    Super nice to have some microscopic critter additions!
    As a curiosity, ivermectin the drug used to treat this parasytic infection, is being considered as part of the treatment drugs for Covid-19:

      It's a gnarly illness and I think it's considered to be one of the Neglected Tropical Diseases.

      Have you heard of Loiasis (African Eye Worm)?

The Onchocerciasis

''Onchocerca volvulus'' is a filarial nematode that causes onchocerciasis, and is the second-leading cause of blindness worldwide after trachoma. It is one of the 20 neglected tropical diseases listed by the World Health Organization, with elimination from certain countries expected by 2020.
