Tournament organisers of the prestigious Indian Wells tournament have taken measures to deal with the outbreak of the coronavirus.
They've asked ball boys and girls to wear gloves, and not touch the players' towels during the tournament to limit the potential spread of COVID-19.
Ticket-takers, restaurant and food supply workers will also wear gloves.
The Indian Wells tournament takes place in California, where a 71-year-old man has died and more than 33 people have tested positive for the virus.
Player and fan interaction will be limited and 250 hand sanitising stations have also been installed at the stadium, while spectators who have already bought tickets can request a refund.
Sports leagues around the world are taking action with the spread of norovirus.
Sports leagues around Asia have postponed events for two weeks, while all sports in Italy, one of the worst-affected countries, has ordered all major sporting events throughout the country to be played without fans for one month.
Sports governing bodies and broadcasters in the UK will have meetings next week to discuss the staging of events behind closed doors if the coronavirus outbreak worsens.
Main draw action at Indian Wells begins on Thursday (NZ time).
