In Cameroon, mosquitoes transmit various arboviruses, posing significant health risks. We aimed to characterize the virome in southwestern Cameroon and identify potential core viruses which might be associated with vector competence. A total of 398 mosquitoes were collected from four locations (Bafoussam, Buea, Edea, and Yaounde).

Dengue fever is a mosquito-borne viral infection that continues to pose a significant public health threat globally, including Nigeria. Here, we provided a review of dengue fever outbreaks in Nigeria from 1972 to 2023, examining the epidemiology, prevention strategies, challenges faced in combating the disease, and recommendations to mitigate its spread and transmission. We utilized scholarly databases such as PubMed and Google Scholar in writing this paper.

Article Synopsis
- Ilhéus virus (ILHV) is an arbovirus found in Central and South America and the Caribbean, first identified in 1944, with limited studies on its pathogenesis and vector competence.
- Researchers developed a murine model to study ILHV, demonstrating that it can cause severe neurological disease in mice, particularly in immunocompromised and age-specific groups.
- The virus was shown to replicate efficiently in various vertebrate and invertebrate cell lines, and studies suggest that certain mosquito species can effectively transmit ILHV, indicating a risk of the virus emerging in new regions.

Aedes mosquitoes are the main vectors of arboviruses in Benin. Cases of dengue have been reported in Benin with all four serotypes of the virus actively circulating in this region. Some agricultural settings are known to harbor Aedes vectors responsible for the transmission of arboviruses.

This study aims to determine the frequency and clinical manifestations of dengue and chikungunya viral infections in the district hospital of Mfou, Centre region of Cameroon where malaria is endemic. Blood samples were collected from suspected cases and tested for Plasmodium parasites and for the molecular detection of viral RNAs (dengue, zika and chikungunya viruses) using TRIOPLEX qPCR. A total of 108 patients were clinically suspected among which 25 % were male and 50 % were less than 15.
