But those lung injuries haven't gone away, and signs of e-cigarette or vaping product use-associated lung injury (EVALI) can look a lot like a COVID-19 infection, federal and state health officials warn, healthday.com reported.
Eight cases of EVALI were reported in California in April, during the early days of the COVID-19 pandemic, according to a new report from the California Department of Public Health and the US Centers for Disease Control and Prevention (CDC).
"Teens didn't stop vaping because of COVID," said Dr. Jamie Garfield, a pulmonary care doctor in Philadelphia and volunteer spokeswoman for the American Lung Association. But doctors may not be looking for EVALI much anymore, she said. Garfield was not involved with the new study.
"When the prevalence of any disease is really high, everything that quacks like a duck is a duck, and in March and April, everything that sort of looked like COVID was COVID. This is where history-taking becomes very important. You have to know if a kid is vaping and what they're vaping," Garfield explained.
EVALI symptoms include: Shortness of breath, fever and chills, cough vomiting, diarrhea, headache, dizziness, rapid heart rate and chest pain
The CDC stopped tracking EVALI in mid-February, because cases appeared to be waning after a September peak. As of Feb. 18, more than 2,800 people in the US had been hospitalized with life-threatening lung damage tied to e-cigarette use, the CDC said. Sixty-eight died.
Research into these cases strongly suggests that an additive called vitamin E acetate, which is sometimes used in pot-laced vapes, triggers EVALI, the CDC said.
A recent US study estimated that one in 10 middle and high school kids in the US had vaped within the past month. At some schools, e-cigarette use was as high as 60 percent, according to findings published online recently in the Journal of Adolescent Health.
According to the new CDC report, the eight California EVALI patients went to the hospital about four days after symptoms began. Their average age was 17. Six said they had vaped THC (the psychoactive ingredient in marijuana).
Four of the teens needed intensive care and two needed mechanical ventilation to breathe. None tested positive for COVID-19, study author Dr. Christina Armatas, of the California Department of Public Health, and her colleagues noted.
These were the first cases reported in California since February. The researchers said it wasn't clear if EVALI cases had been missed in March. The findings were published in the CDC's Morbidity and Mortality Weekly Report.
Dr. Len Horovitz, a pulmonologist at Lenox Hill Hospital in New York City, noted that people with EVALI could also have COVID-19. He said it's not clear whether vaping increases susceptibility to the new coronavirus, but it definitely increases the risk for COVID-19 complications. No one should be vaping, he added.
"There's never been a place for vaping. Just because it's legal doesn't mean it's OK," Horovitz said.
Garfield agreed. "Vaping is not a safe alternative to smoking. Anything you put into your lungs besides clear air can increase your risk of lung injury," she said.
