QUINCY — In response to a case of novel coronavirus that killed a Quincy man in his 80s, who death was announced Sunday, local organizations are taking steps to help stop the spread of the virus, also called COVID-19, in places visited by that person.

The resident, whose name and gender has not been publicly released, had traveled to public events at the Quincy Senior Center from Feb. 13-28 and Quincy High School Feb. 21, the Grant County Health District wrote in a statement.

The resident attended the following events at the senior center: a Valentine’s Day Dance on Feb. 13, lunches on Feb. 14 and 21, line dancing Feb. 17 and Feb. 24, SAIL classes on Feb. 18 and 20, a lunch and movie night Feb. 25, and dinners Feb. 27 and 28.

The resident also attended a Feb. 21 production of “Mary Poppins” at the Quincy High School theater.

In response, Quincy High School has taken the precaution of cleaning the performing arts center, sterilizing objects like doorknobs that are commonly touched, district Superintendent John Boyd said in an interview. The school’s choir has been asked to conduct its practices at the nearby middle school while the facility is sterilized, Boyd added. The school is also discussing possible next steps about postponing or canceling large public events, though no decision was announced by press time.

As of midday Monday, no school employees were in the process of seeking a test to see if they had been infected with the virus, Boyd said. However, if employees who had contact with or were near the Quincy patient begin to show symptoms of the disease, that may change.

The Feb. 21 production of “Mary Poppins” occurred 17 days ago, and best estimates from the World Health Organization state that the incubation period for the novel coronavirus is likely one to 14 days. A study published Monday from the Johns Hopkins Bloomberg School of Public Health suggested that 97.5 percent of coronavirus patients will show symptoms within 11.5 days.

“Of course we’re concerned in case things ramp up,” Boyd said. “Our health care professionals are on it, we’re in communication with them, and I trust they’re doing what they can.”

For its part, the senior center has closed its doors until March 16, according to Director Stacia Soukup, and has hired professional cleaning services to disinfect the facility. The facility holds regular, well-attended events for senior citizens in the area, Soukup said.

“We’re not over the hump yet,” Soukup said. “We are a very busy senior center. We just wanted to make sure that, when we reopen, there’s no chance the virus is still around.”

In an interview, Quincy City Administrator Pat Haley said that while there had been a spike in city staff requesting sick leave Monday, he believes the requests were a general precaution. Haley added that no official directives have been given for how city staff should respond to the Quincy case, though he noted staffers have been gravitating toward the office hand sanitizer.
