In this study, we developed a Caputo-Fractional Chlamydia pandemic model to describe the disease's spread. We demonstrated the model's positivity and boundedness, ensuring biological relevance. The existence and uniqueness of the model's solution were established, and we investigated the stability of the α-fractional order model.

Brucellosis, a prevalent zoonotic disease caused by bacteria from the genus , presents a substantial public health and economic challenges worldwide. In this paper, we formulate a two-patch deterministic model to investigate the impact of short-term displacement of domestic animals on the transmission dynamics of brucellosis within and between patches with heterogeneous risk of infection. The model analysis is performed, and the basic reproduction number is computed and used in the stability analysis of equilibria.

Climate change is an urgent global health challenge, with floods becoming increasingly frequent and exacerbating the spread of infectious diseases. With its diverse climates and recurring natural disasters, Latin America is particularly susceptible to outbreaks following floods. These events disrupt ecosystems and create ideal conditions for the spread of waterborne and vector-borne pathogens.

Human cases of arboviral disease transmitted by mosquitoes are increasing worldwide and spreading to new areas of the United States. These diseases continue to re-emerge, likely due to changes in vector ecology, urbanization, human migration, and larger range of climatic suitability. Recent shifts in landscape and weather variables are predicted to impact the habitat patterns of urban mosquitoes such as and .

Introduction: The COVID-19 pandemic has deeply affected Latin American countries, with countless COVID-19 cases and deaths. In countries like Mexico, Brazil, Peru, Colombia and Ecuador, the public health system collapsed and the lack of testing capacity did not allow control of the spread of SARS-CoV-2 during the first year of the COVID-19 pandemic. Moreover, rural and Indigenous communities in these countries, particularly isolated ones like those in the Amazon Basin, were neglected in terms of access to COVID-19 testing and medical aid.
