In doing so, it provides an expanded exploration of the themes beyond what is provided in the Action Plan itself and reflects the topical issues and considerations that shaped its design, including those issues identified in the World Health Assembly Resolution WHA74.14 to protect, safeguard and invest in the health and care workforce (1). The importance of these themes was again emphasized at the Seventy-fifth World Health Assembly, when Resolution WHA75.17: Human resources for health was co-sponsored by over 100 Member States, calling for the adoption and implementation of the Working for Health 2022–2030 Action Plan and utilization of the related Global Health and Care Worker Compact

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.

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 WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological

placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca

n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Further, the country has successfully eliminated infectious diseases such as polio, measles, and maternal and neonatal tetanus. There is full political commitment to reducing the incidence of tuberculosis (TB) by 80% and the number of deaths due to TB by 90% by 2030. The country has made great progress in the context of the pandemic, having established numerous quarantine facilities/isolation centres; trained health-care workers; streamlined the procurement and supply of medicines, consumables, personal protective equipment and other equipment; and strengthened the capacity in critical care across secondary and tertiary health care, to better respond to future pandemics and other disaster situations.

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....

n children still die each year under the age of 5, and nearly half of those are newborns less than a month old. Worse still, the global maternal mortality ratio is going in the wrong direction.
A Decade of Progress and Action for the Future will examine the tenacity and innovation that helped us make gains, the lessons learned through monitoring, country-led adaptation and leadership, analysis, and reflection, as well as the approaches we must take to reinvigorate the momentum and global commitment to improving maternal and child survival. Increasing coverage, strengthening the quality of care, and enhancing equity will be tantamount to our global progress.
