The STEPS survey of noncommunicable disease (NCD) risk factors in Zambia was carried out from July to September 2017. Zambia carried out Step 1, Step 2 and Step 3. Socio demographic and behavioural information was collected in Step 1. Physical measu...rements such as height, weight and blood pressure were collected in Step 2. Biochemical measurements were collected to assess blood glucose and cholesterol levels in Step 3. The survey was a population-based survey of adults aged 18-69. A multi-stage cluster sample design was used to produce representative data for that age range in Zambia. A total of 4,302 adults participated in the survey. The overall response rate was 74% for Step 1 and 2 and 65% for Step 3. A repeat survey is planned for 2022 if funds permit.

A Cost-Efficiency Analysis for the Kyrgyz Republi
Antibiotics have been useful in fighting infectious diseases in our country for decades, but because of the overuse and misuse of these agents, an increasing number of organisms are now resistant to them. The Philippines, like other Southeast Asian ...countries, has already been encountering the many challenges of antimicrobial resistance (AMR) which include increasing social and economic costs and rising patient mortality. Although considered a global threat, it is already an emerging local health concern which calls for an urgent collaboration among different sectors to provide solutions addressing this growing problem.

A new respiratory infectious disease, COVID-19, caused by a new coronavirus called SARS-CoV-2, emerged in early December 2019. Since then, the virus has spread to India and 106 other countries in Asia, Europe, North America, Africa, and Oceania. On... March 11, the World Health Organization (WHO) declared the outbreak a pandemic, which has since rapidly evolved. As an economic hub with substantial global connectivity and movement of people and goods, India is directly impacted by the COVID-19 pandemic. Although it is too early to gauge the full spectrum of the outbreak’s social and economic impacts, COVID-19 has already caused lockdowns in China, Korea, and in many countries in Europe, and in some states of India, suspension of schools and universities, disruption of food systems and other supply chains, as well as a slowdown in trade between India and rest of the world.

Despite being a curable and preventable disease, tuberculosis (TB) remains as one of the major challenges for health systems, globally. Every year, TB affects more than 10 million people and kills more than 1.4 million people. WHO’s Digital Health... for the End TB Strategy – an Agenda for Action outlines a conceptual framework in which advantageously positioned digital health solutions are matched to the most urgent needs of TB programmes. Video-supported treatment is a component of one of the four core functions of this framework, the Patient Care domain, and primarily supports the first pillar of the End TB Strategy. This quick guide provides information on the solutions available for asynchronous modes of video communication and how these can be of use to TB programmes.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors ...affect the potential for geographic spread and future dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

Preventing tuberculosis infection from progressing to tuberculosis disease is a crucial component of the goal to eliminate tuberculosis. When deciding on the use of tuberculosis preventive therapy among household contacts, policy makers regularly as...k questions, such as whether tuberculosis preventive therapy is effective, safe, and feasible in a programme setting and what it will cost. For contact management and tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis, studies from high-income and low-income countries have shown feasibility, safety, and effectiveness.
However, there is scarce information on the cost of tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis. In The Lancet Global Health, Peter Dodd and colleagues show that household contact management strategies are cost-effective even in low-income and middle-income countries, which has important policy implications for achieving the END TB Strategy goals.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is comm...on in rural tropical communities in West and Central Africa, where access to proper health care is limited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

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 that 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 major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reporte...d as an emerging disease in different regions of Africa [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment. Related to these interactions, the ..."attribute-to-highlight medbox">disease is confined in spatially limited areas called “foci”, which are located
in Sub-Saharan Africa, mainly in remote rural areas. The risk of contracting HAT is, therefore, determined by the possibility of contact of a human being with an infected tsetse fly. Epidemics of HAT were described at the beginning of the 20th century; intensive activities have been set up to confront the disease, and it was under control in the 1960s, with fewer than 5,000 cases reported in the whole continent.
