In the last week it has been confirmed that two Spanish citizens belonging to the same family have contracted dengue in Spain . This has been confirmed by the Ministry of Health. Both patients are well, and there is the possibility that there is a third case since there is a third person who has symptoms and is pending confirmation.
During the period in which they could have contracted the infection, the three people were in various municipalities in the provinces of Murcia and Cádiz . They are two autochthonous cases of dengue, of residents in Spain and who have not recently traveled to endemic countries.
The health authorities have explained that the infection has occurred in two ways. The first one, due to the arrival in Spain of a mosquito carrying the virus. And the second, that the mosquito in Spain has bitten a person carrying the dengue virus and subsequently infected people.
Tiger mosquito, responsible for the transmission of the dengue virus
As indicated by the Spanish health authorities based on the data that are known so far, the only competent vector to transmit the dengue virus is the tiger mosquito , which is widely spread on the Mediterranean coast.
This mosquito arrived in Spain in 2004, and since then it has significantly expanded its population. There is a history of the yellow fever mosquito , which today does not have a presence in Spain, but it did have it in the past and was introduced by ships returning from the Americas. Thus, in the 18th century there were several yellow fever epidemics , which claimed the lives of hundreds of thousands of people.
Dengue is a disease of viral origin that is transmitted through the bite of mosquitoes infected with the virus ; in no case does the contagion occur from person to person. In Spain, the only competent vector for the transmission of this virus is the tiger mosquito. It is a diurnal and highly invasive species.
In the vast majority of cases, dengue is a disease that gives rise to symptoms very similar to those of the flu : muscle pain, fever and headache . As the disorder progresses, other signs appear, such as swollen glands and a skin rash. Only in certain cases does dengue evolve into more serious situations, in which blood coagulation is altered, leading to bleeding and organ failure.
