Records of heights and weights kept for more than 25 years for two neighbouring Gambian villages have been used to describe the pattern of growth. There was no secular trend in height. Children who died during the investigation were smaller and lighter than the survivors, but the interval between the last available dry-season measurement and death was not associated with the degree of deficit in height and weight. The presence of seasonal variation in the rates of growth in height and weight was shown, the lowest rates occurring during late rains (August to November). Height growth curves from the age of 5 to 23-25 years were fitted for 55 boys and 62 girls. The curves indicate that puberty is much delayed in Gambian adolescents in comparison to British and West Bengal data. The mean age at peak height velocity (PHV) was 16.3 and 13.8 years for boys and girls respectively. The corresponding velocities were 6.9 and 6.0 cm/yr. In girls but not in boys there was a significant negative correlation (-0.46) between the age at PHV and PHV itself. There was no significant correlation between the age at PHV and adult height. Comparison with British data suggests that growth patterns in the Gambian villages are characterized by the substantial deficits in both height and weight that develop in early life and which appear to persist without rectification into adulthood.

Trachoma, a neglected tropical disease caused by (Ct) serovars A-C, is the leading infectious cause of blindness worldwide. Africa bears the highest burden, accounting for over 86 % of global trachoma cases. We investigated Ct serovar A (SvA) and B (SvB) whole genome sequences prior to the induction of mass antibiotic drug administration in The Gambia.

Article Synopsis
- The study looks at how different family setups around the world affect how babies learn to talk and interact with people.
- Researchers focused on babies in The Gambia and the UK, using recordings to see how much and what kind of talk babies hear from their caregivers.
- They found that having many different caregivers in a household can change how babies learn to communicate with others.
Impact of the COVID-19 pandemic on a clinical trial of pneumococcal vaccine scheduling (PVS) in rural Gambia.

The COVID-19 pandemic represents an unprecedented challenge for clinical research. The Pneumococcal Vaccine Schedules (PVS) study is a non-inferiority, interventional trial in which infants resident in 68 geographic clusters are randomised to two different schedules for pneumococcal vaccination. From September 2019 onwards, all infants resident in the study area became eligible for trial enrolment at all Expanded Programme on Immunisation (EPI) clinics in the study area.

Article Synopsis
- The study aimed to investigate the prevalence of subclinical P. falciparum infections among school-aged children in The Gambia, using various diagnostic tools like microscopy, RDT, and PCR.
- The results showed that PCR (specifically varATS) detected a higher prevalence of 10.2% compared to only 2.9% by microscopy and 1.5% by RDT, highlighting the challenges of detecting low-density infections.
- Overall, the study indicated that conventional methods like microscopy and RDT have low sensitivity for identifying these subclinical infections, emphasizing the need for more sensitive diagnostic approaches.
The durability, functionality and acceptability of novel screened doors and windows after 4 years of use in a Gambian village: a cross-sectional survey.

Background: The World Health Organization recommends house screening as a tool for malaria control, yet evidence of the long-term durability, functionality and acceptability of this intervention is lacking. In this study, the sustainability and use of novel types of screened doors and windows was examined 4 years after installation in a Gambian village.
Methods: A survey of 31 houses, each with two screened doors and two screened windows, was conducted in the rainy season.
