Obstructive sleep apnea (OSA) and viral respiratory infections are highly prevalent conditions in children and a major cause of respiratory morbidity in this age group. Severe viral respiratory infections are a known risk factor for pediatric OSA, which is primarily caused by hypertrophy of upper airway lymphoid tissues (adenoids and tonsils). This review examines recent progress in understanding early-life development of lymphoid tissues in the human upper airway, with a particular focus on how respiratory viruses may influence this process and contribute to OSA pathogenesis. It also explores the bidirectional relationship between OSA and severe viral infections, highlighting the need for ongoing monitoring and novel primary prevention strategies to address these interconnected conditions.

Since the emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the need for an effective vaccine has appeared crucial for stimulating immune system responses to produce humoral/cellular immunity and activate immunological memory. It has been demonstrated that SARS-CoV-2 variants escape neutralizing immunity elicited by previous infection and/or vaccination, leading to new infection waves and cases of reinfection. The study aims to gain into cases of reinfections, particularly infections and/or vaccination-induced protection.

The newly emerged variants of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) demonstrate resistance to present therapeutic antibodies as well as the capability to evade vaccination-elicited antibodies. JN.1 sublineages were demonstrated as one of the most immune-evasive variants, showing higher neutralization resistance compared to XBB.

Objectives: To evaluate the therapeutic effect of suraxavir marboxil (GP681, abbreviated as suraxavir) in adults with uncomplicated influenza.
Methods: We conducted a multi-center randomized, double-blind, placebo-controlled phase 2 trial in 18 Chinese centers. Participants had to be aged 18-65 years with positive influenza test, presenting with at least one influenza systemic and respiratory symptoms in at least moderate severity within 48 hours of onset.

Objectives: Acute respiratory infections (ARI) often occur in early childhood and are mostly self-limited. However, they impose a high socioeconomic burden and can be associated with chronic diseases later in life. To date, data on self-reported ARI beyond infancy are limited.

Background: Bordetella bronchiseptica is a primary pathogen in canine infectious respiratory disease (CIRD), or kennel cough, capable of independently causing respiratory illness and contributing significantly to co-infections with other viral and bacterial agents. Despite its critical role in disease transmission and persistence, the epidemiology of B. bronchiseptica in CIRD remains poorly understood.
