Since its discovery in Nigeria 1991, Aedes albopictus has invaded much of Central Africa, a region where Ae. aegypti also occurs. To assess the relationship between invasion by and recent emergence dengue virus (DENV) chikungunya (CHIKV), we undertook vector competence experiments on populations collected from Cameroon conducted field investigations during concurrent epidemics DENV CHIKV Gabon. Overall, infection dissemination rates were not significantly different when exposed to titers...
Although arboviral infections including Chikungunya virus (CHIKV) are common in sub-Saharan Africa, data on their circulation and prevalence poorly documented. In 2006, more than 400 cases of dengue-like fever were reported Kumbo (Northwest Region Cameroon). The aim this study was to identify the aetiology define its extent area. We conducted a cross-sectional seroprevalence survey one year after clinical investigations infection. An entomological consisted collection identification mosquito...
Background Dengue is not well documented in Africa. In Cameroon, data are scarce, but dengue infection has been confirmed humans. We conducted a study to document risk factors associated with anti-dengue virus Immunoglobulin G seropositivity humans three major towns Cameroon. Methodology/Principal Findings A cross sectional survey was Douala, Garoua and Yaounde, using random cluster sampling design. Participants underwent standardized interview were blood sampled. Environmental housing...
Abstract Background Cold chain monitoring is a precondition to ensure immunization quality, efficacy and safety. In Cameroon, the Expanded Program on Immunization (EPI) has National Standard Operating Procedure (SOP) that describes vaccines, cold system equipment, its use recommended procedures control monitor temperatures chain. This study was conducted assess status of in eight health districts Cameroon. Findings The carried out fifty with poor coverage rate. Data were collected using...
Arboviruses are a major public health problem worldwide and predominantly present in intertropical areas. Chikungunya, dengue zika viruses have been implicated recent epidemics Asia, America Africa. In Cameroon, data on these fragmentary. The purpose of this study was to determine the frequency detection three febrile patients Douala, Cameroon. A cross-sectional descriptive conducted from March April 2017 at New-Bell District Hospital Douala. Blood samples were collected tested for malaria...
Insecticide treated materials remain the mainstay for malaria prevention. The current study reports on entomological impact of cyfluthrin impregnated bed nets transmission in Mbandjock, a semi urban locality southern Cameroon. Several findings pertaining to recent distribution LLINs across Cameroon are discussed. Malaria and vector bionomics were monitored before after net coverage. Bed distributed whereas Nkoteng was free during entire period. January June 1997 represented period coverage...
To date, only a few cases of malaria and dengue co-infections have been reported around the world. We describe for first time in Cameroon, concurrent infections among children (2 to 10 years) two health centers Yaoundé. The strains isolated Cameroon clustered with Asian II genotype. Although acute were benign, special attention should be given co-infection order prevent possible severe cases.
On May 2017, a case of dengue serotype 1 was detected and confirmed through routine surveillance in traveler returning from Kribi, seaside town Southern Cameroon. This study aimed at confirming the circulation virus (DENV) Cameroon.A cross sectional carried out Londji near Kribi June 21-25, by joint team Centre Pasteur Cameroon Department Diseases, Epidemics Pandemics Control. Blood samples consented participants were collected tested for anti-D ENV IgM using an antibody capture...
Rift Valley Fever Phlebovirus (RVFV) and Crimean-Congo Hemorrhagic Orthonairovirus (CCHFV) specific antibodies had been documented among humans in urban settings of the southwestern northern Cameroon late 1980s. Recently, evidence for enzootic circulation RVFV was reported livestock both rural Cameroon. However, current estimates human exposure to CCHFV are still be Cameroon, especially areas. The aim this study assess seroprevalence Southeastern rain forest Using Enzyme-linked Immunosorbent...
With 762 laboratories, the Global Measles and Rubella Laboratory Network (GMRLN) is largest laboratory network coordinated by World Health Organization (WHO). Like Polio Network, GMRLN has multiple tiers, including global specialized regional reference national and, in some countries, subnational laboratories. Regional networks are supervised coordinators reporting to a coordinator at WHO headquarters. Laboratories have strong links disease control vaccination programs. The GMRLN's goal...
AbstractAbstractNo microfilariae are detectable in a significant percentage of those infected with the filarial worm Loa loa. While probability an individual becoming microfilaraemic is known to increase age, mechanisms underlying this trend not well understood. Epidemiological data from endemic village central Cameroon were therefore explored, attempt determine if, after taking into account any history filaricidal treatment, presence microfilaraemia was related his/her gender, and/or...
Abstract Background Annual community-directed treatment with ivermectin (CDTI) have been carried out since 1999 in the Lekie division (central region of Cameroon where most cases Loa -related post severe adverse events were reported) as part joined activities African Programme for Onchocerciasis Control (APOC) and Mectizan® Donation Program (MDP). As large-scale administration ivermetine was demonstrated to be an efficient means control loiasis transmission, it hypothesized that CDTI would...
Chikungunya virus (CHIKV) is a re-emerging arbovirus associated with sporadic outbreaks in Cameroon since 2006. Viral whole genomes were generated to analyze the origins of evolutionary lineages, potential emergence/re-emergence, and infer transmission dynamics recent CHIKV outbreak strains.Samples collected between 2016 2019 during screened for using reverse transcription PCR (RT-PCR), followed by genome sequencing positive samples.Three coding-complete obtained from samples, which belong...
Dengue and chikungunya are now widely distributed in Cameroon, but there is still not enough information on their prevalence different epidemiological settings. This study was undertaken to assess the of dengue both urban rural settings Cameroon using three diagnostic tools. From December 2019 September 2021, willing febrile (temperature >38 °C) outpatients visiting four healthcare facilities cities Yaoundé Dizangué were screened for dengue, chikungunya. Clinical features patient recorded...
As large-scale ivermectin distribution is becoming the mainstay of onchocerciasis control in Africa, issue its impact on local transmission increasing importance. The vector competence Simulium squamosum B severe focus Sanaga valley, Cameroon, was therefore investigated, by feeding 1320 flies 14 carriers Onchocerca volvulus microfilariae (mff). results enabled relationships between skin microfilarial load, intake flies, proportion and mean number ingested mff that succeed reaching fly's...
We have studied the impact of large-scale treatment with ivermectin on transmission loiasis in a forest village south Cameroon where was highly endemic, prevalence 30%. After one year parasitological and entomological surveillance without treatment, all consenting residents aged >5 years received 200 μg/kg every 3 months. For ethical reasons, interrupted after 2 years, but continued for 18 months end treatment. The reduced to <10% mean microfilaraemia decreased by 90% years. average...
Dog rabies is endemic in most African countries and the risk of human estimated to be high Cameroon according WHO estimations 2010. This study aimed describe circulation virus (RABV) among dogs southern regions from 2010 2013 a context, where mass vaccination campaigns are launched annually order control domestic animals including cats. From 2013, 93 animal specimens (dogs: 91, monkey: 1, pig: 1) originating were collected tested for at Centre Pasteur by fluorescent antibody test (FAT)...
