A comprehensive, advanced educational resource and disseminator of basic and clinical information dealing with all aspects of the global problems associated with the acquisition of parasitic diseases that adversely affect people around the world.
As infectious diseases such as SARS, Monkeypox, Polio, HIV, and Ebola travel the globe and garner media attention, Parasites Without Borders staff are curating resources in a timely, ongoing basis.
A comprehensive, advanced educational resource and disseminator of basic and clinical information dealing with all aspects of the global problems associated with the acquisition of parasitic diseases that adversely affect people around the world.
What can I do to help eliminate human suffering due to parasitic infections? One answer is to lead to ones strengths. For us the choice was easy; more and better education for all those in a position to apply medical knowledge directly to populations most in need of solutions to alleviate the burden of parasitic diseases.
Help bring the latest medical and basic biological information pertaining to diseases caused by eukaryotic parasites to every practicing physician and medical student within the United States.

Throughout February, March and April, donations made to Parasites Without Borders (PWB) will be matched by the organization and donated to the American Society of Tropical Medicine and Hygiene (ASTMH)
Throughout February, March and April, donations made to Parasites Without Borders (PWB) will be matched by the organization and donated to the American Society of Tropical Medicine and Hygiene (ASTMH) with a minimum pledged donation of $15,000 and a total gift of up to $30,000 for ASTMH. A portion of these funds will go to providing Travel Awards for three qualified female students, early-career investigators or scientists actively working in the tropical medicine field from low- and middle-income countries to attend the ASTMH 2023 Annual Meeting.
Founded in 1903, ASTMH is the largest international scientific organization of experts dedicated to reducing the worldwide burden of tropical infectious diseases and improving global health. ASTMH accomplishes this through generating and sharing scientific evidence, informing health policies and practices, fostering career development, recognizing excellence and advocating for investment in tropical medicine/global health research.

The Problem
Common Parasitic Infections
The world is getting smaller. Global shrinkage is real and is driven by information overload from the internet, CNN, The BBC, NPR, and Al jazeera, to name a few. All the while, the human population continues to grow, exacerbating unresolved issues of rapid urbanization that is being caused by the predictable adverse effects of rapid climate change on the environment. Yet, for some of us, especially if we are among the few millions of lucky ones, our lives will continue essentially unchanged, enriched by complex, interesting cultures. We will work hard for our income, and most importantly we will not worry about where our next meal comes from. Becoming physically and psychologically compromised by some exotic disease entity – malaria or schistosomiasis – seems as remote a possibility as waking up surrounded by a host of other life-threatening issues.
Malaria
There were an estimated 198 million cases of malaria worldwide (range 124-283 million) in 2013, and an estimated 584,000 deaths (range 367,000 - 755,000).
African
Trypanosomiasis
In 1995, WHO Expert Committee estimated that 60 million people were at risk with an estimated 300,000 new cases per year in Africa, with fewer than 30,000 cases diagnosed and treated.
American
Trypanosomiasis
About 6 million to 7 million people worldwide, mostly in Latin America, are estimated to be infected with Trypansosoma cruzi, the parasite that causes Chagas disease.
Leishmaniasis
The leishmaniases are a group of diseases caused by protozoan parasites from more than 20 Leishmania species. These parasites are transmitted to humans by the bites of the infected female phlebotomine sandfly.
Schistosomiasis
Estimates show that at least 258 million people required preventive treatment for schistosomiasis in 2014. More than 61.6 million people were reported to have been treated for schistosomiasis in 2014.
Ascariasis
Ascaris infection due to A. lumbricoides occurs worldwide; approximately 800 million people are infected.
Hookworm
Hookworm is an intestinal parasite most commonly found in tropical and subtropical climates worldwide, particularly in Africa, South East Asia, the Western Pacific, Latin America and the Mediterranean.
Trichuriasis
An estimated 604-795 million people in the world are infected with whipworm. Whipworm, hookworm, and Ascaris are known as soil-transmitted parasitic worms.
Our Team
For the purpose of eliminating human suffering due to parasitic infections it is essential that there is more and better education for all those in a position to apply medical knowledge directly to populations most in need of solutions to alleviate the burden of parasitic diseases. The three of us have had a life-time of experience in teaching parasitic diseases to students of medicine, both within the U.S.A. and abroad.
