horities using a reduced number of tests performed. The strategies are organized according to stages of transmission: (1) No cases reported or observed (Stage 0); (2) Imported cases (Stage 1); (3) Localized community transmission (Stage 2); (4) Large-scale community transmission (Stage 3). For each stage, the recommended approaches indicate which testing strategy to prioritize when there are severe limitations on laboratory testing. The document is based on the current epidemiology of COVID-19 and available molecular testing methods.

Laboratory Safety Handbook. Global edition
Las pruebas de cultivo y sensibilidad a fármacos son necesarias especialmente para los pacientes con riesgo de tuberculosis resistente a los medicamentos y para vigilar su respuesta al tratamiento. Si b
...
ien el cultivo y las pruebas de sensibilidad son cada vez más accesibles, la infraestructura para realizarlos es compleja y requiere equipos especializados y costosos. Con vistas a garantizar que el personal de laboratorio realice su trabajo de forma correcta y segura, este manual ofrece una guía práctica mediante textos sencillos e ilustraciones claras que ayudan a comprender los problemas de seguridad conexos. De ahí la importancia de su publicación en español para la red de laboratorios nacionales y supranacionales que apoya la Organización Panamericana de la Salud en la Región de las Américas.

The meeting was held from 26 to 27 March 2018 to review and discuss the following topics:
Advances and challenges in the use of fTLC, and new approaches to detecting mycolactone using monoclonal antibodies (mAbs).
The status of development of rapid diagnostic tests (RDTs) targeting the MUL
...
_3720 protein.
The role of PCR as a reference test, and hurdles in providing a confirmatory diagnosis and in establishing a quality assurance programme.
New molecular tools with potential for implementation at a level lower than in the national or regional reference laboratory, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA).
The need to harmonize and standardize methods for collection and preparation of specimens, so samples can be referred for diagnosis and stored for evaluation of new diagnostic tests in optimal conditions.
Barriers to accessing early diagnosis and treatment, including coordination at the programme level, and lack of adequate diagnostic tools.
Defining target product profiles (TPPs) to guide the development of new diagnostic tools that can be applied at different levels of the health system. Participants agreed that two TPPs would be developed to address the current gaps: (i) a rapid test for BU diagnosis at the primary health-care level; and (ii) a test for diagnosis of BU that can also assist in treatment monitoring and differential diagnosis at the district hospital or reference centre.

Since the World Health Organization (WHO) launched the Global Antimicrobial Resistance Surveillance System (GLASS) in 2015, there has been rapidly growing awareness among many African countries that they need to be doing more to combat antimicrobial resistance (AMR). The Africa Centres fo

r Disease Control and Prevention (CDC) was officially inaugurated in January 2017 and will support countries commencing surveillance for serious infectious disease threats in Africa, including resistance. Review of the recent WHO GLASS report suggests that, while certain nations do have some surveillance systems in place, very few countries in Africa currently conduct effective routine surveillance.

rrent low disease prevalence, the positive predictive 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.
