Is AIDS taking over the world?A disease is an abnormality of an animal or plant, caused by a unhealthful organism. Therefore, disease resistance is the ability to withstand the attack of these pathogens and remain nearly unaffected. The disease may be infectious (communicable), caused by invading organisms that eff parasitically on or within the body. The disease causing organisms entangle viruses, some bacteria and certain other organisms that may be passed from mortal to person e.g. Plasmodium that causes malaria. Other types of communicable disorders are fungal, bacterial and viral diseases. The alternative type of disease to the contagious sorts above, are non-communicable disorders, which are non infectious. These can be caused by unfavourable environ cordial conditions. Cancer, allergies, genetic diseases and mental disorders all fall into this category. AIDS is a viral infection, caused by an ribonucleic acid retrovirus. A virus consists of a strand of nucleic acid (in t his case RNA), wrapped in a capsid (a protein coat). The AIDS virus has an external envelope, do of lipid and protein. This envelope is derived from the cell membrane of the host cell in which the virus replicated. The virus contains reverse transcriptase enzyme. AIDS stands for Acquired Immune wishing Syndrome meaning that oneness is able to catch it, it is a weakness in the bodys system that fights diseases, and is a group of health problems that makes up a disease. A virus called human immunodeficiency virus (Human Immunodeficiency Virus) causes AIDS. If the body is effected, it will adjudicate to fight the infection. The immune system will produce antibodies, which are especial(a) molecules in the blood with the function to attack foreign bacteria or viruses. They attack antigens in a number of ways, by making them ball together, neutralising the toxins released, reacting with the bacterial cells so as to ensure attachment to the phagocytes, and also modify the cell wall using hydrogen peroxide.7 The HIV virus is passed from one person to another via blood-to-blood or sexual contact. In addition, infected with child(predicate) women can pass HIV to their babies during pregnancy or delivery, as hygienic as through breast-feeding. The virus is transmitted in body fluids blood, semen, vaginal fluid, breast milk and other blood containing fluids have all been turn up to carry spread the virus. By killing or impairing cells of the immune system, HIV progressively destroys the bodys ability to fight infections and certain cancers.
