Nanotechnology and nanomedicine have excellent potential in dealing with a range of different health problems, including viruses, which are considered to be a serious challenge in the medical field. Application of nanobiotechnology could represent a new avenue for the treatment or disinfection of viruses. There is increasing concern regarding the control of coronaviruses, among these, Middle East respiratory syndrome coronavirus, severe acute respiratory syndrome coronavirus and severe acute respiratory syndrome coronavirus-2 are well known and dangerous examples. This article aims to provide an overview of recent studies on the effectiveness of nanoparticles as diagnostic or antiviral tools against coronaviruses. The possibilities of effectively using nanomaterials as vaccines and nanosensors in this field are also presented.

The transmission bottleneck, defined as the number of viruses shed from one host to infect another, is an important determinant of the rate of virus evolution and the level of immunity required to protect against virus transmission. Despite its importance, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission bottleneck remains poorly characterized. We adapted a SARS-CoV-2 reverse genetics system to generate a pool of >200 isogenic SARS-CoV-2 viruses harboring specific 6-nucleotide barcodes, infected donor hamsters with this pool, and exposed contact hamsters to paired infected donors, varying the duration and route of exposure.

Introduction: Incidences of infections with Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2) are still high and treatment guidelines lack specific recommendations for outpatients with Coronavirus-induced disease 2019 (COVID-19). Phytomedicine ELOM-080, an enhancer of mucociliary clearance (MCC), showed benefits as add-on therapy in hospitalised COVID-19 patients.
Methods: This randomised, double-blind, placebo-controlled proof-of-concept study investigated whether outpatients with mild to moderate acute symptomatic COVID-19 would benefit from a 14-day treatment with ELOM-080 with regard to potential early treatment effects on cough and further typical COVID-19 symptoms.

Background: Pediatric respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (LRTI) commonly requires hospitalization. The Clinical Progression Scale Pediatrics (CPS-Ped) measures level of respiratory support and degree of hypoxia across a range of disease severity, but it has not been applied in infants hospitalized with severe RSV-LRTI.
Methods: We analyzed data from a prospective surveillance registry of infants hospitalized for RSV-related complications across 39 U.

COVID-19 severely impacts children in India, with many developing severe pneumonia or multisystem inflammatory syndrome (MIS-C). Concurrently, non-COVID-19 respiratory viruses causing community-acquired pneumonia (CAP) have resurged. These conditions present similarly, challenging accurate diagnosis.

In 2024, several important innovations have enriched the management of respiratory diseases, including pulmonary hypertension, tuberculosis, COPD, and obstructive sleep apnea syndrome (OSAS). Notable advancements include the introduction of sotatercept in Switzerland for pulmonary arterial hypertension and mediastinal cryobiopsies, reflecting a shift toward more personalized medicine. Meanwhile, biologic therapies for COPD offer promising perspectives, and a potential path is emerging for shortening the treatment of certain forms of tuberculosis.
