As the number of coronavirus cases escalated this week in Williamson County, the Round Rock school district extended school and office closures to April 13 and indicated the spring semester could be canceled altogether.


On Wednesday, Williamson health officials confirmed 22 cases of the coronavirus in the county, or three additional cases than its previous update on Tuesday.


One person has recovered and four have been hospitalized, the Williamson County and Cities Health District said in a news release.


The number of cases in Round Rock increased from three to six. Northwest Austin has three cases, Cedar Park has five, Georgetown has six and Leander has two, the health district said.


Nine of the confirmed cases are in men and 13 are in women, according to the Health District.


Leander, Liberty Hill, Jarrell and Taylor so far have no cases of the coronavirus.


Travis County health officials on Wednesday confirmed 119 coronavirus cases, a jump they said was in part due to increased testing.


Later Wednesday, Round Rock school district Superintendent Steve Flores notified parents in an open letter that school closures would extend to April 13 and opened the possibility of the entire spring semester being canceled.


“Throughout Spring Break and during this school closure, District and campus leadership have been working together to prepare for that possibility and ensure that all students will continue to receive a robust and engaging educational experience,” Flores said. “Much of the work has been and is focused on finalizing our transition to an at-home learning platform and training educators prior to April 5, while developing a strategy to ensure device and internet access for our students who may not have these resources readily available.”


In a media briefing on Tuesday, Williamson and Travis county officials recommended districts canceling the spring semester to forestall the spread of coronavirus. Mark Escott, interim director of Austin Public Health, said the closures would decrease the strain on the local health care system as more people are hospitalized due to the virus.


Also on Wednesday, President Donald Trump issued a major disaster declaration for Texas, which Gov. Greg Abbott said will pave the way for access to additional federal resources.


“GREAT NEWS,” Abbott tweeted. “President Trump just granted a Major Disaster Declaration for Texas. This will expand the resources available to Texas & speed our ability to robustly respond to #coronavirus.”


A major disaster declaration gives the state access to federal assistance programs for both emergency and permanent work, according to the Federal Emergency Management Agency, and signifies that Trump believes the coronavirus has caused damage to an extent that a proper response is beyond the capabilities of state and local governments.


“The president’s declaration opens up new sources of funding for individual and public assistance that will help Texas respond to this public health emergency and protect public health and safety,” Abbott said in a statement.


According to a White House news release, the declaration will make federal funding available for crisis counseling for affected individuals across the state. The declaration also makes federal funding available to the state, eligible local governments and certain private, nonprofit organizations for emergency protective measures.
