Mobile phone virus infects Helsinki athletics championships

Visitors to the world athletics championships in Finland have had to brave wind and rain, and officials say they now face the possibility of catching the world's first mobile phone virus.

Officials in mobile-mad Finland, home to the world's largest cellphone maker Nokia, said there had been outbreaks of the Cabir virus at Helsinki's Olympic Stadium.

"At most we are speaking about dozens of infections, but during a short period and in one spot this is a huge number," said Jarmo Koski, a security official at telecoms firm TeliaSonera.

Cabir, first reported in June last year, uses Bluetooth short range wireless signals to jump between cellphones.
