2006 Prof. Frank Hadley Collins, Dir., Cntr. for Global Health and Infectious Diseases, Univ. of Notre Dame This 2006 photograph depicted a female Aedes aegypti mosquito while she was in the process of acquiring a blood meal from her human host, who in this instance, was actually the biomedical photographer, James Gathany, here at the Centers for Disease Control. You?ll note the feeding apparatus consisting of a sharp, ?fascicle?, which while not feeding, is covered in a soft, pliant sheath called the "labellum?, which is seen here retracted, as the sharp ?stylets? contained within pierced the host's skin surface, as the insect obtained its blood meal. The fascicle is composed of a pair of needle-sharp stylets. The larger of the two stylets, known as the "labrum", when viewed in cross-section takes on the shape of an inverted "V", and acts as a gutter, which directs the ingested host blood towards the insect's mouth. This female?s abdomen had become distended due to the blood meal she was ingesting, imparting the red coloration to her translucent abdominal exoskeleton. DF and DHF are primarily diseases of tropical and sub-tropical areas, and the four different dengue serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), are maintained in a cycle that involves humans and the Aedes mosquito. However, Aedes aegypti, a domestic, day-biting mosquito that prefers to feed on humans, is the most common Aedes species. Infections produce a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease. Important risk factors for DHF include the strain of the infecting virus, as well as the age, and especially the prior dengue infection history of the patient.

THE BOTTOM – The government of Saba has advised that dengue fever has now been identified on the island. The Public Health Department is issuing a public advisory to heighten awareness and encourage preventive measures. 

Vector control efforts have been ongoing to eliminate potential mosquito breeding sites. It is crucial for individuals to remain vigilant and contribute to the prevention of dengue transmission. 

Recommendations from the Government include installing or repairing window and door screens, utilizing air conditioning, addressing indoor water-holding items, considering insecticide use, wearing protective clothing, and seeking medical attention if symptoms like high fever, severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands, or rash develop. 

Symptoms

For those experiencing symptoms, Saba Cares can be contacted at +5994163288. This collaborative effort aims to curb the spread of dengue and protect the community’s well-being.

The arrival of Dengue Fever to the island is no surprise, as various cases had already been identified in both St. Maarten and St. Eustatius.
