surpassed 481 million
Yesterday around the world, the number of people infected increased to 989,476, with 2,324 additional deaths, bringing the total number of infections to 481,859,155 people, with a total of 6,147,878 deaths.
The top five with the most infections were South Korea, France, Vietnam, Germany and Italy.
Yesterday, the number of new infections included countries from Europe and Asia in nine of the top 10 and 15 of the world’s top 20.
The number of new infections every day in the world now. from Asia and Europe together accounted for 90.85% of the world’s population, while the number of deaths accounted for 82.22%.
New infections in Asia accounted for 56.48% of the world’s population, while the number of deaths rose to 47.46 percent.
…The epidemic situation of Thailand
Yesterday, the number of new infections, including ATK, was the 6th highest in the world and 3rd in Asia.
While the number of deaths yesterday 10th highest in the world
…Update research on BA.2 species
Lentini A et al. published the results of the Swedish study in medRxiv yesterday, March 27, 2022.
It was found that people infected with Omicron strain BA.2 have viral loads in the throat. 2 times more than the original strain BA.1
That is evidence explaining the phenomenon that many countries around the world are facing a re-emergence of Omicron BA.2, which is now the main strain.
The higher the number of viruses The greater the chance of spreading. The results of this Swedish study suggest the amount of virus in the throat. which is the upper respiratory tract therefore having the opportunity to infect others easily whether from meeting, talking, mingling closely or share food and utensils used for eating and drinking including cigarettes and others
Meanwhile, the UK HSA has released a summary of the current knowledge of the BA.2 strain as follows:
One, binds to the ACE2 receptor on the cell surface better than BA.1, which should be reason enough to explain its greater infective capacity.
Second, the secondary attack rate is higher than BA.1
Third, the period from the first day the first infected person develops symptoms. to people infected with symptoms (serial interval) shorter than BA.1
Even now the information is available It is likely that BA.2 is as severe as BA.1, but with greater infectivity. The higher the number of cases, the higher the number of morbidity or death.
Regular, routine self-defense is therefore very important.
Our Thai now BA.2 is the main one as well. And the statistics of daily infections and daily deaths have always been ranked in the world rankings.
put on a mask Meet people as needed. Take a short time. Avoid eating, drinking, or sharing food with others. If you are unwell, tell someone close to you. separate from others and stop studying Go for a checkup to get better first.
For people who have been infected before can be re-infected Therefore, you must protect yourself. They should also regularly check their health performance. If something is different from the past should consult a doctor Because there is a chance for Long COVID, which can occur in almost every system of the body.
