Earlier this year, the increase in cases of microcephaly in Brazil and its alarming relationship with the Zika virus caused a stir in the press and on social networks with great concern that was extended especially in Latin America. Although it's not yet confirmed his relationship with the problems of birth defects of newborns, it is true that the virus transmitted by the Aedes Aegypti mosquito continues to grow. In the last week they have increased to 201 cases of Zika in Mexico, for example. The figures in fact show an increase of 14.3%, according to newspaper El Espectador. Similarly, the Spanish Ministry of Health has confirmed two new cases of Zika virus in pregnant, one in Madrid and one in Galicia, raising to 82 the number of confirmed infections in Spain. The epidemic Zika virus affects more than 33 countries and tens of thousands of people have been infected by the mosquito Aedes aegypti. As the WHO itself warned, the virus grows exponentially and therefore it is important to remember some facts: Transmission: The virus is mainly transmitted through the same insect that transmits dengue, the Aedes aegypti mosquito, an invasive species that is present in many parts of the world. It is a close relative of the Asian tiger mosquito (Aedes albopictus). Symptoms: Most people infected with the Zika virus will not even realize they have the disease because it has no symptoms. When they do exist, they are characterized by red spots on the skin, fever, eye spots and pains in muscles, joints and head. Usually, symptoms disappear naturally after a period that can range from three to seven days. Treatment: Today there is no treatment for the Zika virus and this is one of the most alarming points. There is also no vaccine against the disease. However, the National Institutes of Health in the United States say the Zika virus vaccine will be ready to start its development in late summer, with which, if all goes well in Phase I of the vaccine, may be distributed from 2018. Prevention: Obviously, the best we can do to prevent the spread of Zika is to protect against possible bites of the Aedes aegypti mosquito. It is important to ensure that the form of protection we choose has been proved against this particular mosquito species, such as Radarcan® PORTABLE MOSQUITO REPELLER, with proven effectiveness against Aedes aegypti. Dress with long sleeves and avoid traveling to countries most affected (especially in the case of pregnant women) are other measures also recommended by the authorities to help in the fight against the virus.
