Virus! - the most contagious card game. The alarm is raised in the hospital as soon as the laboratory discovers - a little too late - that the virus containers were not as empty as they thought. Your mission is to be the first to stop this outbreak, destroy the viruses and get a healthy body without viruses. Prevent the spread of these terrible viruses.

Try to be the first player to have four healthy organs (without viruses) in your 'body'. A player can discard one to three cards on his turn and add up to three cards to his hand or play one card. When you play a card you may place a healthy organ in your body or place a virus on an organ of another player.

If you place a second virus on the same organ, this organ will be removed. You can also place a medicine on your own organ, to vaccinate against other viruses or to remove a virus that has already been placed. If you place a second medicine on an organ, this organ is immune to other viruses.

Finally, you can play a 'doctor' card. These are special action cards that allow you to steal or exchange organs, spread viruses and discard other players' hand cards.
