The subgroups of the coronavirus families are α, β, γ, and δ coronavirus (the four general human coronaviruses). Representative coronaviruses consist of NL63 coronavirus (human) and porcine transmissible gastroenteritis from the Alphacoronavirus genus; mouse hepatitis coronavirus (MHV), bovine coronavirus (BCoV), severe acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome coronavirus (MERS-CoV); avian infectious bronchitis virus (IBV); and porcine δ-coronavirus (PdCoV). This work exhibits, δ-coronavirus spikes are fundamentally and evolutionally more similar related to α-coronavirus spikes than to β-coronavirus or γ-coronavirus spikes due to the receptor recognition, membrane fusion phenomenon, and immune evasion behavior.trueCOVID-19 | Delta coronavirus | Spike proteinsReview10.33263/BRIAC125.5797581010.33263/BRIAC125.579758102-s2.0-85119340231WOS:0007442768000055797581012
