No: There is some genetic links to susceptibility to copd, so if your dad or mom had early emphysema, you're more likely to have it. Second hand smoking can cause COPD changes in your loved ones as well. However, it's not a communicable disease in and of itself.
Dr. Theodore Cole
Specializes in Family Medicine
No: COPD is not an infection. It is usually due to exposure to inhaled toxins. Some people have a genetic defect resulting in an enzyme lack that also can play a role. But no need to isolate yourself, you're not contagious!
Dr. Cynthia Point
Specializes in Internal Medicine
No: No, it is caused mostly by toxins damaging the lungs, usually cigarette smoke, and sometimes can be caused by asthma, but it may be in those cases, tobacco smoke is involved also.
Dr. Laura Arbogast
Internal Medicine 20 years experience
No: COPD is caused from long term exposure to irritants such as cigarette smoke and rarely from a genetic cause called Alpha antitrypsin-1 deficiency.
Dr. Cecily Kelly
Specializes in Family Medicine
No: Cope is a chronic lung disease.
Dr. Dean Giannone
Internal Medicine 26 years experience
No: COPD is related to smoking, so you can't "catch" COPD from somebody. You can, however, acquire COPD from the damage related to second hand smoke, so a smoker in your home can give you COPD because of the exposure to cigarette smoke, but not because COPD itself is contagious.
Dr. Jeffrey Crespin
Gastroenterology 29 years experience
No: The most common cause of COPD is smoking. A small percentage of patients are also deficient in an enzyme called alpha1antitrypsin and will also develop emphysema.
Dr. Pierre Semrani
Specializes in Family Medicine
No: COPD is a chronic [long standing] state of inflammation of the lungs; it is not an infection; it does increase the risk of getting a lung infection "pneumonia" at which stage the person is contagious.
Dr. Latisha Smith
Wound care 39 years experience
No: Chronic obstructive lung disease, COPD is a condition caused by scarring in the lungs. People with COPD often develop recurring lung and bronchial infections which are , like all infections, contagious. The infection is spread by coughing so good hand washing and covering a cough will limit spread of respiratory infections.
Dr. Jason Bellak
Allergy and Immunology 22 years experience
No: COPD (chronic obstructive pulmonary disease) typically results from years of smoke inhalation and is defined by a chronic cough and airflow obstruction. People with COPD may have exacerbations caused by respiratory infections that may be contagious--but, this is no different from a patient without copd.
Dr. Yoshi Rahm
Family Medicine 14 years experience
No: Chronic obstructive pulmonary disease is a condition that is usually secondary to inhaled toxins (most commonly cigarette smoke) that is not contagious. Best to stay away from inhaled toxins of all sorts, including second hand smoke.
Dr. Mila McManus
Family Medicine 22 years experience
No: COPD typically means emphysema or chronic bronchitis associated with smoking. Emphysema is a progressive disease which is irreversible, but the progression may be slowed if a person stops smoking.
Dr. Theodore Caspe
Family Medicine 41 years experience
No: COPD is not infectious.
Dr. Kenneth Adler
Family Medicine 41 years experience
No: COPD stands for chronic obstructive pulmonary disease. It has 2 common forms - emphysema and chronic bronchitis. The most common cause by far is smoking. Sometimes it can be caused by environmental exposures and uncommonly it can come from genetic factors. COPD is characterized by prolonged or difficult exhalation and when more severe can lead to low oxygen levels in the body. Don't smoke !

Dr. Yoram Padeh
Allergy and Immunology 23 years experience
No: COPD is not contagious. It is commonly caused by long-term damage to the lungs by inhaling toxic chemicals (e.g. Cigarette smoke) over long periods of time. There are some genetic causes as well (i.e. Alpha-1-antitrypsin deficiency), but no known infectious causes.
Dr. Sally Combest
Anesthesiology 30 years experience
No: COPD is not contagious. It is not caused by a bacteria, fungus, or virus. It is most commonly caused by smoking.
Dr. Klaus d Lessnau
Pulmonary Critical Care 37 years experience
Interesting: COPD is a fancy word for smoking induced lung disease. You do not want anybody to start this bad habit. Therefore you could make it contagious if you smoke.
