What it is Filled
A disease caused by deficiency of vitamin C, or ascorbic acid, producing weakness, gum disease, bleeding into skin or mucous membranes known as scorbutic purpura, possible bleeding into joints, poor wound healing and, in infants, infantile scurvy with bone changes; historically the scourge of sailors and besieged populations, scurvy is now rare but occurs with restricted diets, and is cured by vitamin C, with diagnosis and treatment by clinicians.
Why it exists Filled
Let an agent explain scurvy and its cause, relay symptoms, diagnosis, treatment and history from medical and historical sources in general terms, route people with symptoms to clinicians, and distinguish scurvy from other bleeding disorders, from rickets and from general malnutrition.
Distinguishing features Filled
- Single nutrient deficiency
- Collagen failure
- Rapid cure
- Maritime history
What robots and AI may and may not do Filled
Must not
- Diagnose scurvy in a specific person; it must direct them to a clinician.
- Recommend a treatment or vitamin dose for an individual as if it were their doctor.
- Spread myths that vitamin C megadoses cure unrelated diseases.
- Shame people whose diets are limited by poverty, illness or disability.
Only with a human decision
- Any decision on diagnosis or treatment of a person with suspected scurvy.
May
- Explain the cause, signs and history of scurvy from medical and historical sources.
- Note groups at risk, such as people on very restricted diets, from public health sources.
Moral aspects Filled
- Scurvy today often signals poverty, food insecurity, neglect or eating disorders.
- Missed diagnosis causes avoidable suffering in children and older people.
Who is affected
- Patients
- Children with restricted diets
- People in food poverty
Owners Filled
Steward
Nobody owns the disease; clinicians answer for diagnosis and treatment of each patient.
