Coronavirus and Blood Type – level 1
Four types of blood exist. The blood types are A, B, AB and 0. Every type is different. The blood type can affect some diseases.
In the past, scientists discover that many people with SARS have blood type A. Scientists think that the blood type can affect the coronavirus, too. Scientists in the UK study thousands of people with COVID-19. 2,000 people have serious COVID-19. Thousands of other people have only mild COVID-19.
Scientists compare these people´s blood types. The result is very interesting. People with blood type A have more health problems and more serious COVID-19. People with blood type 0 do not have so many health problems. Sometimes, people with blood type 0 have no COVID-19 symptoms at all.
Difficult words: SARS (a serious disease that makes problems with breathing), compare (to check more things and see how similar or different they are), symptom (when you can tell that you have a certain disease because of how you feel or look).
