Trachoma is the leading infectious cause of blindness (2). It is characterized by repeated
conjunctival infection with particular strains of Chlamydia trachomatis. This scars the conjunctivae and,
in some cases, leads to trichiasis with or without entropion. The abrasive action of eyelashes can

This new guidance aims to support programme implementers, coordinators and others in humanitarian settings in their actions to counter suicide and self-harm in humanitarian contexts and to save lives.
International commitment to eliminate trachoma as a public health problem worldwide is supported by resolution WHA51.11 of the World Health Assembly .1 Important progress towards this goal has been made by harnessing the mostly informal relationships that exist between partners including Member Stat

es, the World Health Organization (WHO), academic institutions, donors and nongovernmental organizations. Recognizing that work remains to be done and that the 2020 target2 for elimination is rapidly approaching, in February 2015 the WHO Department of Control of Neglected Tropical Diseases convened a group of academic institutions that had for many years helped WHO to implement its mandate on trachoma and to work towards establishing a Network of WHO collaborating centres (WHOCCs) for Trachoma. The report of that meeting has been published.

lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

ts to the meeting. He said the World Health Organization’s Department of Control of Neglected Tropical Diseases (WHO/NTD) was in a state of transition. Following the death of the late esteemed Director Dr Mwelecele Ntuli Malecela earlier in the year, Dr Gautam Biswas had taken over as Acting Director but would soon retire; the appointment of a new Director was under way. Owing to rotation of STAG-NTD members, this would be the last meeting for some and the first meeting for several new participants. The work however would continue with the same commitment. Discussions over the next two days would focus on critical issues regarding recovery of NTD services following the disruptions caused by coronavirus disease (COVID-19), which had impacted many health services worldwide. He looked forward to receiving the advice and guidance of STAG-N

Therefore, the main objective of this manual is to provide practical tools, techniques and procedures to strengthen sand fly control and surveillance in order to improve implementation of leishmaniasis control programmes. The manual provides a rationale for programme managers in different geographical regions on the types of vector control interventions to be used in different epidemiological and environmental settings and also how to measure their impact.

Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga

s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

This fourth annual report monitors global progress towards the 2023 target for global elimination of industrially produced trans-fatty acids (TFA), highlighting achievements during the past year (October 2021 – September 2022). Countries are responding to the World Health Organization (WHO) call t

Over the past year, several additional countries took action to eliminate industrially produced TFA: best-practice policies came into effect in India in January 2022, Uruguay in May 2022 and Oman in July 2022. Best-practice policies were passed in Bangladesh in November 2021 (to come into effect in December 2022) and in Ukraine in September 2020 (to come into effect in October 2023), best-practice TFA policies are projected to pass soon in Mexico, Nigeria and Sri Lanka.

Discrete typing units of Trypanosoma cruzi: Geographical and biological distribution in the Americas
Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m

anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.
