Respiratory infections are widespread mainly affecting the upper respiratory tract and are normally self-limiting and easily tolerated. However in high-risk asthma patients respiratory tract infections can cause severe symptoms and airflow restriction, which can be severe. Furthermore, when respiratory infections directly infect the lung, morbidity and even death can occur.

With the on-going coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 the extent, effect, and contributions of respiratory infections to impairments in life-sustaining function of the lungs have been profoundly and severely illustrated (SARS-CoV-2).The breakthroughs that have resulted have contributed to higher basic insights, increased identification and comprehension of the impact of respiratory infections on the lung, and most importantly improved patient outcomes.

RSV and rhinoviruses are two respiratory infections that are directly associated to asthma development and pathophysiology. RSV and RV can produce wheezing episodes in children. Although it is unknown whether this early-life infection-induced wheezing events contribute to or cause the eventual development of asthma their discovery highlights the importance of respiratory tract infections in the development of asthma and has identified other key risk factors such as genetic determinants environmental factors and immune inflammatory generation in determining links to asthma pathogenesis.

In contrast the remarkable link between viral respiratory infections and asthma relapses is well recognized how respiratory viruses might influence the production of airway inflammation. Therapeutic targets for this virus-induced inflammation may allow for more precise therapy. The effects of respiratory infections on lung health are mostly governed by functions of the host's immune-protective response. Patients with Primary Immune Deficiency Disorders (PIDDs) are especially vulnerable to severe effects from respiratory infections.

Which frequently act as a triggering event for the existence of impaired immunological function. The use of new born screening has aided in the identification of at-risk new-born for PIDDs, hence preventing unanticipated severe respiratory illnesses caused by early-life infections. Identifying and diagnosing immune deficits linked with pulmonary infections has also led to increased understanding of the specificities of protective immune function and guidance for improving treatment options.

The continuing COVID-19 pandemic has highlighted the significance vulnerability and fatal effects of SARS-CoV-2 respiratory infection. This effort has resulted in the development of molecular diagnostics and innovative vaccination strategies for more accurate and effective disease prevention. Patients with asthma have been of special interest in the COVID-19 pandemic because to their history of vulnerability to other viral illnesses. If this causal link could be demonstrated possible guidelines to avoid asthma or at the very least change components of illness manifestation may be produced.

RSV affects the airway epithelium causing changes in pulmonary function. An RSV infection is also related with a shift in the immune response toward type 2 inflammations as well as increased IL-17 A production a pattern of airway inflammation connected to asthma. However, it is possible that additional variables in addition to the infecting virus determine or contribute to the ensuing pattern of airway dysfunction. The pattern of the existing or changed micro biota that defines an eventual long-term response as well as host genetic variables has been of special interest. Although it is unclear if RSV causes asthma, "clinical care will need to continue to focus on effective treatment of pediatric wheezing diseases until there are validated prevention strategies."
