As a student at the Karolinska institutet, Afzelius studied under the prominent dermatologist Moritz Kaposi (1837–1902) in Vienna. Kaposi has now become a household name because "his" sarcoma is a common lesion in the acquired immunodeficiency syndrome.

In a 1909 meeting of the Swedish Society of Dermatology, Arvid Afzelius presented research about an expanding, ring like lesion he had observed. Afzelius published his work 12 years later and speculated that the rash came from the bite of an Ixodes tick. This rash is the early stage of Borreliosis, now known as Erythema migrans, an early indication of Lyme disease.

Borrelia afzelii, one of the borrelia species that is an agent of Lyme disease, is named in his honor.

gollark: As I said, I think A-level might be better, as I only do 3 (well, 4) subjects I actually like, with better teachers and not with people who don't care, but... well, based on past evidence of school stuff it might also be equally terrible?
gollark: > well, the actual purpose of schools is to teach people things, but most students do not learn anything even if they go to school. source: mean math score being about 4/40 in the university entrance exam.Exactly! It's mostly worthless!
