Coronavirus myth busted: Not being able to hold your breath for 10 seconds is not a confirmation of COVID-19
You may have COVID-19 if you have all the other symptoms of the infection even if you can hold your breath for more than 10 seconds.
Last week, a new coronavirus myth started circulating on social media platforms and is still doing the rounds. It said that if you can hold your breath for more than 10 seconds, it means you don’t have the new coronavirus infection. The post also said that coronavirus causes 50% fibrosis of lungs by the time the patient reaches the hospital.
The post was falsely attributed to Stanford University and some experts from Taiwan. On March 13, Stanford University tweeted, “Misinformation about COVID-19 symptoms and treatment falsely attributed to Stanford is circulating on social media and in email forwards. It is not from Stanford.”

A health expert from Stanford University also mailed the Associated Press (AP) saying that the post is fake and Stanford has nothing to do with it. The self-test is not a reliable way to say for sure that you have COVID-19.
Not a specific symptom
Lung fibrosis is a condition in which your lung tissue hardens due to formation of scar tissue, making it difficult to breathe properly.
Even though lung fibrosis is a symptom of severe lung diseases, about 80% of the COVID-19 patients get only mild symptoms. It is unlikely that they would get this level of lung damage this quickly.
Another Stanford expert told AP that various other health conditions may cause breathing difficulties which include heart disease, asthma and anxiety. And there is no concrete proof that COVID-19 can cause 50% fibrosis of lungs.
On the other hand, you may have COVID-19 if you have all the other symptoms of the infection — cough, fever, muscle aches — even if you can hold your breath for more than 10 seconds. You can also be asymptomatic - meaning that you have no symptoms at all but could still be contagious.
Fibrosis and pneumonia
Viral diseases and pneumonia are two of the risk factors for lung fibrosis. Though the exact cause of lung fibrosis remains unknown to date. Fibrosis is thought to occur when certain cells inside the lungs get reprogrammed somehow (due to environmental, genetic or unknown factors) and lead to the formation of scar tissue. Inflammation is also a possible cause of pulmonary fibrosis, but then inflammation can damage any organ where it occurs.
Besides, it takes anywhere between six months to several years before the signs of fibrosis start to show up. There isn’t much known about how COVID-19 affects the lung tissue yet.
Dr Junbo Ge, governor of American College of Cardiology's China chapter, who was studying the effects of COVID-19 on the heart, said in an online article on the website of the college that the patients may have some fibrosis after recovery. However, these reports are only based on the Chinese population and more studies are needed to confirm the theory.

"During our study, we couldn't detect viral particles in the cardiac tissues of COVID-19 patients, but what we found was tissue changes associated with DNA damage and repair,"
Most of the cases have been reported from North 24 Parganas, Howrah, Kolkata, Hooghly, Murshidabad, South 24 Parganas, Jalpaiguri and Darjeeling districts
