We live in an old trailer the roof has leek off and on over the past few years there is no visible Signs of mold but I'm certain it's there in places that can not be reached to clean. Inside vents walls ect. My 6,yr old son keeps getting an infection that at first tested positive for strepthroat the first 3 times it was treated with antibiotics 2 weeks after finishing the antibiotic my boy was sick again the last time I was told it's not strep it was just a virus that had to run its course with out medcian it did he was fine no symptoms.about 3 weeks later he is sick again with all the symptoms streap throat comes with. Could it be mold of something else in the trailer I'm overlooking my son has been sick 5,times since May in put of any kind will be most appreciated thank you. Sherry and Lewis
