There are more and more cases of Dengue fever in Italy, but what catches the eye are those transmitted locally.
What does it mean? They are called "native cases" and indicate transmission which occurred directly in our territory.
Dengue fever, as well as other tropical diseases, should arrive in Italy and not be favored by our climate.
Unfortunately, the climate crisis leads to an increase in temperatures and their tropicalization (wetter environments).
It is no coincidence that we also speak of the "globalization of diseases".
However, there is no need to be alarmed, explains Marino Faccini, director of the Department of Hygiene and Health Prevention of the ATS Milan Metropolitan City.
In fact, the people affected by Dengue fever have all recovered or are improving.
However, this does not mean pretending that there is no greater risk of contagion in Italian environments, so much so that the expert always invites us to be aware that we have a tropical infection at home and that we need to protect ourselves in situations where there is a risk of a bite or cause an outbreak to develop.

How to defend yourself? What does it mean that the cases are indigenous? The tiger mosquito is in a favorable environment, that is, the "tail" of the summer heat that has crept into autumn.
In some Italian regions, more than others, this favors the active circulation of the mosquito and therefore also of indigenous cases of Dengue fever.
Emanuele Nicastri, director of the Division of high-intensity infectious diseases of the Lazzaro Spallanzani National Institute for Infectious Diseases in Rome, explains the reasons.
Today one in three of Italian cases of Dengue is indigenous and comes from the regions involved (Lazio and Lombardy).
Regarding the future of circulation, it is good to know that Dengue cases will end when the circulation period of the tiger mosquito ends.
“We can hypothesize that this will happen, if temperatures drop, in the first weeks of November.
However, this is an estimate, because everything depends on the climate,” explained Nicastri.
The disease is not worrying and the contagion window should soon close again.
It is also true that the summer season has now extended to May and continues until September-October, increasing the possibility of contagion from similar viruses.
How does contagion happen? Dengue fever is a viral disease that can be caused by four different viruses, each of which is transmitted via a tiger mosquito.
For contagion it is therefore necessary for a mosquito to bite a person and for transmission the intermediate passage of a vector is always needed.
The way Dengue spreads therefore does not represent a serious risk, at least for Italians.
Even if the indigenous cases indicate, without alarmism, that we need to start taking into consideration the risk of contagion.

The disease, which results in a fever lasting 5-6 days from the moment of the mosquito bite, reaches very high temperatures.
Fever is accompanied by a number of other symptoms, such as: headache pain around and behind the eyes muscle and joint pain nausea and vomiting skin irritation There is currently no specific treatment for Dengue.
In fact, as Epicentro writes, in most cases people recover completely in two weeks.
However, supportive care such as absolute rest and medications to reduce fever can be applied.
Attention: there are also more serious cases, such as when it presents in a haemorrhagic form, the procedure is followed in hospital to avoid collapse and, in rare cases, death.

The most effective prevention is to avoid mosquito bites.
To prevent Dengue fever, some precautions were needed against the insect vectors of the virus.
Tips for preventing mosquito bites include: wearing light-colored clothing that covers most of the body; night-time protection from mosquitoes, such as a mosquito net around the bed; use of skin repellents; use of insecticides in homes; install mosquito nets on doors and windows; avoid outdoor activities in the late afternoon.
