    There are things you can do right now to reduce your risk of falling seriously ill and dying from this disease.

    Dr. Greger: The severity of COVID-19 varies widely based on pre-existing conditions. Those with high blood pressure are at twice the odds of suffering a severe course, and those with cardiovascular disease have three times the odds. What’s more, those with either condition are about four times more likely to end up in the ICU. Those with COPD—chronic obstructive pulmonary diseases, like emphysema—appear to be at the highest risk, with six times the odds of a severe course for COVID-19, and nearly eighteen times the odds of an admission to the intensive care unit.

    We know that exposure to air pollution can increase susceptibility to respiratory viral infections, and that may be the case with COVID-19 as well, as higher pollutant levels appeared to be correlated with pandemic deaths. But just as air pollution may influence COVID-19, COVID-19 may be influencing air pollution. Check out this satellite data from NASA. This is nitrogen dioxide pollutant levels before the pandemic, then after lockdown. Here’s what ground zero, Wuhan province, looked like at around this time last time last year, and then post-pandemic. Ready for some irony? The decrease in air pollution following the quarantine is so great that the COVID-19 pandemic might paradoxically have decreased the total number of deaths by drastically decreasing the number of fatalities due to air pollution, averting as many as 30,000 deaths a month in China. In other words, the air quality in China was so bad that COVID-19 may have ended up saving lives—like 1,000 lives a day!

    A history of smoking is a risk factor for disease progression, though, surprisingly, active smoking may or may not be. This seeming paradox may provide a clue as to why those with high blood pressure appear to be at higher risk. ...
