Major tech companies are skipping the inescapable Mobile World Congress this year owing to fears over the coronavirus, though Chinese groups including ZTE and Huawei still plan to attend.
Amazon and Sony said Monday they will steer clear of the world's biggest mobile tech fair in Barcelona, joining Swedish telecoms equipment maker Ericsson and South Korean giant LG.
The annual gathering is to take place on February 24-27 this year.
"Due to the outbreak and continued concerns about novel coronavirus, Amazon will withdraw from exhibiting and participating in Mobile World Congress 2020," a Spanish-language statement said.
A Sony statement said: "As we place the utmost importance on the safety and wellbeing of our customers, partners, media and employees, we have taken the difficult decision to withdraw from exhibiting and participating at MWC 2020 in Barcelona."
LG, which normally has one of the biggest stands, said last week that its decision "removes the risk of exposing hundreds of LG employees to international travel which has already become more restrictive as the virus continues to spread across borders."
