Background: Rabies remains a major public health problem in low- and middle-income countries. However, human rabies deaths are rarely laboratory-confirmed or sequenced, especially in Africa. Five human rabies deaths from Tanzania and Kenya were investigated and the causative rabies viruses sequenced, with the aim of identifying implications for rabies control at individual, healthcare and societal levels.

Article Synopsis
  • Initial SARS-CoV-2 transmission peaked in densely populated areas of Kenya, gradually spreading to remote regions like Kajiado County, which struggle with inadequate healthcare.
  • In a study from March 2020 to March 2022, dry blood spots (DBS) were collected from patients to detect SARS-CoV-2 IgG antibodies using ELISA, revealing a seropositivity rate of 7.3%.
  • High seropositivity was found among the elderly and males, with the Mashuru and Meto health facilities showing the highest rates, indicating significant SARS-CoV-2 transmission in these underserved pastoralist communities.

Article Synopsis
  • Applied epidemiological models are key for understanding and managing disease outbreaks like SARS-CoV-2, but their effectiveness relies on local data, quick communication, and policymakers' willingness to utilize them.
  • A systematic review of 74 papers on SARS-CoV-2 modeling in Africa highlighted that most studies came from only a few countries, and very few used local data for calibration.
  • The findings underscore the importance of enhancing modeling capacity in Africa, as many studies focused on assessing control interventions and identified the transmission rate as a major source of uncertainty in model predictions.

Objectives: To assess outcomes of patients admitted to hospital with COVID-19 and to determine the predictors of mortality.

Setting: This study was conducted in six facilities, which included both government and privately run secondary and tertiary level facilities in the central and coastal regions of Kenya.

Participants: We enrolled 787 reverse transcriptase-PCR-confirmed SARS-CoV2-infected persons.

Background: In Africa, rabies causes an estimated 24,000 human deaths annually. Mass dog vaccinations coupled with timely post-exposure prophylaxis (PEP) for dog-bite patients are the main interventions to eliminate human rabies deaths. A well-informed healthcare workforce and the availability and accessibility of rabies biologicals at health facilities are critical in reducing rabies deaths.

Introduction: We estimated unit costs for COVID-19 case management for patients with asymptomatic, mild-to-moderate, severe and critical COVID-19 disease in Kenya.

Methods: We estimated per-day unit costs of COVID-19 case management for patients. We used a bottom-up approach to estimate full economic costs and adopted a health system perspective and patient episode of care as our time horizon.

Objectives: The objective of this study was to evaluate the performance of lateral flow immunoassay (LFA) against latex agglutination (LA), India ink and culture in point-of-care diagnosis of cryptococcus meningitis (CM). We conducted cross-sectional study among HIV-positive patients with suspected CM at Mbagathi Hospital, Nairobi, April-July 2017.

Results: Of 124 capillary blood and serum and 99 cerebrospinal fluid (CSF) samples, LFA and LA had a concurrence on serum of 94.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is associated with significant morbidity and mortality and has resultant important economic and societal costs underscoring the need for accurate surveillance. In recent years, prevalence rates reported in East Africa have been inconsistent, sparking controversy and raising concern.

Methods: We described antimicrobial susceptibility patterns of Staphylococcus aureus isolates cultured from patients within the Internal Medicine department of the largest public healthcare facility in East and Central Africa- the Kenyatta National Hospital (KNH) in Nairobi, Kenya.

Background: There is worldwide concern of rapidly increasing antimicrobial resistance (AMR). However, there is paucity of resistance surveillance data and updated antibiograms in Africa in general. This study was undertaken in Kenyatta National Hospital (KNH) -the largest public tertiary referral centre in East & Central Africa-to help bridge existing AMR knowledge and practice gaps.

Background: In 2014 the Kenya National Immunization Technical Advisory Group (KENITAG) was asked by the Ministry of Health to provide an evidence-based recommendation on whether the seasonal influenza vaccine should be introduced into the national immunization program (NIP).

Methods: We reviewed KENITAG manuals, reports and meeting minutes generated between June 2014 and June 2016 in order to describe the process KENITAG used in arriving at that recommendation and the challenges encountered.

Results: KENITAG developed a recommendation framework to identify critical, important and non-critical data elements that would guide deliberations on the subject.

Brucellosis is a common bacterial zoonotic infection but data on the prevalence among humans and animals is limited in Kenya. A cross-sectional survey was conducted in three counties practicing different livestock production systems to simultaneously assess the seroprevalence of, and risk factors for brucellosis among humans and their livestock (cattle, sheep, camels, and goats). A two-stage cluster sampling method with random selection of sublocations and households was conducted.

The World Health Organization (WHO) estimates that acute lower respiratory infections account for 4 million deaths per year. The rates are even higher in developing countries. Influenza, a virus causing respiratory infections, has widely been studied in developed countries.
