The Wall Street Journal: The family of a 5-year-old boy claim he was the first person confirmed with Mexico's swine flu.

Edgar Hernandez lives in the southern Mexican town of La Gloria, where more than 450 people -- out of a population of 3,000 -- have complained of respiratory problems.

After tests, the little boy was the only one found to be positive for swine flu -- his parents and 3-year-old brother were also tested, but they did not have the virus.

Health officials tested other residents complaining of respiratory problems and concluded they had ordinary influenza.

Edgar got sick in late March or early April and recovered after a few days.
