When I'm on the night shift, all the department heads can't sleep.

The Qiaodong Community Health Service Center double-checked the 43 minutes that Cheng Hao had spent in the infusion observation area.

At 11:44, he accompanied his mother inside. At 11:50, the elderly woman began her IV drip. At 12:19, the community health service center received a call from the local authorities. At 12:27, Cheng Hao was taken to a private consultation room at the back.

The surveillance footage and infusion records were checked together. During that period, there were a total of nineteen people in the observation area, including patients and their companions.

Ten of them were receiving intravenous infusions, and nine were accompanying family members. Two nurses and one cleaner who had worked in the observation area that day were registered separately and were not included in the list of nineteen people.

The temperature check records at the entrance, the infusion slip, and the payment receipt all match the time, and there are currently no gaps in the identity records on site.

After receiving a call from the local authorities, the on-duty doctor, Qiao Ning, instructed the nurses in the infusion area to stop allowing patients to enter through the side door.

She told the people in the hall that they needed to complete the registration process again and asked everyone to prepare their ID cards and mobile phone numbers.

Several people who had already finished their IV drips became anxious when they heard that they couldn't leave immediately.

"I have to pick up my child this afternoon, why are you leaving me here?"

"I've finished administering the medication, and I haven't spoken to that person at all."

Qiao Ning stood at the entrance of the infusion area and explained, "What we need to verify is who was here at the same time and where they were sitting. After registration, the arrangements will be determined on-site by the local staff. If you leave now, your family will have to search for you later."

An elderly man got up to remove the IV needle from the back of his hand, and the nurse quickly grabbed his raised hand: "There's still some medicine left, don't pull it out yourself. If you need to pick up your child, give us your phone number so we can let you know in advance."

The young mother next to her actually gave out the kindergarten teacher's number.

The nurse used her work phone to explain that she couldn't leave temporarily and asked the teacher to let the child stay in the duty room. After hanging up, she didn't go towards the door but sat back down in her original spot to wait for registration.

The scene gradually quieted down.

Cheng Hao's spot was near the water dispenser.

The surveillance footage showed that he once fetched hot water for his mother and went to the nurses' station to inquire about the IV drip rate. Apart from that, he spent most of the time sitting next to the elderly woman and did not walk back and forth between the rows of seats.

In the private consultation room, Qiao Ning asked about the medication time and changes in symptoms.

Cheng Hao had taken an ibuprofen tablet at nine o'clock in the morning. His temperature was 37.4 degrees Celsius when he entered the room. He registered as an accompanying family member.

The sore throat and chills gradually worsened after he sat down. He originally planned to have his mother's IV drip finished before having her see a general practitioner.

Cheng Hao's mother still had that bottle of medicine hanging from her arm.

The nurse moved her to another room for continued observation, rechecked her blood pressure, and made her put on a mask again.

The elderly woman asked her son through the door if he had caused trouble, but Cheng Hao couldn't answer. He then reminded her through the door not to pull out the needle herself.

Qiao Ning reported the medication time, body temperature upon entry, and changes in symptoms to the local authorities.

The identification of close contacts is the responsibility of the local authorities, and community health service centers will continue to maintain order and provide medical care.

Local personnel will take over the registration upon arrival.

The sampling staff first collected samples from Cheng Hao and his mother, and then checked the seating positions, arrival times and contact numbers of the nineteen patients and their companions. Two nurses and a cleaner made separate records.

Whether the remaining individuals will be sampled or remain at home will be determined by the local authorities based on their contact history.

This information was returned to Song Lan through the disease control liaison channel.

The staff of the community health service center will continue to be managed by the local authorities, and the hospital list verification office will retain Cheng Hao's name, arrival time, and local feedback number in the off-site assistance column.

Ma Hao filled in the community receipt number and then included the details of the nineteen people in the outpatient assistance directory. The hospital's list page only retained the receipt number.

"The people at the hospital haven't finished testing yet, and if we cramm in all nineteen more from the community, nobody will be able to tell them apart this afternoon."

Song Lan checked the document's origin: "A receipt number is enough. Further cooperation from the hospital is needed, and the local authorities will specify the exact name."

Before 1 p.m., the identities and contact information of all nineteen people had been verified.

The five patients who had finished their IV infusions were moved to another waiting room to await further instructions from the local authorities, while the remaining patients continued to be cared for by their original nurses.

The nurse changed the masks for the five people and led them through the inner passage of the observation area, without passing through the front waiting area.

