Dengue virus is transmitted to humans by mosquito bites from infected Aedes species. However, not all mosquitos can transmit the dengue virus. The infections are carried and transmitted by the vector mosquito species to its host organism. Almost half of the population is at risk of contracting dengue fever. Arthropods, such as mosquitoes, are the most prevalent vectors, and they can transport ticks, lice, fleas, and flies. Yellow fever, malaria, and the dengue virus can all be transmitted by these arthropods.
When a mosquito bites a dengue-infected person, the disease is passed through the blood to the mosquito. Through a mosquito bite, this sick mosquito can subsequently spread the illness to all other healthy persons. As a result, dengue fever cannot be passed from one person to another. However, a single infected mosquito bite is all it takes. The Aedes aegypti gene is primarily responsible for the transmission of dengue fever. The white strides on the mosquito’s leg, as well as the silver strides-like pattern on its body, help to identify it. These mosquitoes are more intimately associated with human living places. These mosquitoes spend their entire lives around humans, breeding and laying eggs.
The Dengue Transmission Cycle –
Dengue fever is transferred by a human-to-mosquito-to-human cycle. Dengue fever causes viremia, or high quantities of dengue virus in the blood, which takes four days to develop. These levels might persist anywhere from five to twelve days in an individual. Dengue symptoms usually occur after 5 days and might persist up to a week or longer. It’s critical to diagnose dengue fever early and treat it before it leads permanent damage.
