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.
