Communicable Diseases and Immunization Manual

Guidelines for schools and day nurseries

The purpose of this guide is to provide simple guidelines for reporting and exclusion of infectious diseases, head lice, immunization requirements and environmental cleaning. This information includes signs & symptoms, transmission, contagious period, what needs to be done along with exclusion and reporting guidelines for common childhood communicable diseases.

Cases of specific communicable diseases must be reported to the Health Unit according to the Health Protection and Promotion Act, 1990, c. H.7, s 28, as amended 2014 as follows:

“The principal of a school, who is of the opinion that a pupil in the school has or may have a communicable disease shall, as soon as possible after forming the opinion, report thereon to the Medical Officer of the Health Unit in which the school is located.”

All Diseases of Public Health Significance MUST be reported to the health unit. The health unit will require the name of the child(ren), date of birth, address, home telephone number, name of parent/guardian and their telephone number at work if available.

In order for the health unit to follow-up appropriately with contacts of communicable diseases, you may be requested to provide the most recent list for the class of the infected child(ren). This list must include name, date of birth, address, home telephone number, name of parent/guardian and their work telephone number if available.

Diagnosis should be made by a physician or nurse practitioner. Any child who is too ill to participate fully in regular activities should stay home from school or daycare.

Reporting absenteeism

In order to be pro-active in preventing the spread of communicable diseases, we ask that you contact the Infectious Disease Nurse at the Porcupine Health Unit if the absenteeism rate in your facility increases by 10% or more due to illness.

Pregnant employees and parents

Pregnant employees or parents who are concerned about the effects of any communicable/infectious disease on the unborn child should contact their healthcare provider.

Reporting to public health

Telephone or fax the health unit office to report communicable/infectious diseases in your school or day care. 

Tel: 705-267-1181; Toll-free: 1-800-461-1818; Fax: 705-360-7328
