Yesterday, around the world, there were 72,232 more infections, 331 more deaths, a total of 680,275,468 people, and a total of 6,802,158 deaths.
The top 5 most infected are Taiwan, Russia, Japan, South Korea and Austria.
As of yesterday, in the number of new infections, countries from Europe and Asia occupied eight of the top 10 and 16 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 92.9 percent of the world, while the number of deaths accounted for 84.89 percent.
…update the strains that have spread around the world
Gerstung M from Germany point out that In the current situation, XBB.1.5 and its relative XBB.1.9.1 are likely to dominate the global outbreak, while the former BQ.1.x and BA.2.x have been on the decline. Continuous (Pictures 1 and 2)
This is in line with the World Health Organization’s previous risk assessment of XBB.1.5 that XBB.1.5 is likely to continue to expand in the coming period.
…The nature of the cellular immune system after infection in previously vaccinated individuals.
Koutsakos M et al from Australia. Answered the question that many people have been wondering for a long time. If we have already been vaccinated Unintentionally infected with COVID-19, how will our cellular immune system react? (Figure 3)
It was previously known that, after infection, the immune system in blood or antibodies is elevated. But after a few months Antibodies will be reduced.
This research suggests that after infection The cellular immune system is rapidly activated by both CD4 and CD8 T-cells. CD4-type cells are activated as early as 1 day after onset of illness. and increased dramatically, reaching a peak within 5 days after onset of illness
CD8, which plays a role in destroying infected cells, is also activated in response, with the number of CD8 produced varying. and has a response time next to CD4.
…Caring for health is important for living in the current situation.
careful not careless
Adjust the environment to be better ventilated than in the past.
wearing a mask correctly It will greatly reduce the risk. Both from COVID-19 and PM2.5
protect yourself from infection or re-infection is the best
