This study aims to assess the clinical presentation, radiological patterns and outcome of COVID-19 infection in patients with chronic pulmonary disease.

Inter-relationship between the severity of COVID-19 infection and chronic pulmonary diseases.

The COVID-19 pandemic has led to many difficulties with the diagnosis and routine management of chronic pulmonary diseases such as COPD, Bronchial asthma, ILD and Bronchiectasis as well as raising concerns about the management and outcomes for patients with these diseases who develop COVID-19.

Although there is conflicting evidence on whether patients with chronic respiratory diseases are more susceptible to COVID-19, these patients exhibit a more severe presentation and higher mortality compared with those without chronic respiratory diseases.

Inclusion Criteria:

• Subjects with confirmed diagnosis of COVID-19 infection by:

RT-PCR And Chest Computed tomography and laboratoty investigations. Patients with chronic chest disease including (COPD, bronchial asthma, ILD, bronchiectasis).

Exclusion Criteria:

• Those who are diagnosed with viral pneumonia caused by viruses other than COVID-19.

Those who are not confirmed to be COVID-19 with PCR or by radiological and laboratory investigations.
