Introduction
Covid-19 can involve persistence of nonspecific symptoms and sequelae that last weeks to months after initial recovery, but the definition of this situation is lacking. Thus, the aim of our study is to estimate the prevalence, symptoms, and signs extending beyond the acute phase of Covid-19 compared to the general population not infected with the virus and to assess the factors influencing the occurrence of these symptoms in developing countries like Morocco.
Patients and methods
This study recruited 118 healthcare workers who endured the Covid-19 infection and 118 matched controls that had never experienced it. We have defined Long-Covid-19 according to guidance for NICE, and we used a survey made of direct questions and short answers sent to the recruiters via mail to evaluate the demographic parameters, severity and duration of the Covid-19 symptoms, vaccination against SARS CoV-2, and pulmonary involvement, and a series of general symptoms were looked for.
Findings
Our study found that the prevalence of Long-Covid-19 was 47.4%. Compared to the general population, the symptoms with statistical significative results were predominated by asthenia, myalgia, and brain fog. The severity of the pulmonary involvement on chest CT scan was the only risk factor to their occurrence, whereas no effect of the vaccination anti-SARS-CoV-2 was found.
Conclusion
Comparing to the literature, this study showed that nearly half of the patients who have been infected with SARS-CoV-2 will experience a variety of symptoms after the acute phase of this infection, and that it would be a real burden even in the youngest. We also found that vaccination against SARS-Cov-2 has no impact on this prevalence, which is to the best of our knowledge has never been previously studied.
