UPDATE 9:15 P.M.: A student at Tiger Tots Academy in Columbia has tested positive for COVID-19, according to the owner Paul Prevo.
The preschool posted details on its Facebook page Thursday. The post said that the child was asymptomatic and attended Tiger Tots' west location.
The post said that the health department notified the preschool Thursday about the student.
The student was tested through contact tracing after having contact with someone outside of Tiger Tots, according to the preschool.
"The consistent effort to follow stable group and staffing procedures, as well as stringent sanitation and disinfecting processes, has been successful in limiting this exposure to a very small group of Tiger Tots’ students and teachers," the post said. "All teachers and parents with a student potentially affected by this situation have been personally contacted by administration and will be working with the Boone County Health Department to quarantine for 14 days."
UPDATE 5:25 P.M.: Another worker at a Columbia hydraulics factory has tested positive for COVID-19.

A company spokeswoman said the worker is in quarantine and activity in the area of the factory where that person worked was suspended until it could be disinfected. Employees who had close contact with the worker in the two days before the positive test are being told to isolate themselves for 14 days or until they test negative, the spokeswoman said.
The factory was closed Tuesday for a deep cleaning. It has since reopened.
The spokeswoman said Gates has instituted enhanced cleaning and sanitation, reduced employee density and is checking employees' temperatures multiple times per day.
UPDATE 5:15 P.M.: The Columbia/Boone County Health Department said COVID-19 cases in the county increased by nine on Thursday instead of eight.

With the revision, cases increased by six on Wednesday, instead of seven, and by nine on Thursday, instead of eight.
Boone County has seen the eighth-highest increase in cases among all the counties in the state over the last seven days, according to state numbers.

Company spokesman Michael Mullen had earlier said a worker at the Columbia plant had tested positive, but followed up with ABC 17 News to say the company is treating the case as a "presumptive positive" for COVID-19.
A test had not confirmed the infection as of Thursday afternoon but the company was treating the case as if the worker has COVID-19, Mullen said.
UPDATE 2:45 P.M.: An employee of the Kraft Heinz factory in Columbia has tested positive for COVID-19, the company said in a statement.
One employee has tested positive and is in self-quarantine at home with full pay, Kraft Heinz spokesman Michael Mullen said.
"We have taken all necessary steps to identify and notify individuals who worked closely with this (employee). We have taken several proactive measures to ensure the wellbeing of our people and to help reduce the risk of virus exposure or transmission," Mullen said in the statement.
Those measures include disinfecting and sanitizing surfaces touched by employees every four hours and regular deep cleaning of production lines; signs encouraging social distancing; redesigned break rooms and staggered break times; providing face masks to all employees and checking all employees for fevers and other symptoms as they enter work.
Mullen said the company has asked employees to stay home if they don't feel well since the start of the COVID-19 pandemic.
The Columbia plant makes hot dogs.
UPDATE 2:10 P.M.: Boone and Audrain counties are among the top 10 for COVID-19 case growth in Missouri, according to the Missouri Department of Health and Human Services.
Audrain County has seen the second-fastest growth in cases over seven days at 42.8 percent, the department reported in its online COVID-19 dashboard. The state counts 70 cases in the county.
