The outbreak that has infected over 24,000 people and killed nearly 500 in mainland China has forced many stores and factories to close and airlines to cancel flights.
Following in the footsteps of US rival Nike, Adidas announced "the closure of a significant number of our own stores in the country".
Many of its franchises were doing the same, the Bavarian firm added.

Adidas has around 500 of its own stores in China and some 11,500 outlets in franchise stores.
"We can confirm that we are currently experiencing a negative impact on our operations in China," the statement added.
"However, at this point in time it is too early to assess the magnitude of this impact."
Nike on Tuesday also said it expected the worsening outbreak of the virus to have "a material impact" on its Chinese business.
