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.

This Training module on malaria elimination has been developed by WHO to support health professionals in planning, managing, monitoring and evaluating malaria elimination programmes
As of 31 October 2020 This is the tenth edition of this summary of rapid systematic reviews, which includes the results of a rapid systematic review of currently available literature. More than 200 therapeutic options or their combinations are being investigated in more than 1,700 clinical trials. I...n this review, 46 therapeutic options are examined. The Pan American Health Organization (PAHO) is continually monitoring ongoing research on any possible therapeutic options. As evidence emerges, then PAHO will immediately assess and update its position, and particularly as it applies to any special sub-group populations such as children, expectant mothers, those with immune conditions, etc.

The biennium 2020–2021 has revealed more clearly than ever the need for a strong, credible and independent WHO on the world stage. The coronavirus disease (COVID-19) crisis has demonstrated the fundamental importance of the global detection, response and coordination roles that only WHO can play a...cross all Member States. At the same time, the challenges to global health systems and the pressure to ensure equal access to quality health care and the best health possible for all have mounted. The triple billion targets of the Thirteenth General Programme of Work, 2019–2023 remain relevant. The work of WHO in all contexts has never been more critical. However, as several Member States have pointed out, the COVID-19 pandemic has highlighted the discrepancy between what the world expects of WHO and what it is able to deliver with the resources/capacity it has at its disposal. Sustainable financing is thus a key challenge for the Organization that must be addressed as part of the lessons learned from the current COVID-19 pandemic. Member States discussed this issue in detail during the Seventy-third World Health Assembly and their conclusions were reflected in resolution WHA73.1 (2020). The topic of adequate funding is not new. However, discussions on the matter have, to date, remained rather abstract. Building on previous discussions and taking account of lessons learned, the WHO Secretariat would like to initiate a process aimed at finding a concrete solution to the sustainable financing of WHO. This document proposes a process through which to arrive at such a decision, including the key stages and timeline.

Guidance for health workers
Schistosomiasis is a public health problem in tropical and subtropical regions of Africa, Asia, the Caribbean and South America. It is one of the neglected tropical diseases (NTDs) - a group of diseases and conditions that affect particularly low-income populations, worldwide.
Last year, WHO laun...ched a new road map for 2021-2030 that aims to end the suffering from NTDs by 2030, in line with the Sustainable Development Goals. The road map specifically targets the elimination of schistosomiasis as a public health problem, globally.
This guideline provides evidence-based recommendations in the following areas: prevalence thresholds, target age groups and frequency of PC, establishment of WASH and snail control activities to support control and elimination of schistosomiasis, diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs, in snail hosts, and in humans.
