red nose

[faryan]

I wonder if some one could clear the clouds here. Is 'red nose' an infectious disease itself or would be caused by another kind of disease like the flu or a cold?

There is no disease known as 'red nose'.

NOT A MEDIC

There is a disease that is commonly called red nose disease, namely Rosacea.

* Hello Faryan,


Red Nose is not a disease but, rather, a common moniker for four very real conditions. The causes of “red nose” can be either infectious or non-infectious. Two non-infectious causes are:

• Alcoholism (drinking alcohol often causes a temporary reddening of the nose, especially in fair-skinned people) and
• Systemic Lupus Erythmatosus, an autoimmune disease, which causes skin manifestations in the form of a butterfly-shaped facial rash. (1)

Technically speaking, Rosacea is not an infectious disease but, rather, a chronic, inflammatory skin condition. It causes redness on your face and can also produce small, red, pus-filled bumps or pustules. While these bumps or pustules are small infections, they are the result, not the cause, of the condition. (2)

Erysipelas, is definitely a bacterial infection most often caused by group A streptococcus, and it occurs on the face and neck and cheeks. The bacteria enters through small breaks in the skin and causes a painful, raised, hot, swollen red area of skin that can affect the nose, cheeks and neck. (3)


I'm a retired physician and I hope this helps answer your question.
John
