Is COVID-19 Associated With an Increased Risk of Subsequent Upper Respiratory Tract Infections in Adults? A Prospective Cohort Study
Clinical Scorecard: Evaluating the Link Between COVID-19 and the Risk of Subsequent Upper Respiratory Tract Infections in Adults: Findings from a Prospective Cohort Study
At a Glance
Category
Detail
Condition
Upper respiratory tract infections (URTIs) following COVID-19
Key Mechanisms
Assessment of whether prior SARS-CoV-2 infection increases susceptibility to subsequent URTIs; consideration of immune system effects and microbiome disruption
Target Population
Adult health care workers in Montreal, Canada
Care Setting
Outpatient cohort study with biweekly symptom monitoring
Key Highlights
No significant association found between prior COVID-19 infection and increased risk of subsequent URTIs in adults (hazard ratio 1.03; 95% CI 0.74–1.43; P = .87).
Having at least one child under 5 years old was associated with a 74% increased risk of URTI (95% CI 20%–153%; P = .003).
Other epidemiological, individual, and social factors may explain the observed surge in URTIs in Autumn 2022 rather than prior COVID-19 infection.
Guideline-Based Recommendations
Diagnosis
Confirm SARS-CoV-2 infection via PCR or antigen testing.
Define URTI cases by new onset of fever, rhinitis, nasal congestion, sore throat, sneezing, coughing, wheezing, or respiratory secretion changes, excluding symptoms within 48 hours post-vaccination.
Management
Monitor URTI symptoms in adults post-COVID-19 infection as per standard clinical practice.
Consider epidemiological and social factors such as household exposure (e.g., young children) in URTI risk assessment.
Monitoring & Follow-up
Implement biweekly symptom surveys for early detection of URTI episodes in high-risk populations such as health care workers.
Adjust follow-up protocols to account for vaccination timing and potential symptom overlap.
Risks
No increased risk of URTI attributable to prior COVID-19 infection identified in adults.
Increased URTI risk associated with household exposure to young children.
Patient & Prescribing Data
Adult health care workers with and without prior COVID-19 infection
No evidence supports altered treatment or prophylaxis for URTIs based solely on prior COVID-19 infection status.
Clinical Best Practices
Maintain routine surveillance for URTI symptoms in adults regardless of COVID-19 history.
Consider household and social exposure factors when evaluating URTI risk.
Educate patients that prior COVID-19 infection does not necessarily increase susceptibility to other URTIs.
Use standardized symptom definitions and exclude symptoms related to recent vaccination when diagnosing URTIs.
