The present invention relates to a novel genotype of severe fever with thrombocytopenia syndrome viruses and use thereof as an immunogenic composition. The severe fever with thrombocytopenia syndrome viruses of the present invention are genetically different from conventional severe fever with thrombocytopenia syndrome viruses and are novel viruses taxonomically belonging to three sub-groups of genotype B. In view of the vaccine property that specific genotype viruses alone show only limited protective potential, the novel viruses of the present invention may be advantageously used as a vaccine having excellent cross-immunogenicity for SFTSV.

Provided are a marker for detecting a highly pathogenic influenza virus including a protein mutant prepared by substituting the amino acids 68 and 69 of a PB1-F2 protein, a composition for detecting a highly pathogenic virus including an agent for measuring the protein mutant, and a detection kit including the same, a method for detecting a highly pathogenic virus including measuring the protein mutant, an antiviral composition against influenza A virus including an inhibitor of binding between a PB1-F2 protein in which the amino acids 68 and 69 are substituted and DDX3, and a method for screening an antiviral substance against influenza A virus.

An early infectious disease sign detection device includes: an early infectious disease sign detection unit that generates early sign information indicating an early sign that a determination target patient is going to develop an infectious disease, by using learning data indicating a result of learning about biological information of a patient who has developed the infectious disease among a plurality of patients, and biological information acquired for the determination target patient; and an action information output unit that outputs action information for the infectious disease for the determination target patient, based on the early sign information.

A field effect transistor (FET) biosensor for virus detection of a selected virus within a sample volume is disclosed. The FET comprises a semiconductor substrate, a source and drain electrode on the substrate, the electrodes spaced to form a channel. A gate electrode carried on the substrate and located in the channel between the source and drain electrodes. An insulating layer is coupled to a top surface of the gate electrode and a bottom surface of the source and drain electrodes, with an open channel above the insulating layer. A channel material is coupled to the insulating layer. Aptamers are oriented within the open channel to bind to the channel material and with the selected virus to enable a detection of the selected virus by the FET biosensor based on a change in drain-source current at a selected gate voltage.
