WASHINGTON — A paper published by U.S. Centers for Disease Control and Prevention (CDC) scientists suggests that a new strain of swine flu has the potential to cause an outbreak, according to the Chicago Tribune.
Since September 2010, the H3N2 strain of the swine flu has infected at least 18 people and is now showing signs of potential human-to-human transmission, the article stated.
According to the article, the current seasonal flu vaccine would be ineffective against this up-and-coming strain, but the CDC is working on a vaccine for swine flu variants such as H3N2.
In November, the CDC suggested that "limited human-to-human transmission" of H3N2 had occurred in Iowa, but the most recent findings show that the virus is more easily transmissible than originally thought, the article noted.
