NOTE: This document is provided for historical purposes only and may not reflect the most accurate and up-to-date information on this subject. For current flu information, please visit the CDC Flu Homepage.

Threat to Public Health from Influenza A (H2N2) is Low

CDC, HHS, and the World Health Organization are working with the College of American Pathologists (CAP) and other providers of proficiency testing panels to ensure that influenza A/H2N2 samples sent to U.S. laboratories and laboratories in 17 other countries are destroyed immediately. The A/H2N2 samples sent out are similar to the A/H2N2 viruses that circulated in humans in 1957 at the beginning of the Asian influenza pandemic. More information is provided in the links below:
