respiratory disease Whether it’s the RSV flu, COVID 19, the virus has changed strains all the time as well. to escape the original immunity and can cause new infections But if the body is healthy, the severity will be less or no symptoms.
Taking care of the body to be healthy, hygiene, prevent infection and reduce the spread of disease. Including prophylactic vaccination in risky and vulnerable groups is therefore a method to reduce the loss of such diseases. But at the same time, RSV does not yet have a vaccine to prevent it despite decades of development efforts.
However, earlier, Mo Yong posted a Facebook post stating that on May 2, 2023, COVID-19 has adapted to a seasonal disease. And for Thailand, the epidemic will start when entering the rainy season. especially during the first semester of students And this year, together with the election campaign There is a large gathering of people Great chance to spread The disease is more common at the end of this month following the election and the students have opened the semester
Most of the strains currently found are XBB, especially XBB.1.5, which has replaced the endemic strain BA.2.75 since the beginning of the year, but all of them are descendants of Omikron. Which species are more likely to be infected? Better at avoiding immunity, it will take its place. The star species XBB.1.16 is still very rare.
All species are now distributed worldwide. The severity of the disease was greatly reduced compared to the original strain (more than 90%). The majority of severe cases or deaths were in the vulnerable group. Risk group or what we call 608
Currently available vaccines, although they do not protect once morest infection. but can reduce the severity of the disease Therefore, vulnerable risk groups should be vaccinated. and to be regarded as a seasonal vaccine that must be injected before the rainy season, which is in this month as well as the flu vaccine which can be given at the same time by injecting at different positions or on different arms
Currently used vaccines, if it is mRNA, the vaccine will be 2 types, bivalent, that is, the original strain, Wuhan, combined with Omikron that is used in our country, if it is Pfizer, it will be BA.1, and Moderna will be. Moderna’s BA.5 contains half the amount of RNA (50 mcg) of the single strain vaccine we used in the past (100 mcg).
In healthy individuals under 60 years of age, vaccination is voluntary. because the severity of the disease is less than the risk group 608
Finally, in the near term, I believe The World Health Organization would likely stop counting the number of people infected. because the numbers reported to the World Health Organization much lower than reality Including Thailand has not counted the number of infected people. Only those who are admitted to the hospital are counted. and the deceased The number of infected people is dozens of times higher than the number hospitalized.
In addition, Moyong also answered questions from news fans, “COVID-19, should I be vaccinated or not? Is a frequent question”Refer to the post on April 23, 2023 that
The COVID-19 situation is constantly changing. Now entering the 4th year, the severity of the disease is high. Therefore, it is classified as a serious contagious disease. We scramble to find out if the vaccine Later, when the severity of the disease decreased in the next 2 years, it became a contagious disease that must be monitored. And nowadays, COVID 19 has turned into a seasonal disease.
Vaccination is adjusted to seasonal disease vaccination. will be given before the season of the disease And will be adjusted once a year, just like influenza The season of the disease that will have more outbreaks. In each country will not be the same. For example, in the Northern Hemisphere and the Southern Hemisphere where there is a cold season, the outbreak will occur in the winter.
Thailand is in the tropical zone. Although above the equator However, there is no true winter, very hot and less hot, so disease outbreaks in Thailand can be found throughout the year. But it is found to be highest in the beginning of the rainy season. or the first semester of students
Like influenza, vaccines do not protect once morest infection.
but can reduce the severity of the disease Vaccination therefore focuses on risk groups. Vulnerable Groups 608 People in densely populated areas such as prisons, military facilities and medical personnel who are prone to infection. It should be given seasonally once a year.
The right time for vaccination in Thailand It is prior to the outbreak that will occur in May to June onwards. Therefore, the appropriate time for annual vaccination is at the end of April, May of every year.
Therefore, those who have been vaccinated for more than 3-6 months and are in the risk group Seasonal vaccination should be given once a year. This year, it can be started before the outbreak of the disease. using the closest species available Then give it 1 more time next year, everything will be similar to the flu.
In normal people, it is voluntary, just like influenza. But those who will benefit the most are the vulnerable groups as mentioned above. to reduce the severity of the disease
Referring to this series of articles, dated December 12, 2022, Dr. Yong or Prof. Yong Phuwarawan, M.D., head of the Center of Excellence in Clinical Virology. Department of Pediatrics Faculty of Medicine Chulalongkorn University Post a message via Facebook that
Covid 19 Lessons learned from the past 3 years (Latest, today we step into the 4th year of COVID)
Bring it to serve for Nation online news people to read back and review all bad memories. not memorable About the villain COVID-19 Covid Omicron that killed many people
From the past 3 years, we have learned regarding COVID-19 and changing understanding more as follows
1. COVID-19 disease, it can be once more. recurrent infection Or symptoms of the disease can occur repeatedly, like influenza RSV, unlike measles, hepatitis A, chickenpox, which once infected will have lifelong immunity once morest disease.
2. Herd Immunity was talked regarding a lot in the early stages in hopes of ending the epidemic. Not compatible with covid-19, although almost all people are immune. The disease is still the same. not gone anywhere
3. COVID-19 is a seasonal disease. For Thailand, there will be the peak of the outbreak in June to September and the second period in mid-November. until February but less than in the beginning
4. The hope of using vaccines to end the epidemic or control the outbreak as expected in the first year therefore cannot be used
5. Vaccines that are currently used No vaccine is a god vaccine. As everyone initially demanded Every vaccine is different. only reduce the severity of the disease reduce the death rate
6. Immunity arising from vaccines whether high or low measured unable to prevent infection There is no need to measure immunity. Except in research studies only.
7. Critical care must focus on risk groups to reduce the death rate. Whether preventing death with vaccines Next, we need to focus on vulnerable groups like influenza.
8. Diagnosis of infection or not At present, only ATK is sufficient, although its sensitivity is lower than realtime RT -PCR due to cost and duration limitations. We’ve run out of a lot of money.
9. The next important thing is to focus on treatment in the vulnerable group. especially the use of antiviral drugs powerful And it’s going to be better nowadays. Most studies in small populations work well. But when it was actually used, it was less effective than the study. The same goes for vaccines. The experiment works well, but in practice it is much less effective than the experiment.
10. Quarantine period always less The first phase must be strict regarding spreading to zero. But nowadays, the disease is easily contagious. Strict measures and discipline were therefore applied. home quarantine It’s not a hospital or a field hospital anymore. The hospital will treat patients with severe symptoms only. as in normal
11. In the future when most of the population is infected It will form a hybrid immunity. It is effective in reducing the severity of the disease as well. frequent vaccination will not be necessary The virus itself changes genetically over time. The resulting immunity cannot prevent infection.
12. Population groups that do not have immunity or have never been infected and have never been vaccinated. It will be a group of young children from birth until they receive the vaccine or infection. However, childhood infections Less violence in adults or the elderly In the first 6 months of childhood, some of the landscapes are passed down from their mothers. Like common respiratory diseases such as RSV and will start to become infected following 6 months.
13. Next period Life will become more and more normal. And this disease is a respiratory disease. The same is true for other respiratory diseases caused by viruses.
14. Every life must move on. and believe that The severity of the disease tends to decrease as with respiratory diseases such as RSV influenza.
15. New knowledge through research There is still a need for continuing education. to use that knowledge in the context of Thailand
