Trypanosomosis and Transhumance: Contributions to Contemporary Conflicts Between Farmers and Herdsmen Along the Tsetse Fly Belts: Mathematical Modeling and Systematic Field Analysis Approach.
Acta Biotheor

Department of Veterinary Parasitology and Entomology, Faculty of Veterinary Medicine, University of Ibadan, Ibadan, Nigeria.
Conflicts within the tsetse fly belt revealed a strong correlation between the dynamics of bovine trypanosomosis and the insurgency involving farmers and herders in Nigeria and parts of West Africa. This study examined the history, causes and influence of farmers-herdsmen conflicts on banditry, terrorism and food security as it relates to the epidemiology of African animal trypanosomosis (AAT). A combination of literature database searches, semi-structured questionnaires, and mathematical modeling was employed.

Rapid urbanization and migration in Latin America have intensified exposure to insect-borne diseases. Malaria, Chagas disease, yellow fever, and leishmaniasis have historically afflicted the region, while dengue, chikungunya, and Zika have been described and expanded more recently. The increased presence of synanthropic vector species and spread into previously unaffected areas due to urbanization and climate warming have intensified pathogen transmission risks.

Background And Objectives: Non-viral bloodborne diseases are a group of infections that are a public health problem worldwide. The incidence of diseases such as brucellosis and syphilis is increasing in the Americas and Europe. Chagas disease is an endemic problem in Latin America, the United States and Europe.

Article Synopsis
- Non-human primates (NHPs) in Brazil were studied to investigate the infection rates of Trypanosoma minasense, with a focus on how landscape composition and forest fragmentation affected these rates.
- Sapajus nigritus showed the highest positivity for T. minasense in blood samples (60.9%), while other species like Callithrix spp. and Alouatta guariba clamitans had lower rates, but molecular analysis indicated significant infections in all groups.
- The study found a correlation between T. minasense infections and environmental factors: higher forest fragmentation led to increased infection rates in NHPs, suggesting that habitat loss may drive disease prevalence.
Barriers and facilitators for preventing mother-to-child transmission of Trypanosoma cruzi and hepatitis B in the Gran Chaco region: a qualitative analysis using the consolidated framework for implementation research (CFIR).

Background: Mother-to-child transmission (MTCT) of Trypanosoma cruzi and hepatitis B virus (HBV) increases morbidity and disability in Latin America and the Caribbean. The tailormade comprehensive antenatal care based on the Framework for the elimination of MTCT of HIV, syphilis, hepatitis B virus (HBV), and Chagas disease (EMTCT Plus) has been implemented in the region since 2018 through a private-public partnership. This study aimed to estimate the effectiveness of the intervention in preparing MTCT of T.
