Protocol for the crowdsourced image-based morbidity hotspot surveillance for neglected tropical diseases (CIMS-NTDs).

INTRODUCTION: Efficient NTDs elimination strategies require effective surveillance and targeted interventions. Traditional methods are costly and time-consuming, often failing to cover entire populations in case of movement restrictions. To address these challenges, a morbidity image-based surveillance system is being developed. This innovative approach which leverages the smartphone technology aims at simultaneous surveillance of multiple NTDs, enhancing cost-efficiency, reliability, and community involvement, particularly in areas with movement constraints. Moreover, it holds promise for post-elimination surveillance. METHODOLOGY: The pilot of this method will be conducted across three states in southern Nigeria. It will target people affected by Neglected Tropical Diseases and members of their communities. The new surveillance method will be introduced to target communities in the selected states through community stakeholder's advocacy meetings and awareness campaigns. The pilot which is set to span eighteen months, entails sensitizing NTDs-affected individuals and community members using signposts, posters, and handbills, to capture photos of NTDs manifestations upon notice using smartphones. These images, along with pertinent demographic information, will be transmitted to a dedicated server through WhatsApp or Telegram accounts. The received images will be reviewed and organized at backend and then forwarded to a panel of experts for identification and annotation to specific NTDs. Data generated, along with geocoordinate information, will be used to create NTDs morbidity hotspot maps using ArcGIS. Accompanying metadata will be used to generate geographic and demographic distributions of various NTDs identified. To protect privacy, people will be encouraged to send manifestation photos of the affected body part only without any identifiable features. EVALUATION PROTOCOL: NTDs prevalence data obtained using conventional surveillance methods from both the pilot and selected control states during the pilot period will be compared with data from the CIMS-NTDs method to determine its effectiveness. EXPECTED RESULTS AND CONCLUSION: It is expected that an effective, privacy-conscious, population inclusive new method for NTDs surveillance, with the potential to yield real-time data for the identification of morbidity hotspots and distribution patterns of NTDs will be established. The results will provide insights into the effectiveness of the new surveillance method in comparison to traditional approaches, potentially advancing NTDs elimination strategies.

Factors associated with health seeking delay in the screening of cervical cancer among women in Imo state, south Eastern Nigeria.

BACKGROUND TO THE STUDY: Cervical cancer is a curable disease if diagnosed early. The mortality rate due to cervical cancer is high worldwide, mainly because of the absence of a functioning screening process and the advanced stage of the disease at diagnosis. The aim of this study was to assess the factors associated with health-seeking delay in the screening of cervical cancer among women in Owerri Municipal LGA, Imo State. METHODS: A descriptive cross-sectional research design was employed in this study on factors associated with health-seeking delay in the screening of cervical cancer among women in Owerri Municipal LGA. A semi-structured questionnaire was used for the study, and Statistical Package for the Social Sciences (SPSS) version 20 was used in the analysis of the data gotten from the study. A probability-based multi-stage sampling method was adopted for the study in recruiting 432 women who participated in it. RESULT: Results from the study showed that most of the women, 117 (27.1 %), were between the ages of 22 and 27. The study found that a high percentage of the respondents, 350 (81.0 %), had heard about cervical cancer screening, and when they were asked who they thought should be screened for cervical cancer, 154 (35.6 %) said women between the ages of 15 and 40. Further findings revealed that, 420 (97.2 %) said they had not been screened for cervical cancer. The study also demonstrated that 260 (60.2 %) believe long distance has an impact on your access to health care. The findings of this study revealed that age (P = 0.0247), educational level of women (P = 0.0214), and monthly income of the women (P = 0.0062) were all significantly associated with health-seeking delay in cervical screening. CONCLUSION: The study concluded that there is no limited knowledge about cervical cancer among women in Owerri Municipal. Long distance to screening facilities, educational background, and monthly income are significantly associated with the delay in seeking health services for cervical screening. RECOMMENDATION: The study recommended that there should be massive awareness and participation in the screening program across the state.

Determinants of cervical cancer screening uptake among female undergraduates in a tertiary institution in south eastern Nigeria: a cross sectional study.

