Oct 11 (Reuters) - Indiana on Thursday confirmed two more deaths from a mysterious lung illness linked to e-cigarettes, bringing the total number of fatalities to 29 across the country, as U.S. health officials investigate the outbreak that has shown no signs of easing.

Latest data from the Centers for Disease Control and Prevention (CDC) listed 1,299 confirmed and probable cases of the illness as of Oct. 8. (http://bit.ly/2IlMmo5)

CDC last month urged people to not use e-cigarettes with marijuana ingredient tetrahydrocannabinol (THC), saying that the high-inducing component may have a role in causing the illness.

U.S. health officials said on Friday there may be more than one cause for the outbreak of the illness and said they do not see a meaningful drop in the number of new cases.
