Human Rabies --- Indiana and California, 2006
Just two cases from 2006....note the following from Indiana:
Public health investigation. The patient's mother reported that in mid-June, the girl had awakened her during the night and said that a bird or bat had flown into her bedroom window and bitten her. The mother saw a small mark on the girl's arm, which the mother washed and treated with an over-the-counter first aid treatment. The mother then went to the girl's bedroom to see whether an animal was present. Finding none, she assumed that the incident was a nightmare, not uncommon for the girl. Approximately 2--3 days later, an older sibling took a dead bat away from the family cat; however, the mother did not associate this event with the previous incident and did not seek rabies PEP for the girl. The mother later reported that at the time of the incident, a bedroom window was probably open without a screen in place.
