“Dr. Thira” emphasizes that China has opened the country, don’t fall cards, pointing out that Omicron is very easy to get stuck.
On January 8, Dr. Thira Woratanarat, Department of Preventive and Social Medicine Faculty of Medicine Chulalongkorn University Post a message via Facebook, in the case of January 8, 2023, China opens the country, stating that January 8, 2023…opening day for Chinese tourism…
Yesterday, the world added 373,639 people, 802 more deaths, a total of 668,193,917 people, and a total of 6,710,616 deaths. The top 5 most infected are Japan, South Korea, Taiwan, Hong Kong and 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 several emerging subspecies have higher rates of outbreak expansion than their predecessors. The ones that caught the eye were XBB.1.5, BQ.1.x, BA.2.75.x, CH.1.1, etc. Across all continents, there were outbreaks of 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 Fitness of the virus is equal to BQ.1.1.
…if it is as assessed I personally expected This year’s global epidemic It seems to go on as a variant soup and so on, with many subspecies having 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.
shows 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 team also proved that the Omicron strain was more infectious in airway epithelial cells than other previously known strains, Delta and D614G.
We are therefore not surprised that Omicron has caused an explosion of infections over the past year.
…The situation of Thailand
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 loss over the past two years and 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 to prevent infection. Or do not reapply, it’s the best. After being stuck, it won’t end. Just chill and recover. But severe illness, death and risk of long-term Long COVID.
