Criterion

Criterion weight

Question and answer choices

Severity of disease

0.36

What is the case fatality ratea for the disease in animals and human in the ECOWAS region?

• Case fatality rate in one or both sectors ≥ 15% – 2 points

• Case fatality rate in one or both sectors ≥ 5—< 15% – 1 point

• Case fatality rate in both sectors < 5% – 0 points

Prevention and control capacity

0.19

Is there any effective preventive or therapeutic measure (vaccine or antimicrobial) for humans and/or animals?

• Animals and humans – 2 points

• Animals or humans – –1 point

• Neither – 0 points

Epidemic or pandemic potential

0.18

Has the pathogen caused an epidemic (human or animal) in the ECOWAS region?

• Within the past 5 years – 2 points

• Within the past ≥ 5 and < 10 years – 1 point

• Never or more than 10 years ago – 0 points

Ability to detect

0.16

Is there a One Health surveillance systemb for this disease (investigation, laboratory, or data sharing) in the ECOWAS region?

• For all three sectors – 2 points

• For two sectors – 1 point

• For one sector or none of the sectors – 0 points

Socio-economic and environmental impact

0.12

Is the disease on the OIE list of notifiable diseasesc and is the disease potentially affected by climate change (host range, vector or reservoir)?

• Yes to both – 2 points

• Yes to one – 1 point

• No – 0 points

  1. a If data from the ECOWAS region was not available, global data was used
  2. b If five or more ECOWAS countries had a surveillance system for a disease in a particular sector, the sector was considered to have a surveillance system for that disease
  3. c The OIE list was agreed upon by the Member States as a proxy to measure socio-economic impact
