On its website, the Foreign Office says of Brazil:
Levels of crime and violence are high, particularly in major cities.
You should be particularly vigilant before and during the festive and Carnival periods. Bank card fraud is common.
It adds that 155,548 British nationals visited Brazil last year.
British travel organisation Abta said today:
We would strongly recommend that fans buy their tickets from official Fifa-appointed agents to avoid disappointment as major sporting events often attract fraudsters.
There is bound to be a lot of demand for hotels and flights so fans should try and book as early as possible to get the best deals.
The Brazilian authorities are doing, and will continue to do, everything they can to ensure the safety of visiting foreign football supporters, with measures such as increased policing levels.
So now England have qualified for the world cup, how do I get tickets?
Fans heading to Brazil for the World Cup should expect unforgettable atmospheres but also heavily inflated prices and long-distance travel.
