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.

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.

Diabetes mellitus (DM) is a global epidemic with significant morbidity. Diabetic
retinopathy (DR) is the specific microvascular complication of DM and affects 1 in 3 persons with DM. DR remains a leading cause of vision loss in working adult populations. Patients with severe levels of DR are report...ed to have poorer quality of life and reduced levels of physical, emotional, and social well-being, and they utilize more health care resources.
Epidemiological studies and clinical trials have shown that optimal control of blood glucose, blood pressure, and blood lipids can reduce the risk of developing retinopathy and slow its progression. Timely treatment with laser photocoagulation, and increasingly, the appropriate use of intraocular administration of vascular endothelial growth factor (VEGF) inhibitors can prevent visual loss in vision- threatening retinopathy, particularly diabetic macular edema (DME). Since visual loss may not be present in the earlier stages of retinopathy, regular screening of persons with diabetes is essential to enable early intervention.

Glaucoma is a leading cause of irreversible blindness globally. In Malawi, glaucoma accounts for 15.8% of the blindness among people aged 50 years and above. Blindness from glaucoma is preventable with early detection and timely treatment. However, glaucoma management remains a challenge to eye care... providers due to its asymptomatic progression.
These guidelines inform eye care providers about the requirements for early detection of glaucoma, and the appropriate assessment and management of glaucoma patients. The guidelines also demonstrate the need for ophthalmologists to work with secondary-level eye care providers. With
glaucoma being a permanently blinding condition, it is vital to ensure that all eye care providers are adequately equipped with skills and resources for the early detection and management of glaucoma.

During the 17 years since Surgical approaches to the urogenital manifestations of lymphatic filariasis was first published, there has been heightened awareness of the physical, economic and emotional burden of the genitourinary manifestations of filariasis. With the impetus to provide better guidanc...e for care of those suffering from LF, this update was both warranted and timely.
At the outset, the Committee noted that barriers continue to exist in care of patients affected by LF-associated morbidity. These barriers include lack of information for patients as well as for many healthcare providers, including general surgeons and others within health systems
This update offers a new consensus of the Committee regarding the staging of hydroceles caused by LF, also known as “filariceles”. It recommends integrating LF surgery with other efforts to strengthen surgical care by assessing health facilities for their surgical readiness using the WHO surgical assessment tool or “SAT”. It also recommends integratinghernia surgery with hydrocele surgery and integrating standards for prevention of surgical site infection (SSI).
The update revises recommendations for standard procedures and processes, offers an algorithm for diagnosis (including the use of ultrasound) and discusses postoperative care. It recommends collecting data using the staging and grading system described by Capuano and Capuano along with other metrics for public health management of LF.
A multifaceted approach has therefore been recommended to coordinate public health outreach with national surgical planning and local health systems to include supporting partners such as nongovernmental organizations. Surgical camps with mobile teams, as well as training of personnel at DCP3 “first level” or WHO Level II hospitals (depending on region and resources), have important roles for reducing LF morbidity.

Lymphatic filariasis (LF) is an avoidable, debilitating, disfiguring disease caused by infection with the filarial parasites Wuchereria bancrofti, Brugia malayi and B. timori. Globally, 51.4 million people are
estimated to be infected. Lymphoedema and hydrocoele are the visible, chronic clinical co...nsequences of the lymphatic vessel impairment caused by infection with these parasites. Mosquitos in the genera Culex, Anopheles, Mansonia and Aedes transmit the parasites from person to person. 2020 marked the 20th year since WHO established the Global Programme to Eliminate Lymphatic Filariasis (GPELF) which aims to stop transmission of infection with mass drug administration (MDA) and to alleviate suffering among people affected by the disease through morbidity management and disability prevention (MMDP).

The Transformation Agenda (TA) ushered in an ambitious reform process intended to transform the World Health Organization (WHO) into an organization that is proactive, results-driven, accountable and which meets stakeholder expectations, towards transforming and improving public health services in t...he African Region. It aimed to achieve a WHO that is pro-results, which optimally and creatively targets technical work as well as make operations more responsive, with greater effectiveness in both communications and partnerships. The Africa Region has been the epicentre of the human immunodeficiency virus (HIV) epidemic and it’s one of the leading causes of disease and death on the continent. The WHO, with partners, has worked tirelessly for many years to control the threat and reduce the negative impact of the disease. Since the early 2000s, significant progress has been made in the global fight against the scourge of HIV. However, the WCA subregion was falling concerningly behind ESA on several key indicators of progress. In 2016, the WHO joined UNAIDS, UNICEF and other partners in a call for a strong and urgent response to support WCA countries to develop catch-up plans to triple and fast-track ART coverage, to enable the region to catch up with ESA by the end of 2020. Implementation of a widespread test-and-treat strategy, coupled with the scale-up of differentiated service delivery (DSD) and mobilization of requisite funding, accelerated WCA’s progress towards this goal. The HIV treatment catch-up and fast-track plan has achieved its target of seeing the West and Central African region (WCA) catch up with the Eastern and Southern African region’s (ESA) antiretroviral coverage rate of 78% in 2021, albeit later than the 2020 target time frame. A 33% improvement was achieved in WCA, against 21% in ESA, between 2015–2020. WCA achieved a significant 42% increase, compared to ESA’s 23%, between 2015 and 2021, to see WCA draw level with ESA at 78%. In the Democratic Republic of the Congo (DRC) alone, progress of up to 47% was observed between 2015 and 2020, for example. In addition, 1.6 million more People Living with HIV (PLHIV) were enrolled on antiretroviral treatment (ART) between 2015 and 2020.
