Conclusion
There is a good correlation between the search volume of the Baidu index
and the number of outpatient visits. The changing trend of the Baidu
index can reflect the actual demand of patients. The outbreak and
prevalence of COVID-19, as well as the promotion and implementation of
epidemic prevention measures, have had a certain impact on the
occurrence and prevalence of adenoid hypertrophy in children. At
present, it has a restraining effect on the growth and prevalence of the
disease. Daily use of medical masks, social distancing, and attention to
hand hygiene may reduce the incidence of adenoid hypertrophy.
