Which of the following is a symptom of mold exposure?

A skin rash can be a symptom of mold exposure as it indicates a potential allergic reaction or irritation caused by mold spores. Mold can trigger various responses in people, particularly those with existing allergies or respiratory conditions. Skin rashes may manifest as hives, eczema, or other dermatological conditions due to exposure to mold, especially in sensitive individuals.

Headaches, metallic taste in the mouth, and weight gain can be related to many other factors and are not specifically indicative of mold exposure. While headaches can occur due to various environmental factors or stress, they do not consistently point to mold as the cause. Similarly, a metallic taste in the mouth is generally linked to other health issues or medications rather than mold exposure. Weight gain, on the other hand, typically relates to dietary or lifestyle changes rather than mold exposure. The connection of skin rashes to mold is more direct, as it is a common symptom experienced by those who are sensitive to molds.
