What are the causes of pityriasis rosea？
Pityriasis rosea is a skin condition, showing as a single, large pink oval-shaped patch on the body. Individuals aged 10-35 are more likely to be affected. It is rare for an individual to infect pityriasis rosesa for a second time.
There are many causes of pityriasis rosea, but the exact causes still remain unknown. Recently, scientists find that a virus from the human herpes called human herpesvirus-6 and/or 7 (HHV-6, HHV-7) has a connection with pityriasis rosea.
Also, the mode of transmission of pityriasis rosea is unknown. According to the research, the virus is not passed by directly contacts with the patients.
Pityriasis rosea can not be noticed easily before the appearance of the rash itself. For a small group of people, it may be accompanied by flu-like symptoms. However, for most healthy people, they don’t exhibit any other symptoms.
If you notice rash on your body, remember to make an appointment with your doctor immediately.
