How Harvey could affect your health
As flood waters recede across Southeast Texas, doctors warn of other potential problems below the surface.
Raw sewage carrying diseases, is likely in much of the floodwater, according to the director of infectious prevention at Christus Hospital St. Elizabeth.
Water collecting and not draining can also become a hotbed for mosquitoes.
In homes, sheet rock and carpets destroyed by flood can grow deadly mold.
Doctors say it's important to wear boots taller than the water and cover any open wounds.
