The researchers found that the mosquitoes that carry dengue — called Aedes aegypti — transmit the virus most efficiently when temperatures are between 68 and 82 degrees Fahrenheit.
Aedes aegypti (UK: / ˈ iː d iː z /; US: / eɪ d z / or / ˈ eɪ d iː z / from Greek αηδής 'hateful' and / eɪ ˈ dʒ ɪ p t i / from Latin, meaning 'of Egypt'), the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents.
Dengue can be fatal. [52] [53] Dengue fever is spread by the bite of the female mosquito known as Aedes aegypti. The female mosquito is a highly effective vector of this disease. [54] The evidence for the spread of dengue fever is that climate change is altering the geographic range and seasonality of the mosquito that can carry dengue.
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat (ectothermic).
Dengue can be caused by dengue virus strains 1, 2, 3 or 4, with a person being infected multiple times over the course of their life, Duszynski told ABC News, so a vaccine may be able to help ...
Mosquitoes are hatching earlier in Argentina and reaching cooler regions than before, as rising temperatures drive the country's worst outbreak of dengue fever and raise the risk of more regular ...
Over the last twenty years, there has been a geographic spread of the disease. Dengue incidence rates have risen sharply within urban areas which have recently become endemic hot spots for the disease. [57] The recent spread of Dengue can also be attributed to rapid population growth, increased coagulation in urban areas, and global travel.
The mosquitoes Enriquez unleashed in his El Manchen neighborhood — an area rife with dengue — were bred by scientists to carry bacteria called Wolbachia that interrupt transmission of the disease.
