Perceptions of health communication, water treatment and sanitation in Artibonite Department, Haiti, March-April 2012
Williams HA , Gaines J , Patrick M , Berendes D , Fitter D , Handzel T . PLoS One 2015 10 (11) e0142778 The international response to Haiti's ongoing cholera outbreak has been multifaceted, including health education efforts by community health workers and the distribution of free water treatment products. Artibonite Department was the first region affected by the outbreak. Numerous organizations have been involved in cholera response efforts in Haiti with many focusing on efforts to improve water, sanitation, and hygiene (WASH). Multiple types of water treatment products have been distributed, creating the potential for confusion over correct dosage and water treatment methods. We utilized qualitative methods in Artibonite to determine the population's response to WASH messages, use and acceptability of water treatment products, and water treatment and sanitation knowledge, attitudes and practices at the household level. We conducted eighteen focus group discussions (FGDs): 17 FGDs were held with community members (nine among females, eight among males); one FGD was held with community health workers. Health messages related to WASH were well-retained, with reported improvements in hand-washing. Community health workers were identified as valued sources of health information. Most participants noted a paucity of water-treatment products. Sanitation, specifically the construction of latrines, was the most commonly identified need. Lack of funds was the primary reason given for not constructing a latrine. The construction and maintenance of potable water and sanitation services is needed to ensure a sustainable change. |
CDC’s early response to a novel viral disease, Middle East respiratory syndrome coronavirus (MERS-CoV), September 2012-May 2014
Williams HA , Dunville RL , Gerber SI , Erdman DD , Pesik N , Kuhar D , Mason KA , Haynes L , Rotz L , Pierre JS , Poser S , Bunga S , Pallansch MA , Swerdlow DL . Public Health Rep 2015 130 (4) 307-317 The first ever case of Middle East Respiratory Syndrome Coronavirus (MERSCoV) was reported in September 2012. This report describes the approaches taken by CDC, in collaboration with the World Health Organization (WHO) and other partners, to respond to this novel virus, and outlines the agency responses prior to the first case appearing in the United States in May 2014. During this time, CDC’s response integrated multiple disciplines and was divided into three distinct phases: before, during, and after the initial activation of its Emergency Operations Center. CDC’s response to MERS-CoV required a large effort, deploying at least 353 staff members who worked in the areas of surveillance, laboratory capacity, infection control guidance, and travelers’ health. This response built on CDC’s experience with previous outbreaks of other pathogens and provided useful lessons for future emerging threats. |
Responding to the Syrian crisis: the needs of women and girls
Sami S , Williams HA , Krause S , Onyango MA , Burton A , Tomczyk B . Lancet 2014 383 (9923) 1179-81 Women and girls are disproportionately affected by conflict because of a lack of access to essential services, as learnt from humanitarian crises in recent years.1, 2 Poor access to sexual assault treatment and emergency obstetric care can contribute to negative health outcomes.1 In Syria, women and girls are strongly affected by the recent conflict and, according to the UN Population Fund, about 1·7 million women and girls might need access to reproductive health services.3 Because women often have an essential role in postconflict reconstruction, their basic needs should be met so they can emerge from this ongoing crisis as essential stakeholders in the recovery process. | The Syrian civil war has entered its third year, resulting in 6·8 million people who need humanitarian assistance, with 5·1 million people internally displaced and 79% of refugees living in urban settings (not camps).4, 5 These estimates change daily as the fighting intensifies. Access to internally displaced people for international organisations is becoming more difficult in Syria.6 The poor access to civilians restricts humanitarian assistance and is a violation of international humanitarian law, which could ultimately result in loss of life.7 Numbers of displaced Syrians are expected to continue to rise.8 The Regional Response Plan for Syria,9 released in June, 2013, requests the humanitarian community to respond to this crisis. At present, only 40% of the total funding requested for Syria has been received.4 Inclusion of long-term planning of comprehensive reproductive health services is imperative to reduce risk factors for reproductive-health-associated causes of morbidity and mortality. |
Discourse on malaria elimination: where do forcibly displaced persons fit in these discussions?
Williams HA , Hering H , Spiegel P . Malar J 2013 12 121 BACKGROUND: Individuals forcibly displaced are some of the poorest people in the world, living in areas where infrastructure and services are at a bare minimum. Out of a total of 10,549,686 refugees protected and assisted by the United Nations High Commissioner for Refugees globally, 6,917,496 (65.6%) live in areas where malaria is transmitted. Historically, national malaria control programmes have excluded displaced populations. RESULTS: The current discourse on malaria elimination rarely includes discussion of forcibly displaced persons who reside within malaria-eliminating countries. Of the 100 malaria-endemic countries, 64 are controlling malaria and 36 are in some stage of elimination. Of these, 30 malaria-controlling countries and 13 countries in some phase of elimination host displaced populations of ≥50,000, even though 13 of the 36 (36.1%) malaria-elimination countries host displaced populations of ≥50,000 people. DISCUSSION: Now is the time for the malaria community to incorporate forcibly displaced populations residing within malarious areas into malaria control activities. Beneficiaries, whether they are internally displaced persons or refugees, should be viewed as partners in the delivery of malaria interventions and not simply as recipients. CONCLUSION: Until equitable and sustainable malaria control includes everyone residing in an endemic area, the goal of malaria elimination will not be met. |
Malaria in Kakuma refugee camp, Turkana, Kenya: facilitation of Anopheles arabiensis vector populations by installed water distribution and catchment systems
Nabie Bayoh M , Akhwale W , Ombok M , Sang D , Engoki SC , Koros D , Walker ED , Williams HA , Burke H , Armstrong GL , Cetron MS , Weinberg M , Breiman R , Hamel MJ . Malar J 2011 10 149 BACKGROUND: Malaria is a major health concern for displaced persons occupying refugee camps in sub-Saharan Africa, yet there is little information on the incidence of infection and nature of transmission in these settings. Kakuma Refugee Camp, located in a dry area of north-western Kenya, has hosted ca. 60,000 to 90,000 refugees since 1992, primarily from Sudan and Somalia. The purpose of this study was to investigate malaria prevalence and attack rate and sources of Anopheles vectors in Kakuma refugee camp, in 2005-2006, after a malaria epidemic was observed by staff at camp clinics. METHODS: Malaria prevalence and attack rate was estimated from cases of fever presenting to camp clinics and the hospital in August 2005, using rapid diagnostic tests and microscopy of blood smears. Larval habitats of vectors were sampled and mapped. Houses were sampled for adult vectors using the pyrethrum knockdown spray method, and mapped. Vectors were identified to species level and their infection with Plasmodium falciparum determined. RESULTS: Prevalence of febrile illness with P. falciparum was highest among the 5 to 17 year olds (62.4%) while malaria attack rate was highest among the two to 4 year olds (5.2/1,000/day). Infected individuals were spatially concentrated in three of the 11 residential zones of the camp. The indoor densities of Anopheles arabiensis, the sole malaria vector, were similar during the wet and dry seasons, but were distributed in an aggregated fashion and predominantly in the same zones where malaria attack rates were high. Larval habitats and larval populations were also concentrated in these zones. Larval habitats were man-made pits of water associated with tap-stands installed as the water delivery system to residents with year round availability in the camp. Three percent of A. arabiensis adult females were infected with P. falciparum sporozoites in the rainy season. CONCLUSIONS: Malaria in Kakuma refugee camp was due mainly to infection with P. falciparum and showed a hyperendemic age-prevalence profile, in an area with otherwise low risk of malaria given prevailing climate. Transmission was sustained by A. arabiensis, whose populations were facilitated by installation of man-made water distribution and catchment systems. |
