Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

The purpose of the WHO Manual for the Public Health Management of Chemical Incidents is to provide a comprehensive overview of the principles and roles of public health in the management of chemical incidents and emergencies. While this information is provided for each phase of the emergency cycle, ...including prevention, planning and preparedness, detection and alert, response and recovery, it is recognized that the management of chemical incidents and emergencies requires a multi-disciplinary and multi-sectoral approach and that the health sector may play an influencing, complementary or a leadership role at various stages of the management process. The target audience includes public health and environmental professionals, as well as any other person involved in the management of chemical incidents.
WHO and all those involved in the development of the publication hope that the publication will have wide application, especially in developing countries and countries with economies in transition, and that in the future the health sector will be better prepared to acknowledge and fulfill its roles and responsibilities in the management of chemical incidents and emergencies, thereby contributing to the prevention and mitigation of their health consequences.

Frontline health workers (FHWs) provide services directly to communities where they are most needed, especially in remote and rural areas. Many are community health workers and midwives, though they can also include local emergency responders/paramedics, pharmacists, nurses, and doctors who serve in... community clinics.
The growing burden of non-communicable diseases (NCDs) on low- and middle-income countries threatens many health systems that are already weakened. In many countries, health systems—and health workers—are not prepared to address the complex nature of NCDs. Health systems are often fragmented, and designed to respond to single episodes of care or long-term prevention and control of infectious diseases.1 Many countries also continue to face shortages and distribution challenges of trained and supported health workers. As most NCDs are multifactorial in origin and are detected later in their evolution, health systems face significant challenges to provide early detection as well as affordable, effective, and timely treatment, particularly in underserved communities.

Since the emergence of COVID 19 in December 2019, various public health responses measures have been implemented to control the pandemic. Among measures taken by the Africa CDC was the launch of PACT initiative to accelerate COVID 19 testing. Key to the initiative is the engagement of Community Heal...th Workers (CHWs) in risk communication and community engagement (RCCE), surveillance activities for early case identification, contacts tracing and in facilitating referrals for testing and continuum of care.
As of 31 May 2021, Through PACT support, over 17154 CHWs have been trained and locally deployed in 24 AU Member states. The PACT supported CHWs visited more than 2,568,654 households for community engagement activities, active case search and contact tracing, identified 1,618,601 Contacts, 710,167 COVID 19 suspect cases based on the standard case definition and facilitated referrals for 553053 (78%) suspect cases for testing. These efforts were crucial for early identification and isolation of cases in limiting further transmission.

Journal of Clinical TB and other Mycobacterial Diseases
uberculosis (TB) in the gastrointestinal tract or peritoneum is an uncommon condition in clinical practice. Its rarity, combined with its nonspecific presentations, makes this kind of extrapulmonary tuberculosis difficult to diagnose as it can... mimic other inflammatory or malignant conditions. Delays in treatment and frequent misdiagnosis can lead to hazardous complications. In countries like Ecuador where the disease is endemic, TB should always be considered in the differential diagnosis of a patients who present with nonspecific abdominal symptoms. In these scenarios, laparoscopy can be an invaluable tool when used with sufficiently high clinical awareness and adequate training.
Case presentation
We present the case of a 37-year-old female patient from Ecuador with a 1-year history of abdominal pain, nausea, intermittent vomits, night sweats, and weight loss. After clinical evaluation and a laparoscopic intervention, abdominal TB was detected and promptly treated. Antituberculosis chemotherapy was initiated, and the patient successfully reco
High clinical awareness is imperative when approaching abdominal TB due to its wide spectrum of clinical symptoms and its rarity. Early detection and prompt treatment are critical to minimize the possibility of hazardous complications.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.
