“Mor Manoon” keeps an eye on the XBB.1.5 outbreak in Thailand, revealing people who are not infected with COVID will be this round
On January 26, Dr. Manoon Leechawengwong, head of respiratory disease Vichaiyut Hospital Has posted on Facebook named “Mr. Manoon Leechawengwong FC”, stating that “At this time, the epidemic of the COVID virus in Thailand is in a downward trend. The number of infected and seriously ill people has decreased significantly. believe that it will soon be back up again Because the new COVID virus, the XBB.1.5 strain, will sooner or later enter Thailand from people traveling from western countries.
The COVID subspecies XBB.1.5 evolved from XBB, which was first identified in India in August 2022. XBB is a hybrid of the COVID-19 strains BA.2.10.1 and BA.2.75.
XBB has a mutation that allows it to overcome the body’s immunity. and the XBB.1.5 substrain had a mutation in the F486P spiny protein, which showed enhanced cell adhesion ability. This makes it 5 times more invasive than other omikron strains. XBB.1.5 is now the No. 1 in the United States, replacing BQ.1.1 and BQ.1 strains.
The COVID virus that is currently spreading in Thailand is the BA.2.75 strain, not yet XBB.1.5. Thai people do not need to be afraid of the XBB.1.5 strain. Does not make people more ill than other Omicron strains. XBB.1.5 are very easy to stick together. People who have never been infected with COVID It will eventually infect this new strain. In addition, people who have received a full dose of vaccine and a booster, or who have been infected, can still get this infection because XBB.1.5 is better at avoiding immunity than other strains. But most people, if they receive the booster vaccine or have been infected before, will not get very sick. Immune evasion may render Evusheld immunotherapy ineffective, but the antiretroviral drugs remdesivir, paxlovid, and molnupiravir still work.
