            <h1>Factors Influencing Iron Levels Among Women of Reproductive Age and Children 6–48 Months in Livestock-Keeping Communities in Narok County, Kenya</h1>

              <h3>Abstract</h3>
                <p>Proper nutrition is vital for maintaining good health for all people across their lifespan, especially children and mothers, who are especially vulnerable due to their specific nutrient needs. Despite the necessity of improved nutrition for these groups, some members do not fully meet their recommended daily micronutrient needs, a challenge exacerbated by different socioeconomic, cultural, and communal constraints resulting in malnutrition. Iron deficiency anaemia is a major concern among children and mothers, especially in pastoralist communities, due to poor nutrition and other related factors. Using a community-based cross sectional study, this study investigated factors associated with hemoglobin levels among children and women in Narok County, Kenya. Anthropometrics were estimated using body mass index measurements for mothers, and the nutritional status of children was calculated using Z-score measurements. Haemoglobin was measured using a rapid test (Hemocue 301). Multiple logistic regression models were fitted to assess the association between child and maternal risk factors and anaemia. Anaemia in children was associated with age (OR = 1.99, p = 0.047), pastoralism (OR = 2.25, p = 0.002), educational of the mother (OR = 0.74, p = 0.008), severe and moderate undernourishment (OR = 1.14, p = 0.049 and OR = 1.10, p = 0.023), respectively, not meeting children dietary diversity (OR = 1.18, p = 0.027), number of people in a household (OR = 1.84, p = 0.003), and maternal age (OR = 0.30, p = 0.010). On the other hand, the occurrence of anaemia in women was associated with pastoralism (OR = 2.22, p = 0.001), having a primary school level of education (OR = 0.51, p = 0.028), pregnancy status (OR = 5.36, p = 0.002), not meeting maternal dietary diversity (OR = 1.39, p = 0.026), number of household members (OR = 1.93, p = 0.023), age of the mother (OR = 0.53, p = 0.018), and having animals infected with East Coast Fever (Theileria parva) within the household (OR = 1.10, p = 0.023). The results highlight the multifaceted nature of malnutrition, specifically anaemia in pastoral households, with interventions aimed at reducing disease infections in cattle, improved household dietary diversity, and community health education geared towards maternal and child nutrition being best placed to improve the overall household health outcomes relating to anaemia.</p>

    Background

    Kenya launched a Rabies Elimination Strategy in 2014, aiming to end human rabies deaths by 2030. In March 2022, Lamu County reported increased cases of human dog bites and suspected rabies deaths to the Ministry of Health (MoH). We aimed to establish the extent of the rabies outbreak in humans and animals and determine the challenges to achieving rabies elimination by 2030.

    Methods

    We extracted dog bite reports from the Kenya Health Information System (KHIS), national surveillance database system, and reviewed medical records at health facilities in Lamu County for suspected human rabies deaths from 2020 to 2022. We obtained information about animal bites and illnesses in deceased persons, checked the availability of anti-rabies vaccines in health facilities, and administered rabies knowledge and practice questionnaires to health workers. For categorical data, frequencies and proportions were determined.

    Results

    There were 787 dog bite cases and six human rabies cases. Only a third (2/6) of the rabies cases were uploaded to the KHIS. The county used targeted dog vaccination, and samples were not collected from the biting dogs. Regarding the availability of human rabies vaccines, half (8/16) of the facilities had the human rabies vaccine, and 19% (3/16) had both the human rabies vaccine and rabies immunoglobulin (RIG). Rabies vaccine stock-outs were common at 73% (11/16). Only 25% (18/73) of the health workers reported their first action would be to clean the bite wound with running water and soap for 15 min. Additionally, 86% (54/63) did not know the recommended human rabies vaccine and RIG dosage and schedule, while 25% (18/73) of healthcare workers were satisfied with the existing information-sharing mechanisms between veterinary and human health departments for rabies prevention and control.

    Conclusions

    There was underreporting of rabies cases, a lack of awareness of bite wound management at health facilities, and persistent stockouts of human rabies vaccines. We suggest training healthcare workers on animal bite case management and improving One Health information exchange.
