Due to non-specific acute febrile illness in its early stage including substantial number of asymptomatic cases, there are limitations to define the true incidence and case fatality rate of YF.

*WHO suggests case definitions to survey YF with '''suspected case''' as ''Any person with acute onset of fever, with jaundice appearing within 14 days of onset of the first symptoms''.

*A mathematical estimation using Bayesian model showed probability of asymptomatic '''infection''', '''mild disease''' and '''severe disease''' as '''55%''', '''33%''' and '''12%''', respectively, as well as '''case fatality rate among severe disease''' as '''47%''', but the 11 studies authors collected for the study were highly heterogeneous.
