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.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

The Strategy provides a high-level unifying framework to leverage existing capacities, address barriers and strengthen the use of genomic surveillance in the detection, monitoring and response to public health threats. Genomic surveillance is part of the broader surveillance and laboratory system, a...nd its implementation should reinforce end-to-end capacities including sample collection, diagnostics, data sharing and analysis. The strategy aims to facilitate the connectivity between different disease control programs and surveillance networks. This interoperability will strengthen the cross-cutting essential public health laboratory functions underpinning genomics holistically. The strategy articulates the overarching goal, objectives and strategic actions needed. These are dependent on commitments from countries, partners and WHO for their implementation.

Monkeypox is an emerging viral zoonosis with symptoms similar to those observed in smallpox patients, although less severe. Since the global eradication of smallpox in 1980, monkeypox has emerged as the most important orthopoxvirus in humans. The Advisory Committee on Variola Virus Research (ACVVR) ...which meets annually to oversee smallpox research has highlighted the importance of diagnostics that could distinguish between variola and other strains of orthopoxviruses, including monkeypox virus. The ACVVR encourages the positive effects of current smallpox research on all orthopoxviruses, specifically monkeypox, such as the development of diagnostic tools.

HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti...ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

The new WHO guidelines provide clinical management recommendations for four of the most widespread arboviruses affecting humans: dengue, chikungunya, Zika, and yellow fever.
An integrated approach is vital, as these four diseases often present with similar symptoms, especially in the early stages... of infection, and multiple arboviruses may circulate simultaneously in certain regions. This makes clinical differentiation challenging, particularly where diagnostic testing is not readily available.
This guideline is available in online format on the MAGICapp platform
