"I am afraid of getting infected and the virus leaking out of the hospital," said Suparvadee, who has been working for 14 years in the intensive care unit (ICU).
But despite her worry, she is encouraging hope for patients.
"I continue to tell patients they don't fight alone," she said.
The job of the Suparvadee involves knowing every detail of the condition of each patient. The novel outbreak of coronavirus also forced staff to learn a new workflow, because none of them had experience with this type of virus, she said.
Her hospital has treated nearly 200 patients suffering from coronavirus since March 9. Staff take pride in not losing a single one.
The hospital is also paying close attention to preventing employee infections.
While fully suited in protective gear, through their 12-hour shifts, Suparvadee guides its junior nurses on safety measures.
Thailand reported on Wednesday nine new coronavirus infections but no deaths since the outbreak began in January, taking its tally to 2,947 cases and 54 deaths.
Suparvadee's husband, 37-year-old Udomsak Tantrarattanapong said he understood her work and supported her.
"I told her to keep fighting because she gets through it just fine whenever something new happens-and I'm sure she'll do that this time too," Udomsak said.
