About HIV Infection
HIV is the virus that attacks the immune system also called as the body natural defense system by entering into the blood through bodily fluids. This virus will attack the CD4 cells and destroys them, as a result the body defense mechanism will get weaker. This condition gradually destroys the immune system which makes it harder for the body to fight against infections. Person who have infected with HIV may not have any disease symptoms up to 10 years but they can pass the infection to others. HIV infection can be tested by ELISA test and western blot test.
