IntroductionCoronavirus disease 2019 (COVID-19) caused by a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported at the end of 2019 in Wuhan, Hubei Province, People’s Republic of China, at a cluster of unusual pneumonia patients. The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020 by World Health Organization. We are receiving patients in our OPD (Out Patient Department) with a new set of health complications having been infected with COVID-19. We planned to collect our data and try to find by various statistical methods, quantify the complications, and assess how we can deal with the new set of complications we are witnessing in this post-acute COVID-19 group of patients.Materials and methodsThe study was conducted by enrolling the patients at OPD/IPD (In Patient Department) by conducting a detailed history and clinical examination, routine investigations, 2D echocardiography (2D Echo), and pulmonary function test (PFT). The study assessed the worsening of symptoms, new onset symptoms, or the symptoms that continued even in the post-COVID-19 status as post-COVID-19 sequelae.ResultsMaximum cases were male and most of them were asymptomatic. The most common post-COVID-19 symptom that persisted was fatigue. 2D Echo and spirometry were done and changes were noticed even in those subjects who were asymptomatic.ConclusionSince significant findings were seen on clinical evaluation accompanied by 2D Echo and spirometry, it is essential to screen all presumed and microbiologically proven cases for long-term follow-up.
