level 9
Most people infected with HIV do not know that they have become infected. HIV infected persons develop antibodies to HIV antigens usually 6 weeks to 3 months after being infected. In some individuals, the test for the presence of these antigens may not be positive until 6 months or longer (although this would be considered unusual). This time -- during which people can be highly infectious and yet unaware of their condition -- is known as the "the window period".
6周-3个月才是最正统的!!!
