Mass HIV test

Acompany said it will help collect saliva samples at a Budapest rock concert next week in what it called the largest mass testing for the HIV virus that has ever taken place, Reuter reports from Seattle. Saliva Diagnostic Systems Inc said it has been asked by a Hungarian health organisation to distribute its Omni- SAL saliva collection at a concert on 26 November in honour of World Aids day on 1 December. At least 1,000 of the devices will be collected and analysed after concert-goers self-administer the saliva test.
