COVID-19, the disease caused by the new coronavirus, can cause lung complications such as pneumonia and, in the most severe cases, acute respiratory distress syndrome, or ARDS. Sepsis, another possible complication of COVID-19, can also cause lasting harm to the lungs and other organs
No definite clinical evidence of reinfection based on worsening of symptoms, Lab or radiological parameters or infection in the contacts.
Pulmonary fibrosis can result due to scarring caused by late resolution of COVID-19 related pneumonia. Acute or chronic Cor-pulmonale may also result due to chronic lung disease and thromboembolism.
It is not yet established that patients who are declared recovered from COVID-19 on the basis of two NEGATIVE RT-PCR tests for SARS-CoV-19 had actually recovered due to laboratory error of testing kits or the the positivity indicated a carrier state, as none of these reports indicated any worsening of clinical condition of the patient based on symptoms, CT-scan or other parameters (1). We have seen many patients with COVID-19 who despite making a clinical recovery are often having positive reports based on the RT-PCR results up to 35 days after initial diagnosis (2). There has been talk of viral RNA belong to dead virus (viral litter, debris) as the explanation for positive RNA-based PCR tests, as this test does not establish the presence of live virus.
Important point is that there is a disconnect between positive tests and the clinical condition of the such COVID-19 patients. If you follow up such patients, none of the patients had adverse outcome.

Reinfection after surviving COVID-19 still possible. However, the severity of such infection is not reported.
