The global COVID situation is back to haunt you again. and still continue to find outbreaks especially the species “Omicron” The current outbreak has been around for 1 year and has mutated into more than 500 different subspecies, each of which has a different malignant tumor. Currently, Thailand is one of the countries facing a new wave of epidemicsOmicron especially the species “BA.2.75“ which found a greater proportion until it instead became the main breed of the country BA.5 also gone BA.2.75 There is still an indicative lead in the epidemic. This is part of the fact that the number of infected people in the country tends to increase during this period. make people who were previously infected with this strain can get sick again!!!
“BA.2.75” I’m not good at escaping landscape But why is it so good at spreading?
Dr. Anant Chongkaewwatana, virologist Director of the Animal Health Management and Innovation Research Group National Center for Genetic Engineering and Biotechnology (Biotech) Post a message on Facebook. “Anan Jongkaewwattana” He said research has emerged that matches the current situation in Thailand. because I was wondering why BA.2.75 replaced by the main species BA.5 Yes, despite the results of numerous laboratory tests that this strain of the virus does not have vaccine-escape immune properties. Or an exceptional natural landscape like other species The results of this study have revealed this BA.2.75 It is notable 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 require you to be very skilled. but it binds well to cells it can become a main strain of the virus
Keep an eye out for “BN.1”, he takes ACE2 as well as BA.2.75, but he’s better at escaping Phum!
Therefore, using the ability to escape the landscape alone It may not be enough to predict the direction of the virus to adapt. A virus that will become the main species in nature. thus trying to find a balance between the ability to bind to the receptor protein. and the ability to escape the landscape to a reasonable degree. What is in the perfect location is probably best suited in nature. than if you look at the graph that compares both landscape and escape and the ability to bind to proteins Ace2 Now, the most interesting thing right now is the band. “BN.1” because taken with Ace2 have the same level of BA.2.75 But escaping the landscape is significantly better.
Relieve doubts about booster vaccine after COVID is back to spreading again
Due to the epidemic situation not easily resolved and gradually Lam returned again questions about vaccination It is therefore a matter 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?
most recent Prof. Dr. Yong Phuwarawan, Head of Center of Excellence in Clinical Virology Department of Pediatrics Chulalongkorn University School of Medicine Stating that COVID, the most frequently asked question is about vaccination against 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 is a Chinese killed vaccine, it is also counted. All injected vaccines are no different. it can be cross-type. So I would like everyone to get 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 case you have received 4 injections, you will be given the next injection, please consider if your body is healthy and normal and your age is less than 60 years old, you don’t need to give more. even if infected The severity of the disease is very low. Which will continue to give in the 5th Aug, we will take into account the following.
- 1. In very elderly frail and very weak body people, chronic diseases such as chronic renal failure, cancer, lung and heart disease including encephalopathy bedridden patient should continue to be vaccinated If the fourth dose of vaccination has been administered for more than 6 months, the next dose can be increased.
- 2. The 5th dose of vaccination, please consider our physical condition. If we are strong it is not necessary, but if the body is very weak. as mentioned Should be encouraged.
- 3. In case 3-4 doses of vaccine or more have been received and an infection occurs Infection is considered 1 more vaccination of course. 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 vaccination. The first dose is about 2-3 months after infection and then the second dose injection 6-12 months after infection you will have complete immunity.
- 2. If 1 dose was given at vaccination and then infected The next vaccination about 3-6 months after infection is considered 3 doses (infection is considered 1 spontaneous vaccination) The next injection should be at least another 4-6 months, in principle, the further the better.
- 3. In case 3-4 doses of vaccine or more have been received and an infection occurs Infection is considered 1 more vaccination of course. Therefore, those who are already infected The resulting immunity is a highly efficient hybrid immunity.
Doubts about wearing “hygienic mask”, doctors worried about mask waste disposal
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 for patients with respiratory diseases to wear. to prevent the spread of disease Normal people don’t need to wear it. Everyone must 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 on or not taking care of hygiene The effectiveness of the defense will be significantly reduced. There are studies that clearly support, for example, the incorrect use Handling a surgical mask after putting it on without washing your hands It has been studied that many face masks are captured every hour. This greatly reduces efficiency due to contamination.
from an interesting typography study in the newspaper PNAS A study of people who wore masks and those who didn’t 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 race and if you wear it for a long time there will be an adjustment. Masks can have a high level of cognitive effect. But under normal conditions, I wouldn’t see any difference.
in young children, especially kindergarten children Learning if it is one language There will be both languages spoken (verbal) and body language (Not verbal) how to observe from the lips Therefore, in young children It is difficult to wear a mask correctly. And it also affects children’s learning.
Therefore, it is believed that in young children’s classrooms 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 minor. provided that the severity of the disease is reduced. Children also learn from teachers.
Also, another important issue is the disposal of surgical mask waste. because it will cause the wearing of a large number of surgical masks which are synthetic surgical masks micro plastic increase in environment At the moment, if you are in an open area such as the sea, the park, it is not necessary to wear a mask. I hope after 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 wearing it is likely to be among the patients. or people with symptoms of respiratory diseases
