a lot of infectious disease do not develop symptoms at all .... it depends to one person to another
Good Question!
1. HPV, 2. H.pylori are the only two I can think of. Although there could be more possibly. HPV is Human papilloma virus and can cause cervical cancer and H.pylori is Helicobacter pylori can cause stomach or intestinal ulcers which can turn into cancer as well.
