0 00:00:03.045 --> 00:00:06.845 Next, I will briefly explain how to prevent from catching COVID 1 00:00:06.845 --> 00:00:09.012 The most important thing is the mask 2 00:00:09.012 --> 00:00:12.544 (#Prevention - Mask) I recommend KF94 or higher 3 00:00:12.544 --> 00:00:17.614 (A mask that can filter KF94 or higher and 0.4 micrometer or less is recommended) In other words, we recommend a mask that can filter less than 0.4 microns 4 00:00:17.614 --> 00:00:20.546 It's a problem when you take it off 5 00:00:20.546 --> 00:00:24.298 (It is also important to how to take off the mask) Because we wear a mask and inhale 6 00:00:24.298 --> 00:00:27.999 (You have to hold the string on your ears and throw it in the trash after removing it) There must be a virus on the surface 7 00:00:27.999 --> 00:00:31.078 So when you take it off, you shouldn't take it off like this 8 00:00:31.078 --> 00:00:38.542 When taking off, remove the straps from your ears first, then hold only the straps and throw them in the trash 9 00:00:38.542 --> 00:00:40.383 (Be careful of sealing the outer surface of the mask) And now if you put on a mask 10 00:00:40.383 --> 00:00:42.317 (Be careful of sealing the outer surface of the mask) You all have used it, right? 11 00:00:42.317 --> 00:00:52.269 When you inhale after wearing it, can you feel the air seeping in like this, especially around the nose, cheeks, or chin, correct? 12 00:00:52.269 --> 00:00:57.045 The aerosol is 0.6 micrometers in size, so you can't see it 13 00:00:57.045 --> 00:01:01.895 If this is leaking, wearing a mask doesn't help you, right? 14 00:01:01.895 --> 00:01:09.535 So, always pay attention to sealing when wearing a mask, especially around the nose 15 00:01:09.535 --> 00:01:12.131 (#Prevention - Washing Hands) Next, hand washing is important 16 00:01:12.131 --> 00:01:19.231 All of you are good at washing your hands, but from what you see in this picture, you are not good at 6, 7, 8, and 9 17 00:01:19.231 --> 00:01:24.719 When you wash your hands, you are now doing well with the palms, the back of your hands, and between your hands 18 00:01:24.719 --> 00:01:26.799 But there is something we miss out on 19 00:01:26.799 --> 00:01:34.087 (Parts often missed in hand washing - fingertips, between fingernails, thumbs, wrists) It's the tip of the hand, between the fingernails, then the thumb and wrist 20 00:01:34.087 --> 00:01:41.142 In order to clean your fingertips well, you have to rub them well in a shape like this 21 00:01:41.142 --> 00:01:45.158 Then you must wash your thumbs separately 22 00:01:45.158 --> 00:01:47.050 Many people miss this part a lot 23 00:01:47.050 --> 00:01:54.706 After that, you should try to remove the virus caught between your nails by rubbing your nails well with your palms 24 00:01:54.706 --> 00:02:03.773 And by wiping the wrist separately, it is safe to wipe the virus from this wrist to the forearm as well 25 00:02:03.773 --> 00:02:06.892 (#Prevention - Disinfect Surroundings) Next, you need to disinfect the surroundings well 26 00:02:06.892 --> 00:02:09.972 (Keep Things Clean) In the case of an aerosol, it was said that they float for 16 hours 27 00:02:09.972 --> 00:02:17.133 That's why it's important to always keep the things around you clean regardless of the distance 28 00:02:17.133 --> 00:02:23.021 (Lack of vitamin D can cause severe lung symptoms) There are also reports of severe lung symptoms in the case of vitamin D deficiency 29 00:02:23.021 --> 00:02:26.445 Vitamin D, so vitamin intake is also important 30 00:02:26.445 --> 00:02:30.936 (#Prevention - Air Purifier) When using an air purifier, it can filter up to 0.3 micrometers 31 00:02:30.936 --> 00:02:35.116 (HEPA filter level filter is used) It would be nice to be able to use a HEPA filter level filter 32 00:02:35.116 --> 00:02:37.841 (Ventilation reduces the density of the coronavirus) By ventilation, the coronavirus itself 33 00:02:37.841 --> 00:02:40.729 It would also be important to reduce the density 34 00:02:40.729 --> 00:02:43.248 (#Prevention - Eat Cooked Food) Eating cooked food is also important 35 00:02:43.248 --> 00:02:46.517 For example, when we eat, especially outside 36 00:02:46.517 --> 00:02:50.797 (There is a risk of contamination of coronavirus during serving or cooking) While serving or preparing food 37 00:02:50.797 --> 00:02:56.688 Since contamination with this coronavirus is quite possible 38 00:02:56.688 --> 00:03:00.220 (Recommended to eat hot food) It is better to eat food that is a little hot at the moment we eat 39 00:03:00.220 --> 00:03:03.560 Because the virus is easily killed by high heat 40 00:03:03.560 --> 00:03:10.652 I think it is safer to eat hot food than raw or lukewarm food 41 00:03:10.652 --> 00:03:12.660 (#Prevention - Pay Attention to the Bathroom Environment) The bathroom is also important 42 00:03:12.660 --> 00:03:15.256 If you flush the toilet 43 00:03:15.256 --> 00:03:21.255 (Aerosol is generated over the toilet) You can't see it, but a lot of aerosol is generated over the toilet 44 00:03:21.255 --> 00:03:26.683 The top of the toilet is full of aerosol, which eventually fills the