Lessons learnt from the intense 2014 Chikungunya Epidemic in Grenada

OBJECTIVE: To present an overview of the lessons learnt from the fall 2014 outbreak of Chikungunya (CHIK) in Grenada. DESIGN AND METHODS: A review of newspaper articles, news reports and opinions of clinicians and policy makers on the impact and evolution of the CHIK outbreak in Grenada was conducted. RESULTS: CHIK outbreaks on small island developing nations are characterized by high attack rates. The speed of the spread of the virus is facilitated by the efficient domesticated diurnal vector species Aedes aegypti. Efforts to educate the public and to control this vector stretched resources. Clinical attack rates in the Grenada outbreak impacted manpower resources in every sector including clinical services. CONCLUSION: CHILK infected an estimated 60% of the population in just three months of intense transmission. The resulting morbidity meant that essential lessons were learnt. These included the need for a rapid response in educating the population on the mode of transmission of the virus and its prevention, the implementation of vector control and the demand for diagnostic tests. Essential services were short staffed. The need for an unprecedented rapid response and the impact of the CHIK outbreak in Grenada will be presented.
