A cluster of five cases of polymyalgia arteritica within a single family suggests an infectious etiology with an incubation period of 5-7 years and a likely genetic predisposition.

Should not yet change practice in polymyalgia arteritica; leaves open infectious etiology with genetic predisposition for prospective validation.
Case Report (n=5)
The clustering of polymyalgia arteritica in a family, including an unrelated spouse, suggests a potential infectious etiology combined with genetic susceptibility.
Kvernebo et al. (1980) conducted a case report in Polymyalgia arteritica (n=5). Infectious agent and genetic disposition was evaluated on Occurrence of polymyalgia arteritica. A cluster of five cases of polymyalgia arteritica within a single family suggests an infectious etiology with an incubation period of 5-7 years and a likely genetic predisposition.
