A three-year-old boy was admitted to Shriners Hospitals for Children Northern California Tuesday night. The boy has burns over 80-percent of his body. 

He joins three other toddlers being treated in Sacramento for serious burns they suffered in last week's fire in Hermosillo. Hospital spokeswoman Catherine Curran says they may be admitting more children. 

“We continue to monitor the situation and are working closely with the medical team in Mexico. We’ve actually sent a team down to Hermocillo to evaluate and assist with triage. So, we’re here to help those children.” 

The hospital’s pediatric burn center provides free care for children not only in Northern California but in Mexico, Canada and the Western US. 

The day-care center fire in Hermosillo killed 44 children, and dozens more remain hospitalized in Mexico.
