The Global Burden of Disease Study (GBD) began 30 years ago with the goal of providing timely, valid and relevant assessments of critical health outcomes. Over this period, the GBD has become progressively more granular. The latest iteration provides assessments of thousands of outcomes for diseases..., injuries and risk factors in more than 200 countries and territories and at the subnational level in more than 20 countries. The GBD is now produced by an active collaboration of over 8,000 scientists and analysts from more than 150 countries. With each GBD iteration, the data, data processing and methods used for data synthesis have evolved, with the goal of enhancing transparency and comparability of measurements and communicating various sources of uncertainty. The GBD has many limitations, but it remains a dynamic, iterative and rigorous attempt to provide meaningful health measurement to a wide range of stakeholders.

In 2015, 5.9 million children under age five died (1). The major causes of child deaths globally are pneumonia, prematurity, intrapartum-related complications, neonatal sepsis, congenital anomalies, diarrhoea, injuries and malaria (2). Most of these diseases and conditions are at least partially cau...sed by the environment. It was estimated in 2012 that 26% of childhood deaths and 25% of the total disease burden in children under five could be prevented through the reduction of environmental risks such as air pollution, unsafe water, sanitation and inadequate hygiene or chemicals.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

UNAIDS report on the global AIDS epidemic shows that 2020 targets will not be met because of deeply unequal success; COVID-19 risks blowing HIV progress way off course. Missed targets have resulted in 3.5 million more HIV infections and 820 000 more AIDS-related deaths since 2015 than if the world w...as on track to meet the 2020 targets. In addition, the response could be set back further, by 10 years or more, if the COVID-19 pandemic results in severe disruptions to HIV services.

Chapter 1 of Frontier 2017: Emerging Issues of Environmental Concern
The COVID-19 pandemic demonstrated that
the world was not well prepared to respond
to an infectious disease threat of this magnitude. Countries across all socioeconomic and development categories have struggled
to implement effective national responses. Substantial amounts of additional investmen...t are required to support the development of country capacities to prevent, detect and respond to both existing and emerging
infectious disease threats. Prior research efforts have estimated that between US$96 and $204billion is required, globally, to
advance country-level health security capacities, with US$63–131billion needed over a 3-year period. Given the substantial costs
of ongoing COVID-19 response, estimated to
be over US$12.5trillion through 2024, and an estimated 12.1–22.7million excess deaths, globally, due to COVID-19 as of January 2022,
the importance and potential return on investment of such upfront investments in capacity building are more evident than ever before.

Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission

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.

Haiti, one of the poorest countries in the world, was devastated by an earthquake in 2010. The disaster uncovered the realities of a non-existent mental health care system with only ten psychiatrists nationwide. Attempts were made to assess the increased prevalence of mental illness, likely due to t...he trauma to which many were exposed. Several interventions were carried out with aims to integrate mental health into primary health care services. The interplay between socio-cultural beliefs and health (both mental and physical) in Haiti has been widely commented upon by both foreign aid and local caregivers. Observations frequently highlight barriers to the willingness of patients to seek care and to their acceptance of biomedicine over traditional Vodou beliefs. The perception of Haitian beliefs as barriers to the availability and acceptance of mental health care has intensified the difficulty in providing effective recommendations and interventions both before and after the earthquake. Argued in this review is the importance of considering the interactions between socio-cultural beliefs and mental health when developing models for the prevention, screening, classification and management of mental illness in Haiti. These interactions, especially relevant in mental health care and post-disaster contexts, need to be acknowledged in any healthcare setting. The successes and failures of Haiti’s situation provide an example for global consideration.

WHO recommends artemisinin-based combination therapies for treating uncomplicated malaria, alongside studies to monitor treatment effectiveness. Given the threat of antimalarial resistance, including partial resistance in several African countries, molecular tools are vital for tracking resistance. ...In 2015, WHO launched the External Quality Assessment scheme for nucleic acid amplification testing to ensure reliable lab results. Coordinated by WHO and operated by the United Kingdom National External Quality Assessment Service for Parasitology, the scheme provides quality-controlled specimens and reports to help improve testing accuracy. Experts recently discussed expanding the scheme to include antimalarial resistance markers.

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

Antimicrobial resistance (AMR) as a serious public health threat was globally acknowledged by WHO in 2015, through the launch of the Global Action Plan (GAP). With a limited number of new antibiotics in the developmental pipeline, many countries are in the process of establishing strategies for anti...microbial stewardship (AMS). Within each country, different healthcare challenges have
contributed to AMR. This has also shaped individual AMS strategies and policies. In South Africa (SA), there is a high burden of infectious diseases, mainly of bacterial origin. In addition, SA also has the highest number of people living with
human immunodeficiency virus (HIV) globally. According to the 2019 statistics, there are approximately 7.97 million people living with HIV in SA. Together with this, SA has the fourth largest tuberculosis population globally.
Other important challenges include poverty, malnutrition, a high burden of non-communicable diseases, and a dire shortage of trained healthcare professionals (e.g. clinicians, pharmacists, and nurses).
