Bats infected with rabies have attacked more than 500 indigenous people in Peru's Amazon and four children are likely to have died in an outbreak of the disease.
The attacks occurred in the village of Urakusa, in north-eastern Peru, where the Aguajun tribe lives. Jose Bustamente, a health ministry official, said medical supplies had been sent to the tribe.
Rabies is usually spread to humans by dog bites. Health teams are looking for people within six miles of the outbreak who were attacked by bats in the past six months.
