The aim of this study was to investigate knowledge on Simian Orthopoxvirosis or Monkeypox in 180 people (129 males and 51 females) using the stratified probability sampling method. The majority of the respondents were (are): 35-50 years old (45.00%), with secondary education (43.33%), farmers (40.56%) and married (80.00%). The disease appears every year, thus demonstrating its endemic nature (98.33% of the respondents); 58.3% of the respondents said that the disease appears very often during the dry season, on the contrary, 40% of the respondents said that the disease appears during the rainy season. However, 1.7% of respondents said that the disease occurs every other season. The majority of respondents (81.1%) said that the cause of the disease is the consumption of bush meat, followed by wild vegetables (3.3%), fish (2.8%), livestock (2.2%) and caterpillars (1.7%) respectively. 65.2% of the respondents use Manihot esculenta to treat the disease locally, and followed by the leaves and wine of Raphia sese (13%), Morinda morindoides (13%) and Myrianthus arboreus (8.7%). Between January 17 and September 10, 2020, 40 cases of monkey pox were admitted to HGR of Businga (Maximum age: 42 years, minimum age: 1 year, average age: 13.3 years). 28 patients were male and 12 female. It is therefore advisable that surveillance be organized in wild animals and bush meat exposed on the market to ensure that they are not contaminated with Monkeypoxvirus. It is thus needed to establish a veterinary laboratory in Nord-Ubangi Province.

Aims of the Study: To identify plant species traditionally used to treat anemia in Yakoma territory and to evaluate their chemical composition. Place and Duration: Yakoma Territory (survey) and University of Kinshasa (Phytochemical study), from August and October 2019. Methods: Ethnobotanical survey according to the "snowball" sampling technique among traditional healers (based on the free consent of the respondents), chemical analyses of plant materials (chemical screening, TLC, phytomarkers content, minerals composition) according to standard methods. ED-XRF was used for mineral analysis. Microsoft Excel version 2010, Origin version 8.5 Pro and IBM SPSS statistics version 20 software packages were used for data processing and analysis. Results and Discussion: The survey showed that 18 plant species are traditionally used by Ngbandi traditional healers to treat anemia in Yakoma territory. They belong to 16 families and 17 genera. The most used organs are the leaves (68.4%) and the roots (10.5%). Decoction and infusion are the most used mode of preparation (33.3% each), followed by cooking (22.2%) and maceration (11.1%). The oral route (77.8%) is the most used mode of administration followed by the enema (16.7%) and the anal route (5.6%). Morphological types consist of herbs and trees                  (33.3% each) and shrubs and lianas (16.7% each). The biotope types consist of forest                         plants (44.4%), cultivated plants/Crops (38.9%), marshy ground plants (11.1%) and ruderal plants (5.6%). These plants belonging to five biological types: erected therophytes (44.4%), mesophanerophytes (27.8%), microphanerophytes and climbing phanerophytes (11.1% each) and lianescent phanerophytes (5.56%). These anti-anemic plant species are mostly Pantropical and Afro-tropical (39% of species each) followed by Guineo-Congolese (17% of species) and American (5%). Chemical analysis revealed the presence of alkaloids, anthocyanins, flavonoids, anthraquinones and terpenoids and various minerals including iron, zinc, copper, calcium, magnesium and manganese. Conclusion: In the current state of knowledge, the survey of anemic plants from this part of the Democratic Republic of the Congo is reported for the first time.

Household solid waste management is a crucial issue for environmental and human health. The purpose of this study was to conduct a survey on household solid waste management in Gbado-Lite (Nord-Ubangi) in the Democratic Republic of Congo (DRC). A household solid waste survey was conducted in 5 neighborhoods of the city of Gbado-Lite in northern DRC from July to August. Data collection was made possible by stratified probability sampling and direct observations. The results of this study revealed that the main informants (75%) were women and 68% of the respondents were in the 18-35 age group. The main socio-cultural groups in the study area are the Ngbadi (55%) and Ngbaka (16%). In addition, 74% of respondents have secondary education and their main sources of income are commerce (25%), the civil service (20%) and the household (13%). Also, the main solid household wastes identified were organic materials (44%) and packaging (25%); the majority (56%) of respondents did not have garbage cans and used plastic buckets without lids as their main garbage can (75%). Almost all (98%) of the waste does not undergo primary separation. The main waste disposal methods used by households are: landfill (43.87%), abandonment on public land (30.62%) and incineration (18.36%). Finally, the main harms of waste reported are: typhoid fever (29%), malaria (25%) and mosquito proliferation (24%). It is therefore desirable that a public sanitation service be set up in Gbado-Lite to enable households to manage their solid waste properly and thus protect the urban environment and human health.

Democratic Republic of the Congo is a real reservoir of medicinal plants. These plants play a major role in the treatment of certain common pathologies in tropical regions. The aim of this study was to list the ethnomedical uses of Uvariodendron molundense, a medicinal and aromatic plant from the Ubangi ecoregion. The ethnobotanical survey was carried out in Gbado-Lite with 200 people using stratified probability sampling. The respondents were interviewed individually on the basis of free consent. The study revealed that the majority of respondents were men (72%) and had a secondary education (37%), followed respectively by illiterates (34%) and those with a primary education (28%), and finally, university graduates represented only 1% of the respondents. 83% of the respondents were farmers, while 79% of the respondents were married. The leaf is the most used organ (81%) followed by stem and root bark. U. molundense is used both as food and medicine. The plant treats eight diseases (pain, malaria, cold, hypertension, gastritis, infection, headache and rheumatism). The calculated value of the informant consensus factor is 0.96 and indicates that there is a high degree of consensus among informants regarding the use of U. molundense against these diseases in Gbado-Lite. Decoction is the most commonly used method of preparation (89%) and 50% of the respondents stated that the species is currently not very abundant, while 31% of the respondents felt that the plant was rare. The calculated value of the vulnerability index shows that U. molundense is very vulnerable in its natural environment (Iv ˃ 2.5).
