EBV EBNA strange result

[albertogilardi]

Hello,
hope someone can answer me

I had unprotected sex and after that, in the  next months, i felt very bad...
i had many syntoms especially a very troublesome lymphadenopathy... for almost one year... i was goign crazy!!!
I had all std test negative

My question is about EBV.

After 4,5 months (135 days) from risk exposure (unprotected sex) i had these result:

IgG anti-VCA = Positive
IgM anti-EBV = Negative
EBNA IgG = weakly Positive
EA-D IgG = Negative

I repetead the test after 9 months with these result:

IgG anti-VCA = Positive
IgM anti-EBV = Negative
EBNA IgG = Negative
EA-D IgG = Negative

Why IGg EBNA antibodies passed from weakly Positive (after 4.5 months) to Negative (after 9 months)?
what does it mean? as i know it remains positive all the life....

Is it possible that i contracted EBV virus during my unprotected exposure?

great thanks for your help

yes, what i really cannot understand i why the EBNA igG after 4,5 months were weakly positive and then after 9 months became negative...
it is so strange....

the main symptom was lymphadenopathy... starting after one months from sexual risk... for almost one year
and i had many times in the year flue.... sometimes with fever
also after 5 months from sexual risk i had a strong fever for 10 days... and then i had sore throat for about 3 months...

after first time i tested for EBV i was quite sure about new infection of EBV....
but when i saw EBNA IgG negative after 9 months...

i really dont understand....

hi alberto,

yes it possible to contract EBV through an unprotected exposure.

As you only tested 4.5 months post exposure, your igM will have already become undetectable by then (it is normally only detectable within 2-3 months of exposure). Therefore , your results dont really show if your exposure caused the infection , or if you were infected before.

its difficult to explain how suddenly your EBNA igG became undetectable, because as you said, normally once this is detectable, it remains so for life. I cant explain it, other than maybe the 2nd test was not done correctly,and you should do a re-test to check it .

what kind of symptoms did you have over the 1 year post exposure?
