Introduction:

SARS-CoV-2 infection caused a pandemic with multiple health, social, and economic consequences, including the persistence of symptoms after acute infection, the so-called long COVID. Several studies around the world have reported several persistent symptoms, citing among the most frequent fatigue, dyspnea, anosmia and the onset of neurological pathologies, among others.

Objectives:

To establish the incidence of long COVID, determine the persistence time of symptoms, and identify post-COVID-19 symptoms.

Methods:

A descriptive, observational, cross-sectional study was carried out in the period of March to November, 2021. The sampling was non-probabilistic of consecutive cases through an online survey.

Results:

Out of 1905 responses analyzed, 80% had persistence of symptoms, 31% reported persistence of symptoms after one month, 16% within two months, and 4% up to six months later. Among the most frequent symptoms, these were cited: fatigue 55%, memory problems 29% and anosmia 27% while 76% presented more than one accompanying symptom.

Conclusions:

Up to 80% reported the persistence of symptoms once the acute COVID-19 infection was over, most of them with more than one concomitant symptom, which were maintained over time, more frequently during the first and second month.
