No one is safe from COVID-19 but certain groups of people are apparently more susceptible to this deadly disease. Elderly people those with underlying health conditions like diabetes heart disease etc. are said to be at greater risk of getting COVID-19 infection and complications. Now a new research has warned that current smokers and people with chronic obstructive pulmonary disease (COPD) also have an increased risk of severe complications and higher mortality with COVID-19 infection. COPD is a common persistent dysfunction of the lung associated with a limitation in airflow. It is estimated to affect around 251 million people worldwide.
