Dengue, an infectious disease transmitted by the bite of a mosquito, which is endemic in more than 100 countries spread across Africa, the Americas, Southeast Asia, the Eastern Mediterranean and the Western Pacific, could affect more than half of the world's population, according to estimates of the World Health Organization. Health (WHO), due to the increase that has experienced its incidence during the last decades, and to the new outbreaks in countries that were previously free of the disease.
Thus, in 2010 the local transmission of dengue was reported in France and Croatia, in 2012 an outbreak of the disease was detected in the islands of Madeira (Portugal), and imported cases were reported in ten other European countries. And in 2013 cases have already occurred in Florida (USA) and in China, in the province of Yunnan. In Singapore, moreover, they have seen an increase in dengue cases, and there have been new outbreaks in Laos.
One of the main routes of introduction of dengue in North America and Europe, has been the commercialization of used tires and other handicraft products from Asia that contain larvae of the transmitting mosquito
In North America and Europe, one of the main routes of introduction of the mosquito that transmits the disease - in this case the Aedes albopictus-, has been the commercialization of used tires and other handicraft products from Asia that contain larvae of the transmitting insect.
WHO warns that every year there are between 50 and 100 million cases of dengue in the world, and that severe forms of this disease are currently the leading cause of death in children in some Asian and Latin American countries.
This organization also recalls that there is no vaccine or treatment for dengue that is effective when it comes to fighting the virus, and that the therapies available only serve to alleviate the symptoms. Therefore, the only way to stop the transmission of the disease is to establish preventive measures aimed at preventing the mosquito from reproducing and, in addition, avoid its sting using repellents and mosquito nets.
