Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

First Global Patient Safety Challenge Clean Care is Safer Care
The WHO Guidelines on Hand Hygiene in Health Care provide health-care workers (HCWs), hospital administrators and health authorities with a thorough review of evidence on hand hygiene in health care and specific recommendations to impro...ve practices and reduce transmission of pathogenic microorganisms to patients and HCWs. The present Guidelines are intended to be implemented in any situation in which health care is delivered either to a patient or to a specific group in a population. Therefore, this concept applies to all settings where health care is permanently or occasionally performed, such as home care by birth attendants.

The delivery of humanitarian assistance is expected to slow down significantly over the next seven to ten days in anticipation of the electoral process and limited availability of transport and security assets.
The percentage of extremely food-insecure people who have recei...ved food assistance increased to 65 per cent, as 520,000 people of the targeted 806,000 have now been reached.
Health partners have expressed concern over growing evidence of a spike in cases of severe acute malnutrition in hard-to-reach areas in the Sud region.
Cholera response partners are optimistic that the vaccination campaign of 8 to 15 November will contribute to reducing transmission in Sud and rand’Anse and the risk of a future outbreak

The main objectives of the SOPs are to: (i) establish standards and timelines for response activities; and (ii) guide national governments and GPEI partners in key support functions.
This new version of the SOPs presents overall response requirements for dealing with type 1, 2 and 3 poliovirus fo...llowing monovalent type 2 oral polio vaccine (mOPV2) cessation. Version 2.4 will be valid until release of revised version 3.0 (anticipated May 2018).

The threat posed by Zika virus infection highlights the need to reinforce preparedness arrangements for mosquito-borne diseases in EU/EEA countries, especially for pathogens transmitted by Aedes aegypti and Aedes albopictus.
The aim of this document is to highlight measures that can effectively red...uce the risk of importation and local transmission of pathogens transmitted by Ae. aegypti and Ae. albopictus. The main diseases of concern in this context are Zika, dengue, chikungunya and yellow fever.

WHO today published the new edition of its Model Lists of Essential Medicines and Essential Medicines for Children, which include new treatments for various cancers, insulin analogues and new oral medicines for diabetes, new medicines to assist people who want to stop smoking, and new antimicrobials... to treat serious bacterial and fungal infections.
The listings aim to address global health priorities, identifying the medicines that provide the greatest benefits, and which should be available and affordable for all. However, high prices for both new, patented medicines and older medicines, like insulin, continue to keep some essential medicines out of reach for many patients.

The HIV drug resistance report 2021 summarizes findings from 38 countries that had finalized the surveys by the time of this report and shared data with WHO.
Pretreatment HIVDR to non-nucleoside reverse-transcriptase inhibitors (NNRTI) can affect more than 10% of adults starting therapy and is fo...und up to 3 times more often in people who had previous exposure to antiretroviral drugs. In addition, nearly half of infants newly diagnosed with HIV has HIVDR to NNRTI before initiating treatment.The high levels of observed NNRTI pretreatment HIVDR among emphasize the need to fast-track the transition to WHO-recommended dolutegravir-based ART.

The WHO Global Polio Eradication Initiative (GPEI)’s new Polio Eradication and Endgame Strategic Plan targets the end of all kinds of polioviruses by 2018, including the wild and rare vaccine-related strains which cause paralysis among thousands of children worldwide. The plan is focused on develo...ping and deploying a shot version of the anti-polio vaccine to replace the current oral variant, which is known to occasionally cause the same disease that it is supposed to prevent.

The five hepatitis viruses have different epidemiological profiles, and their impact, duration, and transmission route also vary. The most common transmission routes contributing to the spread of hepatitis are exposure to infected blood via blood transfusion or unsafe injection practices, consumptio...n of contaminated food and drinking water, and transmission from mother to child during pregnancy and delivery. Also, unsafe injection practices, including the use of unsterile needles and syringes, serve as a major pathway for the spread of hepatitis B and C, and reducing transmission of both diseases requires addressing these practices.

23 December 2020 This document summarizes WHO recommendations for the rational use of personal protective equipment (PPE) in health care settings and temporary strategies during acute supply shortages. This document also contains 2 Annex sections describing updated PPE use recommendations for health... workers based on the transmission scenario, setting, and activity in the context of COVID-19 (Annex 1), and updated considerations for the decontamination or reprocessing of PPE (Annex 2). This guidance is intended for public health authorities, organizations, and focal persons involved in decisions regarding PPE distribution, management, and use by health workers.

The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis ...B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.

Injection practices worldwide and especially in low- and middle-income countries (LMICs) include multiple, avoidable unsafe practices that ultimately lead to the large-scale transmission of bloodborne viruses among patients, health care providers and the community at large.
