AIDS has the following features 1. AIDS is a retrovirus virus pathogens. Reproductive capacity very soon 2. HIV is not a human organ damage, but the destruction of the body's immune system, thereby causing more organ damage. HIV is growing T4 lymphocyte (T4 lymphocyte cells in the immune system plays a central role in regulating that promotes B cells produce antibodies) and seven nerve cell virus, undermining the body's immune system and damage brain organization. 3. HIV variability very fast, has identified the two types of change : I and Type II, and i-12 parent, reach a six subtypes. 4. Human infections resulting from HIV antibody to the human-antibody protection role, if testing positive for HIV infection for both. 5. AIDS virus in human, very viability not withstand high temperatures, low resistance, leaving human survival difficult, room temperature can only survive a few hours to a few days. Heat-sensitive, in conditions of 56 degrees 30 minutes Inactivatum; For many chemicals, such as 75% alcohol, 2.5% sulfur line, and 0.5% sodium general disinfectants sensitive one minute Inactivatum; Is not sensitive to UV.
Below AIDS has the characteristic
1.AIDS pathogen is one kind counter copies the virus. The reproduction ability is extremely quick
2.AIDS virus is not destroys the human body some organ, but is destroys the human body the immunity system, thus creates the multi- organs the harm. AIDS virus is addicted to the T4 lymphocyte (T4 lymphocyte to play centering control role in cellular immunity system, it can promote the B cell to produce immune body) and is addicted to nerve cell's virus, destroys the human body the immunity system and the destruction brain organization.
3.AIDS virus's variation is extremely quick, at present already found out its two aberrations: I and II, and I has 12 hypotypes, II has 6 hypotypes.
4.After the human body infects the immune body which AIDS virus produces, does not have the immune body protective function to the human body, if examines for the masculine gender already for the infection AIDS virus.
5.AIDS virus outside the human body the survivability range, is not thermostable, resistivity low, leaves the human body not to be easy to survive, under the normal temperature only may live the balance hour to the number day. To hot is sensitive, in 56 conditions next 30 minutes deactivations; To many chemical substances, like 75% ethyl alcohol, 2.5% sulphur tincture, 0.5% sodium hypochlorite and so on the common disinfectant is sensitive, 1 minute deactivation; Is insensitive to the ultraviolet ray.
