FIGURE 1:
FIGURE 1:. Schematic representation of the postulated sequence involved in the severe acute respiratory syndrome coronavirus 2 infection outbreak over time among Egyptians. Host and/or viral factors may affect patient/virus interaction. Host factors include ACE2 receptor, and other enzymes priming the entry process, e. g., TMPRSS2 and cathepsin. Viral factors include mutation or other subtypes. When the virus infects others, it may remain covert. Overt infection usually results owing to potency restoration (wild type) due to Darwinian selection force or the emergence of a fourth mutant. *Usually: most of the cases but not all.
