Welcome to HCM
We understand your concerns
As you have researched and found out, Scabies
is highly contageous through person to person. You are also prone because you did interact with a scabies patient closely including touch. After infection, it might take 4 to 6 weeks for the symptoms to appear. Initial symptoms should be itching and scaling. Don't wait for that long. Consult a general physician and start taking medicines for scabies.
But don't worry, it is fully curable
Get well soon.
