Infectious Disease Outbreak Intelligence

Rapid response system for emerging pathogens using taxonomy analysis, target identification, structure prediction, and computational drug repurposing.

KEY PRINCIPLES:

  1. Speed is critical - Optimize for rapid actionable intelligence
  2. Target essential proteins - Focus on conserved, essential viral/bacterial proteins
  3. Leverage existing drugs - Prioritize FDA-approved compounds for repurposing
  4. Structure-guided - Use NvidiaNIM for rapid structure prediction and docking
  5. Evidence-graded - Grade repurposing candidates by evidence strength
  6. Actionable output - Prioritized drug candidates with rationale
  7. English-first queries - Always use English terms in tool calls (pathogen names, protein names, drug names), even if the user writes in another language. Only try original-language terms as a fallback. Respond in the user's language

When to Use

Apply when user asks:

  • "New pathogen detected - what drugs might work?"
  • "Emerging virus [X] - therapeutic options?"
  • "Drug repurposing candidates for [pathogen]"
  • "What do we know about [novel coronavirus/bacteria]?"
  • "Essential targets in [pathogen] for drug development"
  • "Can we repurpose [drug] against [pathogen]?"

Critical Workflow Requirements

1. Report-First Approach (MANDATORY)

  1. Create the report file FIRST:

    • File name: [PATHOGEN]_outbreak_intelligence.md
    • Initialize with section headers
    • Add placeholder: [Analyzing...]

  2. Progressively update as you gather data

  3. Output separate files:

    • [PATHOGEN]_drug_candidates.csv - Ranked repurposing candidates
    • [PATHOGEN]_target_proteins.csv - Druggable targets

2. Citation Requirements (MANDATORY)

### Target: RNA-dependent RNA polymerase (RdRp)
- **UniProt**: P0DTD1 (NSP12)
- **Essentiality**: Required for replication
- **Conservation**: >95% across variants
- **Drug precedent**: Remdesivir targets RdRp

*Source: UniProt via `UniProt_search`, literature review*
