Contemporary Influenza Virus Isolates
Influenza viruses pose a significant global public health challenge, often causing annual epidemics and occasional pandemics. Human infection with the influenza virus causes acute upper respiratory disease, potentially leading to hospitalization or death, particularly in older adults or those with certain chronic health conditions.1 Recognizing this impact, substantial efforts are directed toward preventing infection and limiting the virus's spread through population-wide vaccination, and other public health measures.
However, influenza viruses undergo frequent mutations, evolving both genetically and antigenically to escape host immune pressures, resulting in the emergence of new strains with the potential to evade immunity acquired from previous infections or vaccinations. Therefore, the availability of contemporary influenza strains is crucial for developing novel and effective diagnostics and therapies.
BEI Resources is now offering eleven recent influenza virus isolates originating from the United States. These include Influenza H3N2 and H1N1 subtype Influenza A viruses and Influenza B viruses of Victoria lineage. Derivative products including genomic RNA are in process and will be available soon.
