| Doctors have recently uncovered another worrying development: outbreaks of fungal infections – mainly cryptococcus – that have appeared in previously healthy people. |

| It was the cryptococcus fungus, one of myriad opportunistic infections that can blossom when H. I. V. severely damages the immune system. |
