Measles Management
Prevention
Isolation
- Isolation of household or school contacts solely is not effective in preventing transmission of infection; spread of virus occurs before the onset of symptoms
- Isolation of infected individuals should be done for 4 days after the initial appearance of rashes
Measles Vaccine
- May produce a mild, noncommunicable infection
- Available as monovalent or combined w/ other vaccines (eg mumps, rubella); seroconversion rates same for both monovalent & combined vaccines
- Advisory Committee on Immunization Practices (ACIP) recommends the use of measles-mumps-rubella (MMR) vaccine when any of the individual components is indicated
- 1st dose of MMR vaccine is recommended at 12-15 mth, 2nd dose at 4-6 yr of age or <28 days after the 1st dose
- MMRV may be given as the 2nd dose of measles vaccine at age 11-47 mth
- May also be given as 1st measles vaccine for children aged >4-<14 yr, 2nd dose may be given w/in the same age range
Post-exposure Prophylaxis
- May be protected either by Ig immunization or vaccine administration
- Measles vaccine or MMR vaccine is effective if given w/in 72 hr of exposure
- Ig is administered up to 6 days post-exposure
- Indicated in susceptible contacts of measles patients eg infants <12 mth of age, immunocompromised individuals
- For infants 6-11 mth of age, MMR should be used instead of Ig if given w/in 72 hr post-exposure
