To not get the virus.
1. Chose a certain amount of players to be IT. There has to be an appropriate ratio of IT’s to players (e.g. 5 ITS: 25 Players)
2. The ITS will have a special infectious “virus” on their hands. If they tag another player on the arm, the virus has now transferred to the other player. Now the other player has become infected on their arm and their goal is to get rid of their virus by tapping someone else with their arm.
3. Basically, wherever the IT person tags someone, they have to tag the next person by the part that they were infected.
