INTRODUCTION We aimed to estimate the prevalence and incidence of specific symptoms and predictors of post-acute COVID-19 syndrome using data collected from an anonymous online survey. METHODS We included adult participants with symptoms ≥60 days (D60+), fulfilling the World Health Organization COVID-19 cases definition, and/or hospitalized for COVID-19 at the time of infection (D0). Self-reported symptoms were collected at D0 and D60+. Logistic regression was performed to identify factors associated with self-reported cutaneous signs prevalence and self-reported tachycardia and/ or HBP incidence on D60+. RESULTS From April to June 2020, 956 members of a Twitter long-term COVID-19 community were included in the study population: 81% were women, 81% were aged <50 year, 22% were smokers, and 95% have never been hospitalized. At D60+, the 956 participants reported a broad spectrum of symptoms which were also present at D0+. At D60+, 16% and 39% of participants reported cutaneous signs and tachycardia and/or hypertension, respectively. The incidence of self-reported tachycardia and/or hypertension at D60+ was 12%. Female gender (AOR=2.56; 95% CI: 1.22-6.1) and smoking (AOR=2.34; 95% CI: 1.39-3.92) were associated with prevalence of cutaneous signs at D60+. Smoking (AOR=2.05; 95% CI: 1.2-3.47) was the main correlate of tachycardia and/or HBP incidence at D60+. CONCLUSIONS The incidence of self-reported tachycardia and/or hypertension is not negligible and suggests an interaction between COVID-19 and smoking. Reinforcing symptoms monitoring of people after acute COVID-19, mainly women and smokers, and expanding the promotion of smoking cessation strategies are novel priorities in this COVID-19 era.
