Tennis players will be asked not to hand out used towels and sweatbands to fans as part of further action to try to combat the spread of coronavirus.
The ATP and WTA have jointly announced precautionary measures to be implemented at tournaments including Indian Wells and the Miami Open.
Players will also not accept pens, tennis balls or other items from fans for autograph signing.
The measures will be implemented at all ATP and WTA tournaments during the 2020 spring season with “a further review to follow”.
Indian Wells organisers had previously introduced precautionary measures, with qualifying for the tournament starting on Monday in California.