entire toilet 45 00:03:26.683 --> 00:03:32.351 (Virus occurs in feces of patients with COVID-19) More than half of COVID-19 patients have the virus in their feces 46 00:03:32.351 --> 00:03:38.999 To put it simply, when a COVID-19 patient flushes the toilet, aerosols are generated 47 00:03:38.999 --> 00:03:43.211 It can spread throughout the bathroom mixed with the virus 48 00:03:43.211 --> 00:03:49.151 (Wear a mask even in the bathroom) You should wear a mask well in the bathroom and pay attention to hand hygiene 49 00:03:49.151 --> 00:03:51.547 (#Prevention - Vaccine) Finally, a vaccine 50 00:03:51.547 --> 00:03:54.859 Vaccines are being distributed now 51 00:03:54.859 --> 00:03:58.659 (In the future, mutations such as the South African variant will continue) Variants like the South African variant will continue to appear in the future 52 00:03:58.659 --> 00:04:01.895 Coronaviruses are characteristically mutable 53 00:04:01.895 --> 00:04:08.411 The vaccine, which is currently available, is known to cover the strains from South Africa 54 00:04:08.411 --> 00:04:11.039 But it's just a little weaker 55 00:04:11.039 --> 00:04:15.155 (3rd dose may be required) So, this vaccine is currently being planned as a second vaccination 56 00:04:15.155 --> 00:04:18.475 But it is highly likely that the third vaccination will be given 57 00:04:18.475 --> 00:04:27.526 And based on the age of 55 years old, immunity to antibodies is expected to be maintained for about 6 months, between 6 months and 1 year 58 00:04:27.526 --> 00:04:34.659 (Expect annual vaccination) Therefore, it is expected that you will need to get a vaccine against coronavirus every year 59 00:04:34.659 --> 00:04:41.326 (#Isolation Release CDC Guidelines - Mild/Moderate Patients) Finally, we will explain when you can be released from quarantine after getting sick with COVID-19 60 00:04:41.326 --> 00:04:46.850 Mild or moderate patients, those who doesn't need to go to the hospital 61 00:04:46.850 --> 00:04:52.210 (10 to 20 days or more after symptom onset, no fever for more than 24 hours, improvement of existing symptoms) 10 to 20 days or more have passed since the onset of symptoms 62 00:04:52.210 --> 00:04:56.222 10 days or 20 days, the difference is now for the doctor to decide 63 00:04:56.222 --> 00:05:02.522 If there is no fever at all without taking antipyretics for 24 hours 64 00:05:02.522 --> 00:05:07.742 You can be released from isolation if your existing symptoms improve 65 00:05:07.742 --> 00:05:12.030 (#Isolation Release CDC Guidelines - Immunocompromised Patients, Critical Care Patients) On the other hand, in immunosuppressed or critically ill patients 66 00:05:12.030 --> 00:05:15.650 (Requires PCR test) The PCR test is called a heavy pressure enzyme chain reaction test 67 00:05:15.650 --> 00:05:21.670 To put it simply, you can only be released from quarantine if you have a negative result in the gene amplification audit 68 00:05:21.670 --> 00:05:24.961 If you summarize this immunocompromised patient, critically ill patient 69 00:05:24.961 --> 00:05:30.705 (Age 55 or older, diabetic, dialysis patient, AIDS, chemotherapy) Patients over the age of 55, and those with diabetes or undergoing dialysis 70 00:05:30.705 --> 00:05:34.213 (Admission to intensive care unit, administration of steroids for more than 14 days) AIDS patients or those who have undergone chemotherapy 71 00:05:34.213 --> 00:05:42.213 And those who were hospitalized in an intensive care unit or who received steroid treatment for more than 14 days are defined as immunocompromised patients or critically ill patients 72 00:05:42.213 --> 00:05:45.601 (#Isolation Release CDC Guidance - Reasons for this Difference) To explain the reason for this difference 73 00:05:45.601 --> 00:05:49.661 (Although a healthy person can be PCR positive for up to 3 months) Once a healthy person has been reported 74 00:05:49.661 --> 00:05:54.517 (The infectivity is very low, so there is no evidence that it has infected others.) There have been cases where the PCR test was positive for up to 3 months 75 00:05:54.517 --> 00:06:02.624 But in healthy people, if it's been more than 20 days, even if the virus comes out, the virus has very low infectivity 76 00:06:02.624 --> 00:06:07.793 There is no evidence that this virus could infect anyone else 77 00:06:07.793 --> 00:06:12.632 There is no evidence, there is no case, and that's why quarantine can be released 78 00:06:12.632 --> 00:06:16.612 (Even if symptoms disappear in immunocompromised patients) The reason why PCR testing necessary in immunocompromised patients is 79 00:06:16.612 --> 00:06:20.016 (Infectious viruses may be alive) Even if the symptoms disappear completely in these people 80 00:06:20.016 --> 00:06:27.908 Viruses from these people are still considered infectious, so PCR testing is essential 81 00:06:27.908 --> 00:06:32.060 The COVID-19 pandemic is almost over 82 00:06:32.060 --> 00:06:36.240 Vaccine is out, and it's expect to be calm down soon 83 00:06:36.240 --> 00:06:40.816 I pray that you have a safe trip during the remaining time 84 00:06:40.816 --> 00:06:42.797 Thank you
