A respiratory illness caused by the coronavirus first identified in Wuhan, Hubei Province, China in 2019 which likely originally emerged from an animal source, has spread person-to-person in many locales as well as to other countries around the world and has been identified as a pandemic by the World Health Organization (WHO). Symptoms include mild to severe respiratory illness with fever, cough and difficulty breathing. Those most at risk from the virus are older adults and people with pre-existing health conditions.
Any of a variety of disorders of the lungs, pleural cavity, bronchial tubes, trachea, upper respiratory tract or the associated nerves and muscles that are responsible for breathing. Included are obstructive pulmonary diseases such as emphysema and asthma that involve narrowing or blockage of the airways which carry oxygen and other gases into and out of the lungs; restrictive lung diseases such as sarcoidosis and asbestosis that result in incomplete lung expansion and a reduction in the ability of the lungs to take up oxygen and release carbon dioxide; upper and lower respiratory tract infections; benign and malignant tumors affecting the lungs and associated tissue; and pulmonary vascular diseases such as pulmonary hypertension or pulmonary edema that affect pulmonary circulation.
