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.
Mosquitoes are perhaps the best known invertebrate vector and transmit a wide range of tropical diseases including malaria, dengue fever and yellow fever. Another large group of vectors are flies.
The vector carrying the highest number of diseases is the mosquito, which is responsible for the tropical diseases dengue and malaria. [17] Many different approaches have been taken to treat and prevent these diseases. NIH-funded research has produced genetically modify mosquitoes that are unable to spread diseases such as malaria. [18]
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.
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.
Home to about half a million people, Niteroi has had just 403 suspected cases of dengue so far this year, and its incidence rate per capita is one of the lowest in the state, with 69 confirmed ...
Transmission can also be indirect, via another organism, either a vector (e.g. a mosquito or fly) or an intermediate host (e.g. tapeworm in pigs can be transmitted to humans who ingest improperly cooked pork). Indirect transmission could involve zoonoses or, more typically, larger pathogens like macroparasites with more complex life cycles.
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.
