(left) Contribution of uDNA towards R0 for synaptic transmission with varying threshold number of uDNA copies required for productive infection, c. (right) Contribution of uDNA towards R0 for synaptic transmission with varying integration probabilities, p. We assume that viruses integrate independently and number of viruses transmitted follows a Poisson distribution. Default parameters are λ =10000, d=0.01, η=0.25, p=0.5, c=1, ai=0.7, au=0.7.
