The recent expansion of the screwworm in various regions has all alarms have been triggered between pet owners and animal health services. Although livestock are the primary target of this pest, the most recent data indicate that our canine companions are suffering the consequences of this parasite very directly, making it necessary to take extra precautions even in urban environments where it was not previously considered a major risk.
In the latest official counts of affected areas, dogs represent the second species with the highest infection rateThis has resulted in hundreds of active cases requiring immediate medical intervention. This situation highlights how any neglect in the care of a small wound or scratch can lead to serious health complications for pets, especially in warm, humid climates where the responsible fly can reproduce more easily.
What exactly is the screwworm and how does it work?
It is crucial to understand that this problem has nothing to do with common intestinal parasites, but rather with... larva of a specific fly It lays its eggs in open wounds, mucous membranes, or even damp skin. Once they hatch, these worms begin feeding on the animal's living flesh, burrowing deeper and deeper into the body, which distinguishes this species from other larvae that only consume dead tissue.
Once the eggs settle, the infestation can progress with astonishing speed. causing progressive destruction The myiasis, caused by this insect, can affect tissues, including muscles, cavities, and even bones if not treated promptly. It is not only extremely painful for the dog, but it also creates a necrotic environment that attracts more flies, worsening the clinical picture in just a few days.

It is common for the animal to exhibit persistent licking or scratching in a specific area, as well as purulent secretions that indicate something is wrong beneath the skin's surface.
Veterinary specialists usually classify cases according to their severity, focusing on the number of larvae and depth of the lesions found. A mild level may present fewer than ten maggots in a superficial wound, while critical cases show intense lethargy, high fever and a total loss of appetite, putting the dog's life at real risk if it is not taken to the emergency room that same day.
Veterinary protocols and necessary treatments
When a positive case is confirmed in the clinic, the standard procedure begins with thorough cleaning of the area and the use of specific topical larvicides To neutralize the parasites, the veterinarian must carefully remove the larvae and disinfect the cavity with antiseptic solutions, ensuring that no residue remains that could restart the infection or cause generalized sepsis in the animal's body.
In more complex situations where the infection has progressed, it is necessary to administer pain management drugs y systemic antibiotics to fight bacteria Opportunists who take advantage of the wound. Home follow-up after the procedure is equally crucial, requiring daily wound care, the use of an Elizabethan collar to prevent self-injury, and strict monitoring of body temperature during the first few days of recovery.

These flies are very opportunistic and can lay their eggs in places that go unnoticed at first glance, so a careful visual inspection can make all the difference.
Context of the current situation and risks
Although the most worrying hotspots are currently located in regions such as Central America and Mexico, where there are more than two thousand active cases The ease of animal movement and climate change are forcing health authorities in other territories, including Spain and the rest of Europe, to remain vigilant. Epidemiological surveillance and the use of sterile flies They are key to preventing these types of pests from crossing borders and establishing themselves in new areas where livestock and pets would be completely unprotected.
