Doctor Thira has updated the subspecies of “BA.2” Omikron faster than Delta?

Today (26 Jan. 65) Assoc. Prof. Dr. Teera Woratanarat Faculty of Medicine Chulalongkorn University Post a comment about the COVID situation. via Facebook Thira Woratanarat

by stating that “January 26, 2022 has exceeded 358 million

Yesterday around the world, 3,001,336 people were infected with 8,416 more deaths, a total of 358,670,890 people infected with 5,631,996 deaths.

The top five with the most infections were France, USA, India, Italy and Brazil.

The number of new infections every day in the world now. from Asia, Europe and North America which together accounted for 86.72% of the world’s population, while the number of deaths accounted for 82.8%.

Recently, the number of new infections from Europe accounted for 53.31 percent of the world, while the number of deaths rose to 43.13 percent.

Yesterday, the number of new infections was five of the top 10 countries from Europe and 12 of the world’s top 20.

…Update 2 interesting things

1. Omicron subspecies BA.2

Data from Prof. Moritz Gerstung from the German Cancer Research Center shows that the daily number of new infections in Germany is BA.2 more than Delta (5% vs 2-3%) when comparing the rate of spread of outbreaks for each species. will find Omicron BA.1 (first strain) is about 15% faster than Delta, but Omicron BA.2 strain This is about 20% faster than Delta. Berlin is now the city with the most BA.2, accounting for 30% of BA.2.

2. The incidence of myocardial infarction from mRNA vaccines

Oster ME et al published a follow-up study after mRNA vaccination (Pfizer/Biontech: BNT162b2 and Moderna mRNA-1273) in the journal JAMA International Medical Journal on January 25, 2022. From December 2020 to August 2021, the number of people who received Vaccinated over 12 years of age 192,405,448 people received 354,100,845 doses of vaccine.

A number of adverse reactions have been reported in people. A total of 1,626 people had myocarditis.

the rate of myocardial infarction It was most common between the ages of 12-15 years (70.7 cases per 1 million doses of BNT162b2 injection).

It was highest in adolescent males aged 16-17 (105.9 per 1 million doses of BNT162b2) and in males aged 18-24 years (52.4 cases per 1 million doses of BNT162b2 and 56.3 cases per injection. mRNA-1273 (1 million doses)

Most of myocardial infarction patients receive treatment until they recover. often using anti-inflammatory drugs (Nonsteroidal anti-inflammatory drugs: NSAIDS)

However, it is well known that The benefits of vaccination far outweigh the risks. because if infected with COVID-19 There will be a risk of illness and death. including more complications
