The Centre for Health Protection is monitoring five Middle East Respiratory Syndrome cases in Saudi Arabia.
The patients are five men aged 40 to 69. Three had contact with camels, including two who consumed their raw milk. One had contact with a confirmed case.
So far 1,806 MERS cases have been reported to the World Health Organisation, including at least 643 deaths.
Travel agents organising tours to the Middle East are advised to avoid arranging camel rides and activities involving the animals, which can increase the risk of infection.
