Fig. 2 — : Estimation of the contribution of non-symptomatic cases to overall transmission of 15 key pathogens. A) the relative infectiousness of infectious cases without symptoms compared to the proportion of infectious cases that have no symptoms; B) the contribution of non-symptomatic cases and symptomatic cases to transmission. *Non-symptomatic/symptomatic case parameters are in absence of treatment where this data is available (exception includes HIV). **Ebola - recent studies find that non-symptomatic Ebola may pose a risk of sustaining transmission. ***Monkeypox - not enough data to calculate contribution to transmission. **** Dengue - some lab studies show relative infectiousness of pre-symptomatics may be higher than symptomatic cases. *****Raw data in appendix. Point values shown for clarity.
