The study revealed that the level of infectivity was much higher in the cells that bordered nasal passages than in the cells in the throat, bronch and lungs. Scientists believe that this was the case because they have discovered that the surface receptor that the virus uses as an infecting cell lane, called ACE2, was more widespread in the cells of the nasal passages than in the cells found in lower parts from the respiratory tract.

Additional results confirmed that in several died as a result of a serious lung infection caused by coronavirus, the infection appeared to be originated from the nasal respiratory tract.
