On January 8, 2023 Assoc. Prof. Dr. Thira Worathanarat or “Doctor Thira“Faculty of Medicine Chulalongkorn University Facebook post regarding the issue “COVID-19” indicates that
yesterdaycovid around the worldAdded 373,639 people, 802 more deaths, total 668,193,917 people. DiedTotal 6,710,616 people
The top 5 most infected with COVID-19 are:
- Japan
- South Korea
- Taiwan
- Hong Kong
- China
As of yesterday, in the number of new infections, countries from Europe and Asia occupied eight of the top 10 and 17 of the top 20 globally.
The number of new infections per day around the world right now from Asia and Europe Together, it accounted for 97.05 percent of the world, while the number of deaths accounted for 94.01 percent.
COVID-19 Update subspecies of Omicron
The latest data from Github up to January 5, 2023 reflects that.subspeciesEmerging variety that has a higher rate of expansion of the outbreak than the original species that had spread before
The one that is being watched is inevitable. XBB.1.5, BQ.1.x, BA.2.75.x, CH.1.1 and so on. Across every continent, there are outbreaks by various subspecies. Proportions vary.
In this regard, Gerstung M from Heidelberg University Germany Estimated that XBB.1.5 is despite the rate of expansion of the outbreak faster than others. But overall, viral fitness is as good as BQ.1.1
If it is as assessed I personally expected This year’s global epidemic Probably in the form of a cup of soup species (variant soup) and so on. There are many subspecies that have different influences in each region. It depends on the proportion of infected subspecies present in that area. Self-defense during daily life Including the coverage of vaccination and the conditions of receiving it.
Why is Omicron so infectious?
Wu CT et al. from Stanford University. United States The results of the study were published in the journal Medical Sciences Cell on January 5, 2023, showing that COVID-19 virus can be infected It binds to the ACE2 receptor at the cell surface by entering through the motile cilia on the upper respiratory tract mucosa.
Within 24 hours of infecting the cells, there is a process of stimulating the microvilli to rapidly multiply. To help spread the infection through the surface of the respiratory mucosa with secretions such as mucus so that it can spread the infection to others.
The research team also proved that the species Omicron It infects the airway epithelial cells more frequently than any other strains previously seen in the outbreak, Delta and D614G.
We are therefore not surprised that Omicron has caused an explosion of infections over the past year.
Thailand’s COVID-19 situation
Once once more, it is necessary to protect yourself regularly, do not drop your guards, do not fall into lies with superstition. that urges to discard the mask Whether adults or children Because when there is a problem The people who will face this crisis are you and your family. Not a fake news source Please remember the lessons of the losses over the past two years as well as what happened. and why
wearing a mask correctly during daily life outside the home, including working, studying and traveling It will greatly reduce the risk.
protect yourself from infection Or don’t repeat, it’s the best.
Addicted and not finished, just chilling and recovering, but severe illness, death and risk of further Long COVID long term
