Next is another species. Omicron strain BA.2.2 This one, discovered in March 2022 in Hong Kong, was caused by a mutation of the original omikron that was severely prevalent in Hong Kong until it developed into a new species. It is a breed that many people worry about. because the death toll in Hong Kong has increased until the highest record in the world
However, from the BA.2.2 strain found in Thailand, there were no severe symptoms. and found no more deaths than other species Also, the transmission is not faster than other strains as well. There is also no data that reduces the efficacy of the vaccine. or avoiding more vaccines than other omikron strains The reason why the BA.2.2 strain in Thailand is not as severe as in Hong Kong This is because there are strains BA.1 and BA.2 that have already occupied the epidemic area.
The species that many people have heard of recently is the Omicron strain XE which on March 31 past the World Health Organization has issued a warning about the new Omicron hybrid XE, a cross between BA.1+BA.2 omikron, that it may be coronavirus. that spreads the fastest It was first seen in the UK. As of January 2022, more than 600 people have been infected, while Hong Kong has confirmed two cases of Omikron XE and one in Thailand.
and what to watch out for is Omicron species XE Develops infectivity up to 10% faster than BA.2 strains and spreads faster.The original omikron (BA.1) to 43%, it will take time to prove that the “XE” hybrids will become the new wave of the global epidemic. And can it replace BA.2 or not?
Omicron, strain XJ In addition to the XE species, there are nowOmicron species XJ which isA hybrid of the Omicron subspecies BA.1 and BA.2. which was first found in Finland And found one infected in Thailand. The highlight is the ability to evade immunity. The ability to spread The severity of symptoms in the XJ strain as viewed from the genetic code on the genome. Many experts agree that it should not be different fromOmicron BA.1 strain and BA.2
– What are the symptoms of covid omicron?
for All 5 strains of covid omicronThese findings generally have the same symptoms. Unless the ability to spread rapidly varies. From the data collection of the Thai Ministry of Public Health, it was found that in 100 people, if infected with covid omikron will show the following symptoms
54% had a cough
37% had a sore throat
29% had a fever
15% had muscle pain
12% had a runny nose
10% had a headache
5% had difficulty breathing
2% had a decreased sense of smell
But even if the symptoms in the first infection are not severe. But they can develop more severe symptoms. especially those in the risk group have a congenital disease Therefore, it should not be complacent. Still have to be careful to prevent the risk of contracting COVID. is to wear a mask every time when in a crowded place or a large number of people Because omikron is easy to infect. Try to avoid sharing meals. and distance
However, most of the people who died from COVID Omicron infection were those who had not been vaccinated. Therefore, vaccination against COVID is still necessary and extremely important. Although it does not help prevent infection But it can significantly reduce the severity of the disease better.
