Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Promoting health and preventing disease is a critical component of the effort required to achieve Universal Health Coverage (UHC). to date, efforts to achieve UHC have focused mostly on strengthening health systems and their capacities to provide curative care. However, experience from the COVID-19 ...pandemic has reaffirmed the need for resilient health systems, emphasizing primary health care, including preventive and promotive health and well-being.
Emerging from the eye of the storm as the global health lead agency during the pandemic, WHO is equipped with the required insights and actions for a holistic approach to “building back fairer and better” after COVID-19.
The Healthier Populations (UHP) Cluster in the African Region is designed to support Pillar 3 of WHO’s 13th Global Programme of Work (GPW13) which aims to make 1 billion people healthier by reducing health inequities, preventing diseases and injuries, addressing health determinants, and promoting partnerships for collaborative actions amongst all stakeholders.

This report presents three scenarios on the impact of COVID-19 in Africa using economic growth forecasts, mortality and efforts to ameliorate impact through social grants. Likely effects are examined on per capita income, poverty and the attainment of selected Sustainable Development Goals targets. ...Africa’s development trajectory has suffered a severe setback, with extreme poverty rising in all the scenarios. The pandemic threatens Africa in several ways, and the report provides policy recommendations to reduce vulnerability and strengthen resilience.

In Kenya, the bacterial infections that contribute most to human disease are often those in which re-‐sistance is most evident. Examples are multidrug-‐resistant enteric bacterial pathogens such as typhoid, ... diarrhoeagenic Escherichia coli and invasive non-‐typhi salmonella, penicillin-‐resistant Streptococcus pneu-‐moniae, vancomycin-‐resistant enterococci, methicillin-‐resistant Staphylococcus aureus and multidrug-‐re-‐sistant Mycobacterium tuberculosis. Resistance to medicines commonly used to treat malaria is of particu-‐lar concern, as is the emerging resistance to anti-‐HIV drugs. Often, more expensive medicines are required to treat these infections, and this becomes a major challenge in resource-‐poor settings.

Excessive consumption of salt (more than 5 g per day) raises blood pressure, a major risk factor for cardiovascular diseases such as heart disease and stroke, and is the leading cause of death in the WHO European Region. Many countries in the Region have initiated national salt reduction strategies,... including public awareness campaigns, reformulation, and front-of-pack nutrition labelling. However, despite ongoing efforts, surveillance data indicate that salt intake still far exceeds the limits recommended by WHO to protect health.

India contributes to 16% of the global maternal deaths and around 27% of global newborn deaths. Reducing the burden of maternal and newborn mortality and morbidity in urban poor settings today requires an expansion of effective Maternal and Newborn Health (MNH) care services and lowering the barrier...s to the use of such services, especially availability and accessibility.
For designing sensitive, responsive and relevant urban health policy and action, it is important for planners and programme managers to understand the context with regard to current systems and mechanisms, potential organisations and best practices.
In order to adres this need, Save the Children’s Saving Newborn Lives programme commissioned a study that reviewed the literature and looked at available secondary data on MNH in urban poor settings.

The attainment of Zambia’s goal of being a prosperous and middle-income country by 2030 as stipulated in its Vision 2030 is dependent on among others, a healthy and productive population. Therefore, the Government of the Republic of Zambia (GRZ) has prioritized health as a key socio-economic inves...tment in the Seventh National Development Plan 2017-2021. The government is also committed to achieving the targets under the health goal number three and other health related targets under other goals of the 2030 Sustainable Development agenda. Despite progress which has been made in improving the health of Zambians, the country still faces a high burden of communicable diseases and a growing burden of non-communicable diseases. Structural and social deprivation including poverty, inequalities and marginalisation also remain major threats to health. In order to effectively address all the social determinants of health, all sectors should take into account health and well-being as a key element of policy development.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.
