Is Loa loa harmful?
Loa loa is only mildly pathogenic. Adult worms wander throughout the body, moving through the tissues at a maximum rate of about 1.5 cm/minute. The most troublesome infection sites are the conjunctiva (Fig. 17-5) and the bridge of the nose, where impaired vision, irritation, and pain may result.
Is Loa loa blood parasite?

This is generally benign and should not be confused with the inflammatory response to intraocular microfilariae that leads to blindness in onchocerciasis.
