‘Compelling evidence’ linking smoking to increased risk of Covid-19 diagnosis


Today smokers are also more likely to have a higher burden of symptoms than non-smokers.

Public health officials should include smoking cessation programs in the fight against Covid-19, a study concluded.

The recommendation was made after researchers found that people who smoked were more likely to show up in the hospital with symptoms of Covid-19 than non-smokers.

Smokers are now more likely to have a higher symptom burden than non-smokers, according to investigators from King’s College London (KCL) in the United Kingdom (UK).

Writing to Thorax (‘Current risk of smoking and Covid-19: consequences from an app symptoms in a population of over 2.4 million people’, doi: 10.1136 / thoraxjnl-2020-216422), Steves and so on said smokers were 29 percent more likely to moreport more than five Covid-19-related symptoms and 50 percent more likely to moreport more than 10 symptoms, including loss of odor, skipping eating, diarrhea, fatigue, confusion, or muscle pain.

The more symptoms suggested the more severe Covid-19, they added.

Current smokers who test positive for the deadly virus are also twice as likely as non -smokers to go to the hospital.

The researchers concluded that smoking cessation programs were a key part of Government-led anti-Covid-19 strategies.

They also advised that any reduction in smoking rates in the general population would also reduce the burden on health systems from other smoking-related conditions that require hospitalization.

“The evidence that current smoking appears to be increasing individual and therefore the burden on the health system from Covid-19 is a strong argument for governments to speed up rather than stop measures to provide plans. to control tobacco, “they wrote in the online edition of the journal.

“Our results provide strong evidence for an association between current smoking and individual risk from Covid-19, including self-reported symptom burden and risk of going to hospital. Smoking cessation should be included in public health campaigns and other efforts to address the Covid-19 pandemic. “

Data collected between March-April 2020 from the Covid-19 Symptom Study app in the UK were used in the study.

Lead researcher Dr Claire Steves, a consultant doctor and Reader at the School of Life Science Course, KCL, said: “As Covid-19 rates continue to rise and the National Health Service is moving towards capacity , it is important that we do everything we can to minimize its effects and find ways to reduce hospital admissions.