INTRODUCTION: Cancer of the cervix is the second most common cancer among women worldwide and is the major cause of cancer deaths in developing countries. Screening is among the common cost-effective control methods for the disease. This study ascertained the determinants of cervical cancer screening uptake among female undergraduates in a tertiary institution in south eastern Nigeria. METHODS: This cross-sectional study was conducted using a stratified sampling technique among 375 respondents. A pretested semi structured questionnaire was used for data collection and SPSS version 21 was used in data analysis in which the association between qualitative variables was ascertained using Chi-square test at P < 0.05 probability level. RESULTS: The result revealed that majority of 321 (85.6%) were aware of CC as a disease and 202 (53.9%) of the respondents were aware of cervical cancer screening test. The study revealed that the uptake of cervical cancer screening was low among the female undergraduates. Only few 27 (7.2%) of the respondents have been previously screened for cervical cancer. High cost of screening 128 (31.2%) was the major reason for not undergoing screening. Significant association existed between socio-demographic variables (age, level of study, marital status and monthly allowance) and uptake of cervical cancer. Most of the respondents 10 (17.2%) that had been screened for cervical cancer were within the age bracket of 25-29 years and were in 500 level 21(19.4%). Cervical cancer uptake was higher 9 (29%) in married females compared to single females 18 (5.2%). It was also indicated that all the participants who have been screened were screened at a cost of ₦ 1,001 - ₦ 2,000. Majority of them 11 (25.6%) earned monthly allowance of ₦ 23,001 - ₦ 30,000. Strong association were also found between awareness of cervical cancer (X² = 4.89, P = 0.027), availability of screening center (X² = 37.433, P ≤ 0.001), cost of screening (X² = 100,793, P ≤ 0.001) and uptake of screening. CONCLUSIONS: The study revealed that the uptake of cervical cancer screening was low among the female undergraduates. In order to enhance screening uptake among female undergraduates, there is an urgent need to review the cost of screening especially in the school's health center and other hospitals/clinics within the school environment.

Drug Shop Intervention to Enhance Knowledge, Attitude, and Practices of Patent Medicine Vendors for the Control of COVID-19 In Southeastern Nigeria.

Drug shops are the first point of care for most community members in low-resource countries. Because of symptomatic similarities with common illnesses such as malaria, probable coronavirus disease 2019 (COVID-19) cases may seek care at drug shops, where the knowledge and skills required to handle it may be lacking, thereby fostering community spread of the disease. This single-arm study provided an intervention to improve COVID-19-related knowledge, attitude, and practices of patent medicine vendors (PMVs) in 97 participating drug shops selected through cluster sampling in Owerri, southeastern Nigeria. The intervention involved a drug shop sensitization using information, education, and communication material, as well as training on the use of a risk assessment checklist to identify probable COVID-19 cases and to take appropriate action. Data were collected to determine the effect of this intervention using a pre-tested questionnaire and practice observation checklist, first at baseline and then 3 months post-intervention. Data analysis involved exploratory analysis and the t-test to determine pre- and post-intervention mean score differences at the 5% α level. There was post-intervention knowledge improvement on the COVID-19 causative pathogen (98.1% post-intervention versus 61.9% pre-intervention) and disease transmissibility from person to person (95.9% post-intervention versus 81.4% pre-intervention) among other knowledge domains. There was significant post-intervention improvement for positive attitude, with a mean gain score of 2.8 ± 1.7 (t = 4.4, P = 0.005), and preventive practices, with a mean gain score of 6.0 ± 4.7 (t = 4.1, P = 0.007). Engaging patent medicine vendors in the pandemic response plans through targeted interventions such as drug shop intervention could prove vital in the fight against COVID-19.

Knowledge, attitude and perception on cervical cancer screening among women attending ante-natal clinic in Owerri west L.G.A, South-Eastern Nigeria: A cross-sectional study.

