THE Foreign Office tonight advised against all but essential travel to Mexico after the World Health Organisation upgraded its alert level in the wake of the swine flu outbreak.
A statement posted on the department's website said: "The World Health Organisation (WHO) has raised its Pandemic Threat Alert Phase to Level 4 (evidence of increased human to human transmission).
"We are now advising against all but essential travel to Mexico."
It added: "Routine Consular and all Visa Services at the Embassy in Mexico City have been suspended until further notice.
"British Nationals in Mexico, who have an urgent consular issue should call the Embassy on (01 55) 5242 8500 for assistance.
"British nationals resident in or visiting Mexico may wish to consider whether they should remain in Mexico at this time.
"British Nationals should continue to follow local advice on precautions to take to avoid exposure to the influenza."
Cases of swine influenza have been reported in Mexico City and a number of other locations across the country. Travellers should consult a doctor immediately if they show signs of flu-like symptoms.
