Pandemic from Novel or Engineered Pathogen
A novel pathogen, whether naturally emergent through zoonotic spillover or deliberately engineered via synthetic biology, causes a pandemic exceeding COVID-19 in severity. Advances in gene synthesis, AI-assisted protein design, and dual-use research lower the barrier to creating dangerous pathogens. The GPMB 2025 report warns that global preparedness remains inadequate despite post-COVID investments, and the WHO emphasizes that the next deadly pathogen could emerge from a cave, farm, or laboratory.

Engineered pandemics pose a far greater existential risk than natural pandemics. Toby Ord estimates engineered pathogen risk at 1-in-30 per century versus 1-in-10000 for natural pandemics.
Broad agreement that synthetic biology dramatically expands the threat space. Natural pandemics, while recurring, have not caused existential outcomes in recorded history. Engineered pathogens could combine transmissibility, lethality, and immune evasion in ways nature has not.
Acknowledges the theoretical risk but notes that the same biotechnology advances enabling engineered pathogens also enable rapid countermeasure development (mRNA vaccines, broad-spectrum antivirals, metagenomic sequencing). Net effect is debated.
Global pandemic preparedness has not materially improved since COVID-19 in the dimensions that matter most: equitable access, rapid response capacity, and international coordination.
GPMB 2025 report explicitly states that despite investments, the world remains vulnerable due to persistent inequities, mistrust, and underinvestment. Pandemic treaty negotiations have stalled repeatedly.
Views post-COVID governance as having further eroded public trust in health institutions, making future compliance with public health measures even less likely. WHO authority is contested by multiple member states.
Indicators
- • Unusual disease clusters with high case fatality ratio detected by WHO surveillance
- • Increasing accessibility of gene synthesis technology with decreasing cost per base pair
- • AI models capable of predicting gain-of-function mutations published openly
- • Breakdown in international biosurveillance cooperation or treaty negotiations
- • Documented lab safety incidents at BSL-3/4 facilities increasing in frequency
- • Decline in routine vaccination coverage creating larger susceptible populations
