Every Dog Has Its Data:Evaluation of a Technology-Aided Canine Rabies Vaccination Campaign to Implement a Microplanning Approach
Background: Robust dog vaccination coverage is the primary way to eliminate canine rabies. Haiti conducts annual canine mass vaccination campaigns, but still has the most human deaths in the Latin American and Caribbean region. We conducted an evaluation of dog vaccination methods in Haiti to determine if more intensive, data-driven vaccination methods, using smartphones for data reporting and geo-communication, could increase vaccination coverage to a level capable of disrupting rabies virus transmission.Methods: Two cities were designated into âTraditionalâ and âTechnology-aidedâ vaccination areas. Traditional areas utilized historical methods of vaccination staff management, whereas Technology-aided areas used smartphone-supported spatial coordination and management of vaccination teams. Smartphones enabled real time two-way geo-communication between campaign managers and vaccinators. Campaign managers provided geographic instruction to vaccinators by assigning mapped daily vaccination boundaries displayed on phone handsets, whilst vaccinators uploaded spatial data of dogs vaccinated for review by the campaign manager to inform assignment of subsequent vaccination zones. The methods were evaluated for vaccination effort, coverage, and cost.Results: A total of 11,420 dogs were vaccinated during the 14-day campaign. The technology-aided approach achieved 80% estimated vaccination coverage as compared to 44% in traditional areas. Daily vaccination rate was higher in Traditional areas (41.7 vaccinations per team-day) compared to in technology-aided areas (26.8) but resulted in significantly lower vaccination coverages. The cost per dog vaccinated increased exponentially with the associated vaccination coverage, with a cost of 2.51 for 50% coverage, and $3.19 for 70% coverage.Conclusions: Traditional vaccination methods failed to achieve sufficiently high vaccination coverages needed to interrupt sustained rabies virus transmission, whilst the technology-aided approach increased coverage above this critical threshold. Over successive campaigns, this difference is likely to represent the success or failure of the intervention in eliminating the rabies virus. Technology-aided vaccination should be considered in resource limited settings where rabies has not been controlled by Traditional vaccination methods. The use of technology to direct health care workers based on near-real-time spatial data from the field has myriad potential applications in other vaccination and public health initiatives

Establishment of a High Canine Rabies Burden in Haiti through the Implementation of a Novel Surveillance Program [corrected].
The Republic of Haiti is one of only several countries in the Western Hemisphere in which canine rabies is still endemic. Estimation methods have predicted that 130 human deaths occur per year, yet existing surveillance mechanisms have detected few of these rabies cases. Likewise, canine rabies surveillance capacity has had only limited capacity, detecting only two rabid dogs per year, on average. In 2013, Haiti initiated a community-based animal rabies surveillance program comprised of two components: active community bite investigation and passive animal rabies investigation. From January 2013 -December 2014, 778 rabies suspect animals were reported for investigation. Rabies was laboratory-confirmed in 70 animals (9%) and an additional 36 cases were identified based on clinical diagnosis (5%), representing an 18-fold increase in reporting of rabid animals compared to the three years before the program was implemented. Dogs were the most frequent rabid animal (90%). Testing and observation ruled out rabies in 61% of animals investigated. A total of 639 bite victims were reported to the program and an additional 364 bite victims who had not sought medical care were identified during the course of investigations. Only 31% of people with likely rabies exposures had initiated rabies post-exposure prophylaxis prior to the investigation. Rabies is a neglected disease in-part due to a lack of surveillance and understanding about the burden. The surveillance methods employed by this program established a much higher burden of canine rabies in Haiti than previously recognized. The active, community-based bite investigations identified numerous additional rabies exposures and bite victims were referred for appropriate medical care, averting potential human rabies deaths. The use of community-based rabies surveillance programs such as HARSP should be considered in canine rabies endemic countries
The health impact of rabies in Haiti and recent developments on the path toward elimination, 2010â2015
Haiti, a Caribbean country of 10.5 million people, is estimated to have the highest burden of caninemediated
human rabies deaths in the Western Hemisphere, and one of the highest rates of human rabies deaths in the
world. Haiti is also the poorest country in the Western Hemisphere and has numerous economic and health priorities that
compete for rabies-control resources. As a result, primary rabies-control actions, including canine vaccination programs,
surveillance systems for human and animal rabies, and appropriate postbite treatment, have not been fully implemented
at a national scale. After the 2010 earthquake that further hindered the development of public health program infrastructure
and services, the U.S. Centers for Disease Control and Prevention worked with the Ministry of Public Health
and Population and key health development partners (including the Pan-American Health Organization) to provide
technical expertise and funding for general disease surveillance systems, laboratory capacity, and selected disease
control programs; including rabies. In 2011, a cross-ministerial rabies consortium was convened with participation from
multiple international rabies experts to develop a strategy for successful rabies control in Haiti. The consortium focused on
seven pillars: 1) enhancement of laboratory diagnostic capacity, 2) development of comprehensive animal surveillance
system, 3) development of comprehensive human rabies surveillance system, 4) educational outreach, 5) sustainable
human rabies biologics supply, 6) achievement of sustained canine vaccination rates of Âł 70%, and 7) finalization of a
national rabies control strategy. From 2010 until 2015, Haiti has seen improvements in the program infrastructure for
canine rabies control. The greatest improvements were seen in the area of animal rabies surveillance, in support of which
an internationally recognized rabies laboratory was developed thereby leading to an 18-fold increase in the detection of
rabid animals. Canine rabies vaccination practices also improved, from a 2010 level of approximately 12% to a 2015 dog
population coverage level estimated to be 45%. Rabies vaccine coverage is still below the goal of 70%, however, the
positive trend is encouraging. Gaps exist in the capacity to conduct national surveillance for human rabies cases and
access to human rabies vaccine is lacking in many parts of the country. However, control has improved over the past
5 years as a result of the efforts of Haitiâs health and agriculture sectors with assistance from multiple international
organizations. Haiti is well situated to eliminate canine-mediated human rabies deaths in the near future and should serve
as a great example to many developing countries struggling with similar barriers and limitations.http://www.ajtmh.orgam2017Microbiology and Plant Patholog
