Health officials say a study in dogs found an increased risk of lung cancer among people with chronic fatigue syndrome.
The study also found that people with the disease had a higher risk of contracting the coronavirus, a disease with no symptoms but which is linked to respiratory illness and cancer.
The researchers said the findings have implications for people with Toxos who are trying to manage their symptoms, or who are currently taking antibiotics or other medicines that may affect the immune system.
“The results are not surprising given the fact that chronic fatigue is an illness with a high fatality rate and an associated increased risk for lung cancer,” said the study’s lead author, Dr. Ayelet Waldron, an infectious disease specialist at the Hebrew University of Jerusalem.
The authors wrote that “the increased risk observed in this study was consistent with the data on Toxoviruses and cancer in dogs from a previous study in humans.”
It’s unclear why chronic fatigue was elevated in dogs, although Waldron said the finding could be due to the immune response to the virus.
Toxox is a virus that causes the symptoms of chronic fatigue and is passed on to humans through the feces of infected animals.
In dogs, it has been linked to the spread of coronaviruses such as Toxoparasites, which can cause lung and liver cancers in people with asthma and other respiratory illnesses.
The Centers for Disease Control and Prevention says that chronic pain, muscle aches, and other symptoms associated with chronic disease are common among people affected by the T. gondii coronaviral infection.
In its 2014 report, the agency said that in humans, the virus is associated with increased rates of cardiovascular disease, cancer, and diabetes.
