Abstract

The invention belongs to the field of microbial molecular detection, and particularly relates to a kit for flavivirus quick typing and virus load detection. The kit for flavivirus quick typing and virus load detection comprises specific primers and probes for flaviviruses, including specific primers and a probe for dengue virus, specific primers and a probe for Zika virus, specific primers and a probe for yellow fever virus, and specific primers and a probe for Chikungunya virus. The kit for flavivirus quick typing and virus load detection has the advantages of high detection speed and accurate detection and quantification results, can simultaneously detect 3 different flavivirus pathogens and 1 togavirus pathogen capable of causing similar clinical symptoms at one time, can detect and diagnose flavivirus-pathogen-infected suspicious cases in time, and enhances the detection accuracy of flavivirus pathogen infection.

Description

technical field [0001] The invention belongs to the field of microbial molecular detection, in particular to a kit for rapid typing of flaviviruses and detection of viral load. Background technique [0002] Flaviviruses are widely distributed all over the world. They mainly transmit viruses through mosquito bites. They have the characteristics of fast transmission and serious illness, and cause serious harm to human beings and society. With the development of national trade and tourism, the inbound and outbound vehicles and goods surge, and the potential danger of mosquito-borne diseases is gradually increasing. There are many types of flaviviruses, how to detect and identify the types of flaviviruses in the shortest time is of great significance for clinical diagnosis and entry-exit inspection and quarantine. [0003] Traditional diagnostic methods for flaviviruses are mainly detected through serological tests, nucleic acid detection, virus culture or immunological detecti...
