U.S. health officials said this past week that a mutated version of a common cold virus has caused 10 deaths in the last year and-a-half. Generally, the common cold is not thought of as a cause of death, except in those with severely weakened immune systems.

This version of an 'Adenovirus' has caused respiratory infections as a variant of a normal cold virus that, to this time, has caused about 140 illnesses in New York, Oregon, Washington and Texas.

The mutation, which was published in a report by the CDC, is not a threat to normal, healthy people, so no new precautions need to be taken by the public, according to the published report.
