“Mo Yong” took off lessons for 3 years. Covids are re-infected. It can be once more. Thailand will encounter outbreaks twice a year when most people are infected. hybrid immunity There will be no need for frequent vaccination.
COVID-19 today (12 Dec. ’22), Prof. Dr. Yong Phuwarawan, head of the center specialized in clinical virology. Department of Pediatrics Faculty of Medicine Chulalongkorn University Disclosed via personal Facebook In one message stating that From the past 3 years, we have learned regarding COVID-19 and changing understanding more as follows
1 COVID 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 in the early stages. in hopes of halting the spread of the disease It doesn’t apply to COVID-19, although almost all people are immune to it. The disease is still the same. not gone anywhere
3 COVID-19 is a seasonal disease. For Thailand, there will be a peak of the outbreak in June to September and the second period in mid-November to February, but less than in the first period.
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 currently in use 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 Vaccine Immunity 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 mortality 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 important things that will continue to focus on treatment in vulnerable groups 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 the majority 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 Populations that have no 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 the mother. 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 All 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
