The head of the World Health Organisation, Dr Margaret Chan, was speaking at a global forum in Mexico, where the virus first took hold.
Dr Chan was keen to promote Mexico as a safe destination, despite it suffering the largest number of fatalities since the outbreak began over two months ago.
Leaders and experts from across the world gathered in Cancun to see what lessons could be learnt so far, but the advice is still the same.
The best way to avoid catching the virus is simple - wash your hands and avoid coughing and sneezing in public.
The World Health Organisation also promised that poor countries in the Americas would receive enough vaccine to fight the swine flu outbreak.
