A novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019 in China. The mutated coronavirus spread worldwide, and some patients infected with SARS-CoV-2 developed coronavirus disease 2019 (COVID-19) manifested with upper respiratory infection, pneumonia, or respiratory distress. Since the SARS-CoV-2 pandemic was declared with surging confirmed cases and mortality of COVID-19 worldwide, it has reshaped our way of living and how to manage patients with allergic diseases. The medical staff, including allergy specialists, has been at the forefront of fighting against the SARSCoV-2 pandemic and is struggling to guarantee safety to themselves and their patients. Thanks to vigorous research into the relationship between SARS-CoV-2 and allergic diseases, we have become able to treat allergic patients with the best of evidence to date. The clinician should make a careful decision on each clinical situation with regard to patient characteristics, local and national circumstances as well as the knowledge we have, since it is still limited. We hope further efforts to identify the nature of SARS-CoV-2 and COVID-19 clearer and effective SARS-CoV-2 vaccination will soon remove the grim picture of the worldwide pandemic and bring us back to normal.
