The global COVID situation has come back to haunt once more. and still continue to find outbreaks especially the species “Omicron” The current epidemic has been around for 1 year and has mutated into more than 500 different subspecies, each of which has a different malignancy. Currently, Thailand is one of the countries that are facing a new wave of epidemics fromOmicron especially the species “BA.2.75“ which found a greater proportion until it became the main breed in the country instead BA.5 also gone BA.2.75 There is still an indication advantage in the epidemic. This is part of the fact that the number of infected people in the country tends to increase during this time. make people who have previously been infected with this strain can get sick once more!!!
“BA.2.75” I’m not good at escaping the landscape But why is it so good to spread?
Dr. Anant Chongkaewwatana, virologist Director of Animal Health Innovation and Management Research Group National Center for Genetic Engineering and Biotechnology (Biotech) Post a message on Facebook. “Anan Jongkaewwattana” Stated that research has come out that matches the current situation in Thailand. because I was wondering why BA.2.75 replaced by the main species BA.5 Yes, in spite of the results of several laboratory tests that this strain of the virus does not have immune escape properties from the vaccine. Or a natural landscape that is outstanding like other species The results of this study found that BA.2.75 It is remarkable for its ability to bind to receptor proteins. “ACE2” better on the cell surface BA.2 up to 9 times, which explains that Escaping the landscape may not have to be very skilled. but binds well to cells can become a main strain of the virus
Keep an eye on “BN.1”, catches ACE2 as well as BA.2.75, but is better at fleeing Phum!
Therefore, using the ability to escape landscape alone It may not be enough to predict the direction of the virus to adjust itself. A virus that will become the main species in nature. thus trying to strike a balance between the ability to bind to the receptor protein. and the ability to escape the landscape to a reasonable level Which one is in the perfect position is probably the most suitable one in nature. which if you look at the graph that compares both the landscape escape and ability to bind to proteins ACE2 Now, the most interesting thing right now is the group. “BN.1” because caught with ACE2 have the same level as BA.2.75 But fleeing the landscape is significantly better.
Alleviate doubts regarding booster vaccine booster After COVID came back to spread once more
Due to the epidemic situation that is not easily resolved and gradually Lam came back once more questions regarding vaccination It is therefore a question that has received a lot of attention. Should the trigger needle be injected or not? when to inject And which group deserves to be injected?
latest Prof. Dr. Yong Phuwarawan, Head of the Center of Excellence in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Stating that COVID, the most frequently asked question is regarding vaccination once morest COVID. After 3 doses, 4 doses or 5 doses of vaccination, will I need another vaccination?
The word vaccination Count the total number of needles injected. no matter what kind of vaccine Even if it’s a Chinese killed vaccine, it’s also counted. All vaccines injected are no different. can be cross type Therefore, I would like everyone to receive at least 3 doses of the vaccine, and when it has been given for more than 4 months, I will give 4 doses, it doesn’t matter.
Is the 5-needle COVID vaccine necessary? – Who should inject it?
In the case that has received 4 injections, the next injection will be given, please consider if the body is healthy and normal, and the age is less than 60 years old, there is no need to give more. even if infected The severity of the disease is very low. Which will continue to give in the 5th needle, we will take into account the following.
- 1. In people with fragile bodies and very weak very elderly, chronic diseases such as chronic kidney failure, cancer, lung and heart disease including encephalopathy bedridden patient should continue to be vaccinated If the fourth dose of vaccination has been given for more than 6 months, the next dose can be boosted.
- 2. The 5th dose of vaccination, please consider our physical condition. If we are strong, it’s not necessary. But if the body is very weak. as mentioned It should be encouraged.
- 3. In the event that 3-4 doses of the vaccine have been received or more and infection occurs Infection is considered 1 more vaccination naturally. Therefore, those who are already infected The resulting immunity is a highly efficient hybrid immunity.
infected person Will there be another vaccination? You should do the following:
- 1. If you have never been vaccinated before and are infected, it is advisable to continue vaccinating. The first dose is regarding 2-3 months away from the infection and then injecting the second dose 6-12 months away from the infection will have complete immunity.
- 2. If vaccination has been given 1 dose and then infected The next vaccination approximately 3 to 6 months following infection is considered 3 doses (infection is considered 1 spontaneous vaccination). The next injection should be at least another 4-6 months apart, in principle, the farther the better.
- 3. In the event that 3-4 doses of the vaccine have been received or more and infection occurs Infection is considered 1 more vaccination naturally. Therefore, those who are already infected The resulting immunity is a highly efficient hybrid immunity.
Doubts regarding wearing “Hygienic mask”, doctors worried regarding the disposal of waste from masks
Prof.Dr. Yong Poovorawan Indicates wearing a hygienic mask that There is a question that How long will we wear a hygienic mask? Let’s help each other decide for themselves in normal times. Face masks are intended for patients with respiratory diseases to wear. to prevent the spread of the disease Normal people don’t need to wear it. Everyone has to be responsible. If you know you’re sick, you should wear it. and discipline
Wearing a hygienic mask to prevent COVID-19 If not properly put or not taking care of hygiene The effectiveness of defense will be greatly reduced. There are studies to support clearly, for example, wearing incorrectly Handling a surgical mask following wearing it without washing your hands It has been studied that many face masks are captured each hour. This greatly reduces efficiency due to contamination.
by interesting study printing house in the journal PNAS A study of people who wore masks and those who did not wear masks competed in chess. It will be found that wearing a hygienic mask will affect the mind. (cognitive) in the early stages of the competition and if you wear it for a long time there will be an adjustment Face masks may have a high level of cognitive effect. But in normal conditions, I wouldn’t see any difference.
in young children, especially kindergarten children Learning whether it’s a language There will be both spoken languages (verbal) and body language (non verbal) such as observing from the lips Therefore, in young children It’s difficult to put on a mask properly. And it also affects learning for children.
Therefore, there is an opinion that in the classes of young children Wearing a face mask will hinder learning. And the practice of children in caring for masks is difficult to be effective. The need to wear a hygienic mask is less. in the condition that the severity of the disease is reduced Children also learn from teachers.
In addition, another important issue is the disposal of surgical mask waste. because the use of a large number of surgical masks that are synthetic surgical masks will cause micro plastic increase in the environment At the moment, if you are in an open area such as the seaside, park, there is no need to wear a mask. I hope following February Most of them have immunity from vaccination. or already infected The disease will be reduced and more adaptable The need to wear a mask will be less. It is worn when in a large group of people, such as in a bus, plane, train, and the person who must wear it is likely to be among the patients. or people with respiratory disease symptoms
