DigiVet Difficulties:
Symptom classification
(type of disease, urgent or not)
Experts at a distance
→ hard to collect good information → different methods to cure diseases

Conclusion: How can we connect the unconnected?
● Develop offline (voice-based) information services
● Close collaboration
with local population ● Better access to
expert knowledge
