SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

The meningitis road map has been designated as a flagship global strategy of the WHO’s Thirteenth General Programme of Work, 2019–2023 and is an essential component in achieving universal health coverage.
The road map will reinforce and combine with wider initiatives, such as those aimed at s...trengthening primary health care and health systems, increasing immunization coverage, improving global health security, fighting antimicrobial resistance and advocating for the rights of persons with disabilities. It will complement other global control strategies, such as those addressing sepsis, pneumonia, tuberculosis and HIV. Implementation will be a challenge for all countries across the world, but especially in resource-poor settings where the burden of meningitis is greatest. The targets for the visionary and strategic goals will be adapted to regional and local contexts.

La méningite est mortelle et débilitante ; elle frappe brutalement ; elle a de graves conséquences sanitaires, économiques et sociales et touche tous les âges de la vie dans tous les pays du monde. La méningite bactérienne peut être à l’origine d’épidémies, entraîner la mort dans les... 24 heures et un patient sur cinq peut rester handicapé à vie à la suite d’une infection. La plupart des cas et des décès dus à la méningite pourraient être évités par la vaccination mais les progrès obtenus pour la vaincre sont bien moins rapides que ceux réalisés contre d’autres maladies à prévention vaccinale.

Objetivos.
Estimar la carga de tuberculosis (TB) en menores de 15 años y describir las características clínico, epidemiológicas y los resultados del tratamiento antituberculoso en Ecuador.
Métodos.
Se realizó un estudio retrospectivo utilizando los datos del programa nacional de TB de los... años 2015 y 2016. Se estimaron la tasa y el porcentaje de casos de TB infantil y se describieron las características de la enfermedad y el resultado del tratamiento según las categorías de edad: 0-4, 5-9 y 10-14 años.
Resultados.
De los 10 991 casos de TB diagnosticados, 223 (2,03%) fueron menores de 15 años; según la región del país esta carga varió entre 0 y 5,5%. De los 223 casos, en 213 se había registrado el resultado del tratamiento y fueron incluidos en el estudio; 78 (37%) eran menores de 5 años y en 147 (69%) no hubo registro de la investigación de contactos. Sesenta y cinco (68%) de los adolescentes y 40 (51%) de los menores de 5 años tenían diagnóstico de TB pulmonar. La prevalencia de VIH fue 11,5% en los menores 5 años y 6,3% en el grupo de 10-14 años. El tratamiento fue satisfactorio en el 93% de los casos, (curación, 36,6%, tratamiento terminado, 56,8%).
Conclusiones:
Ecuador presenta un alto porcentaje de subdiagnóstico de TB infantil y una carga menor a la esperada, principalmente en menores de 5 años. La alta prevalencia de VIH y la falta de sistematización adecuada de la investigación de contactos en los adolescentes revelan la necesidad de considerar estrategias centradas en la familia y que involucren la capacitación del personal de salud en el manejo del paciente pediátrico centrándose en las necesidades específicas de cada población.

Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the na...tional demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0.8% of the population) and a 3.4% incidence of cryptococcosis in hospitals, it is estimated that 459 patients per year develop cryptococcosis. For pneumocystosis, it is suggested that 1013 new cases occur every year. Taking into account the local TB frequency (population prevalence at 0.052%), we estimate the prevalence of chronic pulmonary aspergillosis at 1120 cases. Severe forms of asthma with fungal sensitization and allergic bronchopulmonary aspergillosis are estimated to affect 7429 and 5628 cases, respectively. Vulvovaginal candidiasis may affect 179,000 women, and almost 1,000,000 children may suffer from tinea capitis. Globally, we estimate that roughly 1.4 million people in Burkina Faso (7.51% of the population) suffer from a serious fungal infection. These data should be used to drive future epidemiological studies, diagnostic approaches, and therapeutic strategies.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

Les infections au SRAS-CoV-2 chez les enfants et les adolescents provoquent une maladie moins grave et moins de décès que chez les adultes. Bien qu'une évolution moins grave de l'infection soit un résultat positif, on s'inquiète du fait que des symptômes légers aient pu conduire à moins de t...ests, ce qui a entraîné un nombre moins important de cas identifiés de COVID-19 chez les enfants. Si les enfants présentant des symptômes légers ou inexistants transmettent la maladie, ils peuvent agir comme des vecteurs de transmission au sein de leur communauté. Il est essentiel de comprendre les symptômes, l'infectivité et les modes de transmission du SRAS-CoV-2 chez les enfants et les adolescents pour développer, adapter et améliorer les mesures de contrôle du COVID-19 à tous les âges. Ce document est un résumé des connaissances actuelles concernant l'acquisition et la transmission de l'infection par le SRAS-CoV-2 et les symptômes de la maladie COVID-19 chez les enfants et les adolescents. Il vise à éclairer les décisions, en fonction des contextes locaux, sur la meilleure façon de maintenir ouvertes les écoles, les jardins d'enfants et les crèches et sur les conseils à appliquer en matière de mixité intergénérationnelle.

Emerging evidence from the COVID-19 crisis in 2020 shows school closures, disruptions in essential services and rising... poverty contributed to girls’ increased risk of female genital mutilation (FGM). School closures limited the monitoring and reporting of cases of FGM. Rising household monetary poverty may have contributed to families adopting negative coping mechanisms, including having girls undergo FGM as a precursor to marriage to reduce household costs. A report from the United Nations Population Fund (UNFPA) estimates 2 million additional cases of FGM by 2030 due to the pandemic.

Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.
