“…Three parasite species were predominantly diagnosed in pupils, namely Ascaris lumbricoides (16.41%), Schistosoma mansoni (14%), and Hymenolepis nana (6.53%). This observation was also made for the first species by, among others, Goodman et al [24] in Zanzibar, Hamit et al [25,26] in N'Djaména, Zephania et al [27] in Cameroon, Oyono et al [28] in the central Cameroon region, and Leta et al [29] in Ethiopia. This high infestation rate of Ascaris lumbricoides in our study confirms that it is one of the most widespread intestinal helminths in the world [3,5,7].…”

Aims: The objective of this study was to determine the epidemiological profile of intestinal helminthiases in school children in the Sahelian and Sudanian zones of Chad. Study Design: Cross-sectional and descriptive. Place and Duration of Study: September 2021 to February 2022 in two of Chad's three ecological zones: the Sudanian and Sahelian zones. Methodology: A total of 1408 stool samples were collected from school children (aged from 5 to 18 years) in 19 schools; 13 of which were in the Sudanian zone and 6 in the Sahelian zone. The analysis of these samples was carried out by the Kato-Katz method, for the detection and quantification of intestinal helminths eggs. Results: Analysis of these samples revealed the presence of 9 helminths taxa, with an overall infestation rate of 35.87% in both zones. Ascaris lumbricoides (16.41%), Schistosoma mansoni (14.00%) and Hymenolepis nana (6.53%) were the most common helminths found. Pupils in the Sudanian zone were relatively more infested than those in the Sahelian zone, except for Taenia saginata and Ascaris lumbricoides which were more often found in the Sahelian zone. With the exception of Enterobius vermicularis, no other difference in infestation rates was observed between age groups. By gender, the only significant difference in infestation rates was noted for Schistosoma mansoni for which girls were more parasitized. Conclusion: This study showed a high prevalence of these parasitoses in Chad and that poor hygiene favors the endemicity and persistence of these helminthiases; it also points to the need for a national helminthiases control program.

“…In fact, in Chad, there are localities or schools that do not benefit from chemoprevention, while others benefit regularly. However, Oyono et al [28] recommend that strategies to control these diseases by deworming children in schools be regular and targeted.…”

Introduction. Soil-transmitted helminths (STH) remain a public health problem worldwide especially in low-income countries. Soil-transmitted helminths are known to affect both growth and haemoglobin levels. In this study, we determine the prevalence of intestinal parasites and explored its association with anaemia in school-aged children (SAC). Methodology. A cross-sectional study was carried out amongst pupils selected from 18 primary schools in four communities of the North West Region. Stool samples were examined using direct wet mount and formol-ether concentration techniques, while finger prick was performed for the measurement of haemoglobin with a haemoglobinometer. Results. The results showed significant variation of STHs, intestinal protozoan prevalence, and anaemia between age, sex, and communities. The prevalence of Ascaris lumbricoides, Trichuris trichiura, and hookworms was 15.1%, 0.8%, and 2%, respectively, with an overall STH prevalence of 18.3% across the four communities. Soil-transmitted helminths were more prevalent in Mbessa (30.2%) in comparison to Nkor (26.7%), Djottin (17.5%), and Kumbo (9.6%) communities. The prevalence of Entamoeba histolytica/dispar was 25.4% and Giardia duodenalis (6.9%), with an overall intestinal protozoa prevalence of 31% across the four communities. The prevalence of anaemia in the study population was 23.1%. Conclusion. Soil-transmitted helminths, intestinal protozoan infections, and anaemia are prevalent in the study area. Anaemia was observed to be associated with STH, intestinal protozoa, and the communities under study. This study recommends continuous deworming and health education on personal sanitation and environmental sanitation.

Burden of mosquito-borne diseases across rural versus urban areas in Cameroon between 2002 and 2021: prospective for community-oriented vector management approaches

et al. 2023

Background Over the past two decades, Cameroon has recorded one of the highest rates of urban population growth in sub-Saharan Africa. It is estimated that more than 67% of Cameroon's urban population lives in slums, and the situation is far from improving as these neighbourhoods are growing at an annual rate of 5.5%. However, it is not known how this rapid and uncontrolled urbanization affects vector populations and disease transmission in urban versus rural areas. In this study, we analyse data from studies conducted on mosquito-borne diseases in Cameroon between 2002 and 2021 to determine the distribution of mosquito species and the prevalence of diseases they transmit with regards to urban areas versus rural areas. Methods A search of various online databases, such as PubMed, Hinari, Google and Google Scholar, was conducted for relevant articles. A total of 85 publications/reports were identified and reviewed for entomological and epidemiological data from the ten regions of Cameroon. Results Analysis of the findings from the reviewed articles revealed 10 diseases transmitted by mosquitoes to humans across the study regions. Most of these diseases were recorded in the Northwest Region, followed by the North, Far North and Eastern Regions. Data were collected from 37 urban and 28 rural sites. In the urban areas, dengue prevalence increased from 14.55% (95% confidence interval [CI] 5.2–23.9%) in 2002–2011 to 29.84% (95% CI 21–38.7%) in 2012–2021. In rural areas, diseases such as Lymphatic filariasis and Rift valley fever, which were not present in 2002–2011, appeared in 2012–2021, with a prevalence of 0.4% (95% CI 0.0– 2.4%) and 10% (95% CI 0.6–19.4%), respectively. Malaria prevalence remained the same in urban areas (67%; 95% CI 55.6–78.4%) between the two periods, while it significantly decreased in rural areas from 45.87% (95% CI 31.1–60.6%) in 2002–2011 to 39% (95% CI 23.7–54.3%) in the 2012–2021 period (*P = 0.04). Seventeen species of mosquitoes were identified as involved in the transmission of these diseases, of which 11 were involved in the transmission of malaria, five in the transmission of arboviruses and one in the transmission of malaria and lymphatic filariasis. The diversity of mosquito species was greater in rural areas than in urban areas during both periods. Of the articles reviewed for the 2012–2021 period, 56% reported the presence of Anopheles gambiae sensu lato in urban areas compared to 42% reported in 2002–2011. The presence of Aedes aegypti increased in urban areas in 2012–2021 but this species was absent in rural areas. Ownership of long-lasting insecticidal nets varied greatly from one setting to another. Conclusions The current findings suggest that, in addition to malaria control strategies, vector-borne disease control approaches in Cameroon should include strategies against lymphatic filariasis and Rift Valley fever in rural areas, and against dengue and Zika viruses in urban areas.
