Smokers may have more receptors for the new coronavirus

As if smoking weren’t bad enough for you, it seems the new coronavirus likes it, too. The lungs of people who smoke may contain more of the receptors that the new coronavirus uses to invade cells. This could explain why people with the virus who also smoke appear to be particularly vulnerable to severe illness.

The majority of people who acquire SARS-CoV-2, the virus that causes COVID-19, experience mild-to-moderate symptoms and will fully recover without hospital treatment.

However, several studies suggest that people who smoke are significantly more likely than people who do not to develop a severe form of the illness.

For example, according to a recent study of COVID-19 cases in hospitals in mainland China, 11.8% of people who smoked had a nonsevere form of the disease, while 16.9% had severe disease.

To break into cells and start replicating itself, the virus latches onto a protein receptor called angiotensin-converting enzyme 2 (ACE2), which is present in the cells’ membranes.

In a meta-analysis of studies that included 11,590 COVID patients, researchers found that among people with the virus, the risk of disease progression in those who currently smoke or previously smoked was nearly double that of non-smokers. They also found that when the disease worsens, current or former smokers had more acute or critical conditions or death. Overall, smoking was associated with almost a doubling of the risk of disease progressing.

As regular readers know, I feel strongly that smoking is an unmitigated blight on our lives. We lose over 170,000 people to it every year – just in lung cancer alone – totally preventable. To be honest, I am surprised that anyone who can read would choose to be a smoker. Nonetheless, it is so. I have a Page on it – How many ways does smoking harm you?   which I recommend you check out after reading this.

I am reproducing what follows from Medical News Today because I like the way they spell out positive aspects of ceasing smoking. Jenna Fletcher wrote it.

Cigarette smoking is one of the leading causes of preventable death in the United States. Despite this, some smokers find quitting daunting. They think it will take a very long time before seeing improvements in their health and well-being.

However, the timeline for seeing real benefits to quitting smoking is much faster than most people realize. Health benefits begin in as little as an hour after the last cigarette and continue to improve. Continue reading
