Bridger Lam · Answer 1

Total number of infected people = 4367 + 768 = 5135

Chance of infection (Whole population) = 3187463 / 5135 = 1 in every 621 people

Prevalence Rate per 100,000 = 0.02 % (According to parallel ratio statistics)

Incidence chances per 100,000 = ~ 20 people ... or ...1 in every 5000 individuals
