Parasitologist explains symptoms of subcutaneous worm infection

Mosquitoes can transmit dirofilariasis, a parasitic infection where a thin worm develops under the skin. The parasite, about 10 centimeters long, can be seen moving under the skin, sometimes appearing as a migrating nodule. Cases are increasing in northern regions due to climate change. Symptoms include a visible, mobile lump under the skin. The parasite can migrate to the eye, but is usually removed without lasting damage. Prevention involves insect repellent and deworming pets.
