Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

The preparedness strengthening team deployed to Ghana focused on specific objectives in order to assist the country in becoming as operationally prepared as possible to detect, investigate and report potential EVD cases effectively and safely and to mount an effective response to prevent a larger o...utbreak. To accomplish this goal, the team conducted “scoping” activities, stakeholder meetings, site visits and a “table-top” simulation exercise to determine what systems were in place and what aspects of preparedness could be strengthened.
It is organized in 10 components of the WHO consolidated checklist for EVD preparedness: 1) planning and coordination; 2) epidemiological and laboratory surveillance; 3) rapid response teams; 4) contact tracing; 5) points of entry; 6) laboratory; 7) case management; 8) infection prevention and control; 9) social mobilization and risk communication; 10) budget.

Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

This study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.
The objective of this concept note and the framework it outlines is the elimination of a group of CDs and the negative health effects they generate, which together create a tangible burden on affected individuals, their families and communities, and on health care systems throughout the Region. Thou...gh there is no unified consensus on the best measures to use for the public’s health and a nation’s epidemiologic situation, it is common for the disease burden to be measured by disease rates (incidence, prevalence, etc.), disease-specific death rates, comparative morbidity and mortality rates, geographic distribution, and disability-adjusted life years (DALYs). The current epidemiological situation, including data on disease rates or geographic distribution for the diseases in Table 1, is discussed below in Section 4. Hotez et al. (2008) were the first to review and compare the burden of DALYs in Latin America and the Caribbean—for NTDs, HIV/AIDS, malaria, and TB—as it existed about 10 years ago. Though the regional burden of TB, malaria, and neglected infectious diseases (NIDs) is somewhat less than it was 10 years ago, work (and schooling) continue to be lost to illness and premature death or disability, and the need for stepping up disease elimination efforts is evident in all communities living in vulnerable conditions....

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

Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

Policy brief, 24 July 2020
The COVID-19 pandemic has affected older people disproportionately, especially those living in long-term care facilities. In many countries, evidence shows that more than 40% of COVID-19 related deaths have been linked to long-term care facilities, with figures being as h...igh as 80% in some high-income countries. Concerted action is needed to mitigate the impact across all aspects of long-term care, including home- and community-based care, given that most users and providers of care are those who are vulnerable to severe COVID-19.
This policy brief provides 11 policy objectives and key action points to prevent and manage COVID-19 across long-term care. Its intended audience is policy makers and authorities (national, subnational and local) involved in the COVID-19 pandemic. The brief builds on currently available evidence on the measures taken to prevent, prepare for and respond to the COVID‑19 pandemic across long-term care services including care providers

Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.

The COVID-19 pandemic has put significant pressure on health systems all around the world. The drastic measures established to contain its spread are creating serious impediments to economic activity (including agrifood systems) and, consequently, to livelihoods and food security and nutrition.
Following the encouraging initial results of the pilot project, the Ministry of Health is committed to increasing access to MDR-TB diagnosis, treatment and care. An expansion plan for the programmatic management of drug-resistant TB has been developed and forms part of the Five Year National Strateg...ic Plan for TB Control, 2011-2015. The long-term goals of the MDR-TB expansion plan are threefold:
1. Diagnosis of MDR-TB in all groups of patients at risk for MDR-TB
2. Diagnosis of MDR-TB in all HIV-infected TB patients
3. MDR-TB treatment for all patients diagnosed with MDR-TB under WHO-endorsed treatment protocols

Epidemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world. The background factors of this threat are biological, environmental and lifestyle changes, among others. A potentially fatal combination of newly-discovered ...diseases, and the re-emergence of many long-established ones, demands urgent responses in all countries. Planning and preparation for epidemic prevention and control are essential. The purpose of this “Managing epidemics” manual is to provide expert guidance on those responses.

Policy Brief 2 June 2020
The COVID-19 pandemic is a health and human crisis threatening the food security and nutrition of millions of people around the world. Hundreds of millions of people were already suffering from hunger and malnutrition before the virus hit and, unless immediate action is tak...en, we could see a global food emergency. In the longer term, the combined effects of COVID-19 itself, as well as corresponding mitigation measures and the emerging global recession could, without large-scale coordinated action, disrupt the functioning of food systems. Such disruption can result in consequences for health and nutrition of a severity and scale unseen for more than half a century.

Health communication has proven to play a crucial role in addressing diseases such as dengue, Zika and chikungunya, for which there are no definitive or easily accessible vaccines. In this context, this discipline becomes a fundamental tool to promote the change behavior and promote preventive pract...ices that reduce the transmission of these diseases. By not having a definitive medical solution, accurate and timely information, effectively disseminated through educational campaigns, media and communication channels public health, can significantly influence individual and community actions to control the spread of these mosquito-borne viruses. The accumulated research around the threat of the aforementioned arboviral diseases brings together a series of recommendations around specific communication activities, such as disseminating timely and accurate information that integrates public health concerns and the needs of information of the population, especially vulnerable groups such as women of childbearing age, pregnant women and health workers.
