Are you guys serious? What kind of jokers are ya'll? I'm a former ICU registered nurse...there are some basic rules for any organ transplant recipient such as strict adherence to minimizing risk of infection...minimize activities in large crowds, stores, movies, etc..until they are fully recovered. Wash your hands well and frequently with warm soapy water...it's the number one way to prevent colds, viruses, bacterial infections of all kinds...practice good personal hygiene...caretaker and patient. Depending on the specific organ there are further details...diet, drugs, nutrition, positive healthy lifestyle, spiritual and social support from your faith, family, friends. If I knew more info. May be able to assist more. If in doubt, CALL your health care professional. Signs of problems would include fever, chills, change in appetite, change in activity or energy, any change from the norm should be addressed right away...good luck in your endeavors and God bless compassionate caregivers. Look online to a reputable source, Mayo Clinic website is great.
