The Centre for Health Protection is monitoring 25 Middle East Respiratory Syndrome cases in Saudi Arabia.
The patients include 16 men and nine women aged 16 to 76. Ten of them are associated with an ongoing MERS outbreak in a Riyadh hospital.
To date 1,542 cases have been reported to the World Health Organisation, including at least 544 deaths.
Travel agents organising tours to the Middle East are advised not to arrange camel rides and activities involving the animals which may increase the risk of infection.
