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.
In a joint statement, the ATP and WTA said health and safety is "paramount".
"As the outbreak of COVID-19 continues, these are common sense precautions for us to take," the statement added.
