Reliability assessment: What is the intra- and inter-rater reliability of current qualitative F and novel quantitative hygiene metrics across study contexts?
Validity assessment: What is the validity of each metric of interest (i.e., quantitative hygiene and qualitative F metrics) with regard to recent personal hygiene practices and trachoma outcomes?
Utility assessment: What is the utility of each metric (i.e., qualitative and quantitative)?
Risk factor assessment: Do proxy facial and hand hygiene outcomes, as measured by the novel quantitative hygiene metric, represent risk factors of incident C. trachomatis infection?"

Evaluating the adoption of COVID-19 prevention measures during mass drug administration in Anambra State, Nigeria

Are NTD programs in Anambra State, Nigeria, adopting and implementing prevention measures for COVID-19 in their drug delivery activities? What adaptations are required by staff and volunteers to adopt these measures? What are the barriers to doing so? What are the incremental costs associated with conducting MDA during a global pandemic?

Xenomonitoring of black flies to confirm serologic threshold for onchocerciasis elimination mapping

Evaluation of community directed vector control on transmission of Onchocerca volvulus in a Loa loa co-endemic region

This study will pilot the Slash and Clear methodology in an oncho-Loa loa co-endemic setting. Previous pilots in Uganda and Nigeria have demonstrated that this simple strategy of removing breeding sites can result in significant black fly reductions that last for several months. This study will provide important data on the impact of Slash and Clear on black fly biting, and consequently its impact on oncho elimination. Two intervention and one control community will be compared for two years, with repeated measurements being taken of biting rates.

Utility of screening easy to access population sub groups as a surveillance tool in monitoring interruption of LF transmission

The question of how to conduct post-elimination surveillance is a high priority for the NTD community, given that most NTD programs scale back or shut down completely once elimination as a public health problem is achieved. Few solutions exist and this proposal provides an interesting and useful case study for surveillance moving forward. The study team plans to target 1708 pregnant women as a proxy for measuring LF resurgence in a post-elimination context. As a comparison group, they plan to conduct a prevalence survey of 427 households (1708 participants) in the same community to compare LF prevalence found in each methodology. Each participant at the health facility’s residence will be geo-referenced to understand the coverage area. They also plan to conduct interviews with patients and health workers, a time-motion study, and a cost analysis to assess the additional burden on health care workers and the health system. The study will occur in 14 facilities in one district of Malawi where LF was highly endemic prior to the launch of the program.

Community participatory action research to increase MDA coverage in hard-to-reach urban populations

Urban dwellers have frequently been included as "hard to reach" when examining MDA coverage and uptake. Poor coverage in urban settings is a key factor that prevents programs in some settings from achieving success. This research study proposes a community-based participatory action research (CBPAR) strategy to better understand the reasons why this population isn’t reached and/or their decision not to participate in onchocerciasis and lymphatic filariasis MDAs. The results will help identify last mile strategies for urban populations and will generate a technical toolkit for how to conduct rapid participatory research in areas that require novel outreach methods amongst hard-to-reach populations. This form of social science methodology has not been used frequently within the NTD community and this proposal offers an opportunity to build the evidence base for these methods within the context of hard to reach populations.

The researchers plan to conduct a number of activities in order to determine the effectiveness of the participatory approach in targeting urban populations as compared to the standard mobilization and delivery approach.

  1. Rapid ethnographic interviews, a new technique aimed at rapidly collecting and analyzing qualitative data, to gather community feedback regarding barriers in accessing treatment
  2. An intervention development workshop with community leaders, health workers, researchers, and the ministry of health
  3. Deliver the newly designed strategy in Za-Kpota district and compare coverage in urban settings to Ouinhi district
  4. Finalize a rapid participatory approach toolkit and conduct a time-motion study of the approach to improve the business case to the MoH for uptake 5. Surveys and individual interviews with key stakeholders to determine acceptability, appropriateness, and feasibility of the proposed approach and toolkit

A knowledge co-production strategy to address systematic non-compliance with MDA for Lymphatic Filariasis in Leogane, Haiti

The researchers propose taking a novel approach to increase coverage and reach previously neglected populations by engaging non-compliant individuals in devising a more effective strategy through a technique called knowledge co-production. The researchers plan to address the following questions:

  1. Can an intervention package co-produced with systematically non-compliant individuals result in increased MDA coverage between the 2019 and 2020 LF MDA rounds?
  2. Who and where are the systematic non-compliers in Leogane and Gressier?
  3. What are the reasons motivating systematic non-compliance?
  4. Is MDA non-compliance associated with hotspots of LF transmission?

The researchers plan the following activities:

  1. A household cluster survey with 1300 individuals of all ages. This will define coverage in the past MDA and identify non-compliant individuals. In addition, ‘hidden’ non-compliers (NCs) will be located by a networking approach (respondent-driven sampling [RDS]).
  2. All NCs will then be eligible to be selected into groups of 10 by age (18-25; 26-50; >50), sex (M, F) and demography (urban/rural). These 12 groups will each work with the national health team to devise new approaches to the non-compliance issue. These will be put into place for the 2020 MDA and then assessed by the co-production strategy groups. After the 2020 MDA a second survey will occur to assess impact.
  3. The relationship between non-compliance and hotspots will be assessed using spatial analysis and defined serologically (FTS and DBS for antibodies) in collaboration with CDC.

Investigating the role of drug delivery strategy in MDA drug coverage

Haiti, like many other countries, has made considerable progress in the elimination of lymphatic filariasis. To date, 118 out of 140 communes have passed TAS and stopped MDA. However, little is understood about why some communes have persistent transmission despite five or more rounds of MDA. The proposed study aims to identify alternative approaches to MDA that may help to increase access, uptake, and coverage, particularly for individuals who typically do not comply with MDAs. This cluster-randomized design will test a novel approach (door to door strategy) against the standard health post-based delivery method. Additionally, the study aims to identify non-compliant individuals and better understand their reasons for non-participation. Furthermore, a cost analysis will be undertaken as part of this study to understand the potential implications for the country program should the door-to-door strategy prove effective in reaching higher numbers of people.
