We used Google Trends (GT) to investigate whether there was a surge in individuals searching for information related to smell loss during the COVID\u201019 epidemic in Italy, Spain, the United Kingdom, the United States, Germany, France, Iran, and The Netherlands.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>GT was used to explore internet activity related to loss of smell in the 8 aforementioned countries.
