Chikungunya is a viral disease transmitted by Aedes mosquitoes to humans. The word ‘chikungunya’ means 'that which bends up', an allusion to the posture of the suffering patients. The most common clinical form associates fever, arthralgia and rash. Recovery is the usual outcome but chronic arthr...itis is not rare. Diagnostic tests are available but there is no antiviral treatment. The disease is notifiable at EU level.

Ade et al. BMC Health Services Research (2016) 16:5
Background: In the “Centre National Hospitalier de Pneumo-Phtisiologie” of Cotonou, Benin, little is known about
the characteristics of patients who have not attended their scheduled appointment, the results of tracing and the
possible b...enefits on improving treatment outcomes. This study aimed to determine the contribution of tracing
activities for those who missed scheduled appointments towards a successful treatment outcome.
Methods: A retrospective cohort study was carried out among all smear-positive pulmonary tuberculosis patients
treated between January and September 2013. Data on demographic and diagnostic characteristics and treatment
outcomes were accessed from tuberculosis registers and treatment cards. Information on those who missed their
scheduled appointments was collected from the tracing tuberculosis register. A univariate analysis was performed
to explore factors associated with missing a scheduled appointment

In response to the first cases of coronavirus disease 2019 (COVID-19) reported on the continent, many African Union Member States implemented large-scale public health and social measures (PHSM) rapidly. These measures were aimed at reducing transmission and the number of new cases being reported, p...rotecting the most vulnerable populations, and allowing time for countries to ramp up critical healthcare and diagnostic services. While these quick actions bought time for Member States, the negative socio-economic impacts are being felt widely, and countries are now exploring how best to ease these measures back while still managing the outbreak.

These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

Antimicrobial resistance (AMR) is a global human, animal, plant and environment health threat that needs to be addressed by every country. The impacts of AMR are wide-ranging in terms of human health, animal health, food security and safety, environmental effects on ecosystems and biodiversity, and ...socioeconomic development. Just like the climate crisis, AMR poses a significant threat to the delivery of the 2030 Agenda for Sustainable Development. The response to the AMR crisis has been spearheaded through the global action plan on antimicrobial resistance (GAP-AMR), developed by the World Health Organization (WHO) in 2015, in close collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (WOAH), and formally endorsed by the three organizations’ governing bodies and by the Political Declaration of the high-level meeting of the United Nations General Assembly on AMR in 2016. In 2022, the three organizations officially became the Quadripartite by welcoming the United Nations Environment Programme (UNEP) into the alliance “to accelerate coordination strategy on human, animal and ecosystem health”.
The aim of the GAP-AMR is to ensure the continuity of successful treatment with effective and safe medicines.
Its strategic objectives include:
• improving the awareness and understanding of AMR;
• strengthening the knowledge and evidence base through surveillance and research;
• reducing the incidence of infection through effective sanitation, hygiene and infection prevention measures; optimizing the use of antimicrobial medicines in human and animal health; and
• developing the economic case for sustainable investment that takes account of the needs of all countries and increasing investment in new medicines, diagnostic tools, vaccines and other interventions.
With the adoption of the GAP-AMR, countries agreed to develop national action plans (NAPs) aligned with the GAP-AMR to mainstream AMR interventions nationally. Individually, the Quadripartite took action to advance AMR interventions in their respective sectors. FAO adopted a resolution on AMR recognizing that it poses an increasingly serious threat to public health and sustainable food production, and developed an AMR action plan to support the resolution’s implementation. For its part, WOAH developed a strategy on AMR aligned with the GAP-AMR, acknowledging the importance of a One Health approach to AMR. Similarly, more recently, UNEP’s governing body, the United Nations Environment Assembly, recognized that AMR is a current and increasing threat and a challenge to global health, food security and the sustainable development of all countries, and welcomed the GAP-AMR and the NAPs developed in accordance with its five overarching strategic objectives

ajtmh.20-1538 Volume 104, 6. Mapping is a prerequisite for effective implementation of interventions against neglected tropical diseases (NTDs). Before the accelerated World Health Organization (WHO)/Regional Office for Africa (AFRO) NTD Mapping Project was initiated in 2014, mapping efforts in man...y countries were frequently carried out in an ad hoc and nonstandardized fashion. In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped. During its 3-year duration from January 2014 through the end of 2016, the project carried out mapping surveysfor one ormore NTDs in at least 2,500 districts in 37 African countries. At the end of 2016, most (90%) of the 4,851 districts had completed the WHO-required mapping surveys for the five targeted Preventive Chemotherapy (PC)-NTDs, and the impact of this accelerated WHO/AFRO NTD Mapping Project proved to be much greater than just the detailed mapping results themselves. Indeed, the AFRO Mapping
Project dramatically energized and empowered national NTD programs, attracted donor support for expanding these programs, and developed both a robust NTD mapping database and data portal. By clarifying the prevalence and burden
of NTDs, the project provided not only the metrics and technical framework for guiding and tracking program implementation and success but also the research opportunities for developing improved diagnostic and epidemiologic sampling tools for all 5 PC-NTDs—lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis, and trachoma.

Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

Tanzania, like other developing countries, is facing a higher burden of cardiovascular diseases (CVDs). The country is experiencing rapid growth of modifiable and intermediate risk factors that accelerate CVD mortality and morbidity rates. In rural and urban settings, cardiovascular risk factors suc...h as tobacco use, excessive alcohol consumption, unhealthy diet, hypertension, diabetes, hyperlipidemia, overweight, and obesity, are documented to be higher in this review. Increased urbanization, lifestyle changes, lack of awareness and rural to urban movement have been found to increase CVD risk factors in Tanzania. Despite the identification of modifiable risk factors for CVDs, there is still limited information on physical inactivity and eating habits among Tanzanian population that needs to be addressed. Conclusively, primary prevention, improved healthcare system, which include affordable health services, availability of trained health care providers, improved screening and diagnostic equipment, adequate guidelines, and essential drugs for CVDs are the key actions that need to be implemented for cost effective control and management of CVDs. Effective policy for control and management of CVDs should also properly be employed to ensure fruitful implementation of different interventions.

Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical man...ifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%-60%), followed by heart failure (25%-30%) and stroke (10%-15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly exi...sting as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.
