Galicia is raising awareness about the threat posed by the Vespa velutina, commonly known as the Asian wasp, since it has become the main cause of allergies due to Hymenoptera stings in this Autonomous Community. In fact, a staggering 77% of vaccines administered are specifically aimed at preventing the adverse effects of their bites.

In this article we are going to tell you why they are found Spain on alert due to the risk of being stung by the Asian wasp.

The head of Allergology at the Santiago de Compostela University Clinical Hospital, Carmen Vidal Pan, shared this information with Efe. During the XLVII Congress of the Castilian-Leonese Society of Allergy and Clinical Immunology of Zamora, Vidal Pan gave a presentation on allergy to the Vespa velutina. The data presented revealed that these particular wasps have displaced the presence of common wasps.

Vidal Pan, one of the best doctors in Spain according to Forbes, has issued a warning statement on the prevalence of anaphylaxis caused by a certain species of Asian wasp in Galicia. This larger than average hymenopteran is now considered the main culprit of severe allergic reactions, making it the most common cause of allergies in this region.

As for Hymenoptera, they have replaced common wasps and bees. This is not because they are more aggressive or bite more, but rather because of their larger size and greater venom. As a means of self-defense, all Hymenoptera have the ability to sting, causing quite a stir. Of the approximately 400 patients who receive the allergy vaccine annually in Galicia, A significant 77% opt for a treatment specifically aimed at Vespa velutina.

Additionally, within that particular autonomous region, there is a specific code dedicated to anaphylaxis, similar to the codes established for conditions such as stroke or heart attack. This code includes the administration of adrenaline.

Carmen Vidal explains that for people who have an allergy and itch for a Vespa velutina, The recommended solution is an injection of adrenaline, as it is considered a life-saving treatment. Allergy patients receive training during consultations to ensure they can self-administer the injection when necessary.

Vaccination is an additional option that can help mitigate the impact of the allergic response. In the event of an Asian wasp sting and uncertainty about allergies, it is essential to maintain composure, as not all stings cause a reaction. However, if any negative symptoms arise, it is advisable to contact the emergency services as soon as possible, 112. It is important to prioritize well-being and take the necessary precautions.

According to Vidal Pan, allergists are well aware of the fight against the Asian wasp and it is necessary for the health authorities in Spain to take the necessary measures. Despite the prevalence of Vespa velutina specimens in Galicia, they have currently spread throughout the country, including the Balearic Islands and Andalusia.

During the congress held in Zamora, allergist Carmelo Escudero from the Niño Jesús Hospital in Madrid addressed the use of immunotherapy as a treatment for food allergies, including eggs and peanuts. This treatment consists of administering increasing doses to helping patients develop tolerance to specific foods, as well as addressing Asian hornet allergy.

Confirming the increase in allergies, José Camilo Martínez, an allergist representing the organizing committee and who spoke at the congress, stated that it is projected that one in four people will experience an allergic reaction at some point in their lives. The congress of allergists brought together nearly a hundred experts in the field in Zamora.

Typically, Asian wasps build their nests in the upper branches of trees. However, when these insects become invasive alien species and venture beyond their natural habitat, they can establish their nests in alternative locations, including ground level and various surfaces such as car tires, roofs, and even cracks in walls. .

The dimensions of the Vespa velutina nests are quite impressive, measuring up to 0,8 meters in diameter and 1 meter in height. These nests are built with paper pulp or cellulose and have an internal air chamber. They normally have a spherical shape, although occasionally they can take on a pear-shaped appearance. It should be noted that the nests are constantly guarded by Asian wasps, which show greater aggressiveness whenever they detect any type of danger, whether intentional or not, in the vicinity of a home.

The sting of an Asian wasp

The venom from the Asian wasp sting is lethal only to people who are allergic to insect stings, including wasps, bees and other insects (which make up approximately 3% of the population in Spain). Additionally, the venom can be fatal to elderly people or people with pre-existing medical conditions who experience multiple Asian wasp attacks.

People susceptible to severe reactions may experience anaphylactic shock as a result of the Vespa velutina sting. This shock hinders the proper flow of blood and oxygen to the body's tissues and organs, which can lead to cardiac arrest or even respiratory failure in the event of a wasp attack. The inflammation of the larynx caused by the bite can be fatal, but only in these specific circumstances.

When stung by an Asian wasp, some people may experience prolonged symptoms, including increased swelling, stinging, discomfort and pain, which may be more intense than those caused by other wasps. If you find yourself in this situation, here is what you should do.

As we have mentioned, people who have allergies to wasp and bee stings, as well as those who are elderly or have underlying health problems, would experience the most serious consequences from being stung by the Asian hornet, which could be potentially fatal. In such situations, it is crucial to quickly transport these people to the hospital for immediate medical attention and administration of corticosteroids, since the venom of these wasps can be fatal for them.

I hope that with this information you can learn more about why Spain is on alert for the risk of being stung by the Asian wasp.
