There are a large number of asymptomatic chronic infections, mostly viral, that provoke immune responses examples are cytomegalo virus evolution of the human immune system the immune system has been primarily moulded by evolution to respond efficiently to acute infections in young. Natural barriers and the immune system defend the body against organisms that can cause infection natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid also, the normal flow of urine washes out microorganisms that enter the urinary tract the immune system.

The human immune system is pretty great whenever a new threat, such as bacterial or viral infection, is detected the cells of the immune system undergo a series of selective divisions, making new cells which are better able to identify the threat, and then initiate the immune response following. Human leukocyte antigens lymph nodes can also swell after an infection because immune responses to infections are generated in lymph nodes the immune system can make this distinction because all cells have identification molecules on their surface. The human immune system is under great pathogen-mediated selective pressure a combination of divergent infectious disease pathogenesis across human populations, and the overrepresentation of immune genes in genomic regions with signatures of positive selection suggests that pathogens have.
To explore viruses/infectious diseases, how they can infect the human body, compromise the immune system, and interfere with normal human body functions in middle school, students should examine the nature, causes, structure, and the basis of infectious diseases, including viruses this lesson.
