Which factor is likely to contribute the least to post-transplant infections?

Hygiene practices significantly reduce the risk of infections in transplant patients. Proper hygiene protocols, such as hand washing, sterile techniques during procedures, and maintaining a clean environment, are fundamental measures in preventing the introduction of pathogens that could lead to infections. High standards of hygiene help protect immunocompromised patients, particularly those on immunosuppressive therapy, which means that good hygiene practices will likely contribute the least to the risk of post-transplant infections compared to other factors like immunosuppressive therapy, which directly weakens the immune system, or medical complications during surgery, which can introduce bacteria or result in wounds that are susceptible to infection. While poor nutrient absorption might play a role in overall health, it is hygiene that acts as a primary defense against the incidence of infections post-transplant.
