How is dengue transmitted

According to infectologist Carolina Ponzi, the disease is transmitted exclusively and exclusively through the bite of the Aedes mosquito. Egyptian.

“It also happens that a mosquito feeds on the host’s blood with a virus, becomes infected with the virus and transmits it to another person,” the infectious disease specialist explains.

Ponzi also clears up doubts about transmission and refutes rumors that the disease can be transmitted through other routes such as cough, saliva and air.

According to the expert: “The virus is not transmitted directly from person to person. For transmission, you need a mosquito. The only vector for dengue fever is the Aedes mosquito. Egyptian“.

Dengue can only be infected four times

Only those who have had four varieties of dengue during their lifetime are immune to the disease, as there are only four different serotypes of the virus, Ponzi said.

Serotypes are different strains or types of a particular virus or microorganism. In the context of public health, especially in relation to infectious diseases, serotypes can refer to different strains or subtypes of a particular pathogen.

Each serotype can have unique characteristics, such as different surface proteins, which can affect its ability to infect cells and cause disease.

“Each serotype of the virus, when it infects a person, produces permanent antibodies that prevent re-infection with the same serotype.”

Ponzi then states that: “Because there are only four serotypes of the virus, there is a possibility that there can only be 4 dengue. He who has had it four times does not take any more.”
