Frostlung Virus

Frostlung Virus is a non-human viral disease identified on Planet Sumter, notable for its exclusive impact on domesticated dinosaur populations and its significant economic consequences rather than direct human health effects. The disease is endemic to cold or marginal climates and has not demonstrated any capacity for human transmission.

Infected animals typically present with a persistent dry cough, increasing lethargy, and progressive respiratory impairment. In advanced cases, the virus causes partial freezing and necrosis of lung tissue, leading to sharp chest pain, collapse, and eventual death if untreated. The condition spreads efficiently through close-contact herds, particularly those kept in exposed or poorly sheltered environments.

Frostlung Virus has had a pronounced impact on Sumter’s agricultural sector, where domesticated dinosaurs are central to transport, heavy labour, and food production. Large-scale herd losses disrupted local economies, increased food insecurity, and forced emergency importation of labour substitutes and protein supplies.

The origin of the virus is believed to be natural, likely linked to environmental conditions unique to Sumter’s climate and biosphere. No evidence of deliberate modification or off-world introduction has been identified.

Countermeasures have focused on veterinary quarantine, improved sheltering and thermal regulation of herds, and selective breeding for resistance. While effective in limiting spread, these measures have not eradicated the virus. Frostlung Virus is now treated as a chronic livestock risk and is frequently cited in QHO assessments of non-human disease threats with systemic economic implications.
