Prof. Dr. Opas Phutcharoen Head of the Emerging Clinical Center Chulalongkorn Hospital, the Thai Red Cross Society, has posted on his personal Facebook page, Opass Putcharoen, stating: covid 19 the direction of the epidemic BA.4-BA.5 including the likelihood of re-infection By stating that … the season of BA.4-BA.5 This year, the whole year there will be a parade of children of Omicron epidemic in waves. 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 had re-infected from Europe is 0.7-0.9%, but the number is actually much higher. Recurrent infections are asymptomatic.
Worldwide, an increasing proportion of BA.4 – BA.5 are replacing the original strain. It is probably a common strain that has caused a small new wave of outbreaks in many countries. After this, there would be a small ripple of omikron descendants. 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
