Health Advisory
January 12, 2016
Dear Parents/Guardians,
We would like to notify the school community that there has been one (1) confirmed case of measles at
Schell Elementary. We are currently reviewing individual exposure status, although anyone at the school
on January 5, 2016 could have had exposure to the case.
Measles is highly contagious and is transmitted primarily from person to person by respiratory droplets
and airborne spread. Patients are contagious from four days before onset of rash to four days after
appearance of rash. Symptoms of measles include rash, fever≥101°F, cough, runny nose, or eye redness.
Any person suspected of having measles should contact their health care provider and stay at home until
four days after rash onset has passed.
Measles contacts, even vaccinated contacts, should monitor themselves for measles symptoms from day 5
after first exposure through day 21 after last exposure (day of exposure is day 0). Contacts should be
instructed to isolate themselves immediately if measles symptoms develop and notify the health
department.
Those with weakened immune systems and children/staff members who are unvaccinated are at higher
risk of complications from measles. Susceptible, unimmunized persons and partially immunized persons
(i.e. persons who had received only one prior dose of MMR) who continue to refuse the recommended
measles vaccination(s) following exposure to measles are asked to stay home from school, child care
settings, and group settings until 21 days after rash onset in the last cases of measles. Their healthcare
providers should be notified as soon as possible that they were exposed to measles.
All staff that cannot provide adequate evidence of immunity should be vaccinated, regardless of exposure
status. A first dose should be given to those who are unvaccinated. Recommend a second MMR to
persons who have previously received only one MMR as long as 28 days have passed since the first dose.
If you experience or have experienced measles symptoms, or if you have questions, please contact your
healthcare provider immediately. Measles is a very contagious airborne disease. If you develop
symptoms and decide you want to be seen at your doctor’s office or at a healthcare facility such as an
emergency department or emergency clinic, PLEASE CALL THEM FIRST and inform them you were
possibly exposed to measles. Please take this letter with you, so you will be properly evaluated upon
arrival. If you have any questions please contact our office at 972-548-5596.
Thank you,
Collin County Health Care Services
