BACKGROUND: On 20 September 2022, the Ugandan Ministry of Health declared an outbreak of Ebola disease caused by Sudan ebolavirus. METHODS: From 6 October 2022 to 10 January 2023, Centers for Disease Control and Prevention (CDC) staff conducted public health assessments at five US ports of entry for travellers identified as having been in Uganda in the past 21 days. CDC also recommended that state, local and territorial health departments ('health departments') conduct post-arrival monitoring of these travellers. CDC provided traveller contact information, daily to 58 health departments, and collected health department data regarding monitoring outcomes. RESULTS: Among 11 583 travellers screened, 132 (1%) required additional assessment due to potential exposures or symptoms of concern. Fifty-three (91%) health departments reported receiving traveller data from CDC for 10 114 (87%) travellers, of whom 8499 (84%) were contacted for monitoring, 1547 (15%) could not be contacted and 68 (1%) had no reported outcomes. No travellers with high-risk exposures or Ebola disease were identified. CONCLUSION: Entry risk assessment and post-arrival monitoring of travellers are resource-intensive activities that had low demonstrated yield during this and previous outbreaks. The efficiency of future responses could be improved by incorporating an assessment of risk of importation of disease, accounting for individual travellers' potential for exposure, and expanded use of methods that reduce burden to federal agencies, health departments, and travellers.

OBJECTIVES: Information on knowledge of public health professionals about health aspects of the human-animal interface, referred to as One Health, is limited. The objective of this study was to identify factors associated with animal welfare attitudes, practices, and One Health awareness among US Public Health Service (USPHS) officers to assess preparedness for public health response. METHODS: USPHS officers participated in an online, self-administered survey from February 15 through March 2, 2018. A total of 1133 of 6474 (17.5%) USPHS officers responded. We collected information on officers' demographic characteristics, animal welfare attitudes and practices, volunteer and work exposure to animals, and One Health knowledge. We compared (1) One Health knowledge and animal work exposure (deployment, regular assignment, or none) and (2) animal welfare importance and animal work exposure. To adjust for demographic characteristics associated with One Health knowledge, we used multivariable logistic regression. RESULTS: One-third of nonveterinary officers reported encountering animals during deployment, and 65% reported that animal welfare was very or extremely important. We found no difference in One Health knowledge between nonveterinary officers who participated in deployments involving animals and nonveterinary officers who had no work exposure to animals (adjusted odds ratio [aOR] = 1.11; 95% CI, 0.71-1.75). Nonveterinary officers who participated in animal-related public health activities during regular assignment were more likely to have One Health knowledge than nonveterinary officers who had no work exposure to animals (aOR = 7.88; 95% CI, 5.36-11.59). CONCLUSIONS: One Health knowledge and awareness should be further explored in the current US public health workforce to identify training needs for emergency preparedness and other collaborative opportunities.
