Chronic chlamydia infection spreads to host cells throughout the body; and as a greater number of cells become infected, a greater number of cells are deprived of the energy and oxygen necessary for cell function, and endothelial damage becomes more widespread. Chlamydia pneumonia can also spread through smooth muscles, and chlamydia DNA has been found in muscles and joints. Chlamydia pathogens infect immune cells attempting to fight the pathogen, causing damage to immune function. When the patient has more than one immortal infection, multiple chronic infections can accelerate the development of chronic disease.
Virtually all chronic diseases include symptoms of chronic fatigue, pain, and reduced immunity. Immortal pathogens attack according to affinity for particular host cells and opportunity. Chronic infection eventually causes widespread damage to the cells, causing fatigue at the cellular level, muscle pain, and chronic diseases. Chronic fatigue, fibromyalgia and autoimmune diseases are symptoms of one or more underlying chronic infections, persisting over a long period of time.
