A 14-year-old schoolboy in Mondulkiri’s Sen Monorom town has been diagnosed with the A(H1N1) influenza virus, commonly known as swine flu, raising the tally for the province to three, a provincial health official said Sunday. Lek Sovannarath, director of Mondulkiri’s communicable disease control office, said Sunday that the boy had been hospitalised in Mondulkiri provincial hospital for a week. The test results from Phnom Penh’s Pasteur Institute came back on Friday, he said. Though there have been just two other cases in the province, Lek Sovannarath said provincial health officials “should not be imprudent” in their fight against the disease, adding that they would continue to instruct villagers to wear masks. Ly Sovann, deputy director of the Ministry of Health’s Communicable Diseases Control Department, said Sunday that he had not received any information on the Mondulkiri case. He said there had been 557 cases of swine flu, leading to six fatalities, between June 2009 and the end of January.
