Answer:

The correct statement regarding the use of tenofovir vaginal gel by sexually active South African women and its impact on HIV infection rates is: 'Using tenofovir vaginal gel before and after intercourse reduced HIV infection by 39%'. This indicates that the use of tenofovir vaginal gel both before and after intercourse played a significant role in the reduction of HIV infection among this group of women.

It should also be noted that the gel should be used in conjunction with other forms of protection like condoms, to further reduce the risk.
