I am a remodeler and have replaced areas of black mold.it is very bad in many ways and should be removed right away.I had it so bad it almost took my life,but then I was cleaning it all the time,its dangerous tho yes.infection,far as I'm concerned anything that can cause all the rest of what it des may very well be able to cause infection,in fact when I got sick from it antibiotics is the first thing they pumped me with
I Have Black Mold In All My Window Sills And Bathroom, Can It Cause Sinus Infections, Bronchitis, An Ear Infections?
Black mold can cause allergic reactions, respiratory trouble, and a few more things but I am unsure whether it can cause infections.
Debossman is right. There are many illnesses that can come from being around mold. I am allergic to penicillin and when I am around mold I get sick real easy, the sinus, the lungs, and even throw up because of it. I even get a tightness in my chest. So I know it isn't healthy to be around, one thing you might do is scrape the paint off, clean the exposed wood and get something called kilz from Home Depot or Lowes, and paint that on your sills and then let it dry, then paint over it, it should help to prevent the mold from coming back. Hope this helps, good luck to you.
