Article Synopsis
- Cameroon has experienced significant urban population growth, with over 67% of urban residents living in slums, and these areas are expanding at a rate of 5.5% annually, prompting concerns about disease transmission and mosquito populations.
- A review of 85 studies from 2002-2021 identified 10 diseases transmitted by mosquitoes, with rising prevalence rates in urban areas for diseases like dengue, while rural areas saw the emergence of previously absent diseases such as Lymphatic filariasis and Rift valley fever.
- Malaria prevalence remained stable in urban settings but decreased in rural areas during the same period, highlighting different disease dynamics in urban versus rural environments.
Article Synopsis
- Understanding the mechanisms behind insecticide resistance in malaria vectors is crucial for effective vector control, specifically focusing on metabolic resistance and genetic variations in North Cameroon.
- The study compared mosquito populations from different regions before and after the distribution of long-lasting insecticidal nets (LLINs), finding increased metabolic resistance in one area, while two others showed decreased effectiveness.
- Genetic analysis showed mixed trends in resistance alleles, indicating evolving resistance patterns, and emphasized the need for alternative vector control methods alongside LLINs in North Cameroon.
Previous studies have indicated widespread insecticide resistance in malaria vector populations from Cameroon. However, the intensity of this resistance and underlying mechanisms are poorly known. Therefore, we conducted three cross-sectional resistance surveys between April 2018 and October 2019, using the revised World Health Organization protocol, which includes resistance incidences and intensity assessments.

- Effective malaria control in North Cameroon was studied after the distribution of long-lasting insecticidal nets (LLINs) in 2010, focusing on Anopheline mosquito behavior and Plasmodium infections from 2011 to 2014.
- Researchers collected 9,376 Anopheline mosquitoes, identifying 14 species, with Anopheles gambiae being the most common, and found that blood meals were mainly from humans and livestock, with indoor Pf-CSP infection rates higher than outdoors.
- The study concluded that even with LLINs, malaria prevalence in children under five was still significant (30%), indicating a need for additional malaria prevention measures.
Dam constructions are considered a great concern for public health. The current study aimed to investigate malaria transmission in the Nyabessan village around the Memve'ele dam in South Cameroon. Adult mosquitoes were captured by human landing catches in Nyabessan before and during dam construction in 2000-2006 and 2014-2016 respectively, as well as in the Olama village, which was selected as a control.
