###Human: Do 62 % of pregnant women with pityriasis rosea have a miscarriage? ###Assistant: Thank you for giving me opportunity to treat your skin problem. Yes, you are right there are significant chances of miscarriage if Pityriasis Rosea appears in first few weeks of gestation. Mostly miscarriage occurs when Pityriasis Rosea happens after HSV 6 & HSV 7 infection (according to literature). There are also other causes of Pityriasis rosea other than HSV6 & HSV7, Like some drugs (Medicines), Vaccination, other viruses. So, First if possible provide me photographs of affected areas of skin which will help me for better diagnosis and proper plan. Does you had fever or Joints pain few days back? For Viral infection (HSV 6 & 7) you can go for serum Ig M, Nested or RT PCR and viral load, also pregnancy outcomes depends on Body surface area involvement and Constitutional symptoms. Final decision about to continue pregnancy is yours. You also consult with your Obstetrician/ Gynaecologist for the same. Thank you.
