It has been more than two years since the New Coronavirus outbreak in 2020, but due to the RNA genetic material of New Coronavirus, it has been evolving and mutating since its discovery, so the epidemic has been coming and going, including mutated strains such as Alpha, Beta, Delta, and Omicron strains.
These two new strains were first discovered in South Africa in January of this year. These two new mutant strains were first discovered in South Africa in January this year and have spread to more than 20 countries worldwide in just a few months. Although the dominant mutant strain in the world is still the Omicron variant BA.2, other mutant strains should not be ignored. In March this year, the WHO added BA.4/BA.5 to the surveillance list.
According to the latest scientific studies, the Omicron variant BA.4/BA.5 is more immune escape than the other variants, more likely to evade previous infections and antibodies produced after vaccination against Neocrown, and therefore has a greater transmission and re-infection capacity.
The latest WHO weekly epidemiological progress of Neocrown shows that the prevalence of BA.2.12.1, BA.5 and BA.4 variants is increasing globally, with BA.5 variants now found in more than 40 countries and BA.4 variants in more than 40 countries. Currently, the European Center for Disease Control and Prevention (ECDC) has upgraded it to the highest level of alert.
On May 28, the Chinese Center for Disease Control and Prevention (CDC) reported the first imported case of BA.5 variant of New Coronavirus Omiqron infected outside China, which is also a wake up call that new variant strains are coming.
New coronaviruses are RNA viruses with extreme mutation capabilities that will likely continue to evolve under immune and selective pressure, leading to immune escape. Many infectious disease experts believe that BA.4 and BA.5 may cause more new cases in the future than BA.2.12.1, or become the new mainstream strain worldwide.
In the face of these two mutated strains, we not only need to accelerate the process of vaccine development, but also need to monitor their possible immune escape strains in a timely manner and take active measures to prevent and control them from causing new outbreaks to spread.
Currently, the New Crown Nucleic Acid Rapid Test is covering ORF1ab as well as N gene targets, which can effectively avoid the risk of off-target and missed detection when detecting the new mutant strain BA.4/BA.5 of Omicron. The New Crown Nucleic Acid Rapid Test System is equipped with a portable amplification instrument and highly efficient amplification reagents, which greatly shortens the amplification time and can complete amplification in about 30 minutes, shortening the New Crown Nucleic Acid Rapid Test time to within 1 hour. Effectively bringing forward the gateway to the discovery of exotic mutant strains!
