The first four coronaviruses are endemic globally and account for 10% to 30% of self-limiting upper respiratory tract infections in immunocompetent individuals.3 SARS-CoV-2 is sensitive to ultraviolet rays and heat, and can be effectively inactivated by lipid solvents including ether (75%), ethanol (60-90%), chlorine-containing disinfectant, peroxyacetic acid, and chloroform except for chlorhexidine.3 The virus has been shown to use the angiotensin-converting enzyme 2 (ACE2) for cell entry similar to the severe acute respiratory syndrome (SARS) coronavirus.6 Here, ACE2 is linked to Recurrent upper respiratory tract infections.
