Chembio Appoints Distributor for Its Rapid HIV Tests in Ethiopia.

MEDFORD, N.Y. -- Chembio Diagnostics, Inc. (OTCBB: CEMI) has appointed Setema, Ltd. to distribute its rapid HIV tests in Ethiopia. Ethiopia has a population of over 73 million of which an estimated 1.5 million are infected with HIV. Under the auspices of the President's $15 billion Emergency Plan for AIDS Relief (PEPFAR) and the Global Fund to Fight AIDS, TB and Malaria, the United States recently signed an agreement to provide Ethiopia with over $84 million to prevent and treat HIV/AIDS. This will include a significant scale-up of rapid testing programs. Chembio believes these programs are crucial in Ethiopia and other countries ravaged by the AIDS epidemic. Rapid tests effectively identify patients that may require anti-retroviral treatment. Ethiopia is currently evaluating rapid HIV tests including Chembio's two HIV 1/2 STAT-PAK(TM) tests for possible inclusion in Ethiopia's testing protocol.

Setema is one of the largest medical device distributors in Ethiopia and the country's sole supplier of HIV viral load tests. Viral load tests monitor patients already identified with HIV (e.g., with a rapid test) to determine if and when they require anti-retroviral therapy.

Ethiopia is one of 50 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 of rapid HIV tests to these countries pursuant to the Memoranda of Understanding (MOU) CHAI has with them.
