Fifty years ago, dengue was only a public health issue in a few remote tropical areas. The virus has since spread to over 100 countries, making it a global concern. Nowadays, the many tourists vacationing in these regions raise the risk of spreading the disease upon their return home. The presence of the tiger mosquito (Aedes albopictus) in Spain since 2004 has further raised concerns as it can transmit the virus and lead to local outbreaks.
