    The study evaluated the association between COVID-19 and subsequent upper respiratory tract infections (URTIs) in adults.

  • 2

    No significant difference in URTI incidence was found following COVID-19, with a hazard ratio of 1.03 (95% CI, 0.74–1.43; P = .87).

  • 3

    Having at least one child under 5 years was linked to a 74% increased risk of URTI (95% CI, 20%–153%; P = .003).

  • 4

    The study included 320 health care workers, with 152 testing positive for SARS-CoV-2 during the follow-up period.

  • 5

    Findings suggest that other factors, rather than COVID-19, may explain the rise in URTI incidence observed in recent months.
