The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Prevention, Assessment and Management
This guideline covers road-traffic-related air pollution and its links to ill health. It aims to improve air quality and so prevent a range of health conditions and deaths.
The NICE guideline "Hypertension in Adults: Diagnosis and Management" outlines recommendations for diagnosing and managing hypertension in adults over 18, including those with type 2 diabetes. It emphasizes accurate blood pressure measurement, recommending ambulatory or home monitoring to confirm di...agnosis. Cardiovascular risk and target organ damage should be assessed, considering age, lifestyle, and other conditions. Initial treatment focuses on lifestyle changes such as diet, exercise, and smoking cessation, with medication advised for stage 1 hypertension at high cardiovascular risk or stage 2 hypertension. Regular monitoring and treatment adjustments are recommended to maintain target blood pressure levels, with specific guidance for people over 80 and those with additional conditions like diabetes or kidney disease. The guideline aims to reduce risks of heart attack, stroke, and other complications, supporting evidence-based treatment decisions in clinical practice.
