Table 2 Summary of chlamydia natural history parameters used in included studies and suggested evidence based parameter values for future transmission dynamic models

From: How robust are the natural history parameters used in chlamydia transmission dynamic models? A systematic review

Parameter Range used in included papers Suggested value
Proportion asymptomatic Male: 25% - 100% To be based on observed treatment seeking rates in the modelled population[24]
  Female: 70% - 95.5%
Duration of infection   
a) Symptomatic Male: 30 – 33 days 30 - 33 days (consensus)
  Female: 30 – 40 days
b) Asymptomatic Male: 180 days – 3 years 497 days[59]
  Female: 180 days – 3 years
Risk of transmission per act 0.0375 – 0.154 male - female 0.095 (IQR 0.06 – 0.167)[60]
  0.0375 – 0.122 female - male
