The Ministry of Health has also cautioned that the chances of respiratory illnesses due to the high risk of flash floods and the Saharan dust episodes, that may promote mould growth, potentially worsening asthma, allergies, and other respiratory conditions. Citizens have been urged to take preventative measures by ensuring good hygiene, proper ventilation, and limiting exposure to dusty conditions.
