श्रीलंका में जनवरी के महीने में डेंगू के लगभग 5000 मामले सामने आए
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, orange-colored “fascicle”, which while not feeding, is covered in a soft, pliant sheath called the "labellum”, which retracts as the sharp stylets contained within pierce the host's skin surface, as the insect obtains its blood meal. The orange color of the fascicle is due to the red color of the blood as it migrates up the thin, sharp translucent tube. 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. As the primary vector responsible for the transmission of the Flavivirus Dengue (DF), and Dengue hemorrhagic fever (DHF), the day-biting Aedes aegypti mosquito prefers to feed on its human hosts. Ae. aegypti also plays a major role as a vector for another Flavivirus, "Yellow fever". Frequently found in its tropical environs, the white banded markings on the tarsal segments of its jointed legs, though distinguishing it as Ae. aegypti, are similar to some other mosquito species. Also note the lyre-shaped, silvery-white markings on its thoracic region as well, which is also a determining morphologic identifying characteristic.

This female’s abdomen had become distended due to the blood meal she was ingesting, imparting the red coloration to her translucent abdominal exoskeleton.

श्रीलंका में जनवरी के महीने में डेंगू के लगभग पांच हजार मामले सामने आए हैं। इससे दो लोगों की मृत्यु भी हो गई है। राष्ट्रीय डेंगू नियंत्रण इकाई की रिपोर्ट के अनुसार डेंगू के कुल 4 हजार 9 सौ 43 मामले दर्ज किए गए हैं।

 

देश भर में डेंगू के 16 उच्च जोखिम वाले क्षेत्रों की पहचान की गई है। गम्पाहा जिले में सबसे अधिक 7 सौ 64, कोलंबो में 6 सौ 74 और कोलंबो नगर परिषद क्षेत्र में 6 सौ आठ मामले दर्ज किए गए।

 

    अधिकारियों ने लोगों से डेंगू के प्रसार को रोकने के लिए निवारक उपाय करने का आग्रह किया है। 2024 में, श्रीलंका में डेंगू के लगभग 50 हजार मामले दर्ज किए गए थे जिनमें से 24 लोगों की मौत हो गई थी।