BACKGROUND: Cancer of the cervix is the second most common cancer in women globally, and it is a major cause of morbidity and mortality among women in developing countries such as Nigeria. The study assessed the knowledge, attitude and perception on cervical cancer screening among women attending ante-natal clinic in Owerri West, south eastern Nigeria. METHOD: This cross-sectional study was conducted using a random sampling technique among 231 respondents attending ante-natal clinic in a cluster of 4 selected public primary healthcare centres. A structured questionnaire was used for data collection, and data obtained was analysed using a descriptive technique, while the chi-square test was used to test for the influence of age and education level on cervical cancer screening. RESULTS: The result showed that there was a high level of awareness (68.8%) of cervical cancer screening. The majority of women (122 (52.8%)) received this information from friends. Although the majority of the participants had heard about the screening, few of them had basic information on the cause of the disease 44 (19%), prevention 32 (13.9%), risk factors 48 (20.8%) and treatment (23.4%) of the disease. Of the 231 women, 59 (25.5%) strongly agreed they were too young to have cervical cancer and hence there was no need for the screening, while a greater proportion (53 (22.9%)) agreed that the screening is only meant for older women (30-45 years). Expensive cost of screening (68 (29.4%)) and invasion of privacy by male doctors (34.6%) were also strong reasons for avoiding screening. The study revealed strong influence of age (χ2 = 104.37; DF = 10; P<0.001) and level of education (χ2=31.63; DF = 6; P<0.001) on awareness of cervical cancer screening. Moreover, educational status had a significant positive influence (χ2= 54.71; P<0.001) on the cause of cervical cancer, with a higher proportion of participants with post-secondary education. CONCLUSION: Awareness of cervical cancer is high, but the perception that it can be treated is quite low, along with fear of the screening outcome. Age and level of education are significant factors of screening for cervical cancer. Educational programmes encouraging participation in cervical cancer screening should consider involving the use of close peers and friends to educate the women on the importance of screening program.

Malaria care-seeking behaviour among HIV-infected patients receiving antiretroviral treatment in South-Eastern Nigeria: A cross-sectional study.

This study assesses malaria prevention and treatment behaviour among people living with HIV/AIDS (PLWHA) in Owerri, South Eastern Nigeria. Although Nigeria bears one of the world's largest burdens of both malaria and HIV, there is almost no research studying how co-infected patients manage their care. We systematically sampled 398 PLWHA receiving care at Imo State Specialist Hospital and the Federal Medical Centre in Owerri to complete a structured, pre-tested questionnaire on malaria care-seeking behaviour. Descriptive statistics were reported and chi-square tests and multivariate logistic regressions were also used. The majority of HIV-infected patients (78.9%) reported having had an episode of suspected malaria quarterly or more often. There was a large variation in care-seeking patterns: on suspicion of malaria, 29.1% of participants engaged in self-medication; 39.2% went to drug shops, and only 22.6% visited HIV/AIDS care centres. Almost 40% waited more than 24 hours before initiating treatment. Most (60.3%), reported taking recommended artemisinin-based combination treatments (ACT) but a significant minority took only paracetamol (25.6%) or herbal remedies (3.5%). Most (80%) finished their chosen course of treatment; and completion of treatment was significantly associated with the frequency of suspected malaria occurrence (p = 0.03). Most (62.8%) did not take anti-malaria medication while taking antiretroviral treatment (ART) and almost all (87.6%) reported taking an ACT regimen that could potentially interact with Nigeria's first-line ART regimen. Our findings suggest the need to pay more attention to malaria prevention and control as a crucial element in HIV/AIDS management in this part of Nigeria and other areas where malaria and HIV/AIDS are co-endemic. Also, more research on ART-ACT interactions, better outreach to community-level drug shops and other private sector stakeholders, and clearer guidelines for clinicians and patients on preventing and managing co-infection may be needed. This will require improved collaboration between programmes for both diseases.

Awareness, perceptions and intent to comply with the prospective malaria vaccine in parts of South Eastern Nigeria.

