Respiratory Diseases

Respiratory diseases are caused by organisms such as viruses or bacteria that affect the respiratory system (e.g., lungs and throat). The organisms can be spread by coughing, sneezing or face-to-face contact.

We provide public health workers with expertise, support and resources for the prevention and control of infectious respiratory diseases.
