But there is also evidence that our own genetics can protect us against certain pathogens or diseases.

It has become clear that this VIRUS affects older people to a greater extent. But this is not always the case, there have also been many cases of young or middle-aged people with a really serious medical condition. The genetics of each individual could explain this.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>But something we have known recently is that <strong>the virus appears to affect male patients more<\/strong>. Not only has it been seen that men are more likely to contract the disease, but it is also more likely to die. This could only be due to environmental factors that affect men more than women, such as a greater tendency to smoke, or have heart problems. Although the truth is that there are researchers who speculate that women have an immune system that defends better against COVID-19.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Also recently, we have learned that there is a relationship between <strong>blood group<\/strong> and sensitivity to COVID-19.
