Abstract

Background

Relatively little is known about the clinical course of covid-19 and the differences between the symptoms of covid-19 in acute phase of infection and the symptoms of long covid-19 in people with milder outpatient illnesses.

Objective

To compare clinical characteristics of covid-19 in acute infection with long covid-19 (presence of prolonged symptoms for at least 12 weeks, lasting at least 2 months, after acute covid-19 infection, and that are not explained by an alternative diagnosis).

Methodology

Comparison of secondary data among tow previous observational, longitudinal and prospective studies: 1) patients with post-acute covid-19 syndrome from March 15, 2020 to March 31, 2021; and 2) patients with Long covid-19 from March 15, 2020 to October 31, 2022, in the same population in general medicine.

Results

33 covid-19 in acute phase, with 138 symptoms and 27 Long covid-19 cases with 44 symptoms were included. Respiratory symptoms predominated in both groups. Symptoms in Long covid-19 cases were significantly lower in general symptoms (X2= 5.9539. p= .014), and higher in Circulatory and Genitourinary system (Fisher exact test= 0.05).

Conclusion

Both in Long covid-19 and in covid-19 acute phase respiratory symptoms predominate. But they differ in that the symptoms of long covid-19 are less general than those of covid-19 acute phase, and present more symptoms of almost all organs and systems, those of the Circulatory and Genitourinary system being significant. The symptoms of Long covid-19 vs. acute phase are more debilitating and clinically heterogeneous.
