Formula 1 teams are reportedly concerned about the risk of staff contracting the mosquito-borne Zika virus in Singapore later this month.
The Sun reports that 150 cases have been recorded in the Asian city state in the last week.
The report says that Mercedes plans to supply staff with long-sleeve tops, while Nico Rosberg has been consulting with doctors about the risks.
He said: "As a family man now, yes, I will be very interested and look into it when the time comes. I have started discussions about it already."
Singapore race organisers told Speed Week: "The wellbeing and safety of visitors and participants at the Marina Bay Circuit is our absolutely priority.
"We are currently working closely with the relevant authorities and are putting all necessary measures in place. Preparations for our race continue as per normal."
The Singapore Grand Prix takes place on September 18.
