Wiping out Trachoma from Nepal – How Nepal eliminated trachoma as a public health problem
WHO - 2018
Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
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 reported as an emerging disease in different regions of Af...rica [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 WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...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).

Burden of T. solium: Neurocysticercosis is a disease induced by T. solium larvae penetrating human tissues, especially the nervous system. Neurocysticercosis burdens economies, societies and individuals because of the impact of epilepsy on wages, health costs and social stigmatization of sufferers. ...Health systems are also burdened as treatments must be tailored to individual needs.

Schistosomiasis is widely recognized as a disease that is socially determined. An
understanding of the social and behavioural factors linked to disease transmission and
control should play a vital role in designing policies and strategies for schistosomiasis
prevention and control. To this must b...e added the awareness that schistosomiasis is
also a disease of poverty. It still survives in poverty-stricken, remote areas where there
is little or no safe water or sanitation, and health care is scarce or non-existent. For
a variety of complex reasons, many of which are addressed in this book, the disease
is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural
China. This concern for human behaviour in an environment of poverty echoes the
concerns of the new research priority for “diseases of poverty” identified by the
Special Programme for Research & Training in Tropical Diseases.

Rabies is entirely preventable, and vaccines, medicines, tools and technologies have long been available to prevent people from dying of dog-mediated rabies. Nevertheless, rabies still kills about 60 000 people a year, of whom over 40% are children under 15, mainly in rural areas of economically dis...advantaged countries in Africa and Asia. Of all human cases, up to 99% are acquired from the bite of an infected dog.

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 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.

Cervical cancer continues to be a significant public health problem and a major cause of premature mortality among women, disproportionately affecting the socioeconomically disadvantaged population in low- and middle-income countries (LMICs). In the absence of implementing the known evidence-based, ...cost-effective interventions, the number of deaths per year is projected to reach approximately 416 000 globally in 2035. It was estimated in 2020 that 32% of incident cervical cancer cases and 34% of cervical cancer deaths in the world occurred in the 11 Member States of the WHO South-East Asia (SEA) Region. In 2020, 190 874 new cases and 116 015 deaths were estimated due to cervical cancer, which is the third commonest cancer in the Region

Les conflits et les guerres ont des effets catastrophiques sur la santé et le bien-être des nations, et ils ont considérablement évolué au cours des dernières décennies. Avec la forte augmentation des crises humanitaires, y compris de la violence urbaine, de plus en plus de gens sont touchés... pendant des périodes plus longues par des interruptions des services élémentaires, devenues une triste réalité.
Les interventions sanitaires et les approches novatrices face aux défis que posent les
crises humanitaires peuvent sauver des vies et atténuer les conséquences des conflits
pour les civils.
Les équipes médicales qui interviennent lors de conflits armés et dans d’autres
environnements dangereux sont fréquemment confrontées à de graves menaces pour
leur sécurité et leur sûreté. Elles doivent surmonter ces difficultés pour avoir accès
aux patients, d’autant plus qu’elles se heurtent parfois à la réticence des populations
auprès desquelles elles interviennent et qui sont parties au conflit.
Une riposte médicale fondée sur des principes se compose d’interventions cliniques
et opérationnelles inspirées et respectueuses de normes fondamentales, qui mettent
l’accent sur la qualité, la sécurité et la protection dans l’intérêt des patients.

Rabies is a disease of animals but too often the outcome is gauged in terms of human suffering and
death. Despite this, in areas of the world where rabies is endemic there is often a lack of communication between veterinary and medical professionals, to the extent that the disease continues to thri...ve and potential victims are not treated. The problem is partly
exacerbated by a lack of awareness and experience of the disease and of what to do when confronted by suspect cases. In these technologically advanced days, although it is possible to learn “all there is to know” about almost any subject, it is sometimes difficult to distil the essence.

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

Today, patient harm due to unsafe care is a large and growing global public health challenge and is one of the
leading causes of death and disability worldwide. Most of this patient harm is avoidable. As countries strive to
achieve universal health coverage and the Sustainable Development Goals, t...he beneficial effects of improved
access to health services can be undermined by unsafe care. Patient safety incidents can cause death and
disability, and suffering for victims and their families. The financial and economic costs of safety lapses are high.
There is often reduced public confidence and trust in local health systems when such incidents are publicized.
Health workers involved in serious incidents involving death or serious harm to a patient can also suffer lasting
psychological harm and deep-seated feelings of guilt and self-criticism.
