DUBLIN — A student at Kolb Elementary School died from an unspecified illness, school officials announced Friday.

Dublin Unified School District posted the news on Facebook along with a copy of a letter from the Alameda County Public Health Department indicating that it was investigating the case.

The name of the student has not been released and the school district stated that if any additional information is forthcoming it would be from the county.

Starting Tuesday and for the duration of the week, employees and students at Kolb Elementary will be able to talk to mental health counselors from the Hume Center and other district sites.

In her letter to the district’s assistant superintendent of educational services, Deputy Health Officer Erica Pan said that the county’s investigation does not give health officials reason to believe that Kolb Elementary employees and students were exposed to the illness on campus.

“We do not recommend any specific preventive actions at this time,” Pan wrote.

She emphasized, however, that parents should seek prompt medical attention if their children start showing signs of what could be a serious illness, symptoms ranging from a fever, cough, headache, rash, or sore throat to vomiting, diarrhea, difficulty eating/drinking/breathing, muscle pain and confusion.
