Air pollution ‘likely’ to cut COVID-19 survival: experts

PARIS: Air pollution from petrol and diesel vehicles is likely to increase mortality from the novel coronavirus in cities, public health experts told AFP Monday.

The European Public Health Alliance (EPHA) warned that dirty air in urban areas that causes hypertension, diabetes and other respiratory illness could lead to a higher overall death toll from the virus currently sweeping the world.

Emissions from petrol and diesel engines were still at “dangerous” levels that could imperil the most vulnerable during this and future pandemics, said the European Respiratory Society (EPS), which is a member of the EPHA.

“Patients with chronic lung and heart conditions caused or worsened by long-term exposure to air pollution are less able to fight off lung infections and more likely to die,” EPS member Sara De Matteis said. “This is likely also the case for COVID-19,” added de Matteis, who is also an associate professor in occupational and environmental medicine at Italy´s Cagliari University.

The virus has so far infected more than 168,000 people and killed over 6,500 worldwide. Several European nations have implemented unprecedented measures to prevent the spread of the disease and allow health systems to treat patients. While there is currently no proven link between COVID-19 mortality and air pollution, one peer-reviewed study into the 2003 SARS outbreak showed that patients in regions with moderate air pollution levels were 84 percent more likely to die than those in regions with low air pollution. COVID-19 is similar to SARS and can cause respiratory failure in severe cases. Mortality data for COVID-19 is incomplete, but preliminary numbers show the majority of patients who die are elderly or have pre-existing chronic conditions such as heart or lung disease. According to the European Environment Agency, air pollution leads to around 400,000 early deaths across the continent annually, despite European Union air quality directives.
