The Ministry of Health, Wellness, and Elderly Affairs is ramping up public awareness efforts as measles cases rise significantly across the Americas.
Saint Lucia has not reported a measles case in decades. However, according to the World Health Organisation (WHO), global measles cases surged by 20 per cent in 2023, totaling 10.3 million cases and over 100 000 deaths, predominantly among children under five.
The Pan American Health Organisation (PAHO) reported 268 confirmed measles cases in Argentina, Canada, Mexico, and the United States as of February 21, 2025—a sharp increase from the 60 cases recorded during the same period in 2024.
National Epidemiologist, Dr Michelle Francois highlighted the urgency of preventive action.
“Measles is one of the most contagious viral diseases, capable of spreading rapidly through airborne transmission and remaining infectious for up to two hours in enclosed spaces. Given the rising global cases, Saint Lucia must act swiftly to prevent an outbreak by maintaining high vaccination coverage,” she noted.
Measles spreads through respiratory droplets, and a single case can infect up to 20 unvaccinated individuals. Early symptoms resemble the common cold—fever, runny nose, and cough—before progressing to red, watery eyes, white spots inside the cheeks, and a widespread rash. Due to its rapid transmission, even one case can pose a serious public health threat, particularly in communities with declining immunisation rates.
Dr Francois stressed the need for a strong immunity action plan.
“Saint Lucia has not reported a measles case in decades, but declining immunisation rates put us at risk. A single imported case from an affected region could trigger an outbreak if community immunity falls below the 95 per cent threshold,” she explained.
Since there is no specific treatment for measles, vaccination remains the most effective preventive measure. The Measles, Mumps, and Rubella (MMR) vaccine) is available free of charge at all wellness centres across the island. Full immunity requires two doses, administered at 12 months and 18 months of age.
The Ministry of Health urges the public to take the following precautions:
- Ensure children receive both doses of the MMR vaccine on schedule.
- Verify vaccination status at the nearest Wellness Centre if uncertain.
- Stay informed about measles outbreaks before travelling.
- Monitor for symptoms, especially after contact with individuals from affected areas.
- Practise good hygiene, including frequent handwashing and proper respiratory etiquette.
