Facebook Opass Putcharoen of Prof. Dr. Opas Phutcharoen posted on the issue of “new strain of covid“Indicated that the season of BA.4 and BA.5 This year, the whole year there will be a parade of descendants of “Omikron“The epidemic is rippled. The virus will pick up people who haven’t been infected. Because the virus will be changed to become infected more easily than before. People will cycle through infection both in those who have been vaccinated and re-infected in people who have been previously infected. The data of people who have re-infected from Europe are at 0.7 – 0.9%, but the number is actually much better. Recurrent infections are asymptomatic.
Worldwide, the proportion of BA.4 and BA.5 Increase is replacing the original species. It is probably a common strain that has caused a small new wave of outbreaks in many countries. After this, there will be offspring.”Omikron“With a small epidemic, we still can’t build a barrier against infection. but resistant to severe disease from the vaccine which at least getting a booster needle will help

In South Africa it appears to be less severe than the BA.2 Omikron, but some European countries say it is as violent as the “Omicron”. with omikron Look at the rate of hospitalization, pneumonia, mortality.
The data in the lab looks harsh, but in humans it may not always be the case. Still not very shocking Because in people, the violence will be greatly reduced if there is still immunity from the vaccine.
As for the hospital now, the outpatients are getting tight again. The inpatient bed will come back tighter. But the intensive care of each hospital depends on the booster vaccination in each location.
The economy still has to move on and get used to the long-lived virus. What is important is immunity, vaccines, antiviral drugs for people at risk of death.
