Mild antecedent COVID-19 associated with symptom-specific post-acute sequelae

Area of Science:

• Infectious Diseases
• Neurology
• Public Health

Background:

• Long-term sequelae of COVID-19 and their symptom progression are not well understood.
• The impact of COVID-19 severity on the development of long-term health issues requires further investigation.

Purpose of the Study:

• To investigate the association between COVID-19 severity and long-term sequelae.
• To define the symptom courses and prevalence of long COVID symptoms in relation to antecedent infection severity and treatment.

Main Methods:

• An ambidirectional cohort study involving adults with persistent symptoms (≥3 weeks) post-SARS-CoV-2 infection.
• COVID-19 severity categorized as mild (no hospitalization) or severe (hospitalization).
• Symptom data collected via standardized questionnaires; multivariable logistic regression used to analyze associations.

Main Results:

• Mild COVID-19 was linked to increased odds of fatigue, cognitive impairment, headaches, and dizziness compared to severe cases.
• Remdesivir treatment correlated with reduced fatigue and cognitive impairment.
• Symptoms like fatigue and cognitive impairment peaked 3-6 months post-infection and persisted; headaches peaked at 9-12 months.

Conclusions:

• Mild antecedent COVID-19 is associated with prevalent and persistent long-term symptoms.
• Remdesivir treatment may mitigate fatigue and cognitive impairment post-COVID-19.
• Delayed symptom peaks (3-12 months) and lack of improvement highlight the need for preventative strategies.
