Starbucks has temporarily stopped making drinks in customer-provided cups in the US and Canada.
"We are pausing the use of personal cups and 'for here' ware in our stores,"the coffee giant said in a statement.
"We have provided scenario-based procedural information to our store teams on how to report and support anyone that may express they’ve been impacted by the virus, including store closure decision making support," it added.
The company has also modified or postponed large meetings across its offices in North America and restricted all business-related air travel, both domestic and international, until 31 March.
