However, the S protein of SARS-CoV-2 binds to human ACE2 less strongly than that of SARS-CoV, which coincides with the fact that SARS-CoV-2 causes less infection than SARS-CoV .
Hata hivyo, protini S ya SARS-CoV-2 inaunganisha kwenye human ACE2 kwa njia dhaifu zaidi kuliko SARS-CoV, jambo linaloambatana na ukweli kwamba virusi vya SARS-CoV-2 husabisha hali isiyo mbaya zaidi ya maambukizi kwa wagonjwa vikilinganishwa na SARS-CoV.
