Although there is still no conclusive expert opinion, many netizens have already started to sit up and discuss whether the virus has a very long incubation period. Is the rapid nucleic acid test still useful in the face of the long incubation period of the new crown?
What is the incubation period? According to experts, the time between the infection and the appearance of symptoms is called the incubation period. According to viral gene sequencing, the virus currently prevalent in China is a delta variant strain. Previous research results from the team of Prof. Tang Xiaoping and Li Feng of the City Eight Hospital affiliated to Guangzhou Medical University, together with the team of Prof.
Zhong Nanshan and Prof. Chen Ruchong, members of the Chinese Academy of Engineering, showed that the Delta variant strain has a short incubation period, rapid transmission and high viral load. The median incubation period of Delta virus is only 4.7 days, and it is easier to detect due to the high viral load. Experts have shown that the ultra-long incubation period of delta virus in the current Fujian outbreak is an extreme example and there is still no evidence that the incubation period of delta virus is getting longer.
The presence of such extreme examples cannot be a reason to question the gold standard of the new crown nucleic acid rapid test for epidemic prevention.
In addition to the extreme example of extra-long latency of delta virus, a study has again demonstrated the importance of rapid nucleic acid testing for the new coronavirus. A study in The Lancet Infectious Diseases, a subjournal of The Lancet, claims that infected individuals rarely developed fever but reported increased sneezing symptoms after vaccination compared to those who were not vaccinated. This finding suggests that for people at high risk after vaccination, if they develop sneezing, even if they do not have a fever, they need to go for a rapid New Coronary Nucleic Acid test for the safety of those around them, in case they take the symptoms of breakthrough infection as a common cold.
As we all know, fever has become an important symptom in our current initial screening of patients with neo-crown, and when this symptom is no longer obvious, the efficiency of the neo-crown nucleic acid rapid test becomes even more important.
Several domestic manufacturers of rapid nucleic acid detection reagents have developed, through technical research and development, highly efficient amplification kits for rapid nucleic acid detection of new coronas that have received national certification, and introduced rapid solutions for nucleic acid detection of new coronas that significantly shorten the time required for amplification and improve the efficiency of nucleic acid detection of new coronas.