Outpatients with appointments should now use the front entrance. The infusion observation area will temporarily suspend accepting new patients. Cleaning and disinfection will be carried out according to local requirements only after all patients have left.

Qiao Ning gave the names of the on-duty medical staff, the seat Cheng Hao had sat in, and the time the water dispenser was used to the on-site personnel.

When the last registration form was collected, no one left the infusion area on their own, and no more unidentified accompanying persons appeared.

At 1:07 PM, Zhou Min called from the emergency room day shift. Gao Yuan's retest result was confirmed positive, and the official report had been uploaded.

After Zhou Min finished reporting the results, she read the report number aloud again, and Song Lan checked it on the spot.

"The fever clinic is informing him," Zhou Min said. "His travel route remains separate from Gao Limin's, and their cohabitation relationship is listed separately. Don't combine their hospital locations into one just because both father and son tested positive."

Song Lan added Gao Yuan to the list of officially confirmed positive cases. The number of officially confirmed positive reports related to the Kangning Hotel investigation chain has increased to four.

After listening to the results through the walkie-talkie, Gao Yuan leaned against the observation post without saying a word for a long time.

The nurse asked him if he felt any pain, and he shook his head before realizing that the other person couldn't see him through the door.

"I'm still feeling cold and have a sore throat, but otherwise I'm okay." He moved closer to the intercom. "Where is my dad going next? Can I go to the same hospital as him?"

"Transfer arrangements depend on the patient's condition and available beds," the doctor at the fever clinic replied. "You and your father are currently in the isolation area. If you want to pass messages between each other, a nurse can help, but we cannot guarantee that you will be in the same vehicle or admitted to the same hospital."

After listening, Gao Yuan stuffed his father's retrieval slip back into the file bag: "Then tell him that I've found out too. If he asks me, don't hide it from him."

The doctor at the fever clinic reassessed his temperature, blood oxygen, and respiratory status.

Gao Yuan's body temperature is 38.5 degrees Celsius, his blood oxygen saturation is 96%, and he is conscious. He does not require oxygen therapy for the time being.

His condition differed from Gao Limin's, and their beds and transfer order were arranged separately by the medical treatment team.

After learning the results of his son's diagnosis, Gao Limin remained silent for a while behind his mask, then asked a nurse to tell him, "Tell him to listen to the doctor and not to keep worrying about me."

The father and son remained in different observation positions, and neither could see the other.

The municipal CDC laboratory subsequently reported the initial test results from the orthopedics department on the eighth floor and Chen Xiulan through the testing liaison channel. No relevant targets were detected in the samples from Shao Kai, his son hospitalized with a fracture, and Chen Xiulan.

When Zheng Li told Shao Kai through the ward's work phone, he first breathed a sigh of relief, and then immediately asked if he could get his child discharged from the hospital.

"You can't leave yet," Zheng Li said. "Your family was staying together before, and the ward is still under temporary management. Whether we need to conduct further testing and when the restrictions will be lifted depends on the hospital's infection control department and the local authorities."

Shao Kai glanced in the direction of bed six: "The child can stay here, but I'm afraid his mother won't know anything at home. She won't answer any unfamiliar numbers on her phone."

Zheng Li asked him to tell his wife to keep her phone accessible.

Shao Kai agreed and then asked the nurse to tell his mother that he and his child were both fine. After receiving the message, Chen Xiulan stayed where she was and asked the nurse to remind her grandson not to step on his leg.

The child in bed six, upon hearing that both he and his father had tested negative, was already thinking about taking the high-speed train that afternoon.

Shao Kai told him that the train ticket could be changed, but the plaster cast couldn't be redone. The child pushed the travel bag beside the bed back against the wall and didn't ask when he would leave.

At 1:22 PM, the chief medical officer on duty relayed the consultation results from the municipal-level treatment team.

Xu Wenliang's respiratory rate has increased to 34 breaths per minute, and his blood oxygen saturation remains between 92% and 93% under high-flow humidified oxygen therapy.

After a second evaluation by the respiratory department, it was determined that he needed to be transferred to the intensive care unit of a designated hospital as soon as possible, and a bed was being finalized.

The fever clinic has compiled the most recent blood gas, imaging data, medication records, and oxygen therapy parameters.

The municipal treatment team required a reassessment of the patient's level of consciousness and respiratory support conditions before transfer, and the receiving hospital was required to prepare intensive care beds simultaneously.

The administration building is responsible for registering vehicles and routes, but does not participate in the selection of respiratory support methods.

There was a pause on the other end of the phone, then the voice added, "The negative pressure ambulance has already departed from the designated hospital."
