The cytomegalovirus is an infectious pathogen that causes a disease that can cause major difficulties in infants, allograft recipients, and people with any type of immunodeficiency. Because of their exposure to contaminating elements, developing countries are the most afflicted, with a prevalence of 97 percent in Cameroonian adults. It's an illness with a high cumulative incidence for which paediatric epidemiological data is scarce. Furthermore, the efficacy of measures to prevent transmission is poorly understood. The goal of this study was to determine the prevalence of anti-cytomegalovirus antibodies among newborns in order to provide better prenatal care. Methods: From January to May 2015, a prospective cross-sectional study with a descriptive goal was undertaken at the Chantal Biya Foundation's Mother and Child Centre in Yaoundé. The data was collected using a technical form that included demographic information and an Immunoglobulin G ELISA type serological test to assess the children's serological status. Results: We chose 188 children aged 0 days to 12 years from our study population, with an average age of 3 ± 4 years. CMV was found to be present in 66% of the people in our research. Between the ages of 0 and 24, the prevalence was high and constant.After a drop in prevalence between 25 and 36 months, the prevalence of CMV steadily increased from 43.5 to 77.8% between 25 and 12 years of age. Apart from age, no other factor was discovered to predispose to HIV infection. Conclusion: The prevalence of cytomegalovirus in children aged 0-12 years in our population was high and increased with age.

To describe the clinical features at time of testing and explore factors associated with SARS-CoV-2 infection and pre-symptomatic cases in Cameroon.Data was collected on people in Cameroon who participated in COVID-19 testing by real-time reverse transcriptase-polymerase chain reaction between 1 March and 5 October 2020. After descriptive analysis, multivariate logistic regression was used to identify factors associated with SARS-CoV-2 infection and pre-symptomatic cases.Of 85 206 test participants, 14 863 (17.4%) were infected with SARS-CoV-2. The median age for cases was 38.4 years (interquartile range 29.6-49.4); 6.1% were aged19 years, and 6.3% were ≥65 years. Of these cases, 46.5% had at least one symptom/sign with a median time from illness onset to testing of 6 days (interquartile range 3-9). Cough (64.2%), headache (46.5%), fatigue/malaise (46.0%), shortness of breath (30.6%) and myalgia/arthralgia (25.6%) were the most commonly observed symptoms/signs. Pre-symptomatic SARS-CoV-2 infection was associated with age50 years, being male and absence of comorbidities.This study provides a comprehensive summary of the early clinical profile of SARS-CoV-2 infection during the first wave of COVID-19 in Cameroon, which was dominated by pre-symptomatic illness. These findings would be helpful for SARS-CoV-2 surveillance and control at a regional level.
