Abstract Background Early diagnosis of malaria and treatment seeking behavior play key role in controlling and preventing further complication related to malaria disease. Aim of this study was to determine the responses on early malaria diagnosis and treatment seeking behavior among outpatient clients attending at Sekou toure regional referral hospital in Mwanza, Tanzania. Methods A cross-sectional study was conducted among outpatient client at Sekou-Touré regional referral hospital, convenient simple random sampling used and self-administered questionnaire were used to collect data and data was entered into Microsoft excel and then exported to SPSS version 25.0 for further analysis and presented on the percentages and table. The analysis of strength of relationships between categorical variables was conducted using the Chi-square test. A p-value of ≤ 0.05 was considered to be statistically significant. Results A total of 192 respondents completed the study with a response rate of 97.6%. The study revealed that Most of the respondents about 90.6% stated they would seek treatment from health facility when symptoms appear. However, only 6.3% seek treatment within 24 hours of onset of illness (p= 0.017). Half of respondents (50.5%) experienced malaria symptoms in the past six months and only 30% seek for treatment at health facility. Preference of health facility, (51%) respondents were going direct to pharmacy to buy medicine for self-treatment. Overall, cost of service, time consumed and distance of health facility especially health center shows significant with such delay. Conclusion A low proportion of malaria-suspected patients sought treatment within 24 h of fever onset compared to the national target. Distance from the health facility, cost of service and time consumed were found to be predictors of early treatment-seeking behavior for malaria. Strengthening strategies tailored to increasing awareness for communities about malaria, importance of going hospital and early treatment-seeking behavior is essential.

Abstract Background Currently, malaria rapid diagnostic tests (mRDTs) are increasingly used for the diagnosis of malaria, particularly in communities where microscopy-based diagnosis is not practical. However, the diagnostic accuracy of mRDTs performed by community health workers (CHWs) remains unknown. This study was conducted to determine the accuracy of mRDT results performed by CHWs in Ngoma district, eastern province of Rwanda. Method This was a cross sectional prospective study. A total of 420 blood samples of patients self-reported to CHWs for malaria diagnosis were collected and analyzed by CHWs using mRDT, and quality control tests were performed by using microscopy as a reference test. The study was conducted from 22 April to 08 July 2021. Results Among the 420 patients, 234 (55.71%) were females, and 186 (44.29%) were males. Malaria test positivity was 2.62% by using mRDT and 1.67% by using microscopic tests. The sensitivity and specificity of mRDT were 85.71% and 98.78%, respectively. The negative predictive value, positive predictive value and accuracy of mRDTs were 99.75%, 54.54% and 98.57%, respectively. The sensitivity of mRDT was below the WHO recommended sensitivity (>95%), although the specificity (98.78%) was within the WHO recommended specificity (>=90). There was substantial agreement between the mRDT and malaria microscopic test results, k=0.642. Conclusion mRDTs continue to be an appropriate choice for malaria diagnosis in the absence of microscopy.

Malaria is one of the most common parasitic diseases causing a significant burden on health care, especially in India. Light microscopy, the gold standard for malaria diagnosis is time-consuming especially in a setup where the caseload is high and parasite index is low. Knowledge of abnormal scattergrams by the malarial parasite is very essential to suspect malaria and screen those cases thoroughly on a peripheral smear for accurate diagnosis. A timely and accurate diagnosis is crucial to the prognosis of this disease. Herein, we report a case of a 40-year-old male from Punjab who presented to the emergency with fever and an altered sensorium. Analyzer showed characteristic pseudo eosinophilia with greying of neutrophil eosinophil zone with double eosinophil cluster. According to flagging rules because of eosinophilia, peripheral blood film (PBF) was made and examined, which revealed Plasmodium falciparum gametocytes.

An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ2-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

Objectives. The objectives of this study were to evaluate the trend of malaria cases and test positivity rate and explore determinant factors in the Amhara Regional State, Ethiopia. Methods. A mixed study design (retrospective record data review and case study) was employed among 67 malaria officers from all zones in the region by using proportional allocation and the 1995 to 2020 malaria document review. 1995 to 2020 trend analysis was conducted using RStudio-1.2.5033. Vignette Focus Group Discussions (FGDs) were used to dig the possible factors for malaria case buildup using the purposive sampling technique, and a qualitative content analysis was used. Results. The overall mean test positivity rate (TPR) was 21.9%, and about 80% of the land of the region was malarious, and 68% of the population was at risk of malaria in the study area from the data records of 1995 to 2020. The year 2012 to 2016 had the peak confirmed malaria cases, while the year 2016 to 2018 dramatically reduced followed by an increase in 2019/2020. The vignette FGDs identified that poor performance on Larval Source Management (LSM) and net utilization, no stock of some antimalarial medicine and supply, quality of malaria diagnosis services, the low commitment of leaders, and climatic anomalies facilitated surge of the disease in 2019/2020. No real accountability at all levels, low coverage of targeted vector control interventions, resource constraint, data quality and use for informed decision making, security issues and Internally Displaced Population (IDP) in various parts of the country, and the COVID-19 pandemic were the possible causes for case buildup. Conclusions. This result revealed that the malaria incidence rate showed a remarkable decline. However, the average TPR was 21.9%. Hence, it provided the ongoing feedback, mass fever test and treatment, training to health professionals, and ongoing supportive supervision (SS) and mentorship, improved net utilization and indoor residual spraying (IRS) operation and close follow-up and conducted sensitization workshop, spot messages were transferred through mass media, and temporary case treatment and prevention centers at farm sites established may surpass the threshold of malaria.

Malaria eradication has for decades been on the global health agenda, but the causative agents of the disease, several species of the protist parasite Plasmodium, have evolved mechanisms to evade vaccine-induced immunity and to rapidly acquire resistance against all drugs entering clinical use. Because classical antimalarial approaches have consistently failed, new strategies must be explored. One of these is nanomedicine, the application of manipulation and fabrication technology in the range of molecular dimensions between 1 and 100 nm, to the development of new medical solutions. Here we review the current state of the art in malaria diagnosis, prevention, and therapy and how nanotechnology is already having an incipient impact in improving them. In the second half of this review, the next generation of antimalarial drugs currently in the clinical pipeline is presented, with a definition of these drugs’ target product profiles and an assessment of the potential role of nanotechnology in their development. Opinions extracted from interviews with experts in the fields of nanomedicine, clinical malaria, and the economic landscape of the disease are included to offer a wider scope of the current requirements to win the fight against malaria and of how nanoscience can contribute to achieve them.

The United Kingdom’s cases of malaria infection are primarily acquired in sub-Saharan Africa, with the majority of infections presenting in London.1 When patients go to a hospital with malaria, there is a screening opportunity for other geographically associated chronic infections. We identified patients who were diagnosed with malaria after presenting to our emergency department in London over a 2-year period, to assess whether there may be clinical benefit in screening for chronic viral (hepatitis B, hepatitis C, HIV) or parasitic (schistosomiasis, strongyloidiasis) infection in this cohort. Over this period, 131 patients were diagnosed with malaria. Crude seropositivity rates for HIV, hepatitis B, and strongyloidiasis were higher than expected compared with local population estimates, 7 and 28 times higher for HIV and hepatitis B, respectively. Those patients with previously unidentified cases were offered appropriate treatment. These findings support the potential clinical and public health benefits of screening for other infectious diseases in the context of a malaria diagnosis.
