The incubation stage, the prodormal stage, the illness stage, the decline stage and the convalescence.
1 During this stage of the disease, HIV continues to multiply in the body but at very low levels. 2  People with chronic HIV infection may not have any HIV-related symptoms, but they can still spread HIV to others. 3  Without treatment with HIV medicines, chronic HIV infection usually advances to AIDS in 10 to 12 years. HIV treatment helps people at all stages of the disease, and treatment can slow or prevent progression from one stage to the next. A person can transmit HIV to others during any of these stages: Acute infection: Within 2 to 4 weeks after infection with HIV, you may feel sick with flu-like symptoms. This is called acute retroviral syndrome (ARS) or primary HIV infection, and it’s the body’s natural response to the HIV infection. The Prodromal Period. Once the train leaves the infection station and proceeds through the incubation period, it reaches the next stop or stage of disease development, known as the prodromal period. This is a short stage of disease development where a person begins to feel that they are getting sick. This stage generally lasts about one or two days and is considered to be the time when symptoms show that a disease process is taking place. The acute stage. The disease reaches its highest point of development (severe aches, chills, vomiting, and so on). Recommend on Facebook Tweet ShareCompartir. HIV is a virus spread through body fluids that affects specific cells of the immune system, called CD4 cells, or T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. When this happens, HIV infection leads to AIDS. Stages of Infectious Disease. The above picture shows the stages of infectious disease. Basically, there are five different stages of infectious disease which include the incubation stage, the prodormal stage, the illness stage, the decline stage and the convalescence. Firstly, the incubation period is a period where there are no signs and symptoms detected while the virus is incubating.
