launched an oral cholera vaccination (ocv) campaign in two regions: cerca carvajal and petite anse. these regions were chosen because of particularly high attack rates, sanitation infrastructure, and access to healthcare. this vaccination effort was slightly controversial because the who guidelines at the time did not encourage mass vaccination campaigns in areas where outbreaks had already occurred. prior to the 2010 outbreak in haiti, vaccination campaigns were thought to detract from more important prevention measures like water treatment and good hygiene. relative success rates (up to 65% or higher protective effectiveness 5 years after vaccination) in recent vaccination campaigns in haiti and other countries affected by cholera has led to more widespread use of oral cholera vaccine programs and a change in the who guidelines to encourage use of vaccines in addition to other prevention and treatment strategies. un approach at the end of 2016, former un secretary general ban ki moon presented the "new un system approach on cholera in haiti". this two-track approach marked the un's acceptance of responsibility for the introduction of cholera in haiti and demonstrated its commitment to the eradication of the disease in haiti. since the 2016 admission of guilt, there has been increased coordination and goodwill between the government of haiti and un, resulting in great strides towards the elimination of cholera. 2017 was a hallmark year in the elimination of cholera from haiti. the 2017 – 2018 haiti revised humanitarian plan reports, "as of 31 december 2017, 13,682 suspected cholera cases and 150 deaths had been registered in the country in 2017 compared to 41,955 cases and 451 deaths for the same period in 2016, a decrease of 67% in both cases". newly developed rapid response teams are largely to credit for the reduction in disease incidence. the ability for the humanitarian sector to act quickly and bounce back following hurricane matthew in 2016, as well as to maintain the downward trend during the heavy rain season, demonstrates progress in the eradication of cholera in haiti. track 1 track 1 of the new un system approach on cholera in haiti aims to "intensify efforts to respond to and reduce the incidence of cholera in haiti" through three main projects. the first is strengthening and supporting the rapid response framework developed by the haitian government which deploys to communities where cholera is suspected within 48-hours. there are currently 13 government led rapid response teams, and 60 mobile teams of humanitarian actors that support the rapid response teams. the goal of rapid response teams is to cut the transmission of cholera by first setting up a perimeter called a cordon sanitaire and investigating the source of the outbreak at the household level. this investigation is coupled with education and awareness raising on cholera prevention, administering oral prophylaxis and distribution of wash kits. if an outbreak is confirmed, temporary chlorination points are installed on community water sources. people treated for cholera by the rapid response teams are then recruited to community engagement & hygiene awareness (ceha) teams. the ceha teams return to their communities to conduct outreach and sensitization on how to cut transmission and assist the government in monitoring water sources. this rapid response design with the assistance of the ceha teams is responsible for a major decline in disease incidence in the ouest department in 2017. as long as funding continues to support rapid response, a continued decline in disease incidence can be suspected. the second project of track 1 is the continued support of oral cholera vaccination campaigns as a preventative measure. in 2018, the oral cholera vaccine campaign will focus on departments with the highest incidence of disease, particularly artibonite and centre departments. the final aim of track 1 is to "more effectively address… the medium/longer term issues of water, sanitation and health systems". the 2010 earthquake and subsequent cholera outbreak/epidemic exposed to the international community how vulnerable the haitian water, sanitation, and health infrastructure was. cholera and other water-borne diseases will continue to circulate in haiti as long as large sections of their population do not have access to improved water and sanitation facilities. as part of the un's "new way of working" which aims to bridge the development and humanitarian gap, the un will be working with major development actors including the world bank and the international development bank to address infrastructure vulnerabilities that put haiti at risk of protracted crisis. the "new way of working" aims to draw from funding sources on both sides of the spectrum, both development and humanitarian, to work towards the sustainable development goals. no joint funded projects have been reported in haiti yet. track 2 the second track of the new un system approach on cholera in haiti proposes to provide material assistance to individuals and families who were most affected by cholera. the material assistance package is the un's attempt at reparations after accepting responsibility for the introduction of cholera in haiti. the un reports, "nearly 800,000 haitians have been infected by cholera since 2010 and more than 9,000 have died". first, consultations will be conducted with the community to identify what materials will be of greatest impact. 2020 update: january of this year marked the 10-year anniversary of the devastating earthquake in haiti. in addition, to the lives lost in the earthquake thousands of lives have been affected by the introduction of cholera to haiti by un peacekeepers in nepal. it is estimated that over the last ten years 820,000 cases and nearly 10,000 deaths have been reported as of january 18, 2020. we briefly describe an update on the cholera epidemic in haiti since 2016. in 2015, haiti had more reported cases of cholera per population than any other country and in 2016 hurricane matthew added a new urgency to mitigating the suffering in haiti due to cholera. in the same year the un apologized to the haitian people for the epidemic, after scientific studies linked the cholera epidemic to un peacekeepers that were not screened for the disease prior to their arrival in haiti after the earthquake. and pledged to provide 400 million dollars in two years to implement "track 1" and "track 2" aimed at providing water sanitation and improved access to treatment and material assistance to haitians affected by the cholera epidemic respectively. however, to date only 21 million dollars have been raised and 3 million dollars have been utilized. while to date only 5% of the funds for these tracks have been raised ongoing humanitarian efforts by the un, other ngo's, and the haitian government the new cases of cholera have drastically decreased in the last 5 years. a series of studies from 2013 to 2016 proved that the combination of chlorination and cholera vaccination could eliminate cholera in one of the poorest areas in haiti. after hurricane matthew in 2016, the who and other technical partners developed teams to investigate the scale of cholera outbreaks. then in october 2016, the haitian ministry of public health and population requested and received 1 million doses of the oral cholera vaccine, partially funded by gavi, the vaccine alliance. the who and other partners including unicef, international medical corps, the red cross and gavi, the vaccine alliance teams reached over 729,000 people most affected by hurricane matthew. these and ongoing efforts by the haitian government and humanitarian aid have only continued to decrease the number of cholera cases in haiti. in 2018 only 3700 cholera cases and 41 deaths were reported from 90% of the departments in haiti. then in 2019 the un announced that haiti had been cholera free for one year, with the last confirmed case reported to be in the artibonite in january 2019. however, in order to obtain validation that cholera has ended in haiti the country must maintain effective surveillance systems and remain cholera free for two more years.
