we also had several cases of Dengue this year around Friends and also in the Family, Hydration is the keypoint what people need, and of course to go to the clinic right away. it takes around a week for the person to come back to powers.
Diagnosed Early Dengue is not a big Threat for Life.
If Symptoms let People assume there may be Dengue present, never take any kind of Tratment which involves Antibiotics, that would be a Danger, always go straight to a Clinic and let them run the Bloodtest.
2 weeks ago we feared my Wife has Dengue, luckily it wasn't, to await the Bloodtests Results too just 35 minutes to wait at Centro Medico Punta Cana.
also Public Clinics are used to treat Dengue, it is nothing rare on the Isle, more common than the Flu.
good luck for the lil one
