A new study from The BMJ suggests that there are four main risk factors that predict when people with new coronavirus infection are prone to severe symptoms,media reported. In fact, a more special aspect of the new coronavirus is that some patients do not show symptoms at all, while others will soon find themselves attacking most of their major organs.
According to the study, the four factors that cause severe symptoms in patients with the new coronavirus include age, sex, weight and underlying disease. Not surprisingly, in the past two months we have seen a lot of evidence — men over 70 are particularly vulnerable to the virus. There are also reports that people with obesity or other potential health problems, such as diabetes, are particularly vulnerable to the virus.
The study involved more than 20,000 patients in 208 hospitals in the UK, probably one of the largest of its kind to date. Over a two-and-a-half-month period, the study found that the median age of patients admitted to hospital with symptoms of the new coronavirus was 73. The study also found that 60 percent of new coronavirus patients were male.
It is clear that the vast majority of patients with severe coronavirus symptoms have serious potential health complications, of which heart disease is the most common. Other common potential health problems include diabetes and chronic kidney disease.
Overall, the report found that age, male sex and common diseases, including chronic heart disease, non-asthma chronic lung disease, chronic kidney disease, liver disease and obesity, were associated with increased hospitalization mortality. “

Another chart helps illustrate the most common symptoms of the new coronavirus in patients who go to the hospital. The five most common symptoms, as shown in the figure below, are cough, fever, shortness of breath, fatigue and mental disorders.
Related, another study by Imperial College London found that smokers with symptoms of the new coronavirus were more than 14 per cent more likely to end up in hospital than non-smokers. Specifically, the study shows that smoking tends to increase the number of ACE2 receptors in the respiratory tract, which ultimately makes it easier for the new coronavirus to take root in the body.
Finally, it’s worth noting that another recent study of the new coronavirus found that most people with new coronary pneumonia are no longer contagious 11 days after the first symptoms.
