Study of Mansonellosis and Oropouche Fever: Vectors, Life Cycle, Transmission, Pathogenesis, and Diagnosis

Culicoides bites cause discomfort to humans due to an allergic reaction resulting from the proteins in their salivary glands, but they also cause great pain, especially when present in large numbers. They can cause reactions such as allergic dermatitis, papules, and pustules, and even more serious reactions such as eczema, scaling, and scarring with abnormal pigmentation of the human skin, in addition to being vectors of diseases. The objective of this manuscript is to describe mansonellosis and Oropouche fever, as well as their vector, life cycle, transmission, pathogenesis, and diagnosis. Data were collected using a quantitative and descriptive approach, through books and the following databases: SciVerse Scopus, Scientific Electronic Library Online (SciELO), and the Academic Search Tool (Scholar Google). The search was developed using the subject descriptor mosquito, diseases, hosts, transmission, diagnosis, and treatment mentioned in journals, through a review of the literature on the subject. In the initial search, the titles and abstracts of the articles were considered for the broad selection of works of probable interest, with the abstracts being highlighted. The time frame used was between 1972 and 2024, with a preference for searches of recent publications, and those that did not meet the established criteria were excluded.
