Surely, if anyone asks you what animal or insect is the most dangerous in the world, you won't thik of a mosquito. However, mosquitoes are the deadliest animal on the planet and cause millions of deaths each year due to disease transmission.
The Aedes aegypti mosquito, also called yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunay and Zika, among other diseases. To recognize it, we can look at their distinctive white markings, although their differences from other mosquitoes can be difficult to find.
Aedes aegypti is a subgenus within the genus Aedes, native to Africa and today is found in tropical and subtropical regions throughout the world. Shares habitat with the Aedes albopicuts (also vector of dengue).
According to WHO, it is estimated that this mosquito species cause 50 million infections and 25,000 deaths annually.
The Aedes aegypti can feed at any time, but usually bite most often at dawn and dusk. The places where they can reproduce with better conditions have stagnant and cean water.
Like all insects, the life cycle of Aedes aegypti is accelerated between 25 and 27 Celsius degrees, until it dies above 40.
How they transmit the virus?
If the mosquito bites an infected person with Zika, dengue or any other diseases, he contracts the virus from the infected person. The virus takes five to seven days to be played on the infected mosquito. During this time, the virus goes to the salivary glands of the mosquito.
Of these glands, the mosquito spread the virus from their saliva to the person who bites, creating a potentially new infected person. A single infected mosquito is able to infect several people.
