Clinical and demographic profile of mild COVID-19 disease: The experience of a single center in India Original Article ABSTRACT Over the small period of time COVID-19 has become a global pan- demic and affected hundreds of countries all over the world. The main objective of our study is to report clinical and demographic profile of mild cases of COVID-19 disease. It is a descriptive study of 105 COVID-19 positive patients whose diagnosis was confirmed with polymerase chain reaction (PCR). The clinical, radiological and laboratory data were collected including age, sex, contact history, symptoms, duration of stay and swab conversion rate. The mean age of population was 39.75 years with a male preponderance. The most common symptom noted was sore throat (29.52%) followed by fever (26.67%). The vital and laboratory parameters were normal in all. All patients recovered with no residual symptoms. We used the innovative 40 step test to early identity deterioration. Eight cases were transferred to high dependency unit/intensive care in view of breathlessness & desaturation in oxygen level and recovered completely. We had no deaths. Pneumon 2021, 33(4):187-190.
