On September 1, the Argentine Ministry of Health informed that a hospital in Turkmen province in the north of the country reported 2 cases of fatal pneumonia of unknown origin, and in a short period of time, the disease has been diagnosed in a total of 9 people, 3 died, and 1 person is being treated in home isolation, the news said that all 3 patients were diagnosed with severe respiratory disease with bilateral pneumonia, and the imaging manifestations were very similar to New Crown pneumonia, after more than 30 kinds of viruses, including New Crown virus After bacterial tests were done for more than 30 viruses, including New Coronavirus, all were negative. The cause of the disease has been ruled out, such as neocon and influenza, and no "human-to-human" transmission has been detected.
Pneumonia is an acute respiratory infection that affects the lungs and is caused by multiple infectious agents, including viruses, bacteria and fungi. It is also the leading cause of death from infection in children worldwide. Among these diseases, SARS, novel coronavirus, and avian influenza are acute respiratory infections with pneumonia as the main clinical manifestation. For such infectious diseases, which are mainly transmitted through saliva and other means, timely detection of suspected cases, early warning and appropriate preventive and control measures are essential to effectively control the outbreak and prevent the spread of pathogens.
In the case of the New Coronary Pneumonia outbreak, for example, timely detection of cases, isolation and other disposal measures to move the epidemic prevention gate forward are important measures to prevent and control the outbreak. Nucleic acid testing can effectively identify patients with NCCV during NCC outbreaks. The nucleic acid test can accurately identify the virus through multiple steps such as "sampling - sample pre-treatment - nucleic acid extraction - nucleic acid amplification - result analysis". As the "gold standard" for the diagnosis of neo-coronavirus patients, the nucleic acid test mainly identifies two specific gene fragments of neo-coronavirus, N gene and ORF1ab gene, which are the hallmarks of neo-coronavirus, so as long as these two gene fragments report fluorescence signal during the test and the Ct value reaches a certain level, the infection can be confirmed. level, then an infected person can be identified.
Similarly, other viruses are tested for nucleic acid detection by specific identification of specific fragments of viral nucleic acid fragments by PCR or RT-PCR.
During the period of the New Crown epidemic, to enhance detection efficiency, major manufacturers have introduced black technologies, including highly intelligent and automated equipment such as split-cup processing systems and fully automated nucleic acid extraction and purification instruments. One of the most prominent is the new crown nucleic acid rapid detection system, which is equipped with efficient amplification reagents and portable amplification instrument, able to complete the amplification process in about 30 minutes.
After continuous breakthroughs and innovations, some manufacturers have formed a perfect overall solution for nucleic acid detection of respiratory pathogens, including human boca virus, human metapneumovirus, human rhinovirus, influenza virus, Mycoplasma pneumoniae virus, etc. Acute respiratory tract infection is a common cause of human life and health hazards, rapid and accurate nucleic acid testing is important for the clinical diagnosis and control of respiratory tract infectious diseases.
