The<unk> s, like all lymphoid tissue, enlarge when infected. Although lymphoid tissue does act to fight infection, sometimes bacteria and viruses can lodge within it and survive. Chronic infection, either viral or bacterial, can keep the pad of<unk> s enlarged for years, even into adulthood. Some viruses, such as the Epstein–Barr virus, can cause dramatic enlargement of lymphoid tissue. Primary or reactivation infections with Epstein–Barr virus, and certain other bacteria and viruses, can even cause enlargement of the<unk> al pad in an adult whose<unk> s had previously become atrophied.
