COVID-19 vaccination intention among internally displaced persons in complex humanitarian emergency context, Northeast Nigeria.

Internally displaced persons (IDPs) are at high risk for COVID-19 transmission because of congested and unsanitary living conditions. COVID-19 vaccination is essential to build population immunity and prevent severe disease among this population. We determined the prevalence and factors associated with intention to accept COVID-19 vaccine among IDPs in Northeast Nigeria. This cross-sectional study, conducted during July-December 2022, included 1,537 unvaccinated IDPs from 18 IDPs camps. We performed a complex sample survey analysis and described participants' characteristics and vaccination intention with weighted descriptive statistics. We fitted weighted logistic regression models and computed adjusted odds ratios with 95% confidence intervals to identify factors associated with intention to accept COVID-19 vaccine. Of 1,537 IDPs, 55.4% were 18-39 years old, 82.6% were females, and 88.6% had no formal education. Among them, 63.5% (95% CI: 59.0-68.1) expressed intention to accept COVID-19 vaccine. Among the IDPs who intended to reject vaccine, 42.8% provided no reason, 35.3% had COVID-19 misconceptions, 9.5% reported vaccine safety concerns, and 7.4% felt no need. IDPs who perceived COVID-19 as severe (Adjusted Odds Ratio (AOR) = 2.31, [95% CI: 1.35-3.96]), perceived COVID-19 vaccine as effective (AOR = 4.28, [95% CI: 2.46-7.44]) and resided in official camps (AOR = 3.29, [95% CI: 1.94-5.56]) were more likely to accept COVID-19 vaccine. However, IDPs who resided 2 kilometers or farther from the nearest health facility (AOR = 0.34, [95% CI: 0.20-0.58]) were less likely to accept vaccine. Intention to accept COVID-19 vaccine among the IDPs was suboptimal. To improve vaccination acceptance among this population, health education and risk communication should be intensified to counter misinformation, strengthen vaccine confidence, and shape perception of COVID-19 severity, focusing on IDPs in unofficial camps. Appropriate interventions to deliver vaccines to remote households should be ramped up.

Knowledge, risk perception and uptake of COVID-19 vaccination among internally displaced persons in complex humanitarian emergency setting, Northeast Nigeria.

BACKGROUND: Owing to crowded and unsanitary conditions, internally displaced persons (IDPs) have an increased risk of COVID-19 infection. Adoption of COVID-19 preventive measures among this population is premised on accurate information, adequate knowledge, and risk perception. We assessed COVID-19 knowledge and risk perception and investigated the association between risk perception and COVID-19 preventive measures, including vaccination among IDPs in Northeast Nigeria. METHODS: We conducted a cross-sectional study during July-December 2022 and sampled 2,175 IDPs using stratified sampling. We utilized a 12-point assessment tool to evaluate COVID-19 knowledge. Participants who scored ≥ 6 points were considered to have adequate knowledge. We used a 30-item Risk Behavior Diagnosis Scale to assess COVID-19 risk perception and evaluated each item on a 5-point Likert scale. Participants were divided into risk perception categories by the median of Likert scale scores. We performed weighted logistic regression analysis to identify factors associated with risk perception. Pearson's chi-squared with Rao-Scott adjustment was used to determine the relationship between risk perception and COVID-19 preventive measures. RESULTS: Of 2,175 participants, 55.7% were 18-39 years old, 70.9% were females, and 81.7% had no formal education. Among the IDPs, 32.0% (95% CI: 28.8 - 35.0) were considered to have adequate COVID-19 knowledge, and 51.3% (95% CI: 47.8 - 54.8) perceived COVID-19 risk as high. Moreover, 46.3% (95% CI: 42.8 - 50.0) had received one dose of COVID-19 vaccine, and 33.1% (95% CI: 29.8 - 36.0) received two doses. Adequate knowledge (Adjusted Odds Ratio (AOR) = 2.10, [95% CI: 1.46 - 3.03]) and post-primary education (AOR = 3.20, [95% CI: 1.59 - 6.46]) were associated with risk perception. Furthermore, high risk perception was significantly associated with wearing face masks (χ2 = 106.32, p-value < .001), practicing hand hygiene (χ2 = 162.24, p-value < .001), physical distancing (χ2 = 60.84, p-value < .001) and vaccination uptake (χ2 = 46.85, p-value < .001). CONCLUSIONS: This study revealed gaps in COVID-19 knowledge, risk perception, and vaccination uptake but demonstrated a significant relationship between risk perception and COVID-19 preventive practices. Health education and risk communication should be intensified to improve knowledge, elicit stronger risk perception, and enhance COVID-19 preventive practices.

Factors associated with health-seeking patterns among internally displaced persons in complex humanitarian emergency, Northeast Nigeria: a cross-sectional study.

BACKGROUND: Currently, over two million persons are internally displaced because of the complex humanitarian emergency in Nigeria's northeast region. Due to crowded and unsanitary living conditions, the risk of communicable disease transmission, morbidity, and mortality among this population is high. This study explored patterns and factors associated with health-seeking among internally displaced persons (IDPs) in northeast Nigeria to inform and strengthen disease surveillance and response activities. METHODS: In a cross-sectional study conducted during June-October 2022, we employed stratified sampling technique to select 2,373 IDPs from 12 IDPs camps. A semi-structured tool was used to collect data on health-seeking patterns, socio-demographics, households, and IDPs camps characteristics. We classified health-seeking patterns into three outcome categories: 'facility care' (reference category), 'non-facility care' (patent medicine vendors, chemists, traditional healers, religious centers), and 'home care/no care'. We performed complex survey data analysis and obtained weighted statistical estimates. Univariate analysis was conducted to describe respondents' characteristics and health-seeking patterns. We fitted weighted multivariable multinomial logistic regression models to identify factors associated with health-seeking patterns. RESULTS: Of 2,373 respondents, 71.8% were 18 to 39 years old, 78.1% were females, and 81.0% had no formal education. Among the respondents, 75.7% (95% CI: 72.9-78.6) sought 'facility care', 11.1% (95% CI: 9.1-13.1) sought 'non-facility care', while 13.2% (95% CI: 10.9-15.4) practiced 'home care/no care'. Respondents who perceived illness was severe (Adjusted Odds Ratio (AOR) = 0.15, [95% CI: 0.08-0.30]) and resided in officially-recognized camps (AOR = 0.26, [95% CI: 0.17-0.39]) were less likely to seek 'non-facility care' compared to 'facility care'. Similarly, respondents who resided in officially-recognized camps (AOR = 0.58, [95% CI: 0.36-0.92]), and received disease surveillance information (AOR = 0.42, [95% CI: 0.26-0.67) were less likely to practice 'home care/no care' rather than seek 'facility care'. CONCLUSIONS: This population exhibited heterogeneous patterns of health-seeking at facility and non-facility centers. Perception of illness severity and camps' status were major factors associated with health-seeking. To enhance surveillance, non-facility care providers should be systematically integrated into the surveillance network while ramping up risk communication to shape perception of illness severity, prioritizing unofficial camps.
