The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

ECDC Technical Report
In line with ECDC’s recommendations provided in the ’Risk Assessment of HTLV-1/2 transmission by tissue/cell transplantation’ dated 14 March 2012, this Directive replaces the term ‘incidence’ with ‘prevalence’ in the description of endemic areas of HTLV-1/2 i...nfection. According to the new requirements ‘HTLV-1 antibody testing must be performed for donors living in, or originating from high-prevalence areas or with sexual partners originating from those areas or where the donor’s parents originate from those areas’ and this applies to both donors of non-reproductive tissues and cells and reproductive cells.
ECDC contracted experts from the Institut Pasteur in Paris to systematically review the published evidence on the distribution of HTLV-1 infection prevalence throughout the world and to identify high-prevalence countries and areas.

The guidelines are to be used to guide the management of adults with lower respiratory tract infection (LRTI). As will be seen in the following text, this diagnosis, and the other clinical syndromes within this grouping, can be difficult to make accurately. In the absence of agreed definitions of th...ese syndromes these guidelines are to be used when, in the opinion of a clinician, an LRTI syndrome is present. The following are put forward as def-initions to guide the clinician, but it will be seen in the ensuingtext that some of these labels will always be inaccurate. These definitions are pragmatic and based on a synthesis of available studies. They are primarily meant to be simple to apply in clinical practice, and this might be at the expense of scientific accuracy. These definitions are not mutually exclusive, with lower respiratory tract infection being an umbrella term that includes all others, which can also be used for cases that cannot be classified into one of the other groups. No new evidence has been identified that would lead to a change in the clinical definitions,which are therefore unchanged from the 2005 publication.

The planning and implementation of intervention measures against schistosomiasis, particularly mass administration, require knowledge of the current status of the infection. This is important for monitoring the impact of the interve...ntion on disease indicators such as a decline in infection prevalence, intensity of infection, and urogenital morbidities. Following repeated rounds of mass treatment in northwestern Tanzania, the epidemiology of urogenital schistosomiasis has changed; thus, for the effective planning and allocation of resources, it is important to understand the current status of the disease in the targeted groups

Intestinal schistosomiasis is highly endemic in Tanzania and mass drug administration (MDA) using
praziquantel is the mainstay of the control program. However, the MDA program covers only school aged children
and does not include neither adult individuals nor... other public health measures. The Ijinga schistosomiasis project
examines the impact of an intensified treatment protocol with praziquantel MDA in combination with additional
public health interventions. It aims to investigate the feasibility of eliminating intestinal schistosomiasis in a highly
endemic African setting using an integrated community-based approach.
