 1

Important Clinical Pitfalls
Do not delay treatment: Vitamin A deficiency increases measles severity and mortality; supplementation is critical even in well-nourished populations. 1
No specific antiviral therapy exists: Despite investigation of agents like ribavirin, there is no proven specific antiviral treatment for measles. 5, 4 Treatment remains supportive.
Report immediately: All suspected measles cases must be reported to local or state health departments immediately for outbreak control. 2
Vaccination during outbreaks: Measles immunization programs should be accelerated, not stopped, during outbreaks. 2
