The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and ...its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels.

La fourniture de sang et de produits sanguins sûrs et efficaces pour la transfusion ou la fabrication d’autres produits sanguins fait intervenir un certain nombre de processus, allant de la sélection des donneurs de sang et de la collecte, au traitement et au dépistage des dons de sang ainsi qu...’à l’analyse des échantillons des malades, à la délivrance de sang compatible et à son administration au patient. Il existe un risque d’erreur à chaque étape de la « chaîne de transfusion », et une défaillance à une quelconque de ces étapes peut avoir des conséquences graves pour les receveurs du sang ou des produits sanguins. Si la transfusion sanguine peut sauver des vies, elle comporte aussi des risques, en particulier la transmission des infections par le sang.
Le dépistage des infections transmissibles par transfusion (ITT) en vue d’exclure les dons de sang présentant un risque de transmettre une infection du donneur aux receveurs est une étape critique du processus visant à garantir au mieux la sécurité des transfusions. Un dépistage efficace des agents transmissibles par le sang les plus courants et les plus dangereux peut réduire le risque de transmission à des niveaux très faibles.

The role of malacological surveys to identify potential transmission sites for schistosomiasis control in this era of
mass drug administration have received little attention. In that context, the present study was conducted to
...
determine the abundance, identity and disease transmission potential of intermediate host snails for intestinal
schistosomiasis on Ijinga Island, north-western Tanzania.

In 2009, WHO’s Second International Conference on Buruli Ulcer Control and Research resolved to strengthen the capacity of national laboratories to confirm cases of the disease, but advised that “efforts are still needed to develop simple diagnostic tools usable in the field as well as disabilit...y prevention methods”.
In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer

Female Genital Schistosomiasis (FGS) is a gynaecological disease caused by Schistosoma haematobium, a parasitic worm that is acquired by skin contact with freshwater contaminated by schistosome cerceriae. Communities in which the infection is most endemic have limited access to clean water and healt...hcare services. Up to 150 million adolescent girls and women are estimated to be at risk of FGS and about 16–56 milion womens are living with FGS, with the majority of these in sub-Saharan Africa. The variability of these estimates points to the fact that this neglected tropical disease is not well studied and frequently not prioritized by local, regional, and global health policy makers.

Infectious diseases like COVID-19 can disrupt the environments in which children grow and develop. Disruptions to families, friendships, daily routines and the wider community can have negative consequences for children’s well-being, development and protection. In addition, measures used to preven...t and control the spread of COVID-19 can expose children to protection risks. Home-based, facility-based and zonal-based quarantine and isolation measures can all negatively impact children and their families.
The aim of this brief is to support child protection practitioners to better respond to the child protection risks during a COVID-19 pandemic. Part 1 presents the potential child protection risks COVID-19 can pose to children. Part 2 presents programmatic options in line with the 2019 Minimum Standards for Child Protection in Humanitarian Action (CPMS) and the Guidance Note: Protection of Children During Infectious Disease Outbreaks.

22 July 2022. This document summarizes current WHO guidance for public health surveillance of coronavirus disease 2019 (COVID-19) in humans caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
The aim of this document is to provide interim guidance for interventions to reduce the risk of maternal Zika virus infection and to manage potential complications during pregnancy. This guidance is based on the best available research evidence and covers areas prioritized by an international, multi...disciplinary group of health care professionals and other stakeholders. Specifically, it presents guidance for preventing Zika virus infection;antenatal care and management of women with infection; and care during pregnancy for all pregnant women living in affected areas, with the aim of optimizing health outcomes for mothers and newborns.

Second editon. This document serves only as a guide to good practice and may help to harmonize surveillance activities. The purpose of this manual is to be a handy reference for key elements and contact information for all communicable diseases / syndromes associated with current WHO control program...mes. It should be particularly useful at the Ministry of Health level in Member States, in approaching integrated surveillance of communicable diseases / syndromes.
The document is intended to be updated on a regular basis. This reflects the changing nature of infectious diseases and accompanying diagnostic and surveillance methods. It also reflects the multidisciplinary nature of disease surveillance in which many different programmes and partners are involved.

The socioeconomic factors and public health inadequacies that facilitated the rapid spread of this infection continue to exist. As it is a new and emerging disease it has not received sufficient coverage yet in the medical curricula of Member States. Specific treatment is not available, and there is... no vaccine for the prevention of chikungunya fever. It has therefore become imperative to develop guidelines, based on the limited clinical experience gathered from managing patients so far, for appropriate management of patients in communities and in health facilities. Experts engaged in managing patients with chikungunya fever in the Region were brought together by the WHO Regional Office for South-East Asia to outline guidelines for managing various situations and stages of the disease.
