We have experienced severe coronavirus infections before: SARS and MERS were both caused by coronaviruses. Luckily, we experienced these outbreaks during a time when genetics is a flourishing scientific industry. We use genetics for everything from cancer treatments and research to determining paternity. We also use genetics to study the spread of diseases. Fairly extensive studies were made on both SARS and MERS, both on the viruses themselves and on some of the patients who suffered through those illnesses. Genetics allows us to see just how much genetic material is shared between those outbreak viruses and SARS-CoVID-2, the virus that causes the illness known as COVID-19. It also allows us to do large scale determinations, including seeing how patients are similar and different in relation to how severe they experience the illness. To simplify: it allows researchers to find genes that make us more resilient or susceptible to severe coronavirus illnesses. Continue reading to learn more about this revelation!
