The specific application scenarios of the Virus Transport System (VTM-RT) mainly include the following aspects:

Clinical Diagnosis

• Detection of Respiratory Viruses: After collecting respiratory samples such as throat swabs and nasal swabs from patients, the VTM-RT is used to preserve and transport the samples, which can ensure the activity and nucleic acid integrity of influenza viruses, COVID-19 viruses, respiratory syncytial viruses, etc. This helps with subsequent nucleic acid testing, virus culture, etc., and enables timely and accurate diagnosis of respiratory infectious diseases.
• Detection of Enteric Viruses: For the diagnosis of enterovirus infections such as hand, foot, and mouth disease, the VTM-RT is used to collect and transport fecal samples, anal swab samples, etc. It can effectively maintain the survival state of the viruses and provide reliable samples for laboratory testing, improving the positive rate of detection and assisting clinicians in formulating reasonable treatment plans.
• Detection of Pathogens of Sexually Transmitted Diseases: When detecting pathogens of sexually transmitted diseases such as Neisseria gonorrhoeae, Chlamydia trachomatis, and human papillomavirus, the VTM-RT can be used to collect and transport samples of genital secretions, etc., ensuring the activity of the pathogens and the accuracy of detection, so as to facilitate early detection and treatment of diseases and prevent the spread of diseases.

Disease Surveillance and Prevention and Control

• Surveillance of Infectious Disease Outbreaks: During the outbreak of infectious diseases, such as influenza pandemics and the COVID-19 pandemic, a large number of samples need to be collected and transported quickly and safely. The VTM-RT can meet the needs of high-throughput sample collection and transportation, ensuring the quality of samples during transportation and providing timely and accurate data support for epidemic surveillance. It helps public health departments to grasp the epidemic trends and spread ranges and take effective prevention and control measures.
• Tracing the Source of Pathogens: When an infectious disease outbreak of unknown origin occurs, properly preserving and transporting the collected samples using the VTM-RT is beneficial for subsequent research such as gene sequencing and genotyping of the pathogens, tracing the origin and transmission routes of the viruses, and providing a scientific basis for epidemic prevention and control and source tracing.

Scientific Research Field

• Basic Research in Virology: When studying basic issues such as the biological characteristics, pathogenic mechanisms, and transmission patterns of viruses, a large number of virus samples need to be collected and processed. The VTM-RT can ensure the activity and integrity of the viruses in the samples, enabling researchers to observe and analyze the morphology, structure, growth curves, gene expression, and other characteristics of the viruses more accurately, providing strong support for basic research in virology.
• Drug Development and Vaccine Development: In the process of developing antiviral drugs and vaccines, real virus samples are needed for in vitro experiments and animal model studies. The VTM-RT can provide high-quality virus samples for evaluating the antiviral activity of drugs, the immunogenicity and protective effects of vaccines, etc., accelerating the R&D process of drugs and vaccines.

Biopharmaceutical Industry

• Production of Viral Vectors: In the fields of gene therapy and biopharmaceuticals, viral vectors are commonly used gene delivery tools. The VTM-RT can be used to collect and transport cell and virus samples used for the production of viral vectors, ensuring the quality and yield of viral vectors and providing a guarantee for the production of gene therapy drugs.
• Virus Culture in Vaccine Production: During the vaccine production process, a large number of viruses need to be cultured to prepare vaccines. The VTM-RT can help collect and transport the seed viruses used for virus culture and the virus samples collected at different production stages, ensuring the activity and stability of the viruses and ensuring the quality and safety of vaccines.
