AIDS and HIV : causes, symptoms, AIDS transmission
AIDS and HIV:-
acquired immune deficiency syndrome, (AIDS) is the disease caused by HIV, human immune virus resulting in destruction of human immune system. AIDS is manifested by the group of symptoms with different infections. As the immune system becomes weak an individual is prone to get any infection easily, and the worsening of disease symptoms leads to death of an individual affected with AIDS.
AIDS leads to chronic or gradual deterioration of human immune system and destroys CD4 Positive T cells there by reduces the body resistance to infections diseases. HIV infected person or AIDS person gets an endless infection and chronically becomes ill.
It is highly difficult to understand the replication and division of Human Immune Virus, so no effective Vaccine against AIDS have been established.
The main channel of transmission of AIDS or HIV is through direct contact to:-
* Mucus membrane,
* Body fluids such as blood etc..
An estimation in 2007 shows that nearly 33.2 million people lived with AIDS worldwide and 2 millions were killed by AIDS , including thousands of children.
Even though the treatment are available for AIDS / HIV infection, no permanent cure, no effective vaccines established.
HIV is a retrovirus, replicated inside the body using DNA genes.
Causes of AIDS / HIV infection:-
AIDS is a immune deficiency disorder caused by HIV. The human body has white blood cells, and lymphatic system which provides immunity to body and provides resistance by fighting against disease causing agents. The HIV virus after entering body, establishes infection and starts destroying the T lymphocytes in the human body, ESPECIALLY THE cd4 POSITIVE LYMPHOCYTES. This weakens the immune power and reduces resistance of body to diseases.
Transmission of AIDS / HIV:-
Sexual transmission : Is the main channel of AIDS / HIV transmission. During oral sex, or active sex, the HIV is transmitted through body fluids and contact with mucus membrane and mucus produced during sex. Sharing uncleaned sexual devices which are not covered by condom also may transmit the HIV infection.
KEEP in the mind that SEX WITH HIV INFECTED PERSONS ONLY TRANSMITS THE AIDS / HIV INFECTION, NOT AN UNPROTECTED SEX WITH normal individual. Except condom use, any other protective sex using chemicals also may cause AIDS/ HIV infection.
Transmission through infected Blood : Contact of body membranes or body fluid with HIV infected blood causes AIDS/ HIV infection. Infected syringes, untested infected blood transmission, using infected razors and blades for shave, medical persons who come in contact with infected blood or infected materials such as instruments accidentally are at risk of getting AIDS/ HIV infection.
Transmission through needles : Infected needles transmits the HIV virus and causes AIDS. Special care by medical persons not using infected needles and instruments helps in preventing AIDS.
Transmission through mother to fetus or baby : Thousands of infants or babies are infected with AIDS or HIV from the infected mother. The HIV virus is transmitted through placenta in the womb itself, and the baby in the womb get affected with AIDS /HIV. Now a days is possible to prevent transmission of AIDS from mother to baby in the womb. The transmission of AIDS through mother to baby is high in poor countries.
ARE the main causes and transmission channels of AIDS / HIV.
