About

Little is known about the impact of tonsillectomy and/or adenoidectomy on the severity and presentation of respiratory infections, let alone COVID-19. Current knowledge of the role of NALT suggests that its absence may be associated with an increased risk of severe disease.

Assessing the impact of tonsillectomy and adenoidectomy on the risk of adverse evolution in COVID-19 would help to better identify patients at risk of adverse evolution, so that they can be rapidly offered appropriate treatment. It would also provide a better understanding of the pathophysiology of this infection.

Primary objective: to determine whether there is a link between a history of tonsillectomy or adenoidectomy and the risk of severe COVID-19.

Primary endpoint: proportion of patients with a history of tonsillectomy or adenoidectomy among those hospitalized for severe COVID-19.

The results of this study will be compared with a data-driven study of Covid patients without severe disease.
