Recently, there has been a lot of buzz about the Omicron strain, which has mild symptoms and is equivalent to the "big flu" after infection. Is the epidemic of the Omicron strain no longer a danger to us? Is there no need for further treatment and prevention after infection with the Omicron strain? Is the rapid testing of new crown nucleic acid relaxed?
On March 25, at the State Council's joint prevention and control mechanism conference, Wu Zunyou, chief epidemiologist at the CDC, said that a study comparing the morbidity and mortality rates in the countries concerned between August 2021 and November to January 2022 concluded that the morbidity and mortality rates did decrease during the Omicron epidemic, but the total number of deaths or mortality caused by the epidemic during the same period was The total number of deaths or mortality due to the epidemic during the same period was higher than the number of deaths during the epidemic of the Delta strain. This suggests that the overall harm caused by the Omicron epidemic in a country is not reduced.
It is well established that Omicron is less symptomatic than Delta, but recent studies show that Omicron is perceived to be less symptomatic, but the damage to the respiratory tract is greatly increased, and not only that, Omicron infects human tissue 70 times faster than Delta.
And, according to research studies, the after-effects of infection with omicron involve 200 symptoms in 10 organ systems, including the human brain, heart, lungs and blood vessels. Cough, fatigue, pain, hair loss, occasional insomnia, brain fog, shingles, arthritis, leg numbness, headache, and vascular dysfunction are all possible sequelae of Omicron infection.
Facing Omicron should not be taken lightly, WHO issued a statement: Do not consider New Guan as a big size flu. Rapid nucleic acid testing for Neoguan still cannot be relaxed.
In the face of rapid spread and mild symptoms of Omicron, how can we effectively prevent it and move the prevention and control gates forward? The key is to do a good rapid nucleic acid test for new crowns.
Nucleic acid rapid test is the "gold standard" for the diagnosis of NICs, which can accurately identify various strains of NICs currently prevalent, including but not limited to: beta, alpha, gamma, delta, omicron and other strains. Exponential amplification of specific fragments of viral genes by real-time fluorescent quantitative PCR reaction reports the fluorescence response.
There are two general methods used for the rapid detection of new crown, one is by adding a releasing agent and directly lysing the virus to release nucleic acid; the other is through a conventional process, using high efficiency amplification reagents and a portable amplification instrument during the amplification phase.
Currently, through the new crown virus nucleic acid rapid test, we are able to complete the amplification phase and report the results in about 30 minutes.
Improving the efficiency of the rapid nucleic acid test for neo-crown enables the prevention and control defense line to be moved forward to deal with the Omicron strain, which must not be taken lightly.
