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.

Antimicrobial resistance represents a big threat to public health. The Centers for Disease Control and Prevention (CDC) estimate that every year two million Americans are infected with a (multi-)drug resistant bacterium, resulting in 23,000 deaths. The WHO has repeatedly drawn attention to this majo...r health issue. In the worst-case scenario, we will shortly run out of effective antibiotics. Surgery and cancer therapy will then become very dangerous due to the risk of infection associated with such treatments. (Organ) transplantation will become close to impossible as the immunosuppression necessary for transplant patients makes them highly vulnerable to infections. Some infections we can easily treat today could turn deadly. It is therefore conceivable that infectious diseases once again become the leading cause of death as in early 20th century.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

Historically, the discovery of the sulfa drugs in the 1930s and the subsequent development of penicillin during World War II ushered in a new era in the treatment of infectious diseases. Infections that were common causes of death and disease in the pre-...antibiotic era - rheumatic fever, syphilis, cellulitis and bacterial pneumonia - became treatable, and over the next 20 years most of the classes of antibiotics that find clinical use today were discovered and changed medicine in a profound way. The availability of antibiotics enabled revolutionary medical interventions such as cancer chemotherapy, organ transplants and essentially all major invasive surgeries from joint replacements to coronary bypass. Antibiotics, though, are unique among drugs in that their use precipitates their obsolescence. Paradoxically, these cures select for organisms that can evade them, fueling an arms race between microbes, clinicians and drug discoverers.

ECDC Technical Report
In line with ECDC’s recommendations provided in the ’Risk Assessment of HTLV-1/2 transmission by tissue/cell transplantation’ dated 14 March 2012, this Directive replaces the term ‘incidence’ with ‘prevalence... in the description of endemic areas of HTLV-1/2 infection. According to the new requirements ‘HTLV-1 antibody testing must be performed for donors living in, or originating from high-prevalence areas or with sexual partners originating from those areas or where the donor’s parents originate from those areas’ and this applies to both donors of non-reproductive tissues and cells and reproductive cells.
ECDC contracted experts from the Institut Pasteur in Paris to systematically review the published evidence on the distribution of HTLV-1 infection prevalence throughout the world and to identify high-prevalence countries and areas.

The report reveals that good IPC programmes can reduce health care infections by 70 %. oday, out of every 100 patients in acute-care hospitals, seven patients in high-income countries and 15 patients in low- and middle-income countries will acquire at least one health care-associated infection (HAI)... during their hospital stay. On average, 1 in every 10 affected patients will die from their HAI.
People in intensive care and newborns are particularly at risk. And the report reveals that approximately one in four hospital-treated sepsis cases and almost half of all cases of sepsis with organ dysfunction treated in adult intensive-care units are health care-associated.

Maternal mortality has fallen significantly in recent years, especially in countries that have emphasized the prevention of its main causes, such as hemorrhagic and infectious complications and hypertension , including in the Region of the Americas. In its final report on the Plan of Action to Accel...erate the Reduction of Maternal Mortality and Severe Maternal Morbidity, the Pan American Health Organization (PAHO) reported a continuing downward trend in maternal mortality, with an 18.1% reduction in the maternal morbidity ratio during the period 2010-2015 . From a pathophysiological perspective, death events are a common end result of a wide spectrum of complications leading to multi-organ dysfunction. However, there is a group of women in this situation who survive, despite the seriousness of their condition. This high number of patients––who were in serious condition
but did not die––reflects the actual health conditions in an institution or a country. For this reason, there is a need to create indicators to estimate morbidity in women due to diseases and incidents that occur during pregnancy, childbirth, and the puerperium. To this end, we propose conducting epidemiological surveillance of an indicator that includes women who survived after presenting a potentially fatal complication during pregnancy, childbirth, or the puerperium, reflecting quality medical attention and care (5, 6). This indicator
is maternal near-miss (MNM), which refers to extremely severe maternal morbidity––cases of a severity that
brings women very close to the death event. After adjusting the definition to a specific population and time,
MNM is defined as a case in which a woman nearly died, but survived a complication that occurred during
pregnancy, childbirth, or within 42 days of termination of pregnancy

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 guidance document has been produced by WHO to assist blood services in the development of national plans to respond to any emerging infectious threats to the sufficiency or safety of the blood supply, whether from an existing infectious agent that is changing in incidence and spread, or from a ...newly identified infectious agent. It is intended that this document be followed to guide the national blood service through the process of planning how to respond in a timely, controlled and appropriate way to any specific infectious threat that may subsequently emerge. It is acknowledged that it is not only the blood supply that may be affected by such emerging infectious threats; in those countries undertaking transplantation, the supply of cell, tissues and organs may also be threatened. Increasingly, blood services are taking overall national responsibility for transplantation in their capacity as the organization responsible for the collection, processing, storage and supply of cells, tissues and organs. This approach is both sensible and appropriate, as the overall donor selection and screening processes are the same or very similar. This guidance document can therefore also be used to assist those bodies responsible for the provision of cells, tissues and organs to prepare for an emerging infectious threat.

Successful detonation of an improvised nuclear device (IND) would be a catastrophic event, causing an unprecedented number of injuries and lives lost, as well as economic, political, and social disruption. However, an effective medical response and an infrastructure prepared to protect itself from f...allout could save tens of thousands of lives. Since 2001, all levels of government, academic institutions, and professional organizations have done significant work to enhance our ability to prepare for and respond to a nuclear detonation. The following manual is intended to simplify and translate the necessary protective actions and medical response modalities in order to make them more accessible and easier to translate into practice. The approach of this manual is to provide a common baseline application for various allied response disciplines (to include senior operational responders, emergency managers, public health advisors, and municipal, State, and Federal executives and elected officials). This manual will enhance mutual understanding of the basics of nuclear response.
