Epigenetics is a branch of science that could explain why some people develop severe covid and others do not.

The coronavirus pandemic has already infected more than 6.3 million people around the world, making it considered an unprecedented global health emergency.

Since the start of the covid-19 outbreak , attempts have been made to confront the disease from different flanks of science, with research and innovations within the different scientific branches to create a vaccine, a treatment or a tool that helps stop the spread of this infectious disease.

Among these branches of medicine that seek to fight coronavirus infection is epigenetics , an emerging field of science that studies hereditary changes caused by the activation and deactivation of genes without any change in the body’s DNA sequence..

In other words, epigenetics is in charge of analyzing the body’s reactions that are not determined by DNA, for example, the causes that cause each person to have a different immune response to an infection by the same virus or bacteria.

According to various specialists, epigenetic mechanisms can be modified by external factors that affect the expression of genes to certain stimuli, which would explain why some develop a severe coronavirus infection and others do not.

This external factors, also called environmental , can be stress, diet, UV exposure, drugs, drugs , alcohol, tobacco, maternal care, interpersonal relationships, attitude towards life, among other.

Because of this, epigenetics suggests that the way a person manages his life, responds to it and adopts habits, can determine how his body reacts to certain agents such as infection- causing viruses .

The epigenetic and coronavirus

Due to the above, various specialists have pointed out that the way in which coronavirus disease manifests depends on the epigenetic mechanisms of each individual, which can be affected by factors such as fear and anxiety derived from the pandemic emergency.
Bruce H. Lipton, a doctor in molecular biology, reported to ABC World that fear of a possible covid-19 infection , generated largely by the mitigation measures imposed and the treatment of information about coronavirus in the media, could be influencing a higher incidence of seriously ill patients.

According to the specialist, positive thoughts could influence the body’s epigenetic response, because if stress can provoke the appearance of diseases such as cardiovascular diseases, motivation could help to have a better immune response to infection.

“Through epigenetics and positive thinking, you can fight big pandemics like the new coronavirus. By changing the structure of thought”

Various investigations have analyzed the role of stress in the immune response to certain diseases , which could explain why some people asymptomatic of covid-19 infection , and others develop it as a fatal disease.
