% read the percentage of the community infectious/infected)
% Ni = the number of index case (initial infecious individual, Default = 1).
% Ds = is the minimum safe distance below which the probability of being
% infected is Prinf (Measure of how contagious the disease is:
% Lower means more contagious. Default = 0.05).
% Prinf = probability that you will be infected if you are closer than Ds
% to an infectious iindividial (Measure of how precautious people
% are: washing hands, not touching mucus membrane. Default = 0.2).
