Congratulations on being diagnosed. H.pylori is readily treated with 14 days of rather common (and inexpensive) antibiotics. I know. I was just so cured. But only after enduring a variety of expensive treatments for idiopathic thrombocytopenia purpura a condition that ate my platelets (almost all of them) putting me in danger of bleeding to death internally. H.pylori can also cause ulcers or stomach cancer. I never knew I was infected. Several Hematologists asked if I’d been sick. I said no. I’d had no symptoms. But after 6 months of ineffective treatments, a local hematologist tested for H.pylori because here in south Texas along the Rio Grand it’s common. Sure enough I’d had it and the antibiotics did the trick quickly.
Were I you, I would focus on getting prompt treatment for you and your partner. A fortnight of celibacy while on the antibiotics might be better than worrying about infecting your ever lov’n.
