LOS ANGELES — A cruise ship docked in California on Sunday after 172 people on board fell ill with the highly contagious norovirus during a nearly monthlong trip, the Centers for Disease Control and Prevention said.

Some of the more than 4,100 people aboard the Crown Princess began to show signs of the gastrointestinal sickness a few days into the voyage from Los Angeles to Hawaii to Tahiti.

The ill passengers and crew members were treated on the ship.

A CDC official was expected to board the ship to investigate the outbreak and the cruise line's response.

The ship will undergo a deep cleaning at a terminal in San Pedro before embarking on its next voyage to the Mexican Riviera, company spokesman Susan Lomax said.

In April, 129 people on the same ship contracted norovirus during a seven-day cruise off the California coast. Lomax said that the ship went through the same stringent disinfecting process after it docked.

According to the CDC, most people recover within three days.

DETROIT — The lawyer hired by General Motors to compensate victims of crashes caused by faulty ignition switches is giving people another month to file claims.Kenneth Feinberg announced Sunday night that the deadline has been extended until Jan. 31, 2015.The company came under fire last week because the family of a Connecticut woman who died in a 2003 crash had not been notified that her crash had been linked to a faulty switch, even though GM knew for years.Feinberg said in a statement that the extension is being done out of an abundance of caution, even though many efforts have been made to reach owners of 2.6 million Chevrolet Cobalts, Saturn Ions and other small cars that have been recalled due to the defective switches.He said notices about the compensation fund have been sent to nearly 4.5 million current and prior owners of the cars.
