Tested positive with strep throat for 3 time in last two months.I have sore throat symptoms but nothing else.Am i a carrier? Am I contagious everyday?

Hard to say: We generally reserve the "chronic carrier" label for those who do not get sick with it, although anyone sick with it carries it for a while. You need to investigate whether you are being reinfected by a third party, your old tooth brush, your dog, etc.Some have resistant strep and need 2 stage therapy. Work the specifics out with your doc.

It can be: This condition is caused by the bug: streptococcus, which can be transmitted via salivary contact. It is not supercontagious like those of chicken-pox or measles which are airborn pathogens--meaning that they can stay in the air and infect others. So, if you are given antibiotics already, you should be fine. Just don't smooch for a few days :-) good luck.

Spread by contact: Strep throat spreads by contact with saliva from the infected person. Avoiding sharing of food or beverages and other close contact until the infected person has been treated with antibiotics for at least 24 hours is wise.

Strep throat, when will i no longer be contagious if it's been a week now?

48 hours: You are not contagious after 48 hours from the start of your antibiotics. In rare instances if you have severe tonsillitis, the contagiousness could last a little longer, or if you develop an abcess. However, you need to finish the full course of antibiotics to prevent recurrences and to prevent development of resistant bacteria in your system.

I am a cosmetology master instructor,  I have a student w strep throat  31 yrs old her 3rd time with strep throat, fever.  How long is she contageous?

She may not be.: Recurrent strep infections can mean the patient is colonized with the bacteria in her throat. You may not be at risk...But good hand washing and wearing gloves can be helpful to avoid infection yourself. If you smoke, stop and she could cover her face with a mask while working. Hope that helps.
