how it grows
Jul 1, 2003
Does resistant virus grow when it is not in the prescence of drug pressure? If someone is initially infected with a drug resistant virus but has never began anti-aids drugs ..is he infectious to others as far as drug resistant strain is concerned?
Response from Dr. Young
Yes, drug resistant virus can grow in the absence of drug pressure, but the answer really depends on a lot of specifics-- which drugs, which mutations.
So while this statement is not true for all situations, it can definately happen-- moreover, for persons who are infected initially with drug resistant virus (but remain treatment naive), I strongly suspect that transmission of drug resistance can definately occur. Indeed, this is one of my greatest fears in projecting the long-term prognosis for our community-- that is the ongoing transmission of drug resistance. BY
