Leading Veterinary Diagnostic Company Sees No COVID-19 Cases in Pets

Thousands of canine and feline specimens tested surfaced no positive results to date

WESTBROOK,Maine,March 13,2020 --IDEXX Laboratories,Inc. (NASDAQ: IDXX),a global leader in veterinary diagnostics and software,today announced that the company has seen no positive results in pets to date of SARS-CoV-2,the coronavirus strain responsible for the coronavirus disease 2019 (COVID-19) respiratory outbreak in humans. IDEXX evaluated thousands of canine and feline specimens during validation of a new veterinary test system for the COVID-19 virus. The specimens used for test development and validation were obtained from specimens submitted to IDEXX Reference Laboratories for PCR testing.

These new test results align with the current expert understanding that COVID-19 is primarily transmitted person-to-person and supports the recommendation against testing pets for the COVID-19 virus. For dogs or cats presenting with respiratory signs,the recommendation is to contact a veterinarian to test for more common respiratory pathogens.

"Should leading health authorities determine it is clinically relevant to test pets for the COVID-19 virus,IDEXX will be ready to make the IDEXX SARS-CoV-2 (COVID-19) RealPCR™ Test available," said Jay Mazelsky,President and Chief Executive Officer of IDEXX Laboratories. "Pets are important members of our family,and we want to keep them healthy and safe. We will continue to monitor COVID-19 and pet health across our global IDEXX Reference Laboratories network as this situation evolves."
