This document outlines minimum requirements of laboratory testing for COVID-19 and link laboratory testing with surveillance and contact tracing to guide the outbreak response by national health authorities using a reduced number of tests performed. The strategies are organized according to stages o...f 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.

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.

EU/EEA Member States and the UK have increased their laboratory capacity tremendously over the past 11 months as the majority of the Member States reported sufficient testing capacity until March 2021.
Many countries are adding rapid antigen detection tests (RADT) to their ...testing strategies in order to reduce pressure on RT-PCR testing.
Some Member States have already included RADT in their case definition.
The main bottlenecks, such as shortages of laboratory consumables and human resources, as well as sample storing facilities, continue to exist and may affect the overall laboratory response to COVID-19.

As of October 2017, the global database comprised almost 30 000 records, including results from bioassays to measure phenotypic resistance, and biochemical and molecular tests for resistance mechanisms. The current report presents an overview of data on malaria vector resistance for 2010 to 2016. It... aims to provide the baseline for subsequent status updates and to identify any temporal trends. An online mapping tool called Malaria Threats Map allows further interactive exploration of available data.

These guidelines provide new and updated recommendations on the use of point-of-care testing in children under 18 months of age and point-of-care tests to monitor treatment in people living with HIV; the treatment monitoring algorithm; and timing of antiretroviral therapy (ART) among people living w...ith HIV who are being treated for tuberculosis.
New recommendations launched today outline key new actions that countries can take to improve the delivery of HIV testing, treatment and care services by providing greater options for differentiated approaches such as, supporting HIV treatment start in the community, ensuring that children are diagnosed and treated early, and that viral load treatment monitoring is more accessible, focused and triggers clinical action

The Ministry of Public Health in the Democratic Republic of the Congo (DRC) has reported the country’s first case of COVID-19. Health authorities said tests found that a Congolese national, who had recently returned to Kinshasa from his residence in France had tested positive for the virus.
Self-care interventions are evidence-based, quality drugs, devices, diagnostics and/or digital products which can be provided fully or partially outside of formal health services and can be used with or without the direct supervision of health care personnel.
Where HPV tests are available as part o...f the national programme, HPV self-sampling offers an additional option to improve cervical cancer screening coverage.
Self-sampling can help reach a global target of 70% coverage of screening by 2030. Women may feel more comfortable taking their own samples, rather than going to see a health worker for cervical cancer screening.

The updates are based on evidence emerging from the: Ongoing monitoring of the disease. Protection that the population already developed against COVID-19 through previous infection or vaccination. Epidemiological situation, availability of diagnostic tests and access to therapeutic options.
Asthma has a significant impact on people of all ages, particularly children. A lack of universally accepted case definition and confirmatory tests and a poor understanding of major risks interfere with a global response. We aimed to provide global estimates of asthma prevalence and cases in 2019 ac...ross four main epidemiological case definitions – current wheezing, ever wheezing, current asthma, and ever asthma. We further investigated major associated factors to determine regional and national distributions of prevalence and cases for current wheezing and ever asthma.

These new approaches include use of selective chemotherapy, Rapid Diagnostic Tests (RDTs), Zinc for treatment of cholera in children and complementary use of OCV
Diagnostic performance, cost-effectiveness, ease of performance, rapidity and in-field applicability of tests for Soil-transmitted helminth infections.
This document updates recommendations for HIV testing by laboratories in the United States and offers approaches for reporting test results to persons ordering HIV tests and to public health authorities. The recommended algorithm is a sequence of tests used in combination to improve the accuracy of ...the laboratory diagnosis of HIV based on testing of serum or plasma specimens. The updated recommendations also include tests for HIV antigens and HIV nucleic acid because studies from populations at high risk for HIV demonstrate that antibody testing alone might miss a considerable percentage of HIV infections detectable by virologic tests

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.

It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.
