Development and Implementation of the Ebola Traveler Monitoring Program and Clinical Outcomes of Monitored Travelers during October - May 2015, Minnesota

Feasibility and reliability of telemedicine examinations for respiratory distress in children: A pilot study

Respiratory disorders are a leading cause of acute care visits by children. Data establishing the reliability of telemedicine in evaluating children with respiratory concerns are limited. The overall objective of this pilot study was to evaluate the use of telemedicine to evaluate children with respiratory concerns. We performed a pilot prospective cohort study of children 12 to 71 months old presenting to the emergency department (ED) with lower respiratory tract signs and symptoms. Three examinations were performed simultaneously-one by the ED clinician with the patient, one by a remote ED clinician using telemedicine, and one by the child's parent. We evaluated measures of agreement between (a) the local and remote clinicians, (b) the local clinician and the parent, and (c) the parent and the remote clinician. Twenty-eight patients were enrolled (84 paired examinations). Except for heart rate, all examination findings evaluated (general appearance, capillary refill time, grunting, nasal flaring, shortness of breath, retractions, impression of respiratory distress, respiratory rate, and temperature) had acceptable or excellent agreement between raters. In this pilot study, we found that telemedicine respiratory examinations of young children are feasible and reliable, using readily available platforms and equipment.

Self-reported challenges to border screening of travelers for Ebola by district health workers in northern Ghana: An observational study

BACKGROUND

The 2013-2016 Ebola Virus Disease (EVD) outbreak remains the largest on record, resulting in the highest mortality and widest geographic spread experienced in Africa. Ghana, like many other African nations, began screening travelers at all entry points into the country to enhance disease surveillance and response. This study aimed to assess the challenges of screening travelers for EVD at border entry in northern Ghana.

DESIGN AND METHODS

This was an observational study using epidemiological weekly reports (Oct 2014-Mar 2015) of travelers entering Ghana in the Upper East Region (UER) and qualitative interviews with 12 key informants (7 port health officers and 5 district directors of health) in the UER. We recorded the number of travelers screened, their country of origin, and the number of suspected EVD cases from paper-based weekly epidemiological reports at the border entry. We collected qualitative data using an interview guide with a particular focus on the core and support functions (e.g. detection, reporting, feedback, etc.) of the World Health Organization's Integrated Disease Surveillance and Response system. Quantitative data was analyzed based on travelers screened and disaggregated by the three most affected countries. We used inductive approach to analyze the qualitative data and produced themes on knowledge and challenges of EVD screening.

RESULTS

A total of 41,633 travelers were screened, and only 1 was detained as a suspected case of EVD. This potential case was eventually ruled out via blood test. All but 52 of the screened travelers were from Ghana and its contiguous neighbors, Burkina Faso and Togo. The remaining 52 were from the four countries most affected by EVD (Guinea, Liberia, Sierra Leone, and Mali). Challenges to effective border screening included: inadequate personal protective equipment and supplies, insufficient space or isolation rooms and delays at the border crossings, and too few trained staff. Respondents also cited lack of capacity to confirm cases locally, lack of cooperation by some travelers, language barriers, and multiple entry points along porous borders. Nonetheless, no potential Ebola case identified through border screening was confirmed in Ghana.

CONCLUSION

Screening for Ebola remains sub-optimal at the entry points in northern Ghana due to several systemic and structural factors. Given the likelihood of future infectious disease outbreaks, additional attention and support are required if Ghana is to minimize the risk of travel-related spread of illness.

The Cost and Public Health System Effects of Active Monitoring and Illness Response for Ebola Virus Disease: A Case Evaluation of Georgia

In August 2014, the World Health Organization declared the Ebola virus disease epidemic in West Africa a public health emergency of international concern. After 2 imported cases of the disease were identified in the United States in autumn 2014, the Centers for Disease Control and Prevention recommended that all jurisdictions begin active monitoring of travelers at risk of developing Ebola virus disease for 21 days from the last day of a potential exposure to minimize the risk of disease transmission. Here we describe the infrastructure development, monitoring processes, total planned expenditures, and effects on the public health system in Georgia associated with active monitoring and illness response of all travelers from Ebola-affected West African countries from October 2014 to March 2016. We conducted qualitative interviews with Georgia Department of Public Health (GDPH) staff. We identified state active monitoring and illness response infrastructure investments and monitoring activities and state and federal funds spent in both areas. And, we evaluated whether active monitoring and illness response enhanced Georgia's ability to respond to future infectious disease outbreaks. Developing the infrastructure to support the monitoring and response required investment in information technology, training of public health and medical personnel, increasing laboratory capacity, and securing personal protective equipment. Estimated total expenditures were $8.25 million, with 76% spent on infrastructure and 17% on daily monitoring. The GDPH leveraged internal resources and partnerships to implement active monitoring and illness response. Infrastructure investment increased surveillance capacity, strengthened relationships between the GDPH and medical providers, and led to the creation of infectious disease transport and hospital networks. Active monitoring and illness response increased outbreak preparedness, but it warrants comparison with other possible responses to determine its overall value.

The Check and Report Ebola (CARE+) Program to Monitor Travelers for Ebola After Arrival to the United States, 2014-2016

The 2014-2016 Ebola epidemic in West Africa influenced how public health officials considered migration and emerging infectious diseases. Responding to the public's concerns, the US government introduced enhanced entry screening and post-arrival monitoring by public health authorities to reduce the risk of importation and domestic transmission of Ebola while continuing to allow travel from West Africa. This case study describes a new initiative, the Check and Report Ebola (CARE+) program that engaged travelers arriving to the United States from countries with Ebola outbreaks. The Centers for Disease Control and Prevention employed CARE ambassadors, who quickly communicated with incoming travelers and gave them practical resources to boost their participation in monitoring for Ebola. The program aimed to increase travelers' knowledge of Ebola symptoms and how to seek medical care safely, increase travelers' awareness of monitoring requirements, reduce barriers to monitoring, and increase trust in the US public health system. This program could be adapted for use in future outbreaks that involve the potential importation of disease and require the education and active engagement of travelers to participate in post-arrival monitoring.

Public Health Management of Persons Under Investigation for Ebola Virus Disease in New York City, 2014-2016

During 2014-2016, the largest outbreak of Ebola virus disease (EVD) in history occurred in West Africa. The New York City Department of Health and Mental Hygiene (DOHMH) worked with health care providers to prepare for persons under investigation (PUIs) for EVD in New York City. From July 1, 2014, through December 29, 2015, we classified as a PUI a person with EVD-compatible signs or symptoms and an epidemiologic risk factor within 21 days before illness onset. Of 112 persons who met PUI criteria, 74 (66%) sought medical care and 49 (44%) were hospitalized. The remaining 38 (34%) were isolated at home with daily contact by DOHMH staff members. Thirty-two (29%) PUIs received a diagnosis of malaria. Of 10 PUIs tested, 1 received a diagnosis of EVD. Home isolation minimized unnecessary hospitalization. This case study highlights the importance of developing competency among clinical and public health staff managing persons suspected to be infected with a high-consequence pathogen.
