The WHO Health Emergencies Programme is currently monitoring 118 events in the region. This week’s main articles cover the following events:
Coronavirus disease 2019 (COVID-19) in Togo
Measles in Chad
Ebola virus disease (EVD) in Équateur Province, Democratic Republic of the Congo.
Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. I...n 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

Despite the considerable improvement in global health, millions of people still lack access to quality health services, including access to effective antimicrobial medicines, or are impoverished as a result of health spending. At the same time, antimicrobial resistance – a consequence of overuse a...nd misuse of antimicrobials – is increasingly a barrier to accessing effective care. The declining effectiveness of antibiotics is driven by multiple factors, many of which can be addressed through well functioning primary health care. However, primary health care has not always had much attention in national health sector responses to
antimicrobial resistance, which often focus on tertiary care, laboratory detection and surveillance. The three pillars of primary health care (community engagement, front-line health services including primary care and essential public health, and multisectoral action on wider health determinants) are central not just to Universal Health Coverage and the Sustainable Development Goals, but also to an effective response to antimicrobial resistance.

This interim guidance has been updated with advice on safe and appropriate home care for patients with coronavirus disease 2019 (COVID-19) and on the public health measures related to the management of their contacts.
The Government of Malawi, in fulfilling its primary role of protecting the lives of its vulnerable citizens during disasters and reducing their exposure to risk through preparedness, led the development of a National Coronavirus Disease (COVID-19) Preparedness and Response Plan.
As of 21 May 2020, 4.8 million confirmed cases of Coronavirus disease 2019 (COVID-19) have been reported globally. In South America, COVID-19 was first detected on 26 February 2020, when Brazil confirmed a case in São Paulo.
Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies

COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

MEDBOX Issue Brief 26. Cholera is an acute diarrhoeal infection caused by eating or drinking food or water that is contaminated with the
bacterium Vibrio cholerae. Cholera remains a global threat to public health and is an indicator of inequity and lack of
social development. Researchers have esti...mated that every year, there are 1.3 to 4.0 million cases of cholera, and 21
000 to 143 000 deaths worldwide due to the infection.
However, cholera remains a neglected and underreported disease. Many cases are not recorded due to limitations in
surveillance systems and fears of potential impact on trade or tourism.
Today cholera affects 47 countries across the globe. Almost every developing country faces cholera outbreaks or
the threat of cholera. Major ongoing outbreaks are being reported from Afghanistan, Bangladesh, Democratic
Republic of Congo, Ethiopia and Nigeria. Major outbreaks are currently in Syria and Haiti.
Therefore, MEDBOX decided to produce issue briefs on cholera and available resources in Arabic, English and
French.

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.
