Analysis of foodborne disease surveillance of geriatrics from 2018 to 2022 in China’s Mainland

ObjectiveTo provide scientific basis for the prevention and control of foodborne diseases among the geriatrics in China’s Mainland， the epidemiological characteristics of foodborne diseases was understood.MethodsInformation on acute gastroenteritis cases aged ≥65 years in China’s Foodborne Disease Case Surveillance System from 2018 to 2022 was collected and analyzed.ResultsThe overall prevelance of foodborne disease monitoring pathogens among the geriatrics in China was 9.15% （7 218/78 904， 95%CI： 8.95%， 9.35%， with Salmonella spp. being the highest （4.90%， 3 860/78 699， 95%CI： 4.75%， 5.06%）， Norovirus （2.07%， 1 517/73 173， 95%CI： 1.97%， 2.18%）， Diarrheogenic E. coli （1.39%， 1 015/72 763， 95%CI： 1.31%， 1.48%）， Vibrio parahaemolyticus （1.00%， 782/78 386， 95%CI： 0.93%， 1.07%） and Shigella spp. （0.19%， 147/78 611， 95%CI： 0.16%， 0.22%）. The prevelance of Salmonella spp. in male elderly was higher than that in female， while the prevelance of Vibrio parahaemolyticus in female was higher than that in male. The highe
