“Dr. Thira” points out that China has opened up the country, do not drop cards, pointing out that Omicron is very easy to get stuck.
On January 8, Dr. Thira Woratanarat, Department of Preventive and Social Medicine Chulalongkorn University Faculty of Medicine 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, for a total of 668,193,917 people and a total of 6,710,616 deaths: the top 5 infected are Japan, South Korea, Taiwan, Hong Kong and China.
As of yesterday, in the number of new infections, countries in Europe and Asia occupied eight of the top 10 and 17 of the top 20 globally. The number of new infections per day worldwide at this time from Asia and Europe together accounted for 97.05% of the world, while the number of deaths accounted for 94.01%.
…Omicron subspecies COVID-19 update
The latest data from Github as of January 5, 2023 reflects that several emerging subspecies have higher epidemic expansion rates than their predecessors. The ones that caught the eye were XBB.1.5, BQ.1.x, BA.2.75.x, CH.1.1, etc. Outbreaks of various subspecies have occurred on all continents. The proportions vary.
In this regard, Gerstung M of Heidelberg University Germany XBB.1.5 is estimated to be despite the epidemic expansion rate faster than others. But the overall fitness of the virus is equal to BQ.1.1.
…if that’s as personally assessed as I expected This year’s global outbreak Seems to continue as a variant of 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 in daily life Including vaccination coverage and conditions for receiving it.
…Why is Omicron so contagious?
Wu CT and others of 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 on the cell surface by entering through mobile cilia on the upper respiratory tract mucosa.
Within 24 hours of cell infection, there is a process of stimulating the microvilli to multiply rapidly. To help spread the infection across the surface of the respiratory mucosa with secretions such as mucus so that it can spread the infection to others.
The team also demonstrated 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 in the last year.
…The situation in Thailand
Again, it is necessary to protect yourself regularly, not to let your guard down, not to fall into a lie with superstition. that pushes them to get rid of the mask Whether they are adults or children Why 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 leak over the past two years and what happened. and why
wearing a mask correctly during your daily life outside the home, including work, study and travel It will greatly reduce the risk of preventing infection. Or don’t reapply, that’s best. After being blocked, it will not finish. Relax and recover. But severe disease, death, and long-term risk of COVID.
