Five new cases of swine flu were discovered in Lebanon on Tuesday but were under control, the health ministry said, bringing the total number of cases there to eight.
"The cases were isolated and treated and preventive measures were taken for all those they came into contact with, none of whom are showing any symptoms," the ministry said in a statement.
The five arrived in Lebanon last month from the United States via Turkey and from Australia via the United Arab Emirates, according to the health ministry.
The first three cases of the A(H1N1) virus, a Lebanese returning from Spain and two visiting Canadians, were diagnosed late in May.
Swine flu has now spread to 73 countries with over 25,200 people known to have been infected and 139 to have died since the disease was uncovered in April, the WHO said on Monday.
