Can one pus filled pimple(nor itchy nor painful) in ear be herpes? how is it contagious? is ear herpes contagious through kissing? while dormnant?

Unlikely herpes: Herpes usually presents as a cluster of small water filled bubbles surrounded by redness. The fluid becomes yellow and then forms a scab. A solitary area of redness with one single area of pus is more likely to be a pimple related to an infected hair follicle. The fluid in a herpes lesion is contagious and one should avoid contact. A person with recurrent fever blisters can infect others.
