Chembio Appoints Distributor for its Rapid HIV Tests in Tanzania; Regional Director Establishing Regional Distribution Network to Serve Expected Demand.

MEDFORD, N.Y. -- Chembio Diagnostics, Inc. (OTCBB:CEMI) has appointed Anudha, Ltd. to distribute the company's rapid HIV tests in Tanzania. Anudha Ltd. is a well known distributor in Tanzania that works closely with the Tanzanian government.

Chembio, whose HIV STAT-PAK(TM) Dipstick is part of the national testing protocol in Uganda, established a regional office in Tanzania in June 2005 led by Dr. Jay Drosin. The Company believes there will be a significant scale-up in the demand for rapid HIV tests in Tanzania and other countries in the region which have been ravaged by AIDS. Tanzania is one of fifty countries worldwide that is part of the Clinton HIV/AIDS Initiative Procurement Consortium. Chembio was recently selected by the Clinton HIV/AIDS Initiative ("CHAI") as one of four global suppliers to these countries pursuant to Memoranda of Understanding (MOU) CHAI has with them.

African countries are the largest recipients of international funds for treating AIDS through programs that include the current U.S. President's $15 billion Emergency Plan for AIDS Relief, as well as other multi-lateral programs affiliated with the United Nations such as the UNAIDS '3 by 5' initiative. Combating HIV/AIDS can only be achieved by a massive scale-up of rapid testing.

Chembio's Tanzanian distributor, Anudha Ltd, distributes a full range of hospital and laboratory equipment, diagnostics and reagents along with surgical accessories and consumables. Anudha Ltd. is also a consultant to the Tanzanian Ministry of Health.
