WASHINGTON — A United States health official on Saturday did not rule out the possibility that the Influenza A (H1N1) virus outbreak may have originated in California.

“As we do our investigations here in the US, we may find that there were cases earlier,” said US Centers for Disease Control and Protection spokesman Scott Bryan.

Several cases of infection were reported in California before the outbreak in Mexico, the epicentre of the flu outbreak.

The number of confirmed H1N1 cases in the US stands at 197, including one death.

The first case discovered in California was a 10-year-old boy in San Diego County, which borders Mexico, who became ill on March 30 — before the outbreak in Mexico, reported The Wall Street Journal.

In a second case, a nine-year-old girl from a nearby California county was treated for a cough and a high fever on March 28.

On April 17, tests confirmed that the girl did indeed have the new virus strain, reported the Journal. The children, who had not travelled to Mexico or come into contact with pigs, have since recovered.

The potentially deadly virus is a hybrid drawn from strains found in pigs, birds and humans. AFP
