The Ministry of Health, Environment and Sustainability (MHES) and the Public Health Department (PHD) are advising residents to take precautions to protect themselves from the effects of forecasted Saharan dust. The Cayman Islands National Weather Service (CINWS) is likely to issue a Dust Alert on Friday 10 July.
Saharan dust is a mixture of dust and sand that travels thousands of miles from the Sahara Desert to the Caribbean each year. The Saharan dust, coupled with the El Niño conditions, means that the Atlantic basin is expected to see below-average tropical activity through the end of the season.
Saharan dust events can reduce air quality and affect respiratory health, particularly among vulnerable individuals. Symptoms associated with exposure may include coughing, wheezing, sore throat and shortness of breath.
Most people may experience only mild symptoms, but young children, older adults and persons with asthma or other chronic respiratory conditions are at increased risk.
Chief Medical Officer Dr. Hilary Wolf, said: “Saharan dust is expected to be a returning feature throughout this summer. As such, we continue to advise people with respiratory conditions such as asthma, as well as children, seniors and other vulnerable adults to take precautions during Dust Alert periods. Anyone experiencing worsening respiratory symptoms should contact their healthcare provider.”
Based on information provided by the Cayman Islands National Weather Service, the effects of the dust cloud are expected to begin on Friday evening and persist through Sunday.
MHES and PHD are issuing the following public health guidance:
General public
· Limit time outdoors, particularly during periods of high dust concentration.
· Keep doors and windows closed to reduce dust entering homes and buildings.
· Use air conditioners on recirculation mode or air purifiers, if available.
· Wear long-sleeved clothing and protect eyes from irritation.
· Wash hands regularly and avoid touching eyes.
· Monitor for new or worsening symptoms and seek medical advice if necessary.
Persons with asthma or other respiratory illnesses
· Remain indoors where possible and use air conditioning on recirculation mode.
· Ensure reliever inhalers and medications are readily available.
· Contact a healthcare provider if symptoms worsen.
Summer camps and workplaces
· Limit outdoor activities, including sports and prolonged breaks.
· Keep windows closed where practical.
· Inform parents and caregivers of measures being taken to protect vulnerable children.
MHES and PHD will continue to work closely with CINWS to monitor conditions and provide updates as necessary. Residents are encouraged to follow official government channels for the latest information.
