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.

La enfermedad de Chagas, también llamada tripanosomiasis americana, sigue siendo endémica en 21 países de América Latina. Sin embargo, como consecuencia de las migraciones, la urbanización, la intensificación del turismo, la modificación de las estrategias agrícolas y el cambio climático, l...a enfermedad ha traspasado el marco rural y el ámbito latinoamericano que le dieron identidad durante decenios, y ha logrado instalarse en la periferia de las ciudades del área endémica y en países de América del Norte, Europa, Asia y Oceanía y transformarse en un problema de salud pública global. Teniendo en cuenta que el Chagas afecta a poblaciones en situación de pobreza en las que produce graves consecuencias para la salud y la economía de las personas infectadas, y que los recursos orientados a fomentar el desarrollo de proyectos de investigación, estrategias de control y planes de atención médica a los pacientes detectados son escasos, la Organización Mundial de la Salud (OMS) incorporó esta enfermedad al grupo de enfermedades infecciosas desatendidas (EID) en el año 2005. Se reconoce actualmente la naturaleza multidimensional de la enfermedad de Chagas, cuya caracterización contempla una intrincada trama de aspectos socioculturales, políticos, biológicos, ambientales y sanitarios. Parte sustancial de todo ello radica en el carácter zoonótico de la endemia y la consiguiente imposibilidad de su erradicación. Por ende, resulta muy complicada la construcción de la ruta crítica para enfrentar esta enfermedad, con la aspiración o el objetivo de su eliminación como problema de salud pública. El propósito de esta guía es ofrecer a los Estados Miembros un instrumento que permita actualizar y estandarizar los procesos de evaluación del control, verificación de la interrupción de la transmisión, y validación de la eliminación de la enfermedad de Chagas como problema de salud pública, en consonancia con: a) la Estrategia y plan de acción para la prevención, el control y la atención de la enfermedad de Chagas; b) el Plan de acción para la eliminación de las enfermedades infecciosas desatendidas y las medidas posteriores a la eliminación 2016-2022; c) el Plan de acción sobre entomología y control de vectores 2018-2023; d) guías o procedimientos operativos estandarizados existentes para la verificación o validación de la eliminación de otras enfermedades infecciosas desatendidas (EID) como la oncocercosis, la filariasis linfática y el tracoma, y e) Enfermedades tropicales desatendidas. Prevención, control, eliminación, erradicación.

Leptospirosis is a bacterial zoonotic disease of worldwide importance, though relatively neglected in many African countries including sub Saharan Africa that is among areas with high burden of this disease. The disease is often mistaken for other febrile illnesses such as dengue, malaria, rickettsi...oses and enteric fever. Leptospirosis is an occupational disease likely to affect people working in environments prone to infestation with rodents which are the primary reservoir hosts of this disease. Some of the populations at risk include: sugarcane plantation workers, wetland farmers, fishermen and abattoir workers. In this study we investigated the prevalence of antibodies against Leptospira among sugarcane plantation and factory workers, fishing communities as well as among rodents and shrews in domestic and peridomestic environments within the study areas.

Carlos Chagas discovered American trypanosomiasis, also named Chagas disease (CD) in his honor, just over a century ago. He described the clinical aspects of the disease, characterized by its etiological agent (Trypanosoma cruzi) and identified its insect vector. Initially, CD occurred only in Latin... America and was considered a silent and poorly visible disease. More recently, CD became a neglected worldwide disease with a high morbimortality rate and substantial social impact, emerging as a significant public health threat. In this context, it is crucial to better understand better the epidemiological scenarios of CD and its transmission dynamics, involving people infected and at risk of infection, diversity of the parasite, vector species, and T. cruzi reservoirs. Although efforts have been made by endemic and non-endemic countries to control, treat, and interrupt disease transmission, the cure or complete eradication of CD are still topics of great concern and require global attention. Considering the current scenario of CD, also affecting non-endemic places such as Canada, USA, Europe, Australia, and Japan, in this review we aim to describe the spread of CD cases worldwide since its discovery until it has become a global public health concern.

Chagas is a parasitic disease that affects over 6 million people in the
world. As the disease typically remains asymptomatic for years, new cases
often go unnoticed and unreported, and most people with the disease
are unaware of their condition. Less than 10% of people affected are
diagnosed and... the vast majority do not receive the treatment they need.
If not treated, Chagas may cause irreversible, life-threatening damage to
the heart and other vital organs.

Intestinal schistosomiasis is highly endemic in Tanzania and mass drug administration (MDA) using
praziquantel is the mainstay of the control program. However, the MDA program covers only school aged children
and does not include neither adult individuals nor... other public health measures. The Ijinga schistosomiasis project
examines the impact of an intensified treatment protocol with praziquantel MDA in combination with additional
public health interventions. It aims to investigate the feasibility of eliminating intestinal schistosomiasis in a highly
endemic African setting using an integrated community-based approach.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is a significant public health problem, affecting millions of people worldwide. And although it was described 110 years ago, only two old nitroheterocyclic drugs, benznidazole and nifurtimox, are cu...rrently available for the treatment of Chagas disease and both have several limitations. Besides the clear unmet medical need, many challenges preclude the development of new treatments, some of them related to a lack of understanding of the pathophysiology of the disease and parasite-host interactions. New knowledge and tools are becoming available, but the number of new chemical entities progressing through the preclinical pipeline is inadequate. Therefore, it is still uncertain whether safe, effective and accessible new drugs will be available in the near future. The Chagas disease research community must commit to even greater collaboration to ensure that patients eventually benefit from better treatments.

‘World Rabies Day’ is observed worldwide to mark the death anniversary of Louis Pasteur, a
French biologist, microbiologist and chemist who developed the first rabies vaccine. It’s a day where
Anti Rabies actions are collated, intensified and showcased.
Chagas disease affects 8-10 million people worldwide, mainly in Latin America. The current therapy for Chagas disease is limited to nifurtimox and benznidazole, which are effective in treating only the acute phase of the disease but with severe side effects. Therefore, there is an unmet need for new... drugs and for the exploration of innovative approaches which may lead to the discovery of new effective and safe drugs for its treatment.
