If you think you've been exposed to ringworm, there are some general symptoms to note. Ringworm infections can be itchy and most are red, scaly and cracked, or a combination of all three [source: National Center for Infectious Diseases]. Each specific condition also has its own symptoms.
Tinea corporis is ringworm that occurs in the general body areas - not specific sites like your hands, feet, or head - and will most likely be itchy, scaly and have very clear edges. It's usually red, and often the outside is redder than the middle, which may cause it to look like a ring. This type of ringworm may crack, blister and ooze [source: National Library Medicine].

You may notice a dandruff-like crustiness on the scalp [source: Cleveland Clinic].
