Communicable disease service

Communicable diseases are illnesses caused by microorganisms, such as viruses, bacteria, and parasites, that can spread directly or indirectly from a source of infection to others.

Transmission varies depending on the disease. They may spread through the air, respiratory droplets, physical contact, contaminated food or water, blood and body fluids, or insects. Pulmonary tuberculosis spreads through the air, while influenza spreads mainly through respiratory droplets.

Contact a healthcare provider to assess the exposure and determine whether testing or preventive measures are needed. Follow the instructions provided. Do not wait for symptoms to appear before seeking advice, especially if you have been in contact with someone who has tuberculosis.

These include pulmonary tuberculosis, human immunodeficiency virus (HIV) infection, viral hepatitis, influenza, and other communicable diseases.

Patients reported by a government or private healthcare facility as having a communicable disease, subject to the service eligibility criteria.

Yes. In accordance with the service procedures, follow-up begins after a notification is received from a government or private healthcare facility.

No. The need for isolation depends on the disease, its transmissibility, and the patient’s condition. The physician determines whether isolation is necessary, as well as its location and duration, based on the assessment and approved procedures.

Some contacts may require testing or preventive measures, depending on the disease and the nature of the exposure. The healthcare team determines this following an assessment. For example, household or workplace contacts of patients with tuberculosis may need screening.
