To the Editor:

The papers of Gormus, et al. (3) and Baskin, et al. (1) suggest that SIV infection increases the risk for the development of leprosy in experimentally inoculated rhesus monkeys, although their results were not statistically significant (3/5 SIV-infected and 6/29 non-SIV-infected monkeys developed leprosy; Fisher's exact test p > 0.05). The papers by Ponnighaus, et al. (4) and Borgdorff, et al. (2), on the other hand, aimed at estimating the risk of HIV-1 infection for the development of leprosy in humans.

Once cannot simply extrapolate statements on SIV in rhesus monkeys to those on HIV-1 in humans. However, if both SIV in rhesus monkeys and HIV-1 in humans increase the risk for developing leprosy (as some, although not all, of the evidence suggests), the former may be a good model for the latter.
