Rheumatoid arthritis (RA) is one of the most frequent chronic autoimmune pathologies. It's prevalence varies from 0.5 to 1%, with a primary involvement at the joint, generating disability due to deformities secondary to persistent inflammation. Considering the high impact on the quality of life of those who suffer it, added to the high cost of therapeutic interventions, it becomes imperative for health personnel to join forces to promote early diagnosis and recognize potential complications, in order to impact positively on clinical outcomes. Around 50% of patients with RA may have extra-articular involvement, the lung being one of the most affected organs. In times of SARS-CoV-2 pandemic, it's necessary to remember the types of lung involvement in patients with RA and take into account the susceptibility of these patients to infectious conditions that can generate great morbidity and mortality.
