The new crown pneumonia epidemic in Hong Kong continues. The Sanatorium and Hospital has recently exploded. A 77-year-old female patient with cancer at the end of the stage died after being infected.
Professor Yuan Guoyong of the Department of Microbiology of the University of Hong Kong visited the Sanatorium and Hospital today (2nd) and said that the family of the deceased patient had been to the fitness center before visiting her. Someone in the fitness center belonged to a "singing and dancing group." Infected two other family members who did not wear a mask and ate Pizza during their visit.
In addition, another patient at the dialysis center of Yanghe has a preliminary diagnosis. Yuan Guoyong pointed out that after investigation, it was found that the first confirmed dialysis patient had eaten sandwiches without the cover, and infected the adjacent bed patient through the air.
A terminal cancer patient who was hospitalized on the 33rd floor of the Sanatorium and Hospital earlier tested positive on the evening of November 26 and passed away. Two doctors and nurses also contracted the disease.
Yuan Guoyong pointed out that the investigation found that the family members who had visited the site had been to the fitness center before, and that the center had been visited by patients belonging to the singing and dancing group, and believed that they had contracted the virus here.
Later, the terminal cancer patient infected two other family members.
Later investigations revealed that a nurse pointed out that when the family of the deceased visited, they did not wear a mask or "Pizza".
Yuan Guoyong reminded once again that many confirmed cases involve not wearing a mask and eating, and hope that the public can "wear a good mask", otherwise the risk is very high.
The nursing and has requested that the visiting patient be tested first
After the outbreak, the Sanatorium and Hospital announced that from today (2nd) onwards, all visitors are required to pass the virus antigen screening before they can visit inpatients, and they need to be screened again regularly. If the visitor virus antigen screening result is positive, It must be verified by real-time nucleic acid testing.
Specialist outpatients who need to take off their masks for treatment or medical procedures will also receive the 2019 coronavirus antigen screening first.
Dialysis patients eat through the air to spread poison
Regarding the dialysis center, Yuan Guoyong pointed out that, as a precaution, he had decided to require patients at the center to be tested on the first, fourth and eighth days because the patient’s immune system was poor and the second confirmed case was also confirmed. It is expected, "I believe it is just an extension of the last confirmed case." He pointed out that the first 72-year-old male patient with dialysis who was diagnosed with a mask had eaten a sandwich for 15 minutes after removing the mask, and the second initially confirmed 86-year-old female patient next to the bed I haven’t talked, I believe it was spread through the air. "It only takes 15 minutes, which is enough to infect another patient."
Independent packaging of dialysis machine instrument pipes
Yuan Guoyong analyzed that the female patient was diagnosed only after 8 days apart, which proved that the viral load caused by it was quite low, with a CT value of about 27. "It's not too high."
The two hospital beds are 1.5 meters apart, and there are gaps in the partition curtain. The ventilation in this center is stronger than that in ordinary wards. The air system changes more than 12 times per hour. The kidney dialysis opportunities in this center are shared, but all parts and pipes are individually packaged. The hand hygiene of nurses is also adequate, so it is not transmitted through blood, but the greatest chance is through air transmission.
He explained that short-distance airborne particles are as fine as 5 microns and will be diluted by air. The closer the particles are, the higher the density.
The center has 58 patients undergoing dialysis. At present, dialysis is only possible after completing the test each time. Patients in the center will be monitored all the time, and the infected area will be suspended for 14 days.
He praised the United Hospital's anti-infection measures to "make the most of it."
Other areas that have been disinfected will continue to serve patients.
Relevant measures will continue. Currently, patients are tested every 4 days, hoping to find out as soon as possible.

At the peak of the fourth wave, there are more than 120 bursts per day
Yuan Guoyong said that there have been more than 100 confirmed cases today. "Everyone must understand that what happened today is what happened in the past 7 to 14 days." It is expected that after the government tightens social measures, it is believed that the effect will appear after the 14th. People are urged to stay. Don’t eat together at home, because winter is good for the survival of the virus. It is expected that there will be 120 cases at any time every day or at the peak. The cooperation between restaurants and citizens is believed to be controlled.
He described the fight against the epidemic as a "half marathon" so far. It is expected that vaccines will be distributed to all of Hong Kong by the end of next year. He understands that everyone is working hard, but he hopes that everyone will cooperate and do their civic responsibilities.
