Influenza, which is commonly called flu, can be serious for a patient with an NTM infection. Speak with your doctor to be certain you understand the difference between the "flu" and a cold. For patients with chronic lung disease, an annual flu shot or vaccine and a periodic (once every five years) pneumovax or vaccine against pneumonia is generally advisable.
Try to avoid contact with people who have colds or the flu, particularly sharing drinking glasses or utensils.
Wash your hands thoroughly with soap and water frequently. Always wash your hands after using the bathroom, contact with other people, and before and after meals and food preparation.