BACKGROUND: There are potentials of a malaria vaccine being developed sooner than expected. While focus is more on the development of a vaccine, less attention has been paid on the extent to which such vaccines could be well accepted and the readiness among caregivers to comply with its use in order to achieve the effectiveness of the vaccine in the malaria endemic areas. Compliance rates are influenced by the level of awareness, as well as the perception of the population. This cross-sectional study was aimed at assessing the awareness, perceptions and intent to comply with the prospective malaria vaccine by caregivers in Owerri West, South Eastern Nigeria. METHODS: Structured pretested questionnaires were used to collect data from 500 randomly selected consenting care givers (mostly mothers). Items used to assess the intent to comply with the vaccine include willingness to accept and use the vaccine, and allow children to be vaccinated. RESULTS: The study found that awareness of malaria as a public health problem was high (89.8%), but awareness about a prospective malaria vaccine was not high (48.2%). Up to 88.2% of respondents showed positive perception towards the vaccine, of which 65.2% had strong positive perception. The study found high level of intent to comply with the prospective malaria vaccine among the study group (95.6% positive). Significant association was established between caregivers perception and intent to comply with the prospective malaria vaccine (χ2 = 144.52; p < 0.0001). CONCLUSIONS: While malaria vaccine adoption is likely to be a welcome development in South Eastern Nigeria, proper consideration should be given to factors that are likely to influence people's perceptions about vaccines in the plans/process of malaria vaccine development and vaccination programmes.

Determinants of delay in seeking malaria treatment for children under-five years in parts of South Eastern Nigeria.

One of the components of the current WHO strategy to fight malaria is early recognition and prompt and appropriate treatment. We investigated determinants of delay in seeking early and appropriate malaria treatment for children (0-5 years) in Ohaji/Egbema, South Eastern Nigeria. Data was collected using structured pre-tested questionnaires elicited in the local language (Igbo) to 738 consenting mothers within the child bearing age (15-49 years). About twenty-two percent (22%) of the respondents sought treatment within 24 h for their children with malaria and were excluded from further investigation. More than half of the remaining respondents (51.5%) delayed in seeking treatment because they had to watch their children for some days, while 21.4% were due to financial difficulties. The age, parity, marital status/type of marriage and educational attainment of the mothers including family social-economic status were found to be statistically related to delay in seeking appropriate treatment (P < 0.05). Wrong first line treatment choices by the respondents also contributed to this delay. These results underscore the need to improve awareness of mothers and caregivers on the need and ways of seeking early, appropriate and effective treatment for their children who have malaria. This is very important if the WHO strategy of early recognition, prompt and appropriate treatment is to be effective so as to sufficiently reduce mortality and morbidity due to malaria among children in endemic rural areas. It will also aid in the proper management and treatment of other childhood febrile illnesses.

Malaria transmission and morbidity patterns in holoendemic areas of Imo River Basin of Nigeria.

BACKGROUND: This study determines the relationship between malaria transmission intensity and morbidity in holoendemic areas of Imo River Basin, Nigeria. RESULTS: Standard entomological and parasitological techniques were used to determine transmission intensity and parasite rates respectively while sociocultural methods and review of hospital records were used to determine morbidity patterns. The average transmission rate was 16.1 infective bites per person per night (ib/p/n). The average malaria specific morbidity rate for the study area was 30.2%. These parameters showed no significant differences among the communities studied (P > 0.05). Transmission intensity and morbidity rate had a linear relationship such that high transmission intensity corresponded with high morbidity rate and vice versa. CONCLUSIONS: This therefore puts to rest discrepancies about the relationship between malaria transmission and morbidity in the study area and calls for serious scaling up of the insecticide treated nets strategy especially in high transmission areas and seasons. Concerted efforts should also be made towards production of transmission blocking vaccines.

Clinical and parasitological aspects of onchocercal skin diseases in Nigeria.

