Although clinical forms are generally less severe in children than in adults, children nevertheless present polymorphous clinical forms and severe cases that can lead to death. Objective: To describe the clinical presentations found in the different waves of COVID-19, and to highlight the different factors of severity. Materials and Methods: We conducted a cross-sectional study with retrospective and prospective data collection which lasted 7 months (from November 2021 to June 2022) and covered a study period from 6 March 2020 to 22 June 2022, i.e. 27 months. All patients aged 0 to 18 years, suspected of having COVID-19, confirmed by real-time RT-PCR or an antigenic Rapid Diagnostic Test or antibody were included. These patients were to be managed in the Mother and Child Centre of the Chantal Biya Foundation, as well as in the Specialised Centre for the Management of COVID patients, annex number II of the Yaoundé Central Hospital. The results were analysed using IBM SPSS.23 software. Results: We included 163 patients in our study. No paediatric patients were registered during the 3<sup>rd</sup> wave. The mean age of the patients in the study population was 13 ± 5 years with extremes from 15 days to 18 years. We had a female predominance with a sex ratio of 0.83. The most common comorbidity was asthma. The first wave presented mainly with respiratory symptoms such as dry cough and signs of respiratory distress. The second wave presented mainly with digestive symptoms such as diarrhoea, abdominal pain and vomiting. The fourth wave presented with ENT signs such as sore throat, and rhinorrhea. Factors associated with severity were mainly age less than five years (OR = 17.69), vomiting (OR = 6.50), presence of comorbidities (OR = 3.39), and alteration of vital parameters such as bradypnoea (OR = 19.68), bradycardia (OR = 6.34), tachycardia (OR = 3.73), oxygen saturation Conclusion: Clinical presentations varied between waves and the main risk factor was age under 5 years. The fourth wave was less severe than the second wave, which in turn was less severe than the first. (4<sup>th</sup> <sup>nd</sup> <sup>st</sup>) which allows us to humbly recommend more screening for patients under 18 years of age with respiratory, ENT and digestive signs and special attention for those under 5 years of age.展开更多

This study aimed to assess the prevalence of these diseases and HIV among a young male population, according to region. Methods: This was a descriptive cross-sectional study conducted from 17 February to 31 March 2014 in the ten administrative regions of Cameroon. The study included male subjects of Cameroonian nationality aged at least 18 and at most 23, and living in the regions concerned. It excluded subjects that did not match the age, gender, and nationality criteria. For each subject, 10 ml of blood was collected in a dry tube. After centrifugation at 3000 RPM for 5 minutes, the serum was collected for the detection of viral infections. For subjects that tested positive, a confirmatory test was conducted. Results: In total, 4367 subjects were selected, with an average age of 20.46 (+/- 1.17) years. The prevalence of hepatitis B virus stood at 13.01% (with 95% CI: 12.03% - 14.05%). That of viral hepatitis C was 0.30% (95% CI: 0.17% - 0.52%). Co-infection with hepatitis B and C viruses was 0.05% (95% CI: 0.01% - 0.18%). The prevalence of HIV infection was 1.01% (95% CI: 0.74% - 1.36%). Conclusion: The overall prevalence of HBsAg in the population of young males is high. It tallies with the early vertical and horizontal modes of transmission that prevail in our environment.展开更多
