Disease Investigation Branch

Infectious diseases are caused by microorganisms such as bacteria, viruses, parasites and fungi; they may be transmitted directly or indirectly from one individual to another.   The Disease Investigation Branch (DIB), located within the Disease Outbreak Control Division (DOCD), conducts investigation, surveillance, prevention, and control of general communicable diseases of public health importance. DIB staff monitors incoming disease reports for occurrence of unusual or rare diseases, disease clusters, and outbreaks in the community.



Should you have any questions or would like to report an infectious disease, please contact DIB by phone:
