No vaccine has been more effective in reducing disease burden, especially in preventing child deaths, than measles-containing vaccine. The return on investment makes measles-containing vaccine one of the most cost-effective public health measures available. Exhaustive reviews of biological, technical, economic and programmatic evidence have concluded that measles can and should be eradicated, and by including rubella antigen in measles-containing vaccine, congenital rubella syndrome will also be eradicated.

Introduction: In 2015, the World Health Organization (WHO) developed guidelines for the management of sick young infants (SYIs) with possible serious bacterial infection (PSBI) where referral is not feasible. The Ponya Mtoto project was designed as an implementation research project to demonstrate how to adopt the WHO PSBI guidelines in the Kenyan context.

Ponya Mtoto Project Description: Between October 2017 and June 2021, Ponya Mtoto was implemented in 4 Kenyan counties with higher infant and newborn mortality rates than the national mean.

Possible severe bacterial infections (PSBI) is one of the three leading causes of newborn and young infant mortality globally that can be prevented by timely diagnosis and treatment using suitable antibiotics. High impact interventions such as use of out-patient injectable gentamicin and dispersible Amoxicillin with community-based follow up have been shown to reduce mortality in clinical trials. The objective of this study was to assess the health systems' preparedness and organizational gaps that may impact execution in providing care for newborns and sick young infants.

Aflatoxins are naturally occurring food toxins known to contaminate cereals with a carry-over effect in milk and meat products from farm animals raised on contaminated feed. In children, continuous consumption of aflatoxin-contaminated food is linked to immune suppression, vaccine interference and growth faltering while in adult populations, carcinogenesis in the liver has been established. We evaluate the main determinants of aflatoxin exposures among children recruited from primary schools in Makueni and Siaya Counties.

Aflatoxin exposure, malnutrition and growth impairment in children present significant public health problems in low- and middle-income countries. Recent epidemiology studies show that exposure to aflatoxins through dietary sources in early life contributes to growth retardation among children. However, the findings remain inconclusive due to limited comparative studies in high versus low aflatoxin exposure regions.

Background: Aflatoxins (AFs) are naturally occurring fungal metabolites produced by the species of fungi. The staple food grain, maize (), is highly susceptible to AF contamination. In Kenya, contamination of maize supplies by AFs is a recognized public health problem which has resulted in over 600 human deaths.

The majority of childhood deaths occur in low-income countries, with vaccine-preventable infections contributing greatly. Of the many possible environmental factors that could hamper a child's immune response, mycotoxins rank among the least studied in spite of the high exposure in vulnerable populations. Aflatoxin crosses the placenta, is secreted in breast milk and is consumed widely in weaning diets by children with developing organ systems.

Fumonisins (FNs), a group of mycotoxins produced mainly by species, are ubiquitous food contaminants, especially for maize. Fumonisin B (FB) caused severe toxicities in farm animals, induced kidney and liver tumours in rodents and is associated with many human adverse health effects, including oesophageal cancer. International Agency for Research on Cancer (IARC) categorizes FB as a possible human carcinogen (Group 2B).

There are compelling epidemiological, economic, and ethical arguments for setting a global measles eradication goal. The 6 chairpersons of Regional Verification Commissions for Measles and Rubella elimination advocate that the time for courageously accelerating efforts to ensure a world where no child dies of measles, is NOW!

Background: Neonatal mortality is a major health burden in Bungoma County with the rate estimated at 31 per 1000 live births and is above the national average of 22 per 1000. Nonetheless, out of the nine sub county hospitals, only two are fairly equipped with necessary infrastructure and skilled personnel to manage neonatal complications such as prematurity, neonatal sepsis, neonatal jaundice, birth asphyxia and respiratory distress syndrome. Additionally, with more than 50% of neonates delivered without skilled attendance, in below par hygiene environments such as home and on the roadsides, with non-existent community based referral system, the situation is made worse.

Background: The creation of a clinical network was proposed as a means to promote implementation of a set of recommended clinical practices targeting inpatient paediatric care in Kenya. The rationale for selecting a network as a strategy has been previously described. Here, we aim to describe network activities actually conducted over its first 2.

Background: Lack of detailed information about hospital activities, processes and outcomes hampers planning, performance monitoring and improvement in low-income countries (LIC). Clinical networks offer one means to advance methods for data collection and use, informing wider health system development in time, but are rare in LIC. We report baseline data from a new Clinical Information Network (CIN) in Kenya seeking to promote data-informed improvement and learning.

Africa has a significant burden of childhood disease, with relatively few skilled health care professionals. The African Paediatric Fellowship Programme was developed by the Department of Pediatrics and Child Health at the University of Cape Town to provide relevant training for African child health professionals, by Africans, within Africa. Trainees identified by partner academic institutions spend 6 months to 2 years training in the Department of Pediatrics and allied disciplines.