An assessment of onchocercal skin disease (OSD) conducted in 38 rural communities in the Imo River Basin, Nigeria, between March 1999 and September 2000, showed that depigmentation (DPM) was the most prevalent lesion in persons with skin microfilariae (mf) (26.3%), followed by chronic papular onchodermatitis (CPOD) (18.1%) and acute papular onchodermatitis (APOD) (15.5%). There was no significant difference (P > 0.05) in sex-related prevalence of OSD. While CPOD, lichenified onchodermatitis (LOD) and DPM were more prevalent in subjects over 30 years old, APOD was associated more with those aged less than 30 years. OSD occurred with concomitant itching in nearly 50% of subjects. The geometric mean intensity of infection was 13 mf/mg per skin snip.

Prevalence of Mansonella perstans infections among the nomadic Fulanis of northern Nigeria.

The study was undertaken to investigate the prevalence and clinical manifestations of Mansonella perstans infection in the nomadic Fulanis of northern Nigeria. Physical examination of 755 consenting nomads for clinical manifestations of M. perstans infection was carried out between June 1996-September 2000. This was followed by parasitological examination of blood samples collected by finger prick method to identify microfilariae (mf). Data collected was stratified by locality, age and sex, and analyzed using the Chi-square test. Overall, 66 (8.7 %) of 755 nomads were infected. Infection was higher in men (9.7 %) than in women (6.5 %) (p<0.05) and occurred in all age groups with highest prevalence in persons in the 4th (14.1 %) and 5th (17.1 %) decades of life. Fifty-six (81.8 %) of the 66 nomads with mf had clinical manifestations with periodic dizziness (18.2 %), body itching (15.2 %) was the most prevalent while back pain (7.6 %) was the least. The findings show that mansonelliasis is an important health problem in nomads. This underscores the need to establish a well-articulated Filariasis Control Programme for this group whose major health problems are rooted in their occupation and amplified by several contingencies of the environment.

Onchocerciasis in Imo state, Nigeria (2): the prevalence, intensity and distribution in the upper Imo river basin.

Human infection with Onchocerca volvulus was investigated in 13 rural communities in the Upper Imo River basin, Imo State, Nigeria between March 1997 and December 2000 using the skin snip method. Of the 3,311 persons examined, 889 (26.8%) had microfilariae. There were significant differences between communities in microfilariae prevalence and intensity of infection (P<0.05). Sex infection was similar in males (26.8%) and females (26.9%); whereas farmers (46.6%) and fishermen (28.4%) were more affected than people in other occupations. The proportion of infected persons increased with age coinciding with the period when most clinical signs manifest. A significant proportion of the 889 persons with positive microfilariae skin biopsy had musculoskeletal pain (57.1%). Thirty-four (47.2%) of the 72 epileptics identified had positive skin biopsy in addition to other manifestations. The present findings show that onchocerciasis is a public health problem in the area. The use of ivermectin has reduced the incidence of the disease when compared with data from the pre-ivermectin era. This shows that Community Directed Treatment with Ivermectin (CDTI) campaign is successful and should be sustained until onchocerciasis is eliminated as a public health problem in the area.

Control of endemic dracunculiasis in Ebonyi state, south-eastern Nigeria.

A field study was carried out in Ozibo and the Ebonyi local government area of Ebonyi state, south-eastern Nigeria to determine the effectiveness of several intervention strategies in the control of endemic dracunculiasis in that area. During the initial study prior to the application of such measures, 14,421 subjects were examined. A total of 8,688 (60.2%) persons had either Dracunculus ulcers or emergent worms. Sex-related prevalence rates were 56.1% and 63.9% for males and females respectively. Age specific prevalence rates increased with age in males, whereas highest infection rates were found in females younger than 20 years. Twenty-eight months after the introduction of intervention strategies the prevalence rate fell by 85.1% to 9% (males: by 88.2% to 6.6%, females: by 83.0% to 10.8%). Reduction rates of more than 90% were observed in males aged 10 to 19 and in females aged 0 to 9 years. Intervention measures included systematic pond treatment, distribution or replacement of filters, intensive health education, provision of hand-dug wells, regular bore-hole installation/rehabilitation as well as active case detection, containment, management, and prompt reporting. Active involvement of the endemic communities, governments and the Global 2000 staff regarding the control efforts is a necessity towards the final eradication of the disease in the near future. The relationship between some of these intervention strategies and community development are highlighted.
