When you are first in the heart, battling the virus, you have to double back out the way you came in, because going forward takes you prematurely to the lungs (you have no gravity core). Leave the heart at the upper left and go to the arm, where you will use the coagulator that you have just recovered.
When you have completed the arm and the brain, return to the heart and travel through to the upper right, where you exit to the lungs (the final virus boss).
You go out the way you came.
If you are stuck (cannot click to exit to the stomach), try rebooting Poptropica in your browser. If you are still stuck, try going to Home, then the Store, and get the Haunted House card, which is the only way initially to leave Virus Hunter Island. Several glitches were the result of programming errors that locked up browsers during the first month of the island's appearance.
The 35th island (August 2013) will be Virus Hunter Island.
The game saves by itself.
That is not part of the island quest.
The exit of the hand is at the upper left.
You go to the various organs in order: stomach, hand, mouth (via stomach), intestines, heart, arm, brain, and lungs. Defeating the virus in the lungs ends the quest. (see related solution questions)

You look for a piece of mail with the name Joe Stockholm on it.
He isn't named, so we don't know.
Well since the last island was Virus Hunter island, the next one will be Poptropilis Games 2013.
Select it from the island map. (Paid members only could play 8/29 to 9/12/2013.)
