A simple flu test could improve diagnosis and surveillance. The test, created by a group from the Expansive Establishment of MIT and Harvard and Princeton College, and upheld by the US Habitats for Infectious prevention and Counteraction, utilizes CRISPR to recognize the two fundamental sorts of occasional influenza, flu An and B . as well as the occasional influenza subtypes H1N1 and H3N2. It can likewise recognize strains impervious to antiviral treatment, and with additional exploration it might actually distinguish pig and bird influenza strains, including H5N1, which presently taints animals.
