Ringworm infections are most readily spread through skin-on-skin contact. The fungal agents that cause ringworm infections are very adaptable and resilient and can be spread from very brief contact between humans and animals. Ringworm is most easily spread by contact and sweat that are prevalent in many sports.
Wrestling, football, basketball and swimming are the sports most commonly talked about for spreading ringworm infections. The many occurrences during the game where the skin of a player touches another are opportunities for infections to spread if one is present. This is especially true in situations where skin is pressed against skin and sweat is present near a ringworm infection. The sweat works as a conduit and can help the fungal agents transfer from one body to another.
