and the disease also reaches the USA

L’dengue infection risks getting out of control Brazilwhere the Ministry of Health estimates that the virus responsible for the disease may strike over the next few months 4.2 million people. This is an alarming figure, if we consider that in 2023 there were 4.1 million infections in all the nations of the New Continent.

Dengue fever in Brazil

Brazil pays for chronic health deficiencies at all levels, from prevention to assistance.
Dengue is transmitted by Aedes Aegypti mosquitoalso a carrier of zika and chikungunya.
The historical series resulting from the observation of the spread of the mosquito demonstrate how the insect has now invaded almost all of South America, moving towards the north. Today there is fear that Aedes Aegypti could also invade USA starting from Puerto Rico. The New York Times has dedicated a service to the emergency, from which it is clear that the areas currently exposed to the greatest risks are “especially in Florida, Texas, Arizona And California southern”.

The climate trend in Brazil has facilitated the spread of the mosquito: the atmospheric phenomenon known as “el Niño” it brought, among other things, a repeated alternation between heat waves and downpours. Practically the ideal climate for the proliferation of the larvae of these insects which have found a home in puddles, manholes, sewers, artificial reservoirs and landfills. In January too Argentina, Chile, Paraguay And Uruguay have seen a surge in infections.

What is dengue fever

As reported by theHigher Institute of Health, dengue is a disease of viral origin caused by four very similar viruses: Den-1, Den-2, Den-3 and Den-4. The infection is transmitted by mosquito bites which, in turn, bite infected people. The main vector is the mosquito Aedes aegyptibut also the Aedes albopictus is capable of transmitting the disease.
Dengue has been known for decades, but its spread is increasing exponentially in recent years due to climate change and the massive movement of people and goods. Dengue, together with West Nile and avian flu, is part of the group of climate viruses that represent a new challenge for humanity.

Dengue has also arrived in Italy, although fortunately at the moment we cannot speak of an emergency.

Dengue: symptoms and therapy

The disease gives rise to fever in the span of 5-6 days from the sting, even with very high temperatures. The fever can also be accompanied by strong ones heachache, eye pain, muscle and joint pain, nausea And vomit And irritations of the skin. Children sometimes lack typical symptoms. Hemorrhagic fevers and collapses are rare. And the disease is rarely fatal.

There prevention is typical of all diseases transmitted by mosquitoes: adequate clothing, specific repellents, mosquito nets and recurrent disinfestations.

There isn’t one treatment specific for dengue: in most cases people recover completely in two weeks. The treatment for dengue consists of absolute rest, constant hydration and the use of drugs to reduce fever.

Dengue vaccine

The World Health Organization is evaluating the development of two vaccines against dengue. The director general of the organization, Tedros Adhanom, said this during a meeting with President Luiz Inacio Lula da Silva and the Minister of Health, Nisia Trindade: “The country could soon be a supplier of the vaccine against the disease thanks to studies by the Oswaldo Cruz Foundation of Rio de Janeiro, linked to the Ministry of Health, and the Butantan Institute of Sao Paulo, linked to the government of the state of Paulista”.
