19 July 2022…
Yesterday, the world infected with 401,359 people, 909 more deaths, totaling 568,111,043 people with 6,388,680 deaths. The top 5 infected people are Japan, Australia, Brazil, Italy and the United States.
Yesterday, the number of new infections, countries from Europe and Asia occupy 6 of the top 10 and 14 of the world’s top 20. The number of new infections every day of the world now. from Asia and Europe Together they accounted for 66.23% of the world’s population, while the number of deaths accounted for 54.67%.
…the epidemic situation of Thailand
From the Worldometer data this morning, it was found that
Number of deaths yesterday It is the 10th highest in the world and 2nd in Asia, although the Thai Ministry of Health has adjusted the reporting system from May 1 until the number of reports is greatly reduced.
…An interesting update
Three doses of Novavax have the same level of intravenous immunity against Omicron virus as the three doses of the mRNA vaccine (BNT162b2). Bhiman JN and researchers from South Africa published the results of a study in bioRxiv on 17 July 2022. Covid-19 Omicron subspecies BA.2.75
Originally found for the first time in India. and spread to many countries with data from research In conclusion, as mentioned a few days ago, a research team from the Indian SARS-CoV-2 Genomics Consortium (INSACOG) provided information via local media (Times of India, 4 July 2022) that the Omicron subspecies detected In India, that is a concern.
Both BA.2.74, BA.2.75, and BA.2.76 were initially assessed to be more likely to have viral fitness than BA.5 Yamasoba D and Japanese researchers. Results published in bioRxiv July 15, 2022. The study found that BA.2.75 was characterized by resistance to several therapeutic antibodies. Just like the subspecies of Omicron that had preceded the epidemic. But some antibody drugs can still be effective in managing infection, such as Regdanvimab, Sotrovimab, Tixagevimab.
while Cao YR from Peking University Publish Informal Laboratory Study Results indicated that BA.2.75 was more likely to bind to the ACE2 receptor than BA.4 and BA.5.
But in terms of immune resistance A study by looking at immunity from people who have been vaccinated and infected with COVID-19 found that BA.2.75 is more resistant than BA.2.12.1, but may be less than BA.4 and BA.5, except in the case of people who have been infected with the strain. Delta preexisting BA.2.75 is more resistant than those infected with Omicron BA.1 and BA.2 strains.
However, it will have to wait for the official results of the study. and from other research in the near future To confirm the immune resistance characteristics of BA.2.75
Recently, Rajnarayanan R from Arkansas State University has reported an update on the detection of the BA.2.75 subspecies that has caught the attention of the world. interesting is It was reported to have been found in Thailand from specimens from Trang Province. Since June 28, 2022 … the epidemic situation in Thailand is still ongoing.
A recent report today, 18 July 2022 by the European Center for Disease Prevention and Control (ECDC) indicates that Omicron BA.4 and BA.5 in Europe are experiencing a serious outbreak.
and made the number of patients requiring hospitalization at all ages
In addition, the patient was so severe that he was admitted to the ICU and on a ventilator. markedly increased in people aged 40 and over
…Thai, we must be careful. Because the nature of disease is often consistent wherever in the world it is. And there is a high chance that we will be dealing with outbreaks with different subspecies. can go together If not protected
From the knowledge I have now, BA.4, BA.5 and BA.2.75 are not shoddy.
able to live, earn a living, study But you should always protect yourself. no matter what species If we live consciously Using the right knowledge and not being careless will greatly reduce the risk.
Vaccination with booster needles is necessary.
And what is absolutely necessary is… wearing the mask properly is very important…
