Special Issue Information

Dear Colleagues,

This Special Issue focuses on current efforts to develop vaccines against Neglected Tropical Diseases.  The World Health Organization estimates that over 1 billion people globally are affected by Neglected Tropical Diseases (NTDs). The core group of 13 major neglected tropical diseases includes parasitic worm infections (roundworm, hookworm, and whipworm infection), lymphatic filariasis (elephantiasis), schistosomiasis (snail fever), onchocerchiasis (river blindness), dracunculiasis (guinea worm infection); protozoal infections including Chagas disease, leishmaniasis, and African trypanosomiasis (sleeping sickness); and bacterial infections including trachoma, Buruli ulcer, and leprosy. A commonality of these NTDs is that they are chronic conditions resulting in poor growth, disfigurement, and poor general health with low mortality rates. These NTDs are highly prevalent in impoverished areas of Asia, India, Subsaharan Africa, and Central and South America with several diseases occurring concurrently in the same geographical location. Since the initiation of the Millennium Development goals, significant progress has been made toward eliminating or reducing several of these diseases, including dracunculiasis, lymphatic filariasis,  and roundworm infection through community education programs, vector control programs, and improving detection and treatment, including Mass Drug Administration (MDA) campaigns. Despite these gains, little progress has been made toward controlling or eliminating other NTDs, including trichuriasis, hookworm, and Chagas disease. To move towards better control of these diseases, there is an urgent need for low cost effective treatments to complement community education, vector control and improved sanitation practices. Vaccines are an attractive, low cost option for widespread sustained control. Global research efforts have advanced the understanding of immune control of these diseases and identified several new promising candidates that may soon be available to complement current treatment strategies, effecting significant gains in global health.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Tropical Medicine and Infectious Disease is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

Nipah virus (NiV) is a zoonotic paramyxovirus of the Henipavirus genus first identified in Malaysia in 1998. Henipaviruses have bat reservoir hosts and have been isolated from fruit bats found across Oceania, Asia, and Africa. Bat-to-human transmission is thought to be the primary mode of human NiV infection, although multiple intermediate hosts are described. Human infections with NiV were originally described as a syndrome of fever and rapid neurological decline following contact with swine. More recent outbreaks describe a syndrome with prominent respiratory symptoms and human-to-human transmission. Nearly annual outbreaks have been described since 1998 with case fatality rates reaching greater than 90%. The ubiquitous nature of the reservoir host, increasing deforestation, multiple mode of transmission, high case fatality rate, and lack of effective therapy or vaccines make NiV’s pandemic potential increasingly significant. Here we review the epidemiology and microbiology of NiV as well as the therapeutic agents and vaccines in development. Full article

Chagas disease is a major neglected tropical disease, transmitted predominantly by triatomine insect vectors, but also through congenital and oral routes. While endemic in the Americas, it has turned into a global disease. Because of the current drug treatment limitations, a vaccine would represent a major advancement for better control of the disease. Here, we review some of the rationale, advances, and challenges for the ongoing development of a vaccine against Chagas disease. Recent pre-clinical studies in murine models have further expanded (i) the range of vaccine platforms and formulations tested; (ii) our understanding of the immune correlates for protection; and (iii) the extent of vaccine effects on cardiac function, beyond survival and parasite burden. We further discuss outstanding issues and opportunities to move Chagas disease development forward in the near future. Full article
