A new wave of COVID-19, driven by the Omicron subvariants Nimbus (NB.1.8.1) and Stratus (XFG), is leading to a gradual increase in cases globally, with a notable impact on children. According to Dr. Süleyman Alpar of Memorial Bahçelievler Hospital, the current outbreak presents predominantly as an upper respiratory tract infection, with symptoms closely mirroring seasonal flu. The Nimbus variant is particularly distinguished by a uniquely severe “razor-like” sore throat.
Data from the World Health Organization and the United States indicate a rise in test positivity and emergency room visits among vulnerable groups, especially children aged 0-4, corresponding with the start of the school year. Despite this increase in cases, hospitalization and mortality rates have remained low. Due to significant symptom overlap with other respiratory viruses, international guidelines emphasize the necessity of diagnostic confirmation through PCR or rapid antigen testing rather than relying on clinical presentation alone. Special caution and vaccine booster doses are recommended for children with chronic illnesses or compromised immune systems.
