A Serodiscordant (sero-discordant) or magnetic relationship is one in which one partner is HIV positive and the other is HIV negative. This contrasts with seroconcordant relationships in which both partners are of the same HIV status (i.e. both are HIV positive or both are HIV negative).
Serodiscordant couples face numerous issues not faced by seroconcordant couples, including facing a decision as to what level of sexual activity is comfortable for them, knowing that practicing safer sex reduces but does not eliminate the risk of transmission to the HIV negative partner. There are also potential psychological issues arising out of taking care of a sick partner, and survivor guilt. Financial strains may also be more accentuated as one partner becomes ill and potentially less able or unable to work.
Research involving serodiscordant couples has offered insights into how the virus is passed and how individuals who are HIV positive may be able to reduce the risk of passing the virus to their partner.
Here are some of the most recent information and resources regarding sero-discordant coupling.
