Undetectable HBV

[Jamjam342]

Is undectatable hep b infectious? The undetectable viral load is 10...getting lots of different answers.

[Kazfiz]

Consultant told my husband if viral load is undetected in blood then he can not transmit the virus to any one at all.

[Jamjam342]

Out of interest what level was your husband’s hbv viral when it was undectable? Mine is 10 ui/ml

[Kazfiz]

To be honest I'm not sure his liver specialist just said undetectable.... He told us no virus in blood = uninfectious..... Obviously DNA can fluctuate so still treat it as being infectious unless hsag has disappeared.... Just I get so paranoid about transmission risks its just a little reassuring to know. He even went as far as saying in this moment in time my husbands blood could be injected into somebody and still wouldn't infect them.
Extreme comment coming from a Dr I thought but we arnt silly people and my husband would never let his guard down whilst carrying the surface antigen. Also told us that saliva is uninfectious too which was another controversial comment

[Jatashankar]

If u r hbsag positive u r infectious in any circumstance. Not related to hbv DNA significantly

I agreed with jatashankar, before my hbsag was negative, I hbv DNA viral was low and sometimes undetected, sometime detected but below 29ui/ml, but machine can not quantify it, my doctor told me my infectious level  is very low.  Now that my hbsag is negative, I have been checking every 6 to 12 months for last 4 years, and hbsag still negative, no longer infectious, even thought I still have remanent of hbv virus live inside my liver cell forever, my immune systems is able to suppress the hbv from circulating in bloodstream.
