ELi5: why can’t we completely get rid of viruses from the body? Ie: HIV, HEV, etc

304 viewsBiologyOther

I understand that viruses can be suppressed by the immune system – but it seems most tend to continue living in our bodies and we only get “sick” from them when our immune systems are weakened.

Why can’t we create a cure that eradicates the virus from the body? Not talking about retroantivirals.

Its kind of possible now with bone marrow transplants.

HIV is a blood virus. Your blood cells are created by stem cells in the bone marrow. You basically nuke the body with radiation and chemo, so that all the stem cells die. Then you transplant donor cells from a matching individual. The stem cells take hold in the marrow and start producing cells with your donors dna. The new cells see your old blood cells as foreign and attack them. This is how some blood cancers are treated
