PCR swab

Born to worry

Hi Guys

can anyone advise on my question regarding a PCR swab

When you swab a sore/blister and if the virus is on the swab, can the virus die and not be able to be detected after a period of time ?

I always thought that a virus wasnt alive so therefore it wouldnt be a problem ??

If its always going to be there an detectable can you keep the swab stick for a while and swab any blisters or sores that appear over lets say 2 weeks ?

I appreciate any answers

From what I have read (I'm not a doctor) the virus needs to be "alive" ie an active blister/sore to be swabbed to get the best chance of giving an accurate result. The sample is put into a special container and sent off to the lab asap. The bigger the blister the more active virus is present and therefore is more available for testing.

Thanks for the reply !

ok so lets say the virus has been collected on the swab from a active blister, ive looked around on the net and it seems to be that a virus isnt actually a living cell, so with that in mind, if the swab was left for two weeks in its container, would you still get a positive result when it gets to the lab???

      I'm not that well versed in HPV but HPV eventually is cleared by the body on its own.  A vaccine does exist which helps immunize against certain strains of HPV (not all of them), but will not treat HPV for those who already have it.  Everyone, male and female, who is eligible should get the Gardasil vaccine. If a new vaccine exists to treat HPV that's great, but I'm doubtful based on a quick Google search.

      I am new to all of this. My girlfriend has been told by a docter she has Human Papillomavirus (HP) and that in Mexico they have a cure they just develop, I guess a month or so ago Human Papillomavirus (HPV) vaccine , have anyone heard of this. It is a lot on the internet about it. But I don't know how much I trust it.. Thank you AMM
