Anaemia is a serious global public health problem that particularly affects young children, menstruating adolescent girls and women, and pregnant and postpartum women. It is a condition in which the number of red blood cells or the haemoglobin concentration within them is lower than normal, affectin...g the blood’s ability to carry oxygen to the body’s tissues.
To reliably monitor the prevalence of anaemia at a population level, it is vital to measure the haemoglobin concentration in an accurate and precise way. In large-scale surveys, however, haemoglobin is most commonly measured using single-drop capillary blood specimens in point-of-care devices. Emerging evidence suggests that the use of single-drop capillary blood can introduce random and/or systematic errors, which may lead to inaccurate estimates, complicating effective anaemia programming.
This technical brief describes the current best practices for haemoglobin measurement, providing guidance to help plan or implement field surveys to assess anaemia at a population level. Continuing work to review emerging evidence is led by members of the WHO-UNICEF Technical Expert Advisory group on nutrition Monitoring (TEAM).

In the face of rapid increases in the number of hospitalizations due to COVID-19 in Latin America and the Caribbean, coupled with shortages of human and material resources, including medical equipment and gases, there is a need to redesign models of care in the Region to optimize available resources... and ensure that more patients receive the quantity and quality of oxygen they need. Oxygen is included in the World Health Organization’s list of essential medicines and is used to care for patients at all levels of integrated health services networks. The efficacy of oxygen use in the treatment of patients with respiratory conditions caused by COVID-19 has been demonstrated, but there is great opportunity to improve the effectiveness of its use if it is used in a rational, sustainable, and safe way. Bearing in mind that the efficacy of a health technology is measured by its benefit under actual conditions of use, practical actions can be taken to improve the use of medical oxygen and avoid oxygen shortages. A drug is considered to be used rationally when patients receive it according to their clinical needs, in doses appropriate to their individual needs, for an appropriate period, and at a low cost to them and their community. By providing instruction on the rational use of oxygen and promoting it, negative repercussions can be avoided, such as loss of efficacy as a result of activities related to oxygen storage, distribution, and administration. Rational use of oxygen also involves controlling waste due to leaks in storage and distribution systems, use of gas at incorrect pressures, use of incorrectly adjusted flowmeters, and disconnections, among other problems. Another aspect to consider is the provision of adequate technical support for all oxygen production systems, in terms of maintenance and calibration, availability of electrical energy, and specific knowledge about these systems. For these reasons, a set of guidelines has been put together for the development of an efficient management system to deal with situations of oxygen scarcity, both now and in the future.

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.
