Of the newly announced cases, two were confirmed to have a vaping-related injury, while in three cases vaping was thought to be the probable cause of an injury, according to the Massachusetts Department of Public Health in a release.
MA has gone the farthest, issuing a four-month ban on all vaping products - flavored or not.
"Prior to the outbreak of lung injury associated with vaping in Wisconsin and IL this past August, vaping-associated lung injuries were unreported and not tracked by public health agencies", said Dr. Tom Safranek, State Epidemiologist for DHHS. Of those cases, 51 are now being investigated, with state officials collecting medical records and conducting patient interviews.
While the specific cause of the nationwide outbreak of lung injuries remains unknown, health officials are zeroing in on potential clues.

There are now 800 confirmed and probable cases of severe lung illnesses in 46 U.S. states and the U.S. Virgin Islands, the health department said. The ages of patients range from 15 to 51, officials said.
Many patients who got sick said they vaped both nicotine and THC, and about 16 percent said they vaped nicotine e-cigarettes exclusively. "Twenty-two cases did not meet the official CDC definitions". A task force report on vaping is expected later this week.
The Centers for Disease Control and Prevention said last month its investigation into the outbreak is looking at products containing the marijuana compound THC. "However, we do not know whether the only risky substance for lung injury is the THC-containing products".
Among the 10 confirmed and probable cases, most patients are under the age of 20 (50 percent) and between the ages of 40 and 49 (30 percent).
The CDC, state health departments, and the federal Food and Drug Administration are all still investigating the causes of these diseases.
