The occurrence of a case of wild polio in a previously polio free area as presently in Syria, whether through importation, laboratory accident, or mutation of vaccine virus (VDPV), should be considered a public health emergency, that requires a rapid and high quality response as utmost priority
On October 6, 11 cases of Cholera were confirmed positive in one neighbourhood of the capital Sana’a. No confirmed cases have been reported in other locations in Yemen. UNICEF, together with WHO and Health authorities, have initiated a rapid response setting up a treatment centre as well as dispat...ching an investigation team to the affected neighbourhood. The source of infection was identified as water and commercial food contamination.

People living with HIV who have a low CD4 count are at a much higher risk of falling ill from TB infection than HIV negative people.
It is important to offer both HIV testing to TB patients and TB diagnosis in HIV patients. Early detection and effective treatment are essential to preventing TB...-associated deaths.
WHO and UNAIDS have strongly advised countries to ensure that HIV programmes integrate regular TB screening, preventive therapy and early treatment.

The updated List of Essential Diagnostics contains 46 general tests that can be used for routine patient care as well as for the detection and diagnosis of a wide array of disease conditions, and 69 tests intended for the detection, diagnosis and monitoring of specific diseases.
The List is divid...ed into two sections depending on the user and setting: one for community settings, which includes self-testing; and a second one for clinical laboratories, which can be general and specialized facilities.

The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on the clinical, epidemiological and virological chara...cteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)

This Interim Guidance outlines how key public health and social measures needed to reduce the risk of COVID-19 spread and the impact of the disease can be adapted for use in low capacity and humanitarian settings. The recommendations outlined here need to be adjusted to the scale of transmission, co...ntext and resources, in order to achieve the objective of managing COVID-19, namely to reduce transmission and facilitate the detection and management of infected and exposed individuals within the population. The Guidance is intended for humanitarian and development actors of all operational levels working with communities ocal authorities involved in COVID-19 preparedness and response operations in these settings, in support of national and local governments and plans. Additional considerations for support to residents of urban informal settlements and slums are available in Annex 1.

Systematic screening for TB disease is the systematic identification of people at risk for TB disease, in a predetermined target group, by assessing symptoms and using tests, examinations or other procedures that can be applied rapidly.
Systematic screening can benefit people who are at risk of get...ting TB, as early detection and start of treatment can improve their outcomes and reduce their costs. It can also benefit entire communities at higher risk for TB, by reducing the prevalence of TB disease and preventing future cases.

12 countries have a high TB estimated burden with an incidence rate more than 45 per 100 000 population They represent 88 of the cases in the Region
In 2019 the TB case detection gap in the Region was 52 500 cases
La meningitis es una enfermedad mortal y debilitante; golpea rápidamente, conlleva graves consecuencias sanitarias, económicas y sociales, y afecta a personas de todas las edades y en todos los países del mundo. La meningitis bacteriana puede provocar epidemias, ocasionar la muerte en 24 horas y ...dejar a una de cada cinco personas afectadas, con discapacidad permanente después de la infección. Muchos casos de meningitis y defunciones conexas son prevenibles mediante vacunación, pero los progresos para derrotar a la meningitis están rezagados respecto de otras enfermedades prevenibles mediante vacunación.

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.

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 M...UL_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.

The response to a cholera outbreak must focus on limiting mortality and reducing the spread of the disease. It should be comprehensive and multisectoral, including epidemiology, case management, water, sanitation and hygiene, logistics, community engagement and risk communication. All efforts must b...e well coordinated to ensure a rapid and effective response across sectors.
This document provides a framework for detecting and monitoring cholera outbreaks and organizing the response. It also includes a short section linking outbreak response to both preparedness and long-term prevention activities.
