Transmission Dynamics of Monkeypox Virus in Nigeria during the Current COVID-19 Pandemic and Estimation of Effective Reproduction Number.

Monkeypox virus (MPXV) continues to pose severe threats to global public health, especially in non-endemic areas. Like all other regions, Africa faces potential public health crises due to the ongoing COVID-19 pandemic and other infectious disease outbreaks (such as Lassa fever and malaria) that have devastated the region and overwhelmed the healthcare systems. Owing to the recent surge in the MPXV and other infections, the COVID-19-control efforts could deteriorate and further worsen. This study discusses the potential emergencies of MPXV transmission during the current COVID-19 pandemic. We hypothesize some of the underlying drivers that possibly resulted in an increase in rodent-to-human interaction, such as the COVID-19 pandemic's impact and other human behavioral or environmental factors. Furthermore, we estimate the MPXV time-varying effective reproduction number (Rt) based on case notification in Nigeria. We find that Rt reached a peak in 2022 with a mean of 1.924 (95% CrI: 1.455, 2.485) and a median of 1.921 (95% CrI: 1.450, 2.482). We argue that the real-time monitoring of Rt is practical and can give public health authorities crucial data for circumstantial awareness and strategy recalibration. We also emphasize the need to improve awareness programs and the provision of adequate health care resources to suppress the outbreaks. These could also help to increase the reporting rate and, in turn, prevent large community transmission of the MPXV in Nigeria and beyond.

COVID-19 and Lassa fever in Nigeria: A deadly alliance?

As the COVID-19 pandemic poses serious threats to global public health, Nigeria faces a potential public health crisis owing to COVID-19 and other infectious diseases, such as Lassa fever (LF) and malaria. In this study, we discuss the possible determinants behind the decreased number of LF cases in Nigeria, which was likely due to the synergistic impact of the COVID-19 pandemic. During the COVID-19 pandemic, the epidemic curve of LF seems to have deviated from the general seasonal scale seen in past years, which could be due to underreporting of cases. In addition, partial compliance with nonpharmaceutical interventions, limited resources, or human behavior could be contributing factors. Thus, we suggest that better differentiation in terms of human and resource allocation between COVID-19 and LF could help curtail the transmission effectively.

Outpatient prevention counseling for malaria in northwest Nigeria: A single-centre descriptive cross-sectional study

To assess the proportion of caregivers of children and patients who received malaria prevention counseling from their healthcare provider at the time of outpatient malaria treatment. Methods: This was a descriptive cross-sectional study involving 353 randomly selected adult patients and caregivers of children attending the general and paediatric outpatient clinics of a Nigerian hospital. An interviewer-administered questionnaire was used to collect data on participants' sociodemographics and last malaria-episode characteristics. Chi square test and logistic regression analysis were used to determine factors associated with and predictors of receiving malaria-prevention counseling, respectively. Results: The mean age of the respondents was (33.6±9.6) years; they were predominantly females (257, 72.8%). Most had at least secondary-level education (304, 86.1%); the family size was mostly 1-6 persons in 202 (57.2%) respondents. They were treated mostly by doctors 256 (72.5%), but only 132 (37.4%) received malaria prevention counseling. Educational-level (χ
