Background. The Coronavirus Disease 2019 (COVID-19) pandemic became much more severe in 2021. Healthcare students are a crucial population that needs to participate in disease preventive assistance and are very susceptible to COVID-19 exposure due to the specialized nature of their area of study. Knowledge, attitudes, and practices are important for protecting healthcare volunteer students against infection in COVID-19 sampling. Objectives. To better understand the knowledge, attitudes, and practices of COVID-19 infection control among the community sampling team student volunteers. Materials ..read more

Zoonoses caused by multiple etiological agents pose a serious threat to humans as well as animals globally. These diseases affect both the sexes, all age groups, in rural and urban settings, and in all seasons. Zoonotic diseases occur in sporadic as well as in epidemic form causing high morbidity and mortality. Most zoonoses involve multiple modes of transmission, such as ingestion, direct contact, inhalation, animal bite and others. Also, more than 60% of recently emerging viruses exhibit zoonotic characteristics, thereby posing a significant menace to global public health. The spread of thes ..read more

Context: In Cameroon, piroplasm infections have been reported among cattle, causing significant economic losses in the livestock industry. However, specific information about the epidemiology of piroplasm among cattle in Nde and Noun Divisions are limited. Aims: Highlight the prevalence of Piroplasm and the relationship between the blood density of Piroplasm and anaemia among cattle populations of Nde and Noun Divisions in the West region of Cameroon. Settings and Design: The present study was conducted during the rainy season from March to June 2022. Methods and Material: Blood samples from 5 ..read more

Background: This study aimed to determine the microbial diversity and Community Structure of Coastal water bodies from some cholera-prone communities in Rivers State. Methods: Water samples were collected from water bodies located in six different cholera prone coastal communities in Rivers state three times each with the determination of coordinates each time using Global Positioning System (GPS). At each collection point, in-situ physicochemical parameters of water sources were determined using H198194, H198195, and H198196 multiparameter meters (Hanna Instrument Inc, USA). The water samples ..read more

Background: Chikungunya is an emerging global threat because of the unprecedented magnitude of its spread and highly debilitating disease. Objective: This study was informed by the need to use serological methods to unmask the chikungunya virus (CHIKV) from suspected malaria patients. Methodology: The ELISA IgM and PRNT90 (nAb) were used to assess the presence of CHIKV antibodies. Findings: Of 530 patients, 129 (24.3%) had CHIKV IgM, 199 (37.5%) neutralizing antibody (nAb) and 23 (4.3%) IgM + nAb. Only 4.3% of the patients and 43.9% of the IgM negatives had CHIKV nAb indicating acute and past ..read more

Background: Non-communicable diseases (NCDs) have reached epidemic proportion among people living with HIV (PLHIV) and this could have a negative bearing on the quality of life and survival of these patients. The incorporation of a target specially dedicated to NCDs within the goal number 3 of the newly adopted Sustainable Development Goals indicates the importance the world now accords to the prevention and control of these diseases. Mobile phone technology is increasingly viewed as a promising communication channel that can be utilized for primary prevention of NCDs by promoting behavioural ..read more

The relevance of transplacental acquired malaria is still not clear in many malaria endemic areas. This study was designed to evaluate the prevalence, risk factors and antimalarial treatment outcomes of laboratory-confirmed congenital malaria cases in Douala. Methodology. This was a hospitalized-based cross-sectional study undertaken among under seven days neonates hospitalized between January 2018 and May 2018 in the neonatalogy units of three Douala-based hospitals in Cameroon. For each eligible neonate, maternal and perinatal data were collected. The newborn was immediately examined for phy ..read more

The Theory of urban endemo-epidemiogenesis is a general explanatory hypothesis of the processes of emergence and geographic spread of infectious diseases in the city. According to this theory, each city has an urban geosystem of endemo-epidemies structured in two hemispheres, which are in constant opposition or confrontation. The first one is the precursor-hemisphere that is composed to four specific systems: (1) the pathogen, (2) vulnerability, (3) classic itineraries of dissemination and (4) channels of dissemination systems. The second one is the resilient-hemisphere that is also composed t ..read more

Background: Measles, because of its burden of morbidity and mortality, is one of the most important diseases targeted by immunization. Caused by a virus, it is very contagious and therefore requires vaccination during the first year to avoid serious complications. Global death toll was over 140,000 persons in 2018. In recent years, measles cases have increased and outbreaks recorded due to declining vaccination coverage worldwide. Thus, countries that were previously declared measles-free and preparing to eliminate measles are still recording cases. This increase in measles incidence has also ..read more

Mosquitos continue to be insects of global attention for several centuries due to their ability to inhabit a wide range of ecological conditions that enable them to breed in diversified environments. The Anopheles species particularly the female mosquito is the main vector for malaria transmission in human. In Tanzania, for many years the control of malaria transmission is centered on attacking adult mosquitoes lagging behind the immature stages of the vector. Therefore, area- specific identification and characterization of mosquito breeding sites is important towards designing effective vecto ..read more
