“Mo Yong” reveals 15 things learned from “Covid” over the past 3 years, pointing out that it can be once more. Immunity doesn’t stop the outbreak. The disease has not yet disappeared. Next, it will be a seasonal disease in Thailand, which is during June-September and November-February without a vaccine. Everyone is different. life will become normal until becoming a respiratory disease from a virus The severity is reduced like influenza and RSV.
On December 12, Prof. Dr. Yong Phuwarawan, Head of the Center of Excellence in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Revealed through Facebook Yong Poovorawan up to 15 lessons learned regarding COVID-19 in the past 3 years that 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 recurrent disease occur Like influenza, RSV, unlike measles, hepatitis A, and chickenpox, once infected has lifelong immunity once morest disease.
2. Herd immunity, which has been talked regarding a lot in the early stages in the hope of ending the outbreak, is not applicable to COVID. 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 when used in practice 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. Will be a group of small children from birth to until vaccination 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
