A Comparative Study of Asymptomatic Malaria in a Forest Rural and Depleted Forest Urban Setting during a Low Malaria Transmission and COVID-19 Pandemic Period.

The global malaria morbidity and mortality witnessed an increase from 2019 to 2020 partly due to disruptions in control programs' activities imposed by the COVID-19 pandemic. Therefore, there is still a significant burden of malaria in Cameroon which needs attention from all fronts to attain elimination goals. It is normally expected that a typical forest ecology that has undergone urbanization and subjected to high rates of ecological instabilities should also have a shift from characteristic perennial malaria transmission and a shift in the type of malaria endemicity plaguing such distorted forest ecology. In this observational comparative study, we randomly enrolled participants from rural and urban settings of a forest zone during a low malaria transmission period, which coincided with the onset of COVID-19 pandemic. An optimized structured questionnaire was employed, to collect socio-demographic data and associated risk factors. The CareStart™ Malaria HRP2 antigen test was performed on participants from both settings to determine the prevalence of community asymptomatic malaria. Of 307 participants, 188 (61.0%) were from the rural, while 119 (38.8%) from the urban community. The overall prevalence of asymptomatic malaria (27.0%) detected Plasmodium falciparum antigen in 83 participants. The urban community's prevalence was 4.2% (5 positives) while the rural community's was 41.5% (78 positives). In simple logistic regression models, rural forest community and farm around the house were statistically significant predictors of testing positive (coefficient 2.8, 95% CI 1.8-3.7, p value<0.001) and (coefficient 3.1, 95% CI 1.1-5.1, p value =0.003), respectively. In the multivariate model, the strongest predictor of testing positive was living in a rural community, with p < 0.001 and odds ratio of 10.9 (95% CI, 3.8-31.8). These results indicate that during a low transmission period, the prevalence of asymptomatic malaria differs between depleted urban and rural forested settings, suggesting a need for strategic target intervention for the control of asymptomatic malaria.

Factors associated with the uptake of intermittent preventive treatment of malaria in pregnancy in the Bamenda health districts, Cameroon.

INTRODUCTION: The World Health Organization (WHO) recommends that in malaria endemic areas with moderate to high transmission rates, pregnant women presenting for antenatal clinic (ANC) should receive at least three doses of intermittent preventive treatment in pregnancy (IPTp) for malaria between the 16th and 36th weeks of pregnancy at intervals of 4 weeks between doses. Several challenges remain in effective implementation of IPTp policy making the targeted coverage (80%) of the third doses of IPTp far from being achieved. The main objective of this study was to assess factors associated with the uptake of IPTp among pregnant women attending ANCs in the Bamenda Health District. METHODS: To reach our objectives, we carried out a cross-sectional study following informed consent with thirty-nine (39) healthcare workers (HCW) and four hundred (400) pregnant women who were either in the third trimester of pregnancy or had recently given birth in any of thirty-six (36) health facilities (HF) within the Bamenda Health District (BHD) from May to August 2014. All sites within the BHD were included. The participants were selected by simple random sampling. The principal research instrument was a structured and pre-tested questionnaire that was designed to capture socio-demographic data and data related to stage of pregnancy and knowledge about IPTp. Data was entered using Ms Excel and analysed using SPSS v20.0. Descriptive statistics (frequencies and percentages) was used to report findings. We used Chi-Square test to compare the categorical variables (Fischer's exact test was used in cases were conditions for Chi-Square test were not met). RESULTS: Uptake for at least one dose of IPTp was 95.3% (381/400) and 54.9% (209/400) had received all three doses, 15.5% (59/400) received only one dose and 4.8% (19/400) did not receive any of the doses of IPTp. Knowledge about IPTp was associated with an increase uptake of IPTp (P<0.001). All health care providers were knowledgeable about the importance and use of IPTp. However, 35.9% reported not receiving any training on IPTp. Among the health providers, 28.2% did not know when to start IPTp and 43.59% did not know when to stop IPTp. Out of all the health care providers, 30.77% complained of medication (sulfadoxine-Pyrimethamine) stock out and 84.62% practiced the policy of direct observed therapy. CONCLUSION: The uptake of the third dose of IPTp is poor in the Bamenda Health District and this may be attributed to medication stock out and inadequacy of routine trainings for the health providers. The good practice observed was that of direct observed therapy by HCWs. Patient knowledge about IPTp in our study was associated with better uptake of IPTp. Encouraging education of pregnant women on the importance of IPTp, providing routine training to HCWs and promoting direct observation of therapy may improve on IPTp uptake during pregnancy.
