Özet

Background: The prevalence of meningococcal carriage and serogroup distribution is crucial for assessing the epidemiology of invasive meningococcal disease, forecasting outbreaks and formulating potential immunization strategies. Following the meningococcal carriage studies conducted in Turkey in 2016 and 2018, we planned to re-evaluate meningococcal carriage in children, adolescents and young adults during the COVID-19 pandemic period. Methods: In the MENINGO-CARR-3 study, we collected nasopharyngeal samples from 1585 participants 0-24 years of age, across 9 different centers in Turkey. We used polymerase chain reaction and serogroup distribution to determine how common it is for people to carry Neisseria meningitidis. Results: The overall meningococcal carriage rate was 8.5% (n = 134). The serogroup distribution was as follows: serogroup A, 6%; serogroup B, 30.6%; serogroup W, 12.7%; serogroup Y, 3.7%; serogroup X, 1.5% and nongroupable as 45.5%. The highest carriage rate was found in 15-17-year-old adolescents (24.1%, 17.9%, and 20.2%, respectively). The carriage rate was higher among participants who had a previous COVID-19 infection (P = 0.05; odds ratio: 1.95; 95% confidence interval: 1.11-3.44). The nasopharyngeal carriage rate was also higher than in the 2016 and 2018 studies (8.45% vs. 6.3% and 7.5%, respectively), and the most prevalent groupable serogroup was B during this study period, followed by serogroup W in 2016 and serogroup X in 2018. Conclusions: The present study found that meningococcal carriage was higher during the post-COVID-19 pandemic period, especially in adolescents and young adults. Severe acute respiratory syndrome coronavirus-2 virus itself and/or pandemic mitigation strategies may affect both meningococcal carriage and serogroup distribution. Serogroup distribution varies between years, and further immunization strategies, including adolescent immunization, may play a role in controlling invasive meningococcal disease.
