I need an answer...?

Question

people who have detectable antibodies for hiv-1 is 45 days . does this apply to hiv-2 ? This is a serious answer, as i cannot find it anywhere...

Answer 1

Hello,

Thanks for the great question. Well hiv-1 and hiv-2, share the same mode of transmission and also opportunist infections.

Below, is some information which should give you an insight unto how hiv-2 and hiv-1 operates in terms of detectable antibodies.

The risk for HIV transmission by transfusion of screened blood is minimal. Nearly all cases of transfusion-associated HIV transmission are now caused by blood donated during the infectious window period (i.e., when recently infected donors are infectious but have not yet developed detectable levels of HIV antibody). When whole-virus–lysate enzyme immunosorbent assays (EIAs) were used to screen blood donations from 1985 through 1990, the average length of the window period was 45 days (95% confidence interval [CI]=34–55 days) (3). The average window period of the most sensitive contemporary recombinant protein-based EIA for HIV-1 and HIV-2 antibodies is now 20 days less (4), yielding an average infectious window period of 25 days (95% CI=9–41 days) (5).
