Risk factors for hospitalization among adults aged >= 65 years with non-typhoidal Salmonella infection linked to backyard poultry contact

Objective We describe the epidemiology of live poultry-associated salmonellosis (LPAS) and investigate potential risk factors associated with hospitalization among adults aged >= 65 years in the United States during 2008-2017. LPAS is a public health concern in the United States, especially among people with increased risk for hospitalization, such as older adults. Sample We analysed data from people aged >= 65 years with non-typhoidal salmonellosis who reported live poultry contact within seven days prior to illness onset. Procedure We used logistic regression to estimate the odds of hospitalization associated with several risk factors including types of live poultry contact exposures. Results LPAS among older adults in this analysis resulted in high hospitalization rates. Salmonella Hadar infection was associated with increased hospitalization. Among older adults with LPAS, 109 individuals of 127 (86%) reported contact with live poultry at their or someone else's residence, and 85 of 105 with available information (81%) reported owning poultry. Conclusions and Clinical Relevance Additional infection prevention information and education targeted at poultry-owning older adults are needed to prevent illness and hospitalization.
