Graft vs Host disease is reaction to a bone or stem cell transplant. This is when the body rejects the new bone or cells. This can result in system failure and lead to death in extreme cases.
If a host has been infected with a pathogen then theoretically they are a carrier as the infection could spread to others
Leaf wheat rust, caused by Puccinia triticina, is the most common rust disease of wheat. Wind rust spore are blown in the wind and can infect host plants hundreds of kilometers from their source plant, which can result in wheat leaf rust epidemics on a continental scale. It is sometimes called cereal rust because it affects cereal crops.

Blood transfusion graft-vs.-host disease affects mostly the blood.
What does the term "Graft versus host disease" mean? Immunologic reaction involving the attack of host cells by donor immune cells.
The only transplanted tissues that house enough immune cells to cause graft vs. host disease are the blood and the bone marrow.
Graft-versus-host-disease
Bone marrow graft-vs.-host disease comes in an acute and a chronic form. The acute form appears within two months of the transplant; the chronic form usually appears within three months.
A Graft versus host disease is most likely to occur or happen, when a tissue transplant does not take because the body fights the transplanted tissue. The recipient or host body rejects the tissue and attacks it.
The tissues most affected by bone marrow graft-vs.-host disease are the skin, the liver, and the intestines. One form or the other occurs in close to half of the patients
graft-versus-host disease and finding out her cancer had returned.
A graft versus host reaction is a product of stem cells being used to treat disease and not taking to each other. Even when identical siblings have contributed, this complication can happen.

For recipients of blood transfusions who are especially likely to have graft-vs.-host reactions, the red blood cells can safely be irradiated (using x rays) to kill all the immune cells.
A pathogen or infectious agent is a biological agent that causes disease or illness to its host.
