Laos confirmed four more influenza A/H1N1 cases, bringing the country's tally to seven, Lao newspaper the Vientiane Times reported on Monday.

Among the newly confirmed cases, one patient is a student coming back from New Zealand. He was tested positive to the A/H1N1virus after showing high body temperature, said the newspaper.

The three others are school boys in Laos' capital of Vientiane. They went to Thailand for a sport event with a group of other seven children. Two of them were tested positive with the A/H1N1 virus in Thailand on June 30 and treated with the influenza drug Tamiflu before returning to Laos. The third was found positive with the virus in Laos on Friday.

Bounlay Phommasack, Head of Lao National Emerging Infectious Disease Coordination Office said the health of the three boys was improving.

All of the 10 children going to Thailand for the sport event have been told to stay at home while doctors monitor their health.
