Polonium-210 poisoning in London: hypochondriasis and public health.

INTRODUCTION In November 2006, a Russian dissident died from radioactive Polonium-210 (210Po) poisoning in London. Providing reassuring messages during a public health incident may be ineffective for individuals with high health anxiety (hypochondriasis). METHODS Members of the public who called a 24-hour telephone helpline were offered a follow-up call by a health protection specialist for reassurance. A psychiatrist attempted to contact those callers who were unable to be reassured by the health protection specialist. RESULTS Of 872 individuals contacted for reassurance, seven (0.6%) could not be reassured. The psychiatrist contacted four of these individuals. Three had a history of health-related anxiety and two attributed somatic symptoms to 210Po exposure. CONCLUSIONS For individuals with hypochondriasis, reassurance during major public health incidents may be ineffective. Having a psychiatrist available was helpful in managing individuals with excessive health anxiety.
