Delayed Symptoms in Patients Recovered from COVID-19

Area of Science:

• Infectious Diseases
• Pulmonology
• Public Health

Background:

• COVID-19 (Coronavirus Disease 2019) is a novel infectious disease with evolving understanding of its long-term effects.
• Limited data exists on the frequency and nature of delayed symptoms following acute COVID-19 infection.

Purpose of the Study:

• To assess the prevalence of delayed symptoms in patients previously hospitalized with COVID-19.
• To identify the most common persistent symptoms six weeks after hospital discharge.

Main Methods:

• A follow-up cross-sectional study involving 200 patients discharged from a referral hospital in Tehran, Iran.
• Patients were assessed for delayed symptoms six weeks post-discharge, with data collected between February and April 2020.

Main Results:

• Forty-two percent of patients were symptom-free six weeks after discharge; none required hospital readmission.
• The most frequent delayed symptoms were fatigue (19.5%), dyspnea (18.5%), and weakness (18%).
• Other reported delayed symptoms included anxiety and activity intolerance.

Conclusions:

• Fatigue, dyspnea, weakness, anxiety, and activity intolerance are common delayed symptoms post-COVID-19.
• While many patients recover fully, a significant portion experiences mild to moderate persistent symptoms.
• The study highlights the need for continued monitoring and potential rehabilitation programs for COVID-19 survivors.
