NEW DELHI, November 12 (Prensa Latina) – India registered more than 83,000 cases of dengue fever as of last October, according to data released today by the National Center for Control of Vector-Borne Diseases.
The continued spread of the disease, with last month at its worst with 20,000 cases, is being attributed to a late retreat of the rainy monsoon season, according to the Down To Earth portal.
In India, the number of months suitable for dengue transmission by Aedes aegypti and Aedes albopictus mosquitoes increased to 5.6 months per year.
Currently, Aedes aegypti is widespread on the country’s south and east coasts, north-eastern states and northern plains, while Aedes albopictus dominates the east and west coasts, north-eastern states and lower Himalayas.
Researchers predict the spread of Aedes aegypti in the hot, arid regions of the Thar Desert, also known as the Great Indian Desert, in north-west India and east Pakistan, and Aedes albopictus in the frigid high Himalayas as a result of climate change. . .
Dengue cases in India usually appear after the July and August monsoons and last until late November, sometimes even December.
The duration of the outbreak depends on rainfall and temperature, with 30-32 degrees being favorable for dengue development.
Coastal areas of India continue to be the center of dengue cases, but with urbanization and climate change, the prevalence of this infection is expected to increase in the future, with months of transmission lasting up to 12 months in most states. experts warn.
