In the Region of the Americas, as of 24 February 2023 (16:00 EST), there are a total of 58,578 confirmed cases of mpox (Table 1, Figure 2) were reported from 31 countries and territories, including 76 deaths in: United States of America (34), Brazil (15), Peru (15), Mexico (4), Chile (2), Ecuador (3...), Argentina (2), and Cuba (1), reported from 31 (Table 1, Annex 1, Figure 3). In the last 4 weeks (28 January – 24 February 2023), 607 additional mpox cases were reported from 16 countries and territories, including 9 deaths in Ecuador (1) and United States (8). Eight countries in the Region account for 97% of confirmed cases: United States of America, Brazil, Colombia, Mexico, Peru, Canada, Chile, and Argentina – listed by total number of cases in decrease order (Figure 4). The number of new weekly reported cases in EW 7 compared to EW 6 of 2023 (% variation) decreased by 55%.

En décembre 2022, la République démocratique du Congo a déclaré une flambée nationale de variole simienne. Un système de gestion des incidents est en place depuis février 2023, compte tenu du nombre croissant de cas signalés. Depuis septembre 2023, l’épidémie de variole simienne continu...e de se propager dans la province du Sud-Kivu, ainsi que, plus récemment, dans la province voisine du Nord-Kivu, du fait de la transmission par contact sexuel

BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

Asthma is the most common chronic disease in children, imposing a consistent burden on health system. In recent years, prevalence of asthma symptoms became globally increased in children and adolescents, particularly in Low-Middle Income Countries (LMICs). Host (genetics, atopy) and environmental fa...ctors (microbial exposure, exposure to passive smoking and air pollution), seemed to contribute to this trend. The increased prevalence observed in metropolitan areas with respect to rural ones and, overall, in industrialized countries, highlighted the role of air pollution in asthma inception. Asthma accounts for 1.1% of the overall global estimate of “Disability-adjusted life years” (DALYs)/100,000 for all causes. Mortality in children is low and it decreased across Europe over recent years. Children from LMICs particularly suffer a disproportionately higher burden in terms of morbidity and mortality. Global asthma-related costs are high and are usually are classified into direct, indirect and intangible costs. Direct costs account for 50–80% of the total costs. Asthma is one of the main causes of hospitalization which are particularly common in children aged < 5 years with a prevalence that has been increased during the last two decades, mostly in LMICs. Indirect costs are usually higher than in older patients, including both school and work-related losses. Intangible costs are unquantifiable, since they are related to impairment of quality of life, limitation of physical activities and study performance. The implementation of strategies aimed at early detect asthma thus providing access to the proper treatment has been shown to effectively reduce the burden of the disease.

The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”.
In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definition of wheeze was assessed. Predictors of a correct ...definition were determined and the potential impact of incorrect answers on prevalence estimates from the survey was assessed.
Current wheeze was reported by 13.2% of children. Overall, 83.5% of parents correctly identified “whistling or squeaking” as the definition of wheeze; the proportion was higher for parents reporting wheezy children (90.4%). Frequent attacks of reported wheeze (adjusted odds ratio (OR) 3.0), maternal history of asthma (OR 1.5) and maternal education (OR 1.5) were significantly associated with a correct answer, while the converse was found for South Asian ethnicity (OR 0.6), first language not English (OR 0.6) and living in a deprived neighbourhood (OR 0.6).
In summary, the present study showed that misunderstanding could lead to an important bias in assessing the prevalence of wheeze, resulting in an underestimation in children from South Asian and deprived family backgrounds. Prevalence estimates for the most severe categories of wheeze might be less affected by this bias and questionnaire surveys on wheeze should incorporate measures of parents' understanding of the term wheeze.

There has been a global outbreak of mpox since 2022; this outbreak has been caused by the strain of mpox virus called Clade 2 and has affected around 116 countries worldwide. The current surge in cases is being driven by the rapid spread of a different strain – Clade 1b – which is predominantly ...affecting countries across the African region, particularly DRC, Burundi, Kenya, Uganda and Rwanda [1]. The guidance in this document applies to both Clades of mpox. WHO publishes a dashboard of updated cases globally here. Different Clades and Sub-Clades of mpox behave slightly differently to each other; WHO is monitoring for any significant differences between the Clades, including transmission routes. This guidance will be updated as more information becomes available on this issue.
