The administrative room, which serves as the department headquarters, is noisy like a market. Health workers from all over the country are present. People dispersed to various corners where we carefully put on our personal protective equipment (PPE). After putting on the PPE, we slowly entered the danger zone, where the patients were waiting. The ward with the most seriously ill patients is the red zone, which is completely isolated since it is the most dangerous. Next is the transition area called the yellow zone, and finally the medical staff's safe base, the briefing room, dubbed the green zone. When going from green to red we must wear the PPE, and when leaving the red zone we must remove the PPE and carefully disinfect it from head to toe before entering the green zone.

We finally entered the ward. With the PPE on, every movement became very difficult, the goggles became foggy, and even breathing was difficult. Every one of the patients was suffering from shortness of breath, coupled with anxiety and panic from witnessing other patients in the room get worse and occasionally pass away. We had to practice speaking and breathing gently to avoid creating strong air flows through our masks, which makes it easy to spread the infection. Nurses struggle to perform venipuncture. Normally very dexterous at drawing blood, here they sometimes need two or three attempts since having to wear multiple pairs of gloves hinder their ability to feel with their fingers. It is also difficult for doctors to examine the patients since they cannot use stethoscopes and must be very brief when asking patients questions. Instead, by observing whether patients breathe gently, with difficulty or abnormally, and noting their facial expressions, sweat, skin color, we can assess the progress of the disease.

As the day went by, severe patients were treated and less severe patients were recovering, and so we finally felt reassured despite being drenched in sweat. Just as it was time for us to return to the green zone to write up medical records, there was a commotion from the room next door. A patient's condition was worsening. All the medical staff in the room rushed in for emergency treatment. After a few minutes the patient's heartbeat returned, and the ventilator was reattached for the patient to resume breathing. My colleagues were covered in sweat as if they had just showered.
