LAS VEGAS -- Nevada OSHA officials have issued eight citations against Summerlin Hospital following an investigation into a tuberculosis outbreak in May 2013 that resulted in 20 employees contracting the disease.

According to the State of Nevada Department of Business & Industry, six of the citations are considered "serious" and two are "other-than' serious." They were issued for multiple safety and health violations.

It was learned during an OSHA investigation that are least two patients with unrecognized active TB were admitted into Summerlin Hospital for treatment. One of the patients was a baby admitted to the Level III Neonatal Intensive Care Unit where employees and other babies were exposed. In all, more around 60 people were diagnosed with the disease.

The investigation found there were "multiple deficiencies" in the hospital's TB Exposure Control Plan. The penalties for the violations total $39,600.

LAS VEGAS (AP) -- A famous southern Nevada tortoise has emerged from his burrow in another sign that spring has begun.

Clark County officials say Mojave Max made his seasonal debut at 4:10 p.m. Monday at the Red Rock Canyon National Conservation Area.

The tortoise goes into hibernation every winter and emerges each spring as his internal clock responds to warmer temperatures and longer daylight hours.

Schoolchildren in the area guess when Max will emerge as part of an annual contest that's been running since 2000. The winning student receives prizes including a year-long pass to national parks, a laptop computer and a digital camera.

The winner has not yet been announced.

The earliest the tortoise has emerged is Feb. 14, and the latest is April 17.
