Dr. Yong Phuwarawan, Head of the Center of Excellence in Clinical Virology Faculty of Medicine Chulalongkorn University Post a message via personal Facebook stating that the outbreak of COVID is seasonal. in the rainy season as previously expected The epidemic will continue until July-August. and will begin to decrease in Sept.
for the currently found species Almost all of them were XBB strains, with Duangkaew strain XBB.1.16 being the dominant strain. From the study data, it was found that immunity from past vaccines that started from the Wuhan species and adding the BA.5 strain to the two vaccine strains immunity that arises It cannot prevent infection with the XBB strain.
in terms of recurrent infections In a study of 250 people, it was found that the second severity was much less than the first. Getting infected a third time is not uncommon. just like the flu When the species changes It can be new again, however, the primary immunity is enough to help protect and reduce the violence. but does not prevent infection
The future of vaccination There has to be some flu-like foresight. that the species that will spread will change in any direction, such as the World Health Organization Advise vaccine companies to produce vaccines that are strain XBB, but in the manufacturing process It takes at least 6 months because at that time The virus will change the species again.
However, from studying the mutation rate If compared to the early stages of COVID-19 The mutation rate is very fast and high. But until the past year Slower mutation rates range from 1.2 to 6.7 vacancies per thousand per year. This virus has a total of 30,000 positions. Looking at this rate, is similar to influenza A, so the tendency of this virus would be close to influenza A in the future, that is, if infected with a different strain have another chance
