    TLDR Long COVID affects about 27% of patients, with higher risk for women, lower education, and certain income levels.
    This study evaluated 699 patients using a telehealth service to assess the prevalence and associated factors of long COVID, finding an incidence rate of 26.8%. Persistent symptoms included cognitive issues, chronic diarrhea, and cough. Factors linked to a higher incidence of long COVID were female sex, lower education levels, a monthly income between $600 and $1,000, supplementary health assistance, anosmia during acute COVID-19, and the need for in-person care. The study underscores the significant impact of long COVID, affecting nearly one-third of participants, and highlights the role of telehealth in managing post-COVID conditions. Despite limitations like its cross-sectional design and lack of vaccination data, the study provides valuable insights into long COVID's long-term complications.
