Yes, adenovirus is linked to obesity. Research has shown that certain strains of adenovirus can cause obesity in animals, and at least one strain is known to cause obesity in humans as well.
Adenoviruses, which are a type of virus that can cause respiratory and eye infections, are believed to be responsible for a small percentage of obesity cases. Specifically, a study published in the journal Nature Medicine in 2018 found that a strain of adenovirus called ad36 was linked to a higher risk of obesity in children and adults.
In the study, researchers looked at the medical records of more than 13,000 people in the United States between the ages of 2 and 85. They discovered that those who tested positive for ad36 were more than twice as likely to be obese compared to those who did not have the virus.
The study found that the virus appeared to be more common in individuals who were overweight or obese, suggesting the virus may play a role in the development of obesity. However, the researchers cautioned that more research is needed to fully understand the role of adenoviruses in obesity.
In addition to ad36, other strains of adenovirus, including ad5 and ad37, have been linked to obesity in animals. However, further research is needed to confirm whether these viruses have the same effect in humans.
Overall, there is evidence to suggest that adenoviruses may play a role in the development of obesity in humans. However, more research is needed to fully understand the link between adenoviruses and obesity.
