The impact of anthropogenic climate change on pediatric viral diseases

The adverse effects of climate change on human health are unfolding in real time. Environmental fragmentation is amplifying spillover of viruses from wildlife to humans. Increasing temperatures are expanding mosquito and tick habitats, introducing vector-borne viruses into immunologically susceptible populations. More frequent flooding is spreading water-borne viral pathogens, while prolonged droughts reduce regional capacity to prevent and respond to disease outbreaks with adequate water, sanitation, and hygiene resources. Worsening air quality and altered transmission seasons due to an increasingly volatile climate may exacerbate the impacts of respiratory viruses. Furthermore, both extreme weather events and long-term climate variation are causing the destruction of health systems and large-scale migrations, reshaping health care delivery in the face of an evolving global burden of viral disease. Because of their immunological immaturity, differences in physiology (e.g., size), dependence on caregivers, and behavioral traits, children are particularly vulnerable to climate change. This investigation into the unique pediatric viral threats posed by an increasingly inhospitable world elucidates potential avenues of targeted programming and uncovers future research questions to effect equitable, actionable change. IMPACT: A review of the effects of climate change on viral threats to pediatric health, including zoonotic, vector-borne, water-borne, and respiratory viruses, as well as distal threats related to climate-induced migration and health systems. A unique focus on viruses offers a more in-depth look at the effect of climate change on vector competence, viral particle survival, co-morbidities, and host behavior. An examination of children as a particularly vulnerable population provokes programming tailored to their unique set of vulnerabilities and encourages reflection on equitable climate adaptation frameworks.

[Noninvasive ventilation in pediatric acute respiratory failure]

Noninvasive ventilation (NIV) may be used to treat pediatric acute respiratory failure. Recent improvements in ventilator technology and availability of nasal and full face masks for infants and children have simplified the use of NIV even in the smallest children. Mainly patients with hypercapnic respiratory failure may benefit from noninvasive ventilation. There is some evidence available that supports the use of NIV in viral bronchiolitis, asthma and acute on chronic respiratory failure in patients with neuromuscular or chronic pulmonary disease. Furthermore, noninvasive ventilation is beneficial during prolonged weaning from invasive ventilation and to treat upper airway obstructions. Children suffering from hypoxic respiratory failure, such as community-acquired pneumonia and acute respiratory distress syndrome do not benefit from NIV. Due to possibly relevant side effects and the possibility of rapid deterioration in gas exchange in failure of NIV, invasive ventilation should be readily available; therefore, treatment with noninvasive ventilation for acute respiratory failure in children should be initiated on the pediatric intensive care ward.
