Table 2 Score of Integrated Disease Surveillance and Response adequacy (SIA), defined for the present study including: dimensions, items and codes

From: The score of integrated disease surveillance and response adequacy (SIA): a pragmatic score for comparing weekly reported diseases based on a systematic review

Dimension Item Code #
Form & perceived severity of illness* Incubation period 0 = > 14 days; 1 = 7–14 days; 2 = <  7 days
Onset of disease 0 = Mild; 2 = Severe with symptoms
Symptoms in the acute phase 0 = Mild; 2 = Severe
Contagiousness 0 = Low; 1 = Moderate;
2 = High
Death rate (%) without Treatment 0 = <  5; 1 = 6–19; 2 = > = 20
Etiological concept & disease type** Disease Local Name 0 = Without; 1 = Changing according localities;
2 = Shared by localities
Differential diagnosis with other diseases** Number of epidemics reported each year during the last five years 0 = Less than 2; 1 = 2 to 4;
2 = 5
PPV*** 0 = <  20%; 1 = 20–50%;
2 = > = 50%
Spatial distribution of disease** Proportion of health zones affected by epidemics of each of the 15 diseases (%). 0 = less than 20%;
1 = more than 20%
Integration of the disease into a national or global strategy** Internationally funded research 0 = Without; 1 = With
National or International eradication programs 0 = Not; 1 = yes
Response Characteristic* Timely Response 0 = delayed response;
1 = Immediate
  1. PPV = Positive predictive value
  2. a # = Value Numbers
  3. b * = Criteria intrinsically related to pathology
  4. c ** = Criteria changing between countries and over time
