Q. Will IgG antibodies take care of the secondary infection in a HSV 1 postive patient?

Hello doctor,

I recently have had tests done after I was with someone that I do not trust after the fact. The only thing I have come up positive for is the common HSV 1. I remember having one outbreak when I was young and no outbreaks after. I have IgG antibodies present in my blood. I fear that the person I was with carried HSV 1 and reinfected me. I hope that my antibodies reacted and destroyed the second infection.

I had a blister present on my skin after being with this friend. But it healed up immediately, more than a regular blister. Is there a chance that my IgG antibodies took care of the second infection? I told this person that I had perfect sexual health, and it was essential to me and the love of my life, which I am hoping to find. So it has hurt me at a phenomenal rate. I think of it daily.

I need to know if I had IgG antibodies built up before reinfection, can it destroy the reinfection if symptoms are present? My symptom was present one day before it started healing. On the upside, a doctor that looked at it said it was nothing. Other doctors said it was probably nothing. It has cost thousands of dollars to find an answer.

I am looking for a true love to live life out with and this is very important to me. Please let me know if IgG antibodies could kill reinfection if a symptom were only present for a day. It has been about nine months, and I have not had any symptoms. If you can help me, it would mean the universe to me.

Welcome to icliniq.com.

I understand your concern. Please follow the following facts.

1. Once you get infected with HSV-1 (herpes simplex virus), as you had been in childhood, IgG antibodies remain there in the blood indefinitely or life long.

2. They help in containing further episodes, so subsequent episodes of herpes are always less in severity than the primary one.

3. Usually, herpes secondary episodes last for a few days, can heal in a couple of days also if it is minimal.

4. You are getting worried too much, and please relax, it has been nine months, there is no need to panic now.

5. You did not mention the site of blisters or any photographs you have taken, and it might not even be herpes.

6. There is no sign of HSV IgG in blood, and it just indicates you had an infection anywhere in the past.
