Mold does not cause strep throat. Strep throat is caused by the group A streptococcus bacteria, reports the Mayo Clinic. A highly contagious bacterium, strep is spread by touching a surface colonized with the bacteria and then transferring it to the eyes, mouth or nose as well as through airborne droplets when someone with an active infection sneezes, coughs or shares drinks and food.

While exposure to mold does not cause strep throat, it can cause an allergic reaction in some people that is characterized by coughing, wheezing, a runny nose and irritated eyes and throat, states WebMD. In some people, especially those with compromised immune systems, such as children and the elderly, mold exposure can cause serious respiratory problems, tightness in the chest and breathing difficulty.

While mold allergies most often do not require treatment, strep throat is generally treated with oral antibiotics, states the Mayo Clinic. If left untreated, the strep throat infection can spread to other parts of the body, cause scarlet and rheumatic fever, and cause inflammation of the kidneys.

Mold allergies are best treated by removing the sources of mold in a home, reports WebMD. Fixing leaky plumbing, performing mold testing to identify and remove mold at its source and regularly removing mold from surfaces can help to eliminate allergies caused by mold.
