Abstract
Clothing of a person in motion electrifies and causes around his body intensive reproduction of particles of air ions, atoms, and air molecules, aerosols (similar in size to particles of coronaviruses), which are non-contact, in moments of discharge from clothing, currents of displacement and transmission (or air flow) are transferred to the environment, similar to the processes of inhalation of electroaerosols or powder. Waveform recorded outbreaks of coronal discharges (CD) - (pulses of more than 25.0 kV/m) the electrostatic field intensity tension (EFI) recorded by the IRI-04M device on human clothing in casual clothing and shoes, and non-contact (0.4-1.2) m of communication of people in the process of movement in the winter road. In the process of human interaction in antistatic clothing and footwear, current emissions (pulses less than 3.0 kV/m), almost not recorded, indicates the absence of outbreaks of CD. The most likely mechanical attachment (the first phase of absorption) to the target cell was shown to be performed by negatively charged (rather than neutral) particles of coronaviruses. The peak of the spread of coronaviruses in the premises occurs in the conditions of the heating period. In the environment, the peak of distribution depends on seasonal conditions of atmospheric electricity - in autumn and spring higher, in winter and summer being 3-5 times lower. Recommendations are given to normalize anti-static conditions in the premises and to monitor the safety of the clothes of the medical worker at the entrance to the danger zone. The method, the self-control tool (the instrument IRI-04M, located on the sternum of the body) and the criterion of safe electrification of the human - a tension of less than 4.5 kV/m, when there is still no reproduction and transfer of coronavirus particles with a diameter of more than 30 nm.
