1. a) Control of Case

   1. 1) Rubella cases shall be isolated and avoid contact with pregnant persons. If a pregnant person is exposed, a blood specimen should be obtained and tested for rubella IgG specific and IgM specific antibodies.
   2. 2) Cases shall isolate themselves and be excluded from school, child care facilities or the workplace for seven days after onset of the rash.

2. b) Control of Contacts

   1. 1) Susceptible contacts shall be excluded from school or the workplace from days seven through 23 following rash onset after last exposure.
   2. 2) Susceptible health care workers exposed to rubella should receive a dose of MMR vaccine. Susceptible exposed health care workers who do not receive a dose of MMR and those that are vaccinated after exposure shall be excluded from direct patient care for 23 days after the last exposure to rubella, as no evidence exists that post-exposure vaccination is effective in preventing rubella infection in persons already infected at the time of vaccination.

3. c) Laboratory Reporting

   Laboratories shall report to the local health authority patients who have a positive result on any laboratory test indicative of and specific for detecting rubella virus infection.
