CODAS, Manuel Esteban; TORRES VILLAGRA, Karem Alejandra  and  BARRIOS GAYOSO, Cesar Adrian. LONG COVID, most frequent symptoms in post-COVID-19 patients, Paraguay, 2021. Rev. virtual Soc. Parag. Med. Int. [online]. 2022, vol.9, n.2, pp.75-83. ISSN 2312-3893.


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.


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


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.


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.


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.
