SARS-CoV-2 distribution in human body. A—Viremia: SARS-SoV-2 virus dissemination throughout the body via the bloodstream. B—Neurotropism via circulation and/or an upper nasal transcribrial route that enables the COVID-19 to modify the function of the blood–brain barrier or directly reach the brain. C—Virus binding and engaging with the ACE2 receptors. D—SARS-CoV-2 docks on the ACE2 via spike protein (blue); major organs–lungs, heart, kidneys, intestines, brain, and testicles, that express ACE2 receptors and are possible targets of COVID-19 (D, golden spikes) [45].
