It is in fact possible that he is.  Parasitic dermatozoonosis are skin diseases caused by external parasites that are transmittable from animals to humans. The 3 main ones are flees, cheyletiellosis and sarcoptic mange. Theorically, up to 50% of these infestations can cause symptoms in humans represented by urticarial wheal (small red lesions with itching) caused by insect bites.
They are located mostly around the ankles and lower legs  for the flees, and on the anterior part of the body, the internal part of the arms/ forearms and sometimes even on the face for cheyletiellosis and sarcoptic mange. Do not worry, these parasites are unable to reproduce in humans, making them accidental host or dead-end.

Diagnose on your animal can be made by your veterinarian, although it is important to note that up to 50% of the test results might be negative.  Treatment of the affected animal and all of the other animals in contact with him (because of the important contagiousness) with a topical product for a period of 2 to 3 months, depending on the ectoparasite, will usually result in the resolution of the clinical signs in humans in 1 to 3 weeks.And what about trombiculosis?

Trombiculosis (also known as chigger or harvest mites) is caused by acarids or dust mites.  Only larvaes cause problem, adult forms being harmless.  They are orange and measure 0,5cm.  In the fall, we can find them in gardens and prairies.  They will climb on grass and then will cling on humans or animals where they feed on blood (one meal for 3-4 days.)  Lesions in humans are often mistaken with lesions caused by flees. Small vesicles can sometimes also be seen on the skin.
This is not a zoonosis however, so do not blame your animals!
