Dust from North Africa is crossing mainland Portugal this Monday and Tuesday, with the Algarve expected to be one of the most affected regions, along with Lisbon, the Tagus Valley, and Alentejo. The phenomenon results from an air mass carrying suspended dust from African deserts, which should cause a situation of poor air quality associated with increased concentrations of inhalable particles (PM10) of natural origin in the atmosphere.
The Directorate-General for Health issued a statement warning about the risks of this situation, especially for vulnerable groups such as children, elderly people, and people with chronic respiratory problems, such as asthma, and cardiovascular patients. The health authority recommends that the general population avoid prolonged efforts, limit outdoor physical activity, and stay away from risk factors such as tobacco smoke and irritant products.
Regarding the most vulnerable groups, the DGS advises that, whenever possible, they remain inside buildings with closed windows. Chronic patients should continue to maintain their ongoing medical treatments and, in case of worsening symptoms, contact the Linha Saúde 24 through the number 808 24 24 24 or seek care at a health facility. For more information on air quality, the DGS refers to the APA website and the QualAr App.
