Mrs French Caught in the air from the air in front of the room Revealed 2 more infected people in the room close to each other. Yeast can fly onto the table in front of the room. Or in food containers
November 6, 2020 Dr. Opaskarn Kawinpong, MD. The Acting Director General of the Department of Disease Control (Khor.), Ministry of Public Health (Ministry of Public Health), said that there will be 3 types of COVID-19 situations in Thailand: 1. The peak is that there is an infection and no more infection, like Restaurant dj case Y French lady in Koh Samui Who did not find any additional infected contacts
2. Spike & Small Wave: 1-2 people got infected and no more than 50 people got infected per day, as in Burma with Mae Sot infection. It is in a family of 5 and can be controlled and 3. Spike & Big Wave is an infection that is not well controlled. People do not cooperate with disease control and wear masks. And a severe outbreak.But in the past, Thailand has never happened like this and it is believed that it will never allow that to happen.
Follow the news, press follow the line fresh news
Dr. Opas He said that in the case of a French woman who was presumed to have been infected in an Alternative State Quarantine, three infected people were now decrypted at the same ASQ and were in a nearby room, with relevant experts to consider the data. Found that the 3 cases belonged to the same infection group Same species Because the genetic code is the same
It translates to mean that the infection in these 3 cases is linked AND there is an assumption that The cause of the infection is probably due to poor ventilation. And the infection can be in the central area and become contaminated Here you need to check more. If there is progress, more statements will be made. But you have to reiterate the quarantine center to focus on cleanliness Take care of common areas AND an efficient ventilation system It will be safer
Dr. Walairat Chaifu, MD. The director of the Epidemiology Division said no further investigations were found on the disease, a 57-year-old French woman who followed a contact in a quarantined hotel. The part that was detected in the gym was the remains of contagion. When checking again, it cannot be found. And it has been cleaned Considered unrelated Because the patient did not have access to the service The question is how to get stuck? For the same period of detention There are 2 other cases of strange infection, while the third one comes later, so there is no connection and the infection is from different strains.
“The genetic code of two other French and foreign women discovered that they were of the same species. Most of the code is the same. It is believed that these three people may be related. Therefore, we have to go back and investigate the systems that can cause transmission of the infection in the hotel, ”said Dr. Walairat.
Dr. Walairat He said that the system to examine was 1. Air system It was found to be a circulation system in the room. Unable to cross the room 2. Room ventilation system There is an exhaust fan in the bathroom. Attached to the power switch The system will work when turned on. The air inlet has a back pressure shield to the chamber or valve cover. Causing the outside wind cannot return to the bathroom AND the end of the pipe is connected to the pipe connected to the platform. Therefore, there should be no air passing through the exhaust fan.
Y 3. Sewer system When SARS had a case of this type, it was discovered that there was a central U-tap in each room and that it was a pipe that was placed vertically. But the room found was on the same horizontal level, so it was impossible to mount it between the floors.
“Looking at the layout of the room The room where the 3 infected people live next to each other. The French woman stayed in room 307, she stayed on October 8, she left ASQ on October 15, another foreigner stayed in room 609, it was a room next to a French woman, she arrived on October 8, it was detected on 19. Oct. and a second foreigner stays in room 631 on the opposite side of a French woman. It entered on October 12 and was detected on October 15.
Therefore, the three rooms have a time together, October 12-15, so they have to come and see if they can broadcast or not. Engineers and the Bamrasnaradura Institute helped investigate. There is an assumption that the infection can be transmitted through the air in front of the room after room 631 has opened the door. Because he was the first person to find the infection, “Dr. Walairat said.
Dr. Walairat Said when opening the door of the room. The yeast floating in the room was blown into the air in the hallway. Which is normally released to ventilate the mold. But the COVID period is not open Leave the air very still Bacteria can stay in the air for up to 3 hours. Also in that hallway Between the rooms are 1.8 meters apart, each room has a dining table facing the room. The infection may be airborne or landed on a table in front of the room. Or in food containers
We are currently investigating all three. When leaving the room with or without a mask, do you touch something? What a French woman said When going out to wear a mask every time And the other question did not find the patient She is in the process of finding the next answer Now I will wait for the results of the air vents and the air vents that there is a leak or not . And ask again about the patient’s behavior in the room and the hotel to get more conclusions.
