![]() In addition, the NIAID has set priorities for drug development for treatment of category B pathogens. Given the toxicity that can be associated with this class and potential concerns for development of resistance, as has already been reported for some anaerobic pathogens, new therapies are needed. Nitroimidazoles are the mainstay treatment for invasive amebiasis. There is no vaccine to prevent amebiasis. Earlier descriptions of amebiasis relying solely on microscopy may have been obscured by these nonpathogenic strains. bangladeshi are considered nonpathogenic. moshkovskii may cause diarrhea, whereas E. Of the many Entamoeba species that infect humans, 3 species are morphologically indistinguishable from E. histolytica from nonpathogenic species of Entamoeba. Īdvances in molecular diagnostic methodologies have improved our understanding and led to the recognition and separation of E. histolytica is one of the most common causes of infectious diarrhea among travelers returning from endemic areas. Even in low-incidence settings, these properties of the parasite lead to outbreaks among military and general populations. ![]() histolytica is classified as a category B priority biodefense pathogen by the National Institute of Allergy and Infectious Diseases (NIAID) because of its low infectious dose, chlorine resistance, and environmental stability, properties that can pose a threat of easy dissemination through contamination of food and water supplies. Fulminant amebic colitis is an uncommon complication of amebiasis but is associated with high mortality, and on average more than 50% with severe colitis die. Amebic colitis is a leading cause of severe diarrhea worldwide and is listed among the top 15 causes of diarrhea in the first 2 years of life in children living in the developing world, where diarrhea remains the third leading cause of death, accounting for 9% of all deaths in children under the age of 5 years. The significance of amebiasis is exemplified in several ways. Amebiasis can be asymptomatic or can lead to the development of severe infection with amebic colitis and amebic liver abscess. The median benefit–cost exceeds one for five of the six priority conditions in middle-income countries, and exceeds one for four of the six priority conditions in low-income countries, with a range of 1♴:1 to 24:1.Amebiasis is caused by infection with the pseudopod-forming, nonflagellated protozoan parasite Entamoeba histolytica. The economic case for such investment is strong. As an example of the potential impact, 1♱ million premature deaths in low-income and middle-income countries could be avoided annually by reducing the diagnostic gap for six priority conditions: diabetes, hypertension, HIV, and tuberculosis in the overall population, and hepatitis B virus infection and syphilis for pregnant women.ħ. Innovations within the past 15 years in many areas (eg, in financing, technology, and workforce) can reduce the diagnostic gap, improve access, and democratise diagnostics to empower patients.Ħ. The COVID-19 pandemic has emphasised the crucial role of diagnostics in health care and that without access to diagnostics, delivery of universal health coverage, antimicrobial resistance mitigation, and pandemic preparedness cannot be achieved.ĥ. The level of primary health care is the diagnostic so-called last mile and particularly affects poor, rural, and marginalised communities globally appropriate access is essential for equity and social justice.Ĥ. This notion is under-recognised, leading to underfunding and inadequate resources at all levels.ģ. Diagnostics are central and fundamental to quality health care. 47% of the global population has little to no access to diagnostics.Ģ. The Executive Summary and Key Recommendations are also available in Spanish and French.ġ. The Commission puts forward recommendations to accelerate and transform access to diagnostics globally. Diagnostics are central to an accurate diagnosis of communicable and non-communicable diseases, to guide therapy, monitor progress, and assess response to treatment. There is an urgent need to strengthen diagnostics for future pandemic preparedness but also beyond pandemics. The COVID-19 pandemic has shown acutely that diagnostic capacity in a country is directly linked to the ability to respond to the pandemic with appropriate public health measures and to monitor emerging variants. Yet, almost half of the global population has little or no access to diagnostics.
