Query: A Molecular Communication Perspective on Airborne Pathogen Transmission
  and Reception via Droplets Generated by Coughing and Sneezing   Infectious diseases spread via pathogens such as viruses and bacteria.
Airborne pathogen transmission via droplets is an important mode for infectious
diseases. In this paper, the spreading mechanism of infectious diseases by
airborne pathogen transmission between two humans is modeled with a molecular
communication perspective. An end-to-end system model which considers the
pathogen-laden cough/sneeze droplets as the input and the infection state of
the human as the output is proposed. This model uses the gravity, initial
velocity and buoyancy for the propagation of droplets and a receiver model
which considers the central part of the human face as the reception interface
is proposed. Furthermore, the probability of infection for an uninfected human
is derived by modeling the number of propagating droplets as a random process.
The numerical results reveal that exposure time and sex of the human affect the
probability of infection. In addition, the social distance for a horizontal
cough should be at least 1.7 m and the safe coughing angle of a coughing human
to infect less people should be less than -25$^\circ$.
